Subject: [PATCH 0001/1148] feat: better logic & dependencies between profile
 sync, auth, user storage & notifications (#5275)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR improves the logic & dependencies between profile syncing, auth,
user storage and notifications.
It makes the necessary changes for the below list to hold true:

- Profile syncing is - for now - only account syncing
- Disabling profile syncing should only disable profile syncing features
(i.e: account syncing).
- User storage methods should still be callable if profile syncing is
**OFF**, **IF** a user is authenticated
- User storage methods should **NOT** be callable **ONLY IF** the user
is **NOT** authenticated
- `UserStorageController` should not have control over
`NotificationServicesController`
- `NotificationServicesController` should not have control over
`UserStorageController`
- Notifications shouldn’t depend on profile syncing, they only depend on
auth & user storage
- Enabling Notifications should sign a user **in** if they weren’t
before, so they can use user storage methods

## References

Fixes:
- https://consensyssoftware.atlassian.net/browse/IDENTITY-10
- https://consensyssoftware.atlassian.net/browse/IDENTITY-11

## Changelog

### `@metamask/profile-syncing-controller`

- **CHANGED**: `isProfileSyncingEnabled` now only affects profile
syncing features (i.e Account syncing)
- **CHANGED**: Being authenticated is now the only pre-requisite for
calling user storage methods

### `@metamask/notification-services-controller`

- **ADDED**: Enabling notifications will now sign a user in if they
weren't already
- **REMOVED**: `NotificationServicesController` is not able to enable
profile syncing anymore

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0002/1148] feat: remove metametrics dependencies in
 UserStorageController (#5278)

## Explanation

This PR removes MetaMetrics dependencies in `UserStorageController` as
those are needed only for `AuthenticationController`.

## References

Fixes: https://consensyssoftware.atlassian.net/browse/IDENTITY-15

## Changelog

### `@metamask/profile-sync-controller`

- **BREAKING**: Remove MetaMetrics dependencies from
`UserStorageController`

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0004/1148] feat: add multichain assets controller (#5138)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR adds the new MultichainAssetsController. This controller manages
non-evm tokens and metadata.

- [x] Subscribing to `AccountsController:accountAdded` event and fetch
assets for the account and update state accordingly
- [x] Subscribing to `AccountsController:accountRemoved` event and
remove assets from state
- [x] Fetching assets metadata after fetching assets for a new account
- [x] Subscribing to `AccountsController:accountAssetListUpdated` and
Update account assets with removed or added assets.
- [ ] Update all assets metadata once a day (not part of V1 can be done
on a separate PR to unblock other teams 🙏 )

methods, replacing them with the V2 `BaseController`, its derived
classes, and helper methods.

This is the culmination of work completed over multiple quarters, and
represents a major step forward for performative and best
practice-compliant state management in our clients.

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

## `@metamask/base-controller`

### Changed

- Widen input parameter for type guard `isBaseController` from
`ControllerInstance` to `unknown`.

### Removed

- **BREAKING:** Remove class `BaseControllerV1` and type guard
`isBaseControllerV1`.
- **BREAKING:** Remove types `BaseConfig`, `BaseControllerV1Instance`,
`BaseState`, `ConfigConstraintV1`, `Listener`, `StateConstraintV1`,
`LegacyControllerStateConstraint`, `ControllerInstance`.

## `@metamask/composable-controller`

### Changed

- **BREAKING:** Re-define `ComposableControllerStateConstraint` type
using `StateConstraint` instead of `LegacyControllerStateConstraint`.
- **BREAKING:** Constrain the `ComposableControllerState` generic
argument for the `ComposableController` class using
`ComposableControllerStateConstraint` instead of
`LegacyComposableControllerStateConstraint`.

## `@metamask/polling-controller`

### Removed

- **BREAKING:** Remove `BlockTrackerPollingControllerV1`,
`StaticIntervalPollingControllerV1`.

## Checklist

Subject: [PATCH 0008/1148] breaking: Remove deprecated messenger-related
 exports and aliases (#5260)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This PR removes several deprecated exports and aliases from the
`base-controller` package to simplify the codebase and reduce confusion.
The following changes are made:

- Remove `ControllerMessenger` export (was an alias for `Messenger`)
- Remove `RestrictedControllerMessenger` export (was an alias for
`RestrictedMessenger`)
- Remove `RestrictedControllerMessengerConstraint` type export (was an
alias for `RestrictedMessengerConstraint`)
- Simplify `RestrictedMessenger` constructor by removing the deprecated
`controllerMessenger` parameter in favor of using only the `messenger`
parameter

These aliases were originally introduced to help with migration but are
no longer needed

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Subject: [PATCH 0009/1148] chore: update multichain controllers to listen for
 new update events (#5221)

## Explanation

We are updating the `MultichainBalancesController` and
`MultichainTransactionsController` to listen for the update
balances/transactions events from `AccountsController`:

`AccountsController:accountBalancesUpdated`
`AccountsController:accountTransactionsUpdated`

Also from now own we are changing the approach, to stop doing the
polling requests to the snaps, and just listen for these update events,
hence removing the associated poll logic.

## References

N/A

## Changelog

### `@metamask/multichain-transactions-controller`
- ** CHANGED**: Listen for transactions update events and remove polling
logic

### `@metamask/assets-controllers`
- ** CHANGED**: Listen for balances update events and remove polling
logic in `MultichainBalancesController`
-

Subject: [PATCH 0014/1148] chore: export controller messenger type to index
 (#5296)

## Explanation

We are not explicitly exporting the
`TokenSearchDiscoveryControllerMessenger` type from package index and
therefor consumers are forced to import from the common js module.

<!--

* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?

Subject: [PATCH 0015/1148] chore: Improve tag fetching in create-update-issues
 workflow (#5299)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?

* If your primary goal was to update one package but you found you had

* If you had to upgrade a dependency, why did you do so?
-->

This PR modifies how tags are fetched in the create-update-issues
workflow by replacing the `fetch-tags` input parameter with an explicit
`git fetch` command.

- Removed `fetch-tags: true` from checkout action
- Added separate step to fetch tags using `git fetch --prune --unshallow
--tags`

This change provides more explicit control over tag fetching and ensures
we get a complete tag history with pruning of stale refs.

Subject: [PATCH 0016/1148] chore: get assets list from
 MultichainAssetsController state (#5295)

## Explanation

We are getting the full list of assets for an account via the
MultichainAssetsController state, instead of only requesting the native
token.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/assets-controllers`

- **ADDED**: Adds the ability to request for all the assets that an
account can have

Subject: [PATCH 0017/1148] fix: multichainToken rate for non evm (#5175)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This pull request introduces the `MultiChainTokensRatesController`, a
new controller that manages multi‑chain token conversion rates within
MetaMask. Its primary goal is to periodically poll for updated
conversion rates of tokens associated with non‑EVM accounts (those using
Snap metadata), ensuring that the conversion data remains up‑to‑date
across supported chains.

**Key changes and features include:**

- **Polling Mechanism:**
The controller extends `StaticIntervalPollingController` to run periodic
polls (default interval of 3 min). During each poll, it triggers an
update of token conversion rates for the currently selected account if
it is active (i.e. if the keyring is unlocked).

- **State Management & Mutex Locking:**
The controller stores conversion rates in its state (`conversionRates`),
which is updated atomically using a mutex (from `async-mutex`) to
prevent race conditions during concurrent updates.

- **Event Subscriptions:**
- **Keyring Events:** Listens to `KeyringController:lock` and
`KeyringController:unlock` events to track if the keyring is active.
- **Accounts Events:** Subscribes to
`AccountsController:selectedAccountChange` to update the current account
and trigger a conversion rate update, and to
`AccountsController:accountRemoved` to clean up any state associated
with a removed account.

- **Account Filtering:**
The controller retrieves all multichain accounts from the
AccountsController and filters out non‑EVM accounts that have Snap
metadata. Currently, only accounts of type `'solana:data-account'` are
supported for conversion updates, with a TODO note indicating future
Snap support enhancements.

- **Integration with Snap:**
Conversion updates involve sending a Snap request using a helper method
(`#handleSnapRequest`) to the SnapController. It builds a list of asset
conversion pairs (from asset to USD via the Swift ISO4217 code) and then
updates its state with the returned conversion rates.

- **Keyring Client Support:**
A dedicated helper (`#getClient`) instantiates a `KeyringClient` to
route keyring-related JSON-RPC requests through the SnapController,
ensuring a consistent integration with MetaMask’s underlying snap
infrastructure.

- **Type Safety & Messaging:**
Comprehensive TypeScript types are provided for controller state,
actions, events, and the messenger interface. This guarantees that
interactions with other controllers (such as the AccountsController,
KeyringController, and Snaps-related modules) are type‑safe and
well‑documented.

Overall, this controller enhances the MetaMask architecture by adding
robust support for multi‑chain tokens, ensuring that users with non‑EVM
accounts receive updated conversion rate information in a timely and
thread‑safe manner.

Subject: [PATCH 0018/1148] feat: support type 4 transactions (#5285)

## Explanation

Support EIP-7702 / type 4 transactions including `authorizationList` via
the `TransactionController`.

Specifically:

- Upgrade `ethereumjs/tx` and `ethereumjs/common`.
- Add `setCode` to `TransactionEnvelopeType`.
- Add `authorizationList` to `TransactionParams`.
- Complete and sign all authorizations using `KeyringController` before
signing transaction.
- Prevent type 4 transactions if origin is not `ORIGIN_METAMASK`.
- Validate `authorizationList` property before approval request.
- Centralise prepare and serialization logic into `prepare.ts` utils.
- Encapsulate all EIP-7702 specific logic in new `eip7702.ts` util.

_Currently using a local messenger action type for the signing. To be
replaced once available in the `KeyringController`._

## References

Fixes [#4095](https://github.com/MetaMask/MetaMask-planning/issues/4095)

## Changelog

### `@metamask/transaction-controller`

- **ADDED**: Add `setCode` to `TransactionEnvelopeType`.
- **ADDED**: Add `authorizationList` to `TransactionParams`.
- **CHANGED**: Bump `ethereumjs/tx` to `^5.4.0`.
- **CHANGED**: Bump `ethereumjs/common` to `^4.4.0`.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0019/1148] refactor(accounts-controller)!: revert wildcard
 export (#5300)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Using a wildcard export in the root `index.ts` of a package is,
regrettably, not an ideal practice. This file is very useful because it
gives us a way to understand everything that a package publicly exports
at a glance.

In using a wildcard export, however, we lose this visibility. Because
all symbols marked with `export` will automatically become exports of
the package, it is possible to introduce a new export without even
knowing about it. We also lose the ability to export a symbol purely for
internal purposes, which is useful for tests.

As it relates to the change being reverted, because of the introduction
of this wildcard export, new exports have been introduced which will now
need to be reverted in a new major version, namely `AllowedActions` and
`AllowedEvents`. This is non-ideal; we should not have to introduce
major versions if we do not need to, because they are disruptive.

Elsewhere it was noted that needing to add an export manually to this
list is a small pain point especially if other subdirectories also use
`index.ts`. I would argue that not knowing about exports (regardless of
at which level exports occur) creates _more_ trouble in the long run.
That is, the small pain point is a intentional feature and not a bug :)

+### Added
+
+- Add new `MultiChainTokensRatesController` ([#5175](https://github.com/MetaMask/core/pull/5175))
+  - A controller that manages multi‑chain token conversion rates within MetaMask. Its primary goal is to periodically poll for updated conversion rates of tokens associated with non‑EVM accounts (those using Snap metadata), ensuring that the conversion data remains up‑to‑date across supported chains.
+- Add `updateBalance` to MultichainBalancesController ([#5295](https://github.com/MetaMask/core/pull/5295))
+
+### Changed
+
+- **BREAKING:** MultichainBalancesController messenger must now allow `MultichainAssetsController:getState` action and `MultichainAssetsController:stateChange` event ([#5295](https://github.com/MetaMask/core/pull/5295))
+- Update `MultichainBalancesController` to get the full list of assets from `MultichainAssetsController` state instead of only requesting the native token ([#5295](https://github.com/MetaMask/core/pull/5295))
+- Bump `@metamask/base-controller` from `^7.1.1` to `^8.0.0` ([#5305](https://github.com/MetaMask/core/pull/5305))
+- Bump `@metamask/polling-controller` from `^12.0.2` to `^12.0.3` ([#5305](https://github.com/MetaMask/core/pull/5305))
+
+### Removed
+
+- **BREAKING:** `NETWORK_ASSETS_MAP`, `MultichainNetworks`, and `MultichainNativeAssets` are no longer exported ([#5295](https://github.com/MetaMask/core/pull/5295))

   - This controller manages the retrieval and caching of remote feature flags. It fetches feature flags from a remote API, caches them, and provides methods to access and manage these flags. The controller ensures that feature flags are refreshed based on a specified interval and handles cases where the controller is disabled or the network is unavailable.

No specific error is thrown when an operation that requires an unlocked
vault is attempted while `KeyringController.state.isUnlocked` is false.
This doesn't make the operations possible, but it doesn't give a clear
error message either.

This PR adds an assertion on almost all `KeyringController` methods to
check if the controller is unlocked and to throw an error when it isn't.

Subject: [PATCH 0022/1148] feat: add new keyring type for oneKey (#5216)

## Explanation

This PR adds support for a dedicated OneKey keyring (until now it was
sharing the same keyring instance than Trezor) so it's considered as a
standalone device and could get its own tag inside account list.

There are two others PRs:
- metamask-extension:
https://github.com/MetaMask/metamask-extension/pull/29999
- eth-trezor-keyring: https://github.com/MetaMask/accounts/pull/175

## References

Fixes: https://github.com/MetaMask/accounts-planning/issues/793

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory

consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/accounts-controller`

- **utils**: add OneKey keyring type
- **tests**: update accounts controller unit test with OneKey keyring
type

### `@metamask/keyring-controller`

- **controller**: add OneKey keyring type

## Checklist

Subject: [PATCH 0023/1148] Release 298.0.0 (#5314)

Release for the support of OneKey devices.

Those devices were already supported, but they will use a new specific
keyring `OneKeyKeyring` to distinguish them from normal Trezor devices.
Both keyring shares the same logic and the same bridge logic too.

Subject: [PATCH 0025/1148] Fix invalid type import path in
 `@metamask/multichain` (#5313)

## Explanation

`@metamask/multichain` was importing `src/scope/types`, which does not
work when importing the library in other projects. I've changed it to
`../scope/types` instead.

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".

Subject: [PATCH 0026/1148] chore: Change ownership of
 SelectedNetworkController (#5312)

## Explanation

The package `@metamask/selected-network-controller` is now owned solely
by the Wallet API Platform team, rather than being shared between
multiple teams. This team has the most context for what this code does,
and it will in the future be increasingly less relevant to the rest of
the wallet apart from supporting the EIP-1193 provider.

Subject: [PATCH 0027/1148] RpcService: Regard node-fetch errors as retriable
 (#5298)

Currently we have tests for middleware to verify that requests get
retried when certain errors are thrown. In a future commit we will
replace the retry logic in these middleware with RpcService, and when
this happens the aforementioned tests will break. This is because we are
using Nock to force the request to throw errors, and in tests we use
`node-fetch` to polyfill the `fetch` function, and `node-fetch` errors
are not regarded as retriable by RpcService.

This commit adjusts RpcService to treat `node-fetch` errors as retriable
(but making sure to exclude errors from Nock itself, since they will
also manifest as `node-fetch` errors).

Subject: [PATCH 0028/1148] feat: Add `MultichainNetworkController` to handle
 both EVM and non-EVM network and account switching (#5215)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR updates both the MultichainNetworkController and
AccountsController to handle network switching as well as account
switching. The logic handles the following logic:
- Switching accounts on AccountsController will notify
MultichainNetworkController to update if the account belongs to evm vs
non-evm network (MultichainNetworkController subscribes to
AccountsController event)
- Switching between networks on MultichainNetworkController will notify
AccountsController to update accounts based on which network the account
belongs to (AccountsController subscribes to MultichainNetworkController
event)



## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/accounts-controller`

- **BREAKING**:
- Added `MultichainNetworkController:networkDidChange` to allowed
events. This is used to subscribe to the `setActiveNetwork` event from
the `MultichainNetworkController` and is responsible for updating
selected account based on network changes (both EVM and non-EVM).

### `@metamask/multichain-network-controller`

- **ADDED**:
- Allowed actions - `NetworkControllerGetStateAction` |
`NetworkControllerSetActiveNetworkAction`. The
`MultichainNetworkController` acts as a proxy for the
`NetworkController` and will update it based on EVM network changes.
- Allowed events - `AccountsControllerSelectedAccountChangeEvent` to
allowed events. This is used to subscribe to the `selectedAccountChange`
event from the `AccountsController` and is responsible for updating
active network based on account changes (both EVM and non-EVM).

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0029/1148] feat: Re-simulate active transactions every 3000 ms
 (#5189)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR adds `ResimulateHelper`, which focuses on
`transactionMeta.isActive` property and re-simulates transaction
depending on that value.

In order to capsulate re-simulation logic, this PR also relocates other
utility functions under the new created `ResimulationHelper.ts` file.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

Extension PR: https://github.com/MetaMask/metamask-extension/pull/29878

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/transaction-controller`

- **ADDED**: Adds ability of re-simulating transaction depending on the
`isActive` property on `transactionMeta`
   - `isActive` property is expected to set by client.
- Re-simulation of transactions will occur every 3 seconds if `isActive`
is `true`.
- Adds `setTransactionActive` function to update the `isActive` property
on `transactionMeta`.

## Checklist

- [X] I've updated the test suite for new or updated code as appropriate
- [X] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [X] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [X] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0030/1148] fix: change maxNumberOfAccountsToAdd default value
 from 100 to Infinity (#5322)

## Explanation

This PR changes the default value for account syncing's
`maxNumberOfAccountsToAdd` from `100` to `Infinity`.
It will become the client's responsibility to set this number to a
specific value. If not specified, account sync will synchronize every
account.

Subject: [PATCH 0031/1148] feat: better handle notification account tracking
 on wallet unlock (#5323)

## Explanation

Our constructor fired account calls even when the wallet was locked.
We added similar logic as push notifications to ensure we only make the
initialise call after the wallet is unlocked.

Subject: [PATCH 0033/1148] fix: fix account controller legacy polling (#5321)

## Explanation
Changes were made to accountTrackerController inside the
@metamask/assets-controllers package.

The account tracker polling was executed on the constructor with the
initialisation. This caused additional requests to be sent by the app,
leading to performance issues.

Additionally, the accountTracker was still using legacy polling via the
poll function. This function has now been removed, and a test has been
added to prevent the creation of multiple polling instances.

These changes improve efficiency by reducing unnecessary network
requests and ensuring the polling mechanism is properly controlled.

FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/assets-controllers`

- **CHANGED**: Removed legacy poll function to prevent redundant
polling.
- **FIXED**: ensure that the polling is not triggered on the constructor
with the initialisation


## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0035/1148] fix: fix peer deps for
 `@metamask/{accounts,multichain-network}-controller` (#5327)

## Explanation

The 2 controllers depend on each other, however we cannot really express
this with peer deps.

So for now, we only declare this "relation" on the new controller
`mutltichain-network-controller`.

Also downgrading some peer dep to use the major version.

Subject: [PATCH 0036/1148] feat: bridge controller (#5276)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR adds a new controller: `BridgeController`.

This controller handles the quote fetching and polling from the Bridge
API.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

This is a port of the `BridgeController` from Extension:
https://github.com/MetaMask/metamask-extension/tree/main/app/scripts/controllers/bridge

Some minor changes were needed to fill in the missing functions and
variables from Extension.

This package will be consumed initially by the Metamask Mobile
application first. Eventually, we wish to migrate the Extension to use
this `core/bridge-controller` package.

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/bridge-controller`

- **<ADDED>**: New `BridgeController`!

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0037/1148] feat: add optional `validateAgainstSchema` option
 when creating user storage entry paths (#5326)

## Explanation

This PR adds a new `validateAgainstSchema` option when creating user
storage entry paths.
This defaults to true, but can be relaxed to false when using the SDK.
SDK users should use the feature and key names they decide to use, and
Controller users should follow the internal schema.

## References

Related to: https://consensyssoftware.atlassian.net/browse/IDENTITY-31

## Changelog

### `@metamask/profile-sync-controller`

- **ADDED**: Optional `validateAgainstSchema` option when creating user
storage entry paths

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This is a controller release that includes the first version of the
`MultichainNetworkController`, which also include `AccountController`
updates. The other version bumps are related to updating their peer
dependency version of accounts controller.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

From f8c8a90a9b29a8b2966ac5324d220e044a1b30b9 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0039/1148] Create RPC middleware using RPC services (#5290)

When creating the middleware stack for a network, NetworkController
makes use of functions from two packages for sending requests:

- `createInfuraMiddleware` from `@metamask/eth-json-rpc-infura` for
Infura networks
- `createFetchMiddleware` from `@metamask/eth-json-rpc-middleware` for
custom RPC endpoints

Currently, each of these middleware implements similar heuristics for
determining when the network is down and retrying requests
appropriately. We want to improve upon this logic so that we incorporate
the circuit breaker pattern, exponential backoff, and jitter for
retries, and, in the case of Infura, we can fail over to an alternate
RPC endpoint when it is down. To make this happen, we have implemented
an RpcService class which extracts all of this logic into one place. As
a result, we can vastly simplify the Infura and fetch middleware
creation functions so that they only need to take an RPC service and the
RPC service will handle the rest.

To accommodate these changes, this commit:

- Upgrades the `@metamask/eth-json-rpc-infura` and
`@metamask/eth-json-rpc-middleware` packages to allow an RPC service to
be passed.
- Adds two new required options to NetworkController, `fetch` and
`btoa`. These are also requirements of RpcService and allows consumers
to pass in whatever versions of these functions is specific to their
platform.
- Updates `createAutoManagedNetworkClient` to take `fetch` and `btoa`
and pass them along to `createNetworkClient`.
- Updates `createNetworkClient` to create an RPC service and pass it
along to the two middleware creation functions. Consequently, these
functions now handle requests in exactly the same way.

 ## [Unreleased]
 
+### Added
+
+- Implement circuit breaker pattern when retrying requests to Infura and custom RPC endpoints ([#5290](https://github.com/MetaMask/core/pull/5290))
+  - If the network is perceived to be down after 5 attempts, further retries will be paused for 30 seconds
+  - "Down" means the following:
+    - A failure to reach the network (exact error depending on platform / HTTP client)
+    - The request responds with a non-JSON-parseable or non-JSON-RPC-compatible body
+    - The request returns a non-200 response
+- Use exponential backoff / jitter when retrying requests to Infura and custom RPC endpoints ([#5290](https://github.com/MetaMask/core/pull/5290))
+  - As requests are retried, the delay between retries will increase exponentially (using random variance to prevent bursts)
+
+### Changed
+
+- **BREAKING:** `NetworkController` constructor now takes two required options, `fetch` and `btoa` ([#5290](https://github.com/MetaMask/core/pull/5290))
+  - These are passed along to functions that create the JSON-RPC middleware
+- Synchronize retry logic and error handling behavior between Infura and custom RPC endpoints ([#5290](https://github.com/MetaMask/core/pull/5290))
+  - A request to a custom endpoint that returns a 418 response will no longer return a JSON-RPC response with the error "Request is being rate limited"
+  - A request to a custom endpoint that returns a 429 response now returns a JSON-RPC response with the error "Request is being rate limited"
+  - A request to a custom endpoint that throws an "ECONNRESET" error will now be retried up to 5 times
+  - A request to a Infura endpoint that fails more than 5 times in a row will now respond with a JSON-RPC error that encompasses the failure instead of hiding it as "InfuraProvider - cannot complete request. All retries exhausted"
+  - A request to a Infura endpoint that returns a non-retriable, non-2xx response will now respond with a JSON-RPC error that has the underling message "Non-200 status code: '\<code\>'" rather than including the raw response from the endpoint
+  - A request to a custom endpoint that fails with a retriable error more than 5 times in a row will now respond with a JSON-RPC error that encompasses the failure instead of returning an empty response
+  - A "retriable error" is now regarded as the following:
+    - A failure to reach the network (exact error depending on platform / HTTP client)
+    - The request responds with a non-JSON-parseable or non-JSON-RPC-compatible body
+    - The request returns a 503 or 504 response
+- Bump dependencies to support usage of RPC services internally for network requests ([#5290](https://github.com/MetaMask/core/pull/5290))
+  - Bump `@metamask/eth-json-rpc-infura` to `^10.1.0`
+  - Bump `@metamask/eth-json-rpc-middleware` to `^15.1.0`
+
 ## [22.2.1]

Subject: [PATCH 0041/1148] Use Prettier 2 for Jest (#5330)

## Explanation

Jest doesn't support Prettier 3, so after the migration to ESLint 9
(requiring Prettier 3), Jest snapshots could no longer be created or
updated. The recommended solution by Jest is to add `prettier-2` as
separate dependency and referencing that in the config.

Subject: [PATCH 0043/1148] Discourage the use of barrel exports (#5304)

Barrel exports seem like a good idea, but they hamper maintainability in
the long run. Unfortunately we don't have a guideline around this in our
contributor documentation, so this commit adds such a guideline. It also
links to the existing docs from `contributing.md`.

+# Guidelines for Packages
+
+## List exports explicitly
+
+Every package in this monorepo should have an `index.ts` file in the `src/` directory. Any symbols that this file exports will be usable by consumers.
+
+It is tempting to save time by re-exporting all symbols from one or many files by using the "wildcard" or ["barrel"](https://basarat.gitbook.io/typescript/main-1/barrel) export syntax:
+
+🚫
+
+```typescript
+export * from './foo-controller';
+export * from './foo-service';
+```
+
+However, using this syntax is not advised for the following reasons:
+
+- Barrel exports make it difficult to understand the public surface area of a package at a glance. This is nice for general development, but is especially important for debugging when sorting through previously published versions of the package on a site such as `npmfs.com`.
+- Any time a new export is added to one of these files, it will automatically become an export of the package. That may sound like a benefit, but this makes it very easy to increase the surface area of the package without knowing it.
+- Sometimes it is useful to export a symbol from a file for testing purposes but not expose it publicly to consumers. With barrel exports, however, this is impossible.
+
+Instead of using barrel exports, name every export explicitly:
+
+✅
+
+```typescript
+export { FooController } from './foo-controller';
+export type { FooControllerMessenger } from './foo-controller';
+export { FooService } from './foo-service';
+export { FooService } from './foo-service';
+export type { AbstractFooService } from './foo-service';

Subject: [PATCH 0047/1148] Export generateDeterministicRandomNumber for use
 within mobile (#5341)

## Explanation

The purpose of this PR is to export the `remote-feature-flag-controller`
method `generateDeterministicRandomNumber` for use within the UI. I am
not inserting it as a controller method because we should not need to
instantiate the controller in order to use it.

Subject: [PATCH 0049/1148] feat: support atomic batch transactions (#5306)

## Explanation

Support atomic batch transactions via EIP-7702, and ERC-7821.

Specifically:

- Add `addTransactionBatch` method with `TransactionBatchRequest` and
`TransactionBatchResult` types.
- Encode multiple transactions into single `execute` call using ERC-7821
ABI.
- Automatically upgrade account via `setCode` transaction if needed.
- Add `isAtomicBatchSupported` method to identify which chains support
atomic batch for a given account.
- Add new `batch` `TransactionType`.
- Add `batch` utils to encapsulate all batch-related logic.
- Add `feature-flags` utils to encapsulate retrieval and fallback of
LaunchDarkly configuration.
  - Currently EIP-7702 chains and contract addresses.
- Validate `to` of external transaction is not an internal account
unless `transactionType` is `batch`.

## References

Fixes [#4096](https://github.com/MetaMask/MetaMask-planning/issues/4096)

## Changelog

See `CHANGELOG.md`.

Subject: [PATCH 0050/1148] chore: fix selected-network-controller CODEOWNERS
 (#5349)

## Explanation

The Wallet Framework team must be co-owners of all `package.json` and
`CHANGELOG.md` to ease releases.

It's only important for transversal version bumps (like when bumping
`@metamask/utils`.

Subject: [PATCH 0051/1148] Support keyring metadata in KeyringController
 (#5112)

## Explanation

Currently, we assume that the only HD Keyring is the Primary Keyring.
Most methods related to adding accounts or displaying the SRP assume
that it refers to the first keyring, which is the Primary Keyring. To
enable having more than one SRP, and consequently more than one HD
Keyring, this PR adds an array called `keyringsMetadata`, which contains
an id that can be used to identify all keyrings and a proper place to
keep other data we might want to add to each keyring such as `name`.

`keyringsMetadata` is a separate in order to minimize changes that we
need to make to keyrings and the way we process them. We also can keep
this data outside of the vault, as it's not storing any sensitive data.

Subject: [PATCH 0053/1148] feat: add `signEip7702Authorization` to
 `KeyringController` (#5301)

EIP-7702 defines a new struct Authorization which represents authority
to set a pointer to a contract address at an EOA - effectively making
the EOA perform as a smart contract.

This change integrates the new `signEip7702Authorization` method added
to eth- simple and hd keyrings in
https://github.com/MetaMask/accounts/pull/182. This is exposed via
`KeyringController.signEip7702Authorization` as well as the message
handler `KeyringController:SignEip7702Authorization`.

See https://github.com/ethereum/EIPs/blob/master/EIPS/eip-7702.md for
details

Subject: [PATCH 0054/1148] chore: Add missing CODEOWNER package rules (#5351)

## Explanation

CODEOWNER rules have been added for all packages that are currently
missing them:

* `example-controllers`: These are examples maintained by the wallet
framework team.
* `mutlichain-network-controller`: This package has been a collaboration
between many teams, but for now the owners have been set to the same as
the `network-controller` plus the accounts team (who proposed this
controller's creation). We can change this further if appropriate.


## References

The `multichain-network-controller` package was added here:
https://github.com/MetaMask/core/pull/5215

## Changelog

N/A

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

 - Initial release of the RemoteFeatureFlagController. ([#4931](https://github.com/MetaMask/core/pull/4931))
   - This controller manages the retrieval and caching of remote feature flags. It fetches feature flags from a remote API, caches them, and provides methods to access and manage these flags. The controller ensures that feature flags are refreshed based on a specified interval and handles cases where the controller is disabled or the network is unavailable.

Subject: [PATCH 0056/1148] feat: use `KeyringController:withKeyring` for
 account syncing operations (#5345)

## Explanation

This PR does two things related to account syncing:

- use `KeyringController:withKeyring` to add accounts in bulk instead of
one by one
- This will vastly improve client performance by being able to batch RPC
calls that previously happened sequentially when we added accounts one
by one
- This will permit to remove the maximum accounts to sync limit in
clients
- use `KeyringController:withKeyring` to filter and care only about the
primary SRP's HD Keyring accounts
- This doesn't change the current implementation and functionality, but
will ensure that nothing will break when multi-SRP releases

This PR doesn't introduce breaking changes.

## References

Fixes: https://consensyssoftware.atlassian.net/browse/IDENTITY-6
Related to: https://consensyssoftware.atlassian.net/browse/IDENTITY-28
Draft extension PR:
https://github.com/MetaMask/metamask-extension/pull/30317

## Changelog

### `@metamask/profile-sync-controller`

- **CHANGED**: Account syncing - add accounts in bulk instead of one by
one
- **CHANGED**: Account syncing - filter and care only about the primary
SRP's HD Keyring accounts

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0059/1148] Add top gainers losers to token discovery service
 (#5309)

## Explanation

We're introducing methods that allow consumers to fetch top-gainers and
top-losers from the portfolio api (ultimately via the Moralis service).

I've also consolidated some of the types in this PR so they are reusable
and provided a base type inheritance.

### `@metamask/package-a`

- **Added**: param types inherit from a `ParamsBase`
- **Added**: `getTopGainersByChains` to the `TokenDiscoveryApiService`
- **Added**: `getTopLosersByChains` to the `TokenDiscoveryApiService`

- **Changed**: - **BREAKING:** Renamed `TokenTrendingResponseItem` name
to `MoralisTokenResponseItem`
- Consumer will get ts compilation errors after upgrading until they
update their imports

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0060/1148] chore: bump
 `@metamask/keyring-{snap-client,internal-api}` versions (#5356)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

Some of the versions were not "aligned", resulting in different
`keyring-api` versions (nothing too breaking though), but this sometimes
pollutes the lavamoat policy files once updating the controllers on the
extension, so it's "better" to keep them aligned as much as we can.

Was:

```
├─ @metamask/assets-controllers@workspace:packages/assets-controllers
│  ├─ @metamask/keyring-api@npm:17.0.0 (via npm:^17.0.0)
│  ├─ @metamask/keyring-internal-api@npm:4.0.2 (via npm:^4.0.1)
│  └─ @metamask/keyring-snap-client@npm:3.0.3 [d7116] (via npm:^3.0.3 [d7116])
│     └─ @metamask/keyring-api@npm:16.1.0 (via npm:^16.1.0)
...
├─ @metamask/multichain-transactions-controller@workspace:packages/multichain-transactions-controller
│  ├─ @metamask/keyring-api@npm:17.0.0 (via npm:^17.0.0)
│  ├─ @metamask/keyring-controller@workspace:packages/keyring-controller (via npm:^19.1.0)
│  ├─ @metamask/keyring-internal-api@npm:4.0.2 (via npm:^4.0.1)
│  └─ @metamask/keyring-snap-client@npm:3.0.3 [f7262] (via npm:^3.0.3 [f7262])
│     └─ @metamask/keyring-api@npm:16.1.0 (via npm:^16.1.0)
```

While the `keyring-api` being used everywhere else is the `17.0.0`.

Subject: [PATCH 0061/1148] ci: Add CODEOWNER constraints (#5352)

## Explanation

Add Yarn constraints to ensure each package has a designated owner, and
that any non-wallet-frameowrk packages have the wallet framework team
set as co-owners of release related files.

Subject: [PATCH 0062/1148] feat: optimise push controller API calls (#5358)

## Explanation

Our new backend change allows us to ditch the "Pull then Push" approach
for push notification registration links.
So we can remove 1 query in our enable/disable/update notifications
flow.

There are still many more API calls we make (notifications flow talks
back and forth between 4/5 services), but at least this is a first step.

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/notification-services-controller`

- **REMOVED**: the `getPushNotificationLinks` API call as this is not
needed due to backend optimizations.

Subject: [PATCH 0063/1148] refactor(keyring-controller): ensure authorization
 contract address is provided (#5353)

#5301 introduced a new method for signing EIP-7702 Authorizations.

This change adds validation to ensure that `contractAddress` is
specified, rather than type asserting the `contractAddress` to `Hex`.

Subject: [PATCH 0065/1148] chore: updates handleOnAccountTransactionsUpdated
 (#5339)

## Explanation

We were assuming that controller would get all transactions for an
account in the update event, but we just get new/updated transactions,
therefore we need to take that into account in the method.
The key improvements are:

- Handles the update of transactions by using a Map to deduplicate them
by Id (newer versions replace older ones)
- Preserves existing transactions
- Sorts transactions by timestamp (newest first)

Subject: [PATCH 0066/1148] fix: process first call to update the rates
 controller then start polling (#5364)

## Explanation
We observed that once the rate controller is initialized, polling does
not begin until the default interval of three minutes has passed,
causing the rate to only be retrieved after that delay. This leads to a
suboptimal user experience. This pull request addresses the issue by
manually triggering a rate update.

<!--
Thanks for your contribution! Take a moment to answer these questions so

your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".

### `@metamask/assets-controllers`

- **FIXED**: Resolved an issue where rate polling would only begin after
the default 3-minute interval by manually triggering a rate update upon
initialization, ensuring an immediate refresh for a better user
experience

Subject: [PATCH 0068/1148] Feat/bridge status controller (#5317)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?

unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR adds a new controller: `BridgeStatusController`.

This controller handles the bridge transaction status fetching and
polling from the Bridge API.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

This is a port of the `BridgeStatusController` from Extension:
https://github.com/MetaMask/metamask-extension/tree/main/app/scripts/controllers/bridge-status

Some minor changes were needed to fill in the missing functions and
variables from Extension.

This package will be consumed initially by the Metamask Mobile
application first. Eventually, we wish to migrate the Extension to use
this `core/bridge-status-controller` package.

Very closely related to the `BridgeController`:
https://github.com/MetaMask/core/pull/5276

### `@metamask/bridge-status-controller`

- ADDED: New `BridgeStatusController`!

### `@metamask/bridge-controller`
- CHANGED: `BridgeController` `FeeType` enum now exported as an enum,
not just a type

## Checklist

Subject: [PATCH 0070/1148] Release/305.0.0 (#5367)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so

* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR performs the initial releases for the `bridge-controller` and
`bridge-status-controller` for consumption in Mobile. Both were ported
from Extension with some minor changes to get them to work without
Extension-specific code. Test coverage has also been improved over the
Extension versions.

Subject: [PATCH 0072/1148] fix: not call the snap to get rates if assets are
 empty (#5370)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation
This pull request aims to update the `multichainAssetsRatesController`
so that if the assets list is empty, the Snap call is skipped and
execution returns immediately.

Subject: [PATCH 0073/1148] feat: update notification services to support
 mobile. (#5120)

## Explanation

This is a large PR that enables support for push notifications on
mobile.

**Makes Push Notification Controller Platform Agnostic**

The `NotificationServicesPushController` was highly tied to web and was
not compatible for react-native.
We now have isolated the web logic in`web/push-utils.ts`, and allow
platforms to overwrite and inject a push service into the controller.
E.g. Mobile can inject push services using react-native modules.

**Add support to toggle push notifications on/off in isolation**

This allows us to decouple in-app notifications from push notifications.
It is done by adding a `isPushEnabled` boolean inside the
`NotificationServicesPushController`.

We have also added public methods `enablePushNotifications` and
`disablePushNotifications` inside the `NotificationServicesController`
to allow us tie it to UI Actions.

## References

## Changelog

### `@metamask/notification-services-controller`

- **ADDED**: `isPushEnabled` state to
`NotificationServicesPushControllerState` to enable and disable this
controller/
- **ADDED**: `isUpdatingFCMToken` state to
`NotificationServicesPushControllerState` to track when the controller
is updating for firebase registration token.
- **ADDED**: `PushService` interface and default web implementation for
push notifciations
- **CHANGED (BREAKING)**: `NotificationServicesPushController` config
now allows injecting of a `PushService` interface during controller
creation.
- **ADDED**: `/push-services/web` subpath export to import web specific
push services.
- **ADDED**: `/shared` folder including some shared utils used in
controllers for this package.
- **ADDED**: public method `enablePushNotifications` and
`disablePushNotifications` in `NotificationServicesController` to enable
and disable push notifications in isolation.

Subject: [PATCH 0074/1148] feat: STAKE-942: add pooled staking vault daily
 apys and vault apy averages to earn controller (#5368)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This PR adds the pooled staking `VaultDailyApys` and `VaultApyAverages`
state and related refresh methods to the `EarnController`.

Also,`vaultData` state has been renamed to `vaultMetadata` to
differentiate it from other vault-related state.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

Subject: [PATCH 0076/1148] fix: make sure wallet scope does not insert
 accounts (#5374)

## Explanation

This pull request fixes [this
issue](https://github.com/MetaMask/MetaMask-planning/issues/4263).

We appear to be adding an `account` to the wallet scope

Resulting in this failing
[CI](https://app.circleci.com/pipelines/github/MetaMask/metamask-extension/125517/workflows/abdfdb4f-da74-4cc2-9c2f-cf001817f358/jobs/4559282)
for our [Multichain Flask
PR](https://github.com/MetaMask/metamask-extension/pull/27782)

we should add it to the `wallet:eip155` scope (as currently done), but
not just `wallet`.

The fix involves refactoring [core](https://github.com/MetaMask/core)
Multichain package so that creating the `scopeObjects` for each entry,
we make sure that in `wallet` scope string, the accounts property is not
populated.

+## Usage
+
+You can import the controllers via the main npm path.
+
+```ts
+import { ... } from '@metamask/profile-sync-controller'
+```
+
+This package also uses subpath exports, which help minimize the amount of code you wish to import. It also helps keep specific modules isolated, and can be used to import specific code (e.g. mocks). You can see all the exports in the [`package.json`](./package.json), but here are a few.
+
+Importing specific controllers/modules:
+
+```ts
+// Import the AuthenticationController and access its types/utilities
+import { ... } from '@metamask/profile-sync-controller/auth'
+
+// Import the UserStorageController and access its types/utilities
+import { ... } from '@metamask/profile-sync-controller/user-storage'
+
+// Import the profile-sync SDK and access its types/utilities
+import { ... } from '@metamask/profile-sync-controller/sdk'
+```
+
+Importing mock creation functions:
+
+```ts
+// Import and use mock creation functions (designed to mirror the actual types).
+// Useful for testing or Storybook development.
+import { ... } from '@metamask/profile-sync-controller/auth/mocks'
+import { ... } from '@metamask/profile-sync-controller/user-storage/mocks'
+```

+## Usage
+
+This package uses subpath exports, which helps to minimize the amount of code you need to import. It also helps to keep specific modules isolated and can be used to import specific code (e.g., mocks or platform-specific code). You can see all the exports in the [`package.json`](./package.json), but here are a few examples:
+
+Importing specific controllers/modules:
+
+```ts
+// Import the NotificationServicesController and its associated types/utilities.
+import { ... } from '@metamask/notification-services-controller/notification-services'
+
+// Import the NotificationServicesPushController and its associated types/utilities.
+import { ... } from '@metamask/notification-services-controller/push-services'
+```
+
+Importing mock creation functions:
+
+```ts
+// Import and use mock creation functions (designed to mirror the actual types).
+// Useful for testing or Storybook development.
+import { ... } from '@metamask/notification-services-controller/notification-services/mocks'
+import { ... } from '@metamask/notification-services-controller/push-services/mocks'
+```
+
+Importing platform specific code:
+
+```ts
+// Some controllers provide interfaces for injecting platform-specific code, tailored to different clients (e.g., web or mobile).
+import { ... } from '@metamask/notification-services-controller/push-services/web'
+```
+

Subject: [PATCH 0081/1148] feat: add mobile feature flags and fix tests
 (#5359)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR adds `mobileConfig` to the feature flags that `BridgeController`
fetches to support the native Bridge experience on Mobile.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/bridge-controller`

- ADDED: `mobileConfig` field added to `bridgeFeatureFlags`

## Checklist

Subject: [PATCH 0082/1148] fix(5383): flaky user-segmentation-utils
 distribution test fix (#5384)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
The previous approach used `Math.floor()` for bucket assignment
```
const bucketIndex = Math.floor(value buckets);
distribution[bucketIndex === buckets ? buckets - 1 : bucketIndex] += 1;
```
This created edge case issues where values near bucket boundaries (like
0.299 vs 0.301) could fall into different buckets. With random number
generation, these edge cases would sometimes cluster differently between
test runs, causing sporadic failures.
- 0.299 → bucket 2
- 0.301 → bucket 3
(Even though they're very close values)

While the new approach consistently handles them:
- 0.299 → explicitly in range [0.2, 0.3]
- 0.301 → explicitly in range [0.3, 0.4]

Key improvements:
1. **Explicit Range Boundaries**: Clear `min` and `max` values for each
range, eliminating ambiguity at boundaries
2. **Better Edge Case Handling**: Values are explicitly checked against
range boundaries rather than using floor division

This explicit range handling makes the test more deterministic and less
susceptible to edge-case clustering.

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

Subject: [PATCH 0083/1148] test(accounts-controller): remove duplicated test
 mock function (#5387)

## Explanation

We had a duplicated function to create mocked account. One of them was
not handling the new `scopes` properly. So this is just a refactor to
merge both of these functions together while also fixing the logic for
future-PRs to come.

 ### Changed
 
+- **BREAKING:** `addNewKeyring` method now returns `Promise<KeyringMetadata>` instead of `Promise<unknown>` ([#5372](https://github.com/MetaMask/core/pull/5372))
+  - Consumers can use the returned `KeyringMetadata.id` to access the created keyring instance via `withKeyring`.
+- **BREAKING:** `withKeyring` method now requires a callback argument of type `({ keyring: SelectedKeyring; metadata: KeyringMetadata }) => Promise<CallbackResult>` ([#5372](https://github.com/MetaMask/core/pull/5372))
 - Bump `@metamask/keyring-api"` from `^17.0.0` to `^17.2.0` ([#5366](https://github.com/MetaMask/core/pull/5366))
 - Bump `@metamask/keyring-internal-api` from `^4.0.1` to `^4.0.3` ([#5356](https://github.com/MetaMask/core/pull/5356)), ([#5366](https://github.com/MetaMask/core/pull/5366))

Subject: [PATCH 0085/1148] Integrate RPC failover into NetworkController
 (#5360)

When configuring a network, a list of failover endpoint URLs can now be
supplied. If the network is perceived to be down (after 15 unsuccessful
attempts to make a request) then the request will be forwarded
automatically to the first failover URL (using subsequent URLs as
failovers for previous URLs).

Under the hood, the list of failover URLs are loaded into an
RpcServiceChain (added in a previous commit) and this is then passed to
the Infura or fetch middleware.

Subject: [PATCH 0087/1148] feat: create merger and factory for the
 Caip25Permission (#5283)

## Explanation
Addressing https://github.com/MetaMask/MetaMask-planning/issues/4017

We want to create a merger for the Caip25Permission specification in
order to enable wallet_addEthereumChain and wallet_switchEthereumChain
to call to the PermissionController rather than the ApprovalController
for incremental permission requests (i.e. for the permittedChains flow).

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/multichain-api`

- **BREAKING**: Renamed `mergeScopes` to `mergeNormalizedScopes`
- ADDED: Added merger to CaveatSpecification returned by
`caip25CaveatBuilder()`
- ADDED: Added `mergeInternalScopes` which merges two
`InternalScopesObject`s

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0088/1148] Release/311.0.0 (#5391)

## Explanation

This is a release for the `@metamask/multichain` to create a merger for
the Caip25Permission specification in order to enable
wallet_addEthereumChain and wallet_switchEthereumChain to call to the
PermissionController rather than the ApprovalController for incremental
permission requests (i.e. for the permittedChains flow).

This includes a breaking change, as a function exported from the package
`mergeScopes` is now being exported as `mergeNormalizedScopes`, to
differentiate from the newly added and available `mergeInternalScopes`.

Subject: [PATCH 0089/1148] feat: add dapp scanning functionality (#5319)

## Explanation
This feature introduces support to the PhishingController to scan
whether a URL is malicious from the MetaMask dapp scanning endpoint. It
will strip the URLs and only send the hostname. The response will return
a recommended action (NONE, WARN, BLOCK).

Subject: [PATCH 0090/1148] feat: add support for locales on push notifications
 (#5392)

## Explanation

This allows server push notifications to support different locales.

## References

## Changelog

### `@metamask/notification-services-controller`

- **ADDED**: `getLocale` to `NotificationServicesPushController` config.
- **ADDED**: `locale` field to our request payload when sending
registration tokens.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0091/1148] refactor(accounts-controller): use `account.scopes`
 in `listMultichainAccounts` (#5388)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

Now that accounts have their own `scopes` we should use those while
filtering (rather than relying on the account's type).

## References

Requires:
- [x] https://github.com/MetaMask/core/pull/5387

Testing PR:
- https://github.com/MetaMask/metamask-extension/pull/30551 (CI is 🟢)

## Changelog

### `@metamask/account-controller`

- **CHANGED**: Use `account.scopes` in `listMultichainAccounts`

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0092/1148] Release 312.0.0 (#5399)

Release to update/re-adapt the logic of
`AccountsController:listMultichainAccounts`. We used to rely on the
`account.type` to do some filtering (this was before the introduction of
`account.scopes`).

The logic has been adapted to use the `account.scopes`, which is more
robust and **correct** implementation.

There should not be any impacts for existing accounts with the exception
of Bitcoin accounts that uses different scopes for mainnet and testnet
(Bitcoin support has been disabled temporarily on the extension).

From 1b35e865acfacd76b45fc818e4e5abfa3fcf3d93 Mon Sep 17 00:00:00 2001
From: Matthew Walsh <matthew.walsh@consensys.net>
Date: Wed, 26 Feb 2025 21:21:51 +0000
Subject: [PATCH 0093/1148] feat: validate nested transactions are not to

Throw if `addTransactionBatch` is called with any nested transaction
with a `to` matching an internal account.

Also fix `@metamask/remote-feature-flag-controller` dependency.

## References

## Changelog

See `CHANGELOG.md`.

Subject: [PATCH 0094/1148] Release/313.0.0 (#5403)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This release introduces `scanUrl` to the PhishingController which scans
whether a URL is malicious from the MetaMask dapp scanning endpoint. It
will strip the URLs and only send the hostname. The response will return
a recommended action (NONE, WARN, BLOCK).

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".

Subject: [PATCH 0095/1148] fix: Add MANTLE support for conversion rates
 (#5402)

## Explanation

Inspecting extension shows that we fetch the conversion rate using this
URL:
https://min-api.cryptocompare.com/data/price?fsym=ETH&tsyms=MNT

This is incorrect as it is not using the correct symbol override. The
url should be:
https://min-api.cryptocompare.com/data/price?fsym=ETH&tsyms=MANTLE

This gives a much better unsupported conversion number that what it
currently is.

Subject: [PATCH 0097/1148] chore: change bridge state structure to have all
 fields at root of state (#5406)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR changes the state shape of `BridgeController` and
`BridgeStatusController` to better match the standard shape with all the
relevant fields at the root of `state` rather than behind a redundant
field like `state.bridgeState` or `state.bridgeStatusState`.

It also changes the default values from `undefined` to `null` to better
support Mobile efforts.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/bridge-controller`

- BREAKING: Data fields have been moved to the root of the `state`
object, rather than behind a redundant field `state.bridgeState`
- BREAKING: Default values have been changed from `undefined` to `null`.

### `@metamask/bridge-status-controller`

- BREAKING: Data fields have been moved to the root of the `state`
object, rather than behind a redundant field `state.bridgeStatusState`
- BREAKING: Redundant type `BridgeStatusState` removed from exports

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

The controller ensures that feature flags are refreshed based on a specified interval and handles cases where the controller is disabled or the network is unavailable.

Subject: [PATCH 0102/1148] Chore/bridge bridge status superstruct (#5408)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR refactors the `BridgeController` and `BridgeStatusController` to
use Superstruct for increased readability of API response validators.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--

if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".

Subject: [PATCH 0104/1148] chore: bump keyring packages (#5405)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR bumps these packages across the core controllers:
- `@metamask/eth-simple-keyring`
- `@metamask/eth-hd-keyring`
- `@metamask/keyring-internal-api`

The package is being updated on Extension by this PR:
https://github.com/MetaMask/metamask-extension/pull/30637

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".

Subject: [PATCH 0106/1148] chore: switch over to @ethersproject packages at
 5.7.0 for mobile compat (#5416)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Mobile uses Ethers v5 libs so in order to align better with that we will
be downgrading from v6 to v5 in the `BridgeController`.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/bridge-controller`

- **BREAKING**: Change `ethers` v6 dependency to `@ethersproject`
subpackages at v5 for better Mobile compatibility. This changes the
`ethers` v6 native JS `bigint` return values to `ethers` v5 `BigNumber`
values.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0111/1148] Add `getAssetMetadata` action to
 `MultichainAssetsController` (#5430)

## Explanation

This adds an action to the `MultichainAssetsController` called
`getAssetMetada` which allows to get a specific asset Metadata.

Subject: [PATCH 0114/1148] refactor: profile sync controllers should consume
 SDK methods (#5413)

## Explanation

This PR makes the necessary changes so that `UserStorageController` and
`AuthenticationController` consumes the profile sync SDK.
That means that there's no longer controller specific logic nor services
related to authentication and user storage.
Test coverages has also been increased to almost 100% for all things
related to authentication and user storage, for controller & SDK.

## References

Related to: https://consensyssoftware.atlassian.net/browse/IDENTITY-48
Extension test drive PR:
https://github.com/MetaMask/metamask-extension/pull/30681

Note that when bumping the version on the extension and mobile, some
changes will be mandatory:
- Updating the mock storage key for both identity and notifications E2E
tests constants
- Updating `sessionData` shapes everywhere
- Add a migration to manage `sessionData` shape changes so that it is
reset for users still using the previous shape
- Bumping `KeyringController` to `^19.2.1` if not done already, and take
care of the breaking changes this version adds on extension
- This will most likely be fixed with
https://github.com/MetaMask/metamask-extension/pull/30637

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/profile-sync-controller`

- **CHANGED**: `UserStorageController` and `AuthenticationController`
now use the SDK under the hood.
- **CHANGED**(**BREAKING**): `AuthenticationController` state entry
`sessionData` has changed shape to fully reflect the `LoginResponse` SDK
type.
- **CHANGED**(**BREAKING**): `UserStorageController` cannot use the
`'AuthenticationController:performSignOut'` action anymore.

### `@metamask/notification-services-controller`

- **CHANGED**: Change import for mock access token (only related to
tests)

## Checklist

Subject: [PATCH 0117/1148] refactor: migrate wallet handlers (and unit tests)
 (#5420)

## Explanation

[Original
ticket](https://github.com/MetaMask/MetaMask-planning/issues/4335)

Part of the scope of
https://github.com/MetaMask/MetaMask-planning/issues/4129 is having the
currently existing handlers for:

`wallet_getPermissions`
`wallet_revokePermissions`
`wallet_requestPermissions`

Available in the mobile codebase.

This raises an issue, where if future changes are required in any of
these handlers, those would need to be done on both extension and mobile
codebases, instead of having one single source of truth. Therefore, as
part of this https://github.com/MetaMask/MetaMask-planning/issues/4129,
we could extract the existing handlers on extension repo over to core
and create a release for that so they can be imported in whichever code
base needs them.

As part of this work, create another refactor ticket for these to later
be imported on extension repo and removed from that codebase altogether
(not urgent at the moment).

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".

Subject: [PATCH 0118/1148] Release/318.0.0 (#5435)

## Explanation

- Updates the @metamask/multichain package to use new hooks provided by
the Snaps MultichainRouter to enable non-evm support on the Multichain
API. ([#5191](https://github.com/MetaMask/core/pull/5191))
- Migrates wallet permission handlers from `extension` repo.
([#5420](https://github.com/MetaMask/core/pull/5420))

## Changelog

- **BREAKING**: `getSessionScopes()` now expects an additional hooks
object as its last param. The hooks object should have a
`getNonEvmSupportedMethods` property whose value should be a function
that accepts a `CaipChainId` and returns an array of supported methods.
([#5191](https://github.com/MetaMask/core/pull/5191))
- **BREAKING**: `caip25CaveatBuilder()` now expects two additional
properties it's singular param object. The param object should now also
have a `isNonEvmScopeSupported` property whose value should be a
function that accepts a `CaipChainId` and returns a boolean, and a
`getNonEvmAccountAddresses` property whose value should be a function
that accepts a `CaipChainId` and returns an array of CAIP-10 account
addresses. ([#5191](https://github.com/MetaMask/core/pull/5191))
- The CAIP-25 caveat specification now also validates if non-evm scopes
and accounts are supported
- **BREAKING**: The `wallet_getSession` handler now expects
`getNonEvmSupportedMethods` to be provided in it's hooks.
([#5191](https://github.com/MetaMask/core/pull/5191))
- The handler now resolves methods for non-evm scopes in the returned
`sessionScopes` result
- **BREAKING**: The `wallet_invokeMethod` handler now expects
`getNonEvmSupportedMethods` and `handleNonEvmRequestForOrigin` to be
provided in it's hooks. `handleNonEvmRequestForOrigin` should be a
function with the following signature:
  - ```
     handleNonEvmRequestForOrigin: (params: {
       connectedAddresses: CaipAccountId[];
       scope: CaipChainId;
       request: JsonRpcRequest;
     }) => Promise<Json>;
    ```
  - The handler now supports handling non-evm requests
- **BREAKING**: `assertScopeSupported()` now expects the following hooks
params object as it's last param:
  - ```
      {
       isChainIdSupported: (chainId: Hex) => boolean;
       isEvmChainIdSupported: (chainId: Hex) => boolean;
       isNonEvmScopeSupported: (scope: CaipChainId) => boolean;
       getNonEvmSupportedMethods: (scope: CaipChainId) => string[];
     }
    ```
- **BREAKING**: `assertScopesSupported()` now expects the following
hooks params object as it's last param:
  - ```
      {
       isChainIdSupported: (chainId: Hex) => boolean;
       isEvmChainIdSupported: (chainId: Hex) => boolean;
       isNonEvmScopeSupported: (scope: CaipChainId) => boolean;
       getNonEvmSupportedMethods: (scope: CaipChainId) => string[];
     }
    ```
- **BREAKING**: `bucketScopes()` now expects the following hooks params
object as it's last param:
  - ```
      {
         isEvmChainIdSupported: (chainId: Hex) => boolean;
         isEvmChainIdSupportable: (chainId: Hex) => boolean;
         isNonEvmScopeSupported: (scope: CaipChainId) => boolean;
         getNonEvmSupportedMethods: (scope: CaipChainId) => string[];
     }
    ```
- **BREAKING**: `bucketScopesBySupport()` now expects the following
hooks params object as it's last param:
  - ```
      {
         isEvmChainIdSupported: (chainId: Hex) => boolean;
         isNonEvmScopeSupported: (scope: CaipChainId) => boolean;
         getNonEvmSupportedMethods: (scope: CaipChainId) => string[];
     }
    ```
- **BREAKING**: `getSessionScopes()` now expects a hooks object as its
last param. The hooks object should have a `getNonEvmSupportedMethods`
property whose value should be a function that accepts a `CaipChainId`
and returns an array of supported methods.
- **BREAKING**: `isSupportedScopeString()` now expects the a hooks
params object as it's last param with the following properties:
  - ```
      {
         isEvmChainIdSupported: (chainId: Hex) => boolean;
         isNonEvmScopeSupported: (scope: CaipChainId) => boolean;
     }
    ```
- **BREAKING**: `isSupportedAccount()` now expects the a hooks params
object as it's last param with the following properties:
  - ```
      {
         getEvmInternalAccounts: () => { type: string; address: Hex }[];
         getNonEvmAccountAddresses: (scope: CaipChainId) => string[];
     }
    ```
- **BREAKING**: `isSupportedMethod()` now expects the a hooks params
object as it's last param with the following properties:
  - ```
      {
         getNonEvmSupportedMethods: (scope: CaipChainId) => string[];
     }
    ```
- Added `wallet_getPermissions` handler (originally migrated from
extension repo) ([#5420](https://github.com/MetaMask/core/pull/5420))
- Added `wallet_requestPermissions` handler (originally migrated from

Subject: [PATCH 0123/1148] fix: prevent `PhishingController` invalid API
 requests with -Infinity timestamp (#5385)

## Explanation

This PR fixes an edge case in the PhishingController where empty
phishingLists would trigger API requests with an invalid `-Infinity`
timestamp.

When the phishingLists array is empty and `#updateHotlist()` is called,
the code attempts to get the maximum timestamp using
`Math.max(...this.state.phishingLists.map(({ lastUpdated }) =>
lastUpdated))`. With an empty array, this results in `-Infinity`,
causing invalid API requests to `/v1/diffsSince/-Infinity`.

Added an early return check in `#updateHotlist()` when `phishingLists`
is empty to prevent making the invalid API request.

Subject: [PATCH 0125/1148] fix: add support for fetching shared announcements
 cross platforms (#5441)

## Explanation

Currently we do not support annonucements on multiple platforms (e.g.
the recent "Update" announcement did not go live due to this and we
needed to quickly split the announcement into separate ones for
portfolio and extension).

This uses the `[in]` query from contentful to allow us to fetch shared
announcements.
E.g. if there is an announcement for portfolio and extension, then we
will correctly fetch it.

Subject: [PATCH 0126/1148] Fix since-latest-release + --include-head (#5016)

The package-level `since-latest-release` script is useful when authoring
release candidate PRs for double-checking that all changes to a package
have been properly documented.

Sometimes it is useful to know all of the changes that have occurred for
a package, even those that took place on the release branch itself. For
this purpose the `--include-head` argument can be passed to the script,
e.g.:

```
yarn workspace @metamask/assets-controllers run since-latest-release --include-head -- diff
```

However, this invocation does not work and produces an error instead.

Additionally, if you pass more than one argument after the `--`, like
so:

```
yarn workspace @metamask/assets-controllers run since-latest-release --include-head -- log -p
```

then the script freezes and does not continue.

This commit addresses both of these issues.

Subject: [PATCH 0133/1148] Fix findNetworkClientIdByChainId to consider
 default endpoints (#5344)

Currently, the `findNetworkClientIdByChainId` method in
`NetworkController`, which is used in various places, mostly commonly
TransactionController and the wallet middleware, returns the network
client ID corresponding to the first listed RPC endpoint for the given
chain. This may not match users' expectations if they have chosen
another RPC endpoint as the default. This commit fixes the
implementation of `findNetworkClientIdByChainId` to match this
expectation.

Subject: [PATCH 0134/1148] perf: Simplify account iteration logic (#5445)

## Explanation

Speed up account iteration logic in `updateAccounts` by using
`KeyringController:getState` instead of getting all of the addresses
upfront and matching them to the keyring afterwards. The current
implementation is fast on extension, but really slows down on mobile
once you have a couple of accounts added. This simplified implementation
has better performance characteristics and as such performs better on
mobile.

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/accounts-controller`

- **Changed**: Speed up `updateAccounts` logic when iterating over
multiple accounts
- This requires allowlisting `KeyringController:getState` as an allowed
action for the AccountsController

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0137/1148] chore: add `RecommendedAction` to export (#5456)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

`RecommendedAction` is needed to be added to the export to be used
appropriately and tested for clients that use `scanUrl`.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

This release fixes an edge case `PhishingController` where empty
phishing lists could trigger API requests with invalid `-Infinity`
timestamps. It also exports `RecommendedAction` so that clients that use
`scanUrl` can correctly import it.

Subject: [PATCH 0139/1148] feat: updated refreshPooledStakingVaultDailyApys
 days arg default value to 365 (#5453)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?

* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This PR updates the default `days` value from `30` to `365` when
refreshing pooled staking vault apys. This means we pull one year worth
of apys by default.

Subject: [PATCH 0141/1148] fix: fix case when metadata are null (#5455)

## Explanation

This PR addresses an issue in NFT detection where the code attempts to
destructure the imageOriginal property from the NFT token's metadata
field. When metadata is null, this results in the runtime error:

`"null is not an object (evaluating '(w=void
0===w?{}:w).imageOriginal')"`

To fix the issue, the NFT detection logic has been updated to safely
handle cases where metadata is null by providing a fallback (e.g., using
an empty object or optional chaining). This prevents the error and
ensures that NFT tokens without metadata are processed without causing a
runtime exception.

Subject: [PATCH 0142/1148] fix: Override lower bound gas when gasLimit is
 defined (#5396)

## Explanation

-->

On the extension client, a strange behaviour occurrs when a dApp sends a
request with a `gasLimit` lower than the minimum 21000, but the
transaction still is confirmed with a gas of 21000.

This happens because `updateGasProperties` is called inside
`addTransaction`. `updateGasProperties` calls `updateGas` that calls
`getGas` in which if the gas property in the `txParams` is falsy, it
defaults to FIXED_GAS which is `0x5208` (21000). To fix this issue, we
can derive gas from gasLimit during normalization of transaction
parameters when the first is falsy and the second is defined.

Note that transactions correctly failed when the user tweaked the gas
prices using the appropriate modals. This is because [gas is derived
from gasLimit before new gas settings are submitted to the transaction
controller in
`updateTransactionGasFees`](https://github.com/MetaMask/metamask-extension/blob/838e4cb62765a8dafaf2f00d5e77c8593c91e845/ui/pages/confirmations/hooks/useTransactionFunctions.js#L90).

Subject: [PATCH 0147/1148] feat: add EIP-7702 signature validations (#5470)

## Explanation

Add additional validations to `signTypedData` requests to protect EOAs
that have been upgraded to a smart contract account via EIP-7702.

Specifically:

- Throw if `verifyingContract` matches any internal EOA account.
- Throw if `primaryType` is `Delegation` and `delegator` matches any
internal EOA account.
- Add dependency on `@metamask/accounts-controller`.

Subject: [PATCH 0149/1148] Feat/bridge bridge status controller env config
 (#5465)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR change the way a custom and dev urls are passed into the Bridge
and BridgeStatus controllers. Before it was through `process.env`, but
to support Mobile development, it has been changed to a config variable
in the constructor.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/bridge-controller`

- **BREAKING**: Changing Bridge API urls now occurs through the
constructor's `config` field, rather than through
`process.env.BRIDGE_CUSTOM_API_BASE_URL` and
`process.env.BRIDGE_USE_DEV_APIS`
- **BREAKING**: `getBridgeApiBaseUrl` no longer exported
- CHANGED: `BRIDGE_DEV_API_BASE_URL`, `BRIDGE_PROD_API_BASE_URL` now
exported

### `@metamask/bridge-status-controller`

- **BREAKING**: Changing Bridge API urls now occurs through the
constructor's `config` field, rather than through
`process.env.BRIDGE_CUSTOM_API_BASE_URL` and
`process.env.BRIDGE_USE_DEV_APIS`

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0150/1148] chore: export enums properly rather than as types
 (#5466)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR exports enums from `bridge-controller` as values rather than
just as types.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/bridge-controller`

- CHANGED: `AssetType, SortOrder, BridgeFlag, ActionTypes, ChainId,
BridgeFeatureFlagsKey, RequestStatus, BridgeUserAction,
BridgeBackgroundAction, FeeType` enums now exported properly rather than
just as types.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0152/1148] chore: make QuoteResponse.approval optional to
 align with response from API (#5475)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR makes `QuoteReponse.approval` optional to better align with the
Bridge API response.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/bridge-controller`

- **CHANGED**: `QuoteResponse.approval` now an optional property to
better align with the Bridge API response

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate

Subject: [PATCH 0153/1148] feat: handle primary SRP switch cases (#5478)

## Explanation

We discovered that users leverage the "forgot password" flow to switch
their primary SRPs in clients.
This is breaking auth & user storage, and this PR fixes that so that our
controller can handle use cases where the primary SRP changes to another
one.

Additional changes in clients should be made:
- Signing out the user when submitting the forgot password form on
extension

Please note that no changes in this PR introduces breaking changes.

## References

Related to: https://consensyssoftware.atlassian.net/browse/IDENTITY-60

## Changelog

### `@metamask/profile-sync-controller`

- **REMOVED**: `AuthenticationController` doesn't use the
`_snapPublicKeyCache` anymore.
- **CHANGED**: `UserStorageController` `storageKeyCache` can now hold
multiple values.
- **CHANGED**: `SDK` `getStorageKey` now takes a `message` argument for
cache navigation purposes
- **CHANGED**: `SDK` `setStorageKey` now takes an additional `message`
argument to leverage cache usages

Subject: [PATCH 0157/1148] Update workflows to use
 `MetaMask/action-checkout-and-setup` (#5474)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This updates all workflows to remove the use of `actions/checkout`,
`actions/setup-node`, `actions/cache`. The implementation here is based
on MetaMask/snaps#3214.

## References

MetaMask-planning#3925.

## Changelog

n/a, this doesn't make any changes to packages directly.

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0159/1148] Fix dependency-related constraints (#5464)

 I've noticed recently that it is impossible to add a controller
dependency just to `dependencies`; one of our existing constraints
demands that it also be added to `peerDependencies`. This is obviously
incorrect.

This commit addresses this (and other related constraints) by the
following:

- Remove `expectControllerDependenciesListedAsPeerDependencies`. This is
the faulty constraint referred to above.
- Correct `expectDependenciesNotInBothProdAndDev` (now
`expectDependenciesNotInBothProdAndDevOrPeer`) to not only ensure that a
dependency is not listed in both `dependencies` and `devDependencies`
but also both `dependencies` and `peerDependencies` (only
`devDependencies` + `peerDependencies` is allowed, as combinations go).
- Add `expectPeerDependenciesAlsoListedAsDevDependencies` constraint to
ensure that peer dependencies are also listed as dev dependencies.
- Fix `expectUpToDateWorkspaceDependenciesAndDevDependencies` to skip
validation of "production" dependencies that are also listed in peer
dependencies (this avoids conflicting constraints).
- Correct `expectConsistentDependenciesAndDevDependencies` to skip
workspace dependencies, as that is already being handled by
`expectUpToDateWorkspaceDependenciesAndDevDependencies` (this avoids
conflicting constraints).

Note that because of these changes, several controllers have also been
corrected to fit.

Subject: [PATCH 0161/1148] perf: Don't emit `:stateChange` from
 `BaseController` unnecessarily (#5480)

## Explanation

Some controllers may use conditionals inside `this.update()` and
potentially end up not modifying the `draftState` at all. In this case,
we would currently still emit `:stateChange` and listening controllers
would treat this as a state update if they don't inspect the `patches`.
This PR adjusts this logic slightly, letting us only emit events when
the state has actually changed. This reduces unnecessary events being
emitted and consumed by listening controllers.

Feedback appreciated!

Subject: [PATCH 0162/1148] feat: verify EIP-7702 contract address using
 signatures (#5472)

## Explanation

Validate all EIP-7702 contract addresses returned from feature flags
using signatures.

Specifically:

- Add optional `publicKeyEIP7702` constructor option.
- Replace `contractAddresses` with `contracts` array, where each element
contains `address` and `signature`.
- Ignore contract address if signature does not match public key.
- Signatures should be generated by signing concatenation of address and
chain ID.

### Signing Example

```sh
CHAIN_ID="7a69"
ADDRESS="8438Ad1C834623CfF278AB6829a248E37C2D7E3f"
PRIVATE_KEY="0x8ff403b85f615d1fce7b0b1334080c066ce8ea9c96f98a6ee01177f130d8ba1e"

cast wallet sign "0x$ADDRESS$CHAIN_ID" --private-key $PRIVATE_KEY

# Result
# 0x4e7307ccf8b2f5cc7c7e03ba683c0f873ad40547a37a0934ea24a3002175594e471ff6c744b99402bb5ca3f372e0cac964eb3415eea11e5173f5a83042fcaed01b
```

Subject: [PATCH 0163/1148] fix: fix invalid character error (#5490)

## Explanation
The root problem is that an uppercase hex string is being passed into
new BN(..., 10), causing it to be interpreted as a decimal value. To fix
this, avoid calling toHex on addresses that are already in 0x format.

Subject: [PATCH 0165/1148] feat: support transaction batch metrics (#5488)

## Explanation

Add additional transaction metadata to support client metrics for
transaction batch.

Specifically:

- Save `delegationAddress` for each transaction.
- Determine `transactionType` for each nested transaction.
- Add `error` to metadata in `transactionRejected` event.
- Simplify `TransactionMetadata` type.

## References

## Changelog

See `CHANGELOG.md`.

Subject: [PATCH 0166/1148] chore: explicitly pass chainIds to detectNfts
 (#5448)

## Explanation

PR updates detectNfts function to explicitly receive an array of
chainIds to detectNfts for.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/assets-controllers`

- **BREAKING**: `detectNfts` fct now accepts chainIds as a new arg
- **REMOVED**: Removed `networkClientId` as an optional param in
`detectNfts` fct in favor of new `chainIds` required arg.
- **ADDED**: `addNft` fct now accepts chainId as an additional optional
param


## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0167/1148] Split up `multichain` package into 3 packages
 (#5476)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Not everything in `@metamask/multichain` is strictly multichain-related.
We could rename this package to `@metamask/caip25`, but not everything
is CAIP-25-related, either.

To better highlight the purpose of the different parts of
`@metamask/multichain`, this commit splits it up into 3 packages:

- `@metamask/chain-agnostic-permission`: Defines an endowment type
permission designed to persist the account and chain components of a
[CAIP-25](https://github.com/ChainAgnostic/CAIPs/blob/main/CAIPs/caip-25.md)
request. This package also includes adapters and utility functions for
interfacing with this permission.
- `@metamask/eip1193-permission-middleware`: Implements the JSON-RPC
methods for managing permissions as referenced in
[EIP-2255](https://eips.ethereum.org/EIPS/eip-2255) and
[MIP-2](https://github.com/MetaMask/metamask-improvement-proposals/blob/main/MIPs/mip-2.md),
but adapted to support [chain-agnostic permission
caveats](https://npmjs.com/package/@metamask/chain-agnostic-permission).
- `@metamask/multichain-api-middleware`: JSON-RPC methods and middleware
to support the the [MetaMask Multichain
API](https://github.com/MetaMask/metamask-improvement-proposals/blob/main/MIPs/mip-5.md).

Note that the existing code in `@metamask/multichain` has not been
touched. We will deprecate and remove this package later.

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

(No updates to changelogs needed)

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0169/1148] fix(multichain-transactions-controller): filters
 out non-mainnet Solana transactions from `:accountTransactionsUpdated` events
 (#5497)

## Explanation

We were not applying the filtering for Solana mainnet transaction in the
update method `handleOnAccountTransactionsUpdated`, and this was causing
Devnet transactions appearing in the extension.

## References

* Fixes https://github.com/MetaMask/metamask-extension/issues/31072

If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

Subject: [PATCH 0174/1148] feat: refactor notification controller
 initialisation (#5504)

## Explanation

Separates out the controller constructor and initialisation. This makes
it easier to integrate with the Modular Initialisation approach in
extension and mobile.

**BREAKING** it would now require the controller to explicitly call init
after being constructed to be correctly setup. E.g.

```
const notificationServicesController = ...

// This needs to be done
notificationServicesController.init()
```

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/notification-services-controller`

- **REMOVED**: BREAKING - refactored out the
`NotificationServicesController` constructor initialisation methods. You
must explicitly call the `.init()` method to initialise controller
- **ADDED**: `init` method to initialise
`NotificationServicesController`

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0175/1148] docs: add interactive release mode documentation
 (#5467)

## Explanation
This PR updates our release process documentation to include the new
interactive mode feature, making it easier for contributors to
understand their options when creating releases.

### Documentation Changes
- Added a new section explaining the interactive release mode
- Restructured the release process documentation to clearly show two
paths:
  - Option A: Manual Release Specification
  - Option B: Interactive Mode
- Added detailed explanation of validation features including:
  - Dependency relationship checks
  - Peer dependency update requirements
  - Semantic versioning validation
- Included examples to help users understand when packages need to be
included
- Added clear navigation between the two methods

## References

Fixes https://github.com/MetaMask/core/issues/5440

## Changelog

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

 - Unlike clients, releases are not issued on a schedule; **anyone may create a release at any time**. Because of this, you may wish to review the Pull Requests tab on GitHub and ensure that no one else has a release candidate already in progress. If not, then you are free to start the process.
 - The release process is a work in progress. Further improvements to simplify the process are planned, but in the meantime, if you encounter any issues, please reach out to the Wallet Framework team.
 
-Now for the process itself:
+Now for the process itself, you have two options: using our interactive UI (recommended for most users) or manual specification.
+
+### Option A: Interactive Mode (Recommended)
+
+This option provides a visual interface to streamline the release process:
+
+1. **Start the interactive release tool.**
+
+   On the `main` branch, run:
+
+   ```
+   yarn create-release-branch -i
+   ```
+
+   This will start a local web server (default port 3000) and open a browser interface.
+
+2. **Select packages to release.**
+
+   The UI will show all packages with changes since their last release. For each package:
+
+   - Choose whether to include it in the release
+   - Select an appropriate version bump (patch, minor, or major) following SemVer rules
+   - The UI will automatically validate your selections and identify dependencies that need to be included
+
+3. **Review and resolve dependency requirements.**
+
+   The UI automatically analyzes your selections and identifies potential dependency issues that need to be addressed before proceeding. You'll need to review and resolve these issues by either:
+
+   - Including the suggested additional packages
+   - Confirming that you want to skip certain packages (if you're certain they don't need to be updated)
+
+   Common types of dependency issues you might encounter:
+
+   - **Missing dependencies**: If you're releasing Package A that depends on Package B, the UI will prompt you to include Package B
+   - **Breaking change impacts**: If you're releasing Package B with breaking changes, the UI will identify packages that have peer dependencies on Package B that need to be updated
+   - **Version incompatibilities**: The UI will flag if your selected version bumps don't follow semantic versioning rules relative to dependent packages
+
+   Unlike the manual workflow where you need to repeatedly edit a YAML file, in the interactive mode you can quickly resolve these issues by checking boxes and selecting version bumps directly in the UI.
+
+4. **Confirm your selections.**
+
+   Once you're satisfied with your package selections and version bumps, confirm them in the UI. This will:
+
+   - Create a new branch named `release/<new release version>`
+   - Update the version in each package's `package.json`
+   - Add a new section to each package's `CHANGELOG.md` for the new version
+
+5. **Review and update changelogs.**
+
+   Each selected package will have a new changelog section. Review these entries to ensure they are helpful for consumers:
+
+   - Categorize entries appropriately following the ["Keep a Changelog"](https://keepachangelog.com/en/1.0.0/) guidelines. Ensure that no changes are listed under "Uncategorized".
+   - Remove changelog entries that don't affect consumers of the package (e.g. lockfile changes or development environment changes). Exceptions may be made for changes that might be of interest despite not having an effect upon the published package (e.g. major test improvements, security improvements, improved documentation, etc.).
+   - Reword changelog entries to explain changes in terms that users of the package will understand (e.g., avoid referencing internal variables/concepts).
+   - Consolidate related changes into single entries where appropriate.
+
+   Run `yarn changelog:validate` when you're done to ensure all changelogs are correctly formatted.
+
+6. **Push and submit a pull request.**
+
+   Create a PR for the release branch so that it can be reviewed and tested.
+   Release PRs can be approved by codeowners of affected packages, so as long as the above guidelines have been followed, there is no need to reach out to the Wallet Framework team for approval.
+
+7. **Incorporate any new changes from `main`.**
+
+   If you see the "Update branch" button on your release PR, stop and look over the most recent commits made to `main`. If there are new changes to packages you are releasing, make sure they are reflected in the appropriate changelogs.
+
+8. **Merge the release PR and wait for approval.**
+
+   "Squash & Merge" the release PR when it's approved.
+
+   Merging triggers the [`publish-release` GitHub action](https://github.com/MetaMask/action-publish-release) workflow to tag the final release commit and publish the release on GitHub. Before packages are published to NPM, this action will automatically notify the [`npm-publishers`](https://github.com/orgs/MetaMask/teams/npm-publishers) team in Slack to review and approve the release.
+
+9. **Verify publication.**
+
+   Once the `npm-publishers` team has approved the release, you can click on the link in the Slack message to monitor the remainder of the process.

Subject: [PATCH 0178/1148] Expose messenger events & config for RPC failover
 (#5492)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit adds two distinct but related sets of changes to
NetworkController to further support the RPC failover work:

- It allows clients to customize RPC services — which will ultimately be
used to hit RPC endpoints — by passing an `getRpcServiceOptions` option
to the NetworkController constructor. Different RPC endpoints can have
different options, so for instance, one could specify a
`circuitBreakDuration` for all Quicknode RPC endpoints which would be
different for all Infura endpoints.
- It allows clients to tap into key events via the NetworkController
messenger. Namely, the `NetworkController:rpcEndpointUnavailable` event
will be published when too many consecutive failed requests are made to
an RPC endpoint, and `NetworkController:rpcEndpointDegraded` will be
published when an RPC endpoint responds successfully but too slowly.
(There is also a `NetworkController:rpcEndpointRequestRetried` event,
but that is mainly useful for testing.)

 ### Added
 
 - Implement circuit breaker pattern when retrying requests to Infura and custom RPC endpoints ([#5290](https://github.com/MetaMask/core/pull/5290))
-  - If the network is perceived to be down after 5 attempts, further retries will be paused for 30 seconds
-  - "Down" means the following:
+  - If the network is perceived to be unavailable after 5 attempts, further retries will be paused for 30 seconds.
+  - "Unavailable" means the following:
     - A failure to reach the network (exact error depending on platform / HTTP client)
     - The request responds with a non-JSON-parseable or non-JSON-RPC-compatible body
     - The request returns a non-200 response
 - Use exponential backoff / jitter when retrying requests to Infura and custom RPC endpoints ([#5290](https://github.com/MetaMask/core/pull/5290))
-  - As requests are retried, the delay between retries will increase exponentially (using random variance to prevent bursts)
-- Add support for automatic failover when Infura is down ([#5630](https://github.com/MetaMask/core/pull/5630))
+  - As requests are retried, the delay between retries will increase exponentially (using random variance to prevent bursts).
+- Add support for automatic failover when Infura is unavailable ([#5630](https://github.com/MetaMask/core/pull/5630))
   - An Infura RPC endpoint can now be configured with a list of failover URLs via `failoverUrls`.
   - If, after many attempts, an Infura network is perceived to be down, the list of failover URLs will be tried in turn.
-
-### Changed
-
-- **BREAKING:** `NetworkController` constructor now takes two required options, `fetch` and `btoa` ([#5290](https://github.com/MetaMask/core/pull/5290))
-  - These are passed along to functions that create the JSON-RPC middleware.
+- Add messenger action `NetworkController:rpcEndpointUnavailable` for responding to when a RPC endpoint becomes unavailable (see above) ([#5492](https://github.com/MetaMask/core/pull/5492)
+  - Also add associated type `NetworkControllerRpcEndpointUnavailableEvent`.
+- Add messenger action `NetworkController:rpcEndpointDegraded` for responding to when a RPC endpoint becomes degraded ([#5492](https://github.com/MetaMask/core/pull/5492)
+  - Also add associated type `NetworkControllerRpcEndpointDegradedEvent`.
+- Add messenger action `NetworkController:rpcEndpointRequestRetried` for responding to when a RPC endpoint is retried following a retriable error ([#5492](https://github.com/MetaMask/core/pull/5492)
+  - Also add associated type `NetworkControllerRpcEndpointRequestRetriedEvent`.
+  - This is mainly useful for tests when mocking timers.
+- Export `RpcServiceRequestable` type, which was previously named `AbstractRpcService` [#5492](https://github.com/MetaMask/core/pull/5492)
+
+### Changed
+
+- **BREAKING:** `NetworkController` constructor now takes a new required option, `getRpcServiceOptions` ([#5290](https://github.com/MetaMask/core/pull/5290), [#5492](https://github.com/MetaMask/core/pull/5492))
+  - This can be used to customize how RPC services (which eventually hit RPC endpoints) are constructed.
+  - For instance, you could set one `circuitBreakDuration` for one class of endpoints, and another `circuitBreakDuration` for another class.
+  - At minimum you will need to pass `fetch` and `btoa`.
+  - The `NetworkControllerOptions` also reflects this change.
 - **BREAKING:** Add required property `failoverUrls` to `RpcEndpoint` ([#5630](https://github.com/MetaMask/core/pull/5630))
+  - The `NetworkControllerState` and the `state` option to `NetworkController` also reflects this change
 - **BREAKING:** Add required property `failoverRpcUrls` to `NetworkClientConfiguration` ([#5630](https://github.com/MetaMask/core/pull/5630))
+  - The `configuration` property in the `AutoManagedNetworkClient` and `NetworkClient` types also reflects this change
+- **BREAKING:** The `AbstractRpcService` type now has a non-optional `endpointUrl` property ([#5492](https://github.com/MetaMask/core/pull/5492))
+  - The old version of `AbstractRpcService` is now called `RpcServiceRequestable`
 - Synchronize retry logic and error handling behavior between Infura and custom RPC endpoints ([#5290](https://github.com/MetaMask/core/pull/5290))
   - A request to a custom endpoint that returns a 418 response will no longer return a JSON-RPC response with the error "Request is being rate limited"
   - A request to a custom endpoint that returns a 429 response now returns a JSON-RPC response with the error "Request is being rate limited"

Subject: [PATCH 0179/1148] Expose error in
 NetworkController:rpcEndpointUnavailable event (#5501)

In the clients we want the ability to decide whether or not to create a
Segment error when a request to Infura fails too many times in a row.
Specifically, we want to be able to ignore connection errors, as they
may indicate that the user is offline, in which case we don't need to
fail over to Quicknode.

To accommodate this need:

- Expose the error that was encountered while making the request in the
`NetworkController:rpcEndpointUnavailable` event data.
- Export `isConnectionError` from `RpcService`.

Subject: [PATCH 0181/1148] fix: fix allNftsContract in state (#5508)

## Explanation

This PR adds an optional chainId arg in `addNftContract`.
This is sent when the source is detected since the allNftContracts in
state can be updated with a chainId that is different from the
currentChainId.
The fct addNftContract now checks if the new optional argument and
updates states accordingly.

Subject: [PATCH 0187/1148] feat: add `MegaEth Testnet` as default network
 (#5506)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
Further to Previous PR: #5495

We are adding MegaETH Testnet as default network on `Network Controller`
default state - `networkConfigurationsByChainId` with the constants and
type from the latest `controller-utils`

Which enable adding MegaETH Testnet as a default network on Mobile /
Extension

### Changes:
- Refactor the logic to separate the construction of default network
configurations to
methods`getDefaultInfuraNetworkConfigurationsByChainId` and
`getDefaultCustomNetworkConfigurationsByChainId`
- Fix `mock-network` not support a use case when the RPC endpoint come
with a path segment, e.g: 'https://carrot.megaeth.com/rpc'
- Add `MegaETH Testnet` ChainId into constants `CHAIN_IDS ` from
`transaction-controller`

### Note :
For everyone interested in testing this version in MM mobile you can use
this branch to do so :

Subject: [PATCH 0188/1148] Add Solana `accountChanged` event support (#5491)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

Changes in support of [the PR
here](https://github.com/MetaMask/metamask-extension/pull/30949) on
extension to add support for a `metamask_accountChanged` notification
via wallet_notify notification

☝️ the PR linked includes preview builds of the changes in this PR.

More context from the extension PR description:

> Add support for `metamask_accountChanged` notification via
wallet_notify
([CAIP-319](https://github.com/ChainAgnostic/CAIPs/blob/main/CAIPs/caip-319.md))
notification to enable our wallet-standard implementation to forward
account changed events via the [wallet standard change
event](https://github.com/wallet-standard/wallet-standard/blob/c6fa5fd7d58e9ea1e6762127d16585fbb56ff88a/packages/core/features/src/events.ts#L84)
>
> This is not a pattern we want to continue since the Multichain API
should not require account changing. This is a one off bespoke

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->


### @metamask/chain-agnostic-permission
- **BREAKING*:* Updated `Caip25CaveatValue` type to make
`sessionProperties` a required field instead of optional
- ADDED: Added validation for session properties in CAIP-25 caveat
- ADDED: Added `KnownSessionProperties` enum with initial
`SolanaAccountChangedNotifications` property
- ADDED: Added `isSupportedSessionProperty` function to validate session
properties
- ADDED: Added `getPermittedAccountsForScopes` helper function to get
permitted accounts for specific scopes
- ADDED: Updated merger function to properly merge session properties

### @metamask/multichain-api-middleware

Subject: [PATCH 0192/1148] feat: add multichain support to bridge-controller
 (#5486)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

The `BridgeController` currently only works with EVM networks and
addresses. In order to support Solana integration into mobile, this PR
adds the multichain compatibility updates implemented in extension.


**Specific changes**
* Add support for solana in fetchBridgeTokens util
* CAIP address and chainId support
* Solana constants, quote fetching+validation and fee calculation logic
* Replaces account used with multichain account
* Tenderly quote override for e2e testing (this enables submitting
bridge txs to a forked network so no real funds are spent)


**Notes for upgrading mobile to this version**
* Controller's allowed actions need to be updated (see `AllowedActions`
type update)
* There should be no functional differences until Solana is enabled
* When Solana is enabled, quote fetching should ✨ just work ✨

### `@metamask/bridge-controller 8.0.0`

**ADDED**
- fetching Solana tokens and bridge/swap quotes, including tx validation
and calculating Solana fees
- chainId and address formatting utilities to make client side data
compatible with the bridge-api's expected formats

**CHANGED**
- Updated BridgeController's constructor so the `fetchFn` can propagate
parameters to the underlying fetch function
- Set intervals for polling quotes based on a feature flag
- Change `bridgeFeatureFlags.chains` keys from Hex to CAIP-formatted
chainIds

Subject: [PATCH 0194/1148] fix: gas estimation for type 4 transactions (#5519)

## Explanation

The gas for type 4 transactions that include `data` to the upgraded
account can only be estimated using `eth_estimateGas` if the real
signature properties are included, otherwise the upgraded address cannot
be known since it is derived from the signature itself.

As we don't want to sign an authorisation until the user approves the
transaction, we will instead:

1. Estimate only the upgrade, with no data and a dummy signature, using
`eth_estimateGas`.
2. Estimate the data only on the resulting upgraded EOA using the
simulation API to override the account code.
3. Add the two values together, and subtract the intrinsic gas cost
(`21000`).

## References

Fixes
[#31140](https://github.com/MetaMask/metamask-extension/issues/31140)

## Changelog

See `CHANGELOG.md`.

Subject: [PATCH 0195/1148] fix: Update `txParams` gas values on `GasFeePoller`
 update (#5394)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR adds `transactionMeta.txParams` gas values based on given
`userFeeLevel` on gas fee poller updates.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

* Fixes https://github.com/MetaMask/MetaMask-planning/issues/4287

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/transaction-controller`

- **Added**: The `GasFeePoller` now updates the `maxFeePerGas` and
`maxPriorityFeePerGas` properties on the `txParams` of a transaction
when the `gasFeeEstimates` property is updated.

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0198/1148] fix: improve token rate response aborting (#5531)

## Explanation

When onboarding, we make token rates requests with 0 tokens, and then
follows up with >0 tokens (once detected).
However the old approach aborts the most recent request (that contains
new tokens), which prevents the UI from updating with rates until the
next polling cycle (or if we stop/start polling again).

My hypothesis is, since we've improved the front-end performance on
Extension and Mobile to reduce re-renders, we have optimised our polling
hooks to not be recalled (reducing the number of times we stop/start the
polling services). And because of the reduced poll restarts, we've
uncovered this bug.

Subject: [PATCH 0200/1148] feat: earn controller convert method args to
 options bags (#5537)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This PR updates a few earn-controller methods to have an options bag
argument. It also updates the `selectedAccountChange` subscription
handler to pass the `account.address` from the event payload into the
underlying methods instead of relying on `getSelectedAccount`.

### Why is this needed?
Recently, a [race
condition](https://github.com/MetaMask/accounts-planning/issues/887) was
discovered in the `accounts-controller` that causes a discrepancy
between the account data in the `selectAccountChange` event payload and
what's retrieved using `getSelectedAccount`.

The `selectAccountChange` event payload has the accurate account state
and is now passed into `refreshStakingEligibility` and
`refreshPooledStakes` to ensure they have the latest account data to
work with.

Once the issue has been resolved and the `getSelectedAccount` account
data **and** the `selectAccountChange` data are the same these overrides
won't be necessary and can likely be removed.

instead of optional positional parameters. The available options are now
`{ resetCache?: boolean, address?: string }`.
- **CHANGED**: Refactored `refreshStakingEligibility` to have a single
options bag parameter instead of optional positional parameters. The
available option is now `{ address?: string }`.
- **CHANGED**: `AccountsController:selectedAccountChange` subscription
handler now pass the `account.address` from the event payload into
`refreshStakingEligibility` and `refreshPooledStakes`. This ensure that
those underlying method have the most accurate data to work with.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

This release updates some of the method arguments for the
`earn-controller` and updates the `selectedAccountChange` subscription
handler to pass the `account?.address` from the event payload to the
underlying methods.

See changelog for further details.

Subject: [PATCH 0202/1148] fix: prevent undefined or empty currencies from
 being queried (#5458)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those

* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

`CurrencyRateController` was getting an unexpected error when the
`NetworkController.networkConfigurationsByChainId` state included any
configuration with `nativeCurrency` set as `undefined`.

The easiest way to prevent this error, as well as to avoid unnecessary
results from the API that returns currency rates, is to filter out falsy
values of `nativeCurrency` when updating currency rates.

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".

Subject: [PATCH 0203/1148] feat: support publish batch hook (#5401)

## Explanation

Support custom logic to publish a transaction batch in the
`TransactionController`.

Specifically:

- Add `PublishBatchHook`, `PublishBatchHookRequest`, and
`PublishBatchHookResult` types.
- Add optional `publishBatchHook` to `TransactionControllerOptions`.
- Add `CollectPublishHook` to record signed transactions to pass to
`PublishBatchHook`.
- Add `ExtraTransactionsPublishHook` to create a transaction batch using
the current and specified transactions.
- Populate `batchId` on each `TransactionMetadata` in the batch.
- Support existing transactions in `TransactionBatchRequest` via new
`existingTransaction` property.
- Add `useHook` property to `TransactionBatchRequest` to use only
`PublishBatchHook` rather than EIP-7702.
- Add `batchTransactions` property and `updateBatchTransactions` method.
- Automatically use `ExtraTransactionsPublishHook` if
`batchTransactions` exist on transaction.

Subject: [PATCH 0204/1148] feat: transaction batch security validation (#5526)

## Explanation

Support triggering security validation in the client while processing
transaction batches.

Specifically:

- Add `ValidateSecurityRequest` type.
- Add optional `validateSecurity` callback to `TransactionBatchRequest`
type.
- Add optional `securityAlertId` to `AddTransactionBatchRequest` type.
- Add optional `securityAlertId` to `SecurityAlertResponse` type.
- Call `validateSecurity` callback after generating EIP-7702
transaction.
- Include `delegationMock` if an EIP-7702 type 4 transaction.

## References

Relates to [
#31263](https://github.com/MetaMask/metamask-extension/issues/31263)

## Changelog

See `CHANGELOG.md`.

Subject: [PATCH 0207/1148] feat: add gas fee tokens to transaction metadata
 (#5524)

## Explanation

Retrieve the available gas fee tokens from the simulation API when
adding a transaction, and save them in the transaction metadata.

Specifically:

- Add `gasFeeTokens` to `TransactionMetadata`.
- Add `selectedGasFeeToken` to `TransactionMetadata`.
- Add additional request and response properties to types in
`utils/simulation-api.ts`.
- Update `utils/simulation.ts` to parse the gas fee tokens from the
response.

## References

Fixes [#4458](https://github.com/MetaMask/MetaMask-planning/issues/4458)

## Changelog

See `CHANGELOG.md`.

## Checklist

- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category

Subject: [PATCH 0209/1148] chore: add more chain agnostic utility functions
 for interfacing w/ caip25 permission (#5536)

## Explanation
Currently the utility/helper functions we expose to interface with and
help construct a valid caip25 permission caveat are very eth/evm centric
(i.e. `setPermittedAccounts`, `addPermittedEthChainId`,
`getPermittedEthChainIds` etc)

This PR adds some new helpers that are actually chain agnostic

## References

see @david0xd 's PR
[here](https://github.com/MetaMask/metamask-extension/pull/31203)

and my extension PR ontop of it that uses these changes:
https://github.com/MetaMask/metamask-extension/pull/31253

### `@metamask/chain-agnostic-permission`

- **CHANGED**: Renamed `caip-permission-adapter-eth-accounts.ts` to
`caip-permission-adapter-accounts.ts` to better reflect its more
generalized functionality.
- **ADDED**: New `setPermittedAccounts` function that allows setting
accounts for any CAIP namespace, not just EVM scopes.
- **ADDED**: New `addPermittedChainId` and `setPermittedChainIds`
functions for managing permitted chains across any CAIP namespace.
- **ADDED**: New `generateCaip25Caveat` function to simplify
modification of CAIP-25 permissions after UI confirmation.
- **ADDED**: New `isWalletScope` utility function to detect
wallet-related scopes.

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0210/1148] throw error in caveat validator when
 caip25:endowment permission caveat when no scopes are requested (#5548)

## Explanation

We need to add further caveat validation to throw when no scopes are
requested in either `requiredScopes` or `optionalScopes`

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->
### `@metamask/chain-agnostic-permission`

- **ADDED**: **BREAKING** Validation check in `caip25CaveatBuilder` to
prevent creating permission requests with no scopes. This ensures that
all CAIP-25 permission requests must specify at least one scope in
either `requiredScopes` or `optionalScopes`.

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0213/1148] Release/345.0.0 (#5550)

## @metamask/chain-agnostic-permission

## [0.3.0]

### Added

- Export `KnownSessionProperties` enum
([#5522](https://github.com/MetaMask/core/pull/5522))
- Add more chain agnostic utility functions for interfacing w/ caip25
permission ([#5536](https://github.com/MetaMask/core/pull/5536))
- New `setPermittedAccounts` function that allows setting accounts for
any CAIP namespace, not just EVM scopes.
- New `addPermittedChainId` and `setPermittedChainIds` functions for
managing permitted chains across any CAIP namespace.
- New `generateCaip25Caveat` function to generate a valid
`endowment:caip25` permission caveat from given accounts and chains of
any CAIP namespace.
- New `isWalletScope` utility function to detect wallet-related scopes.

### Changed

- **BREAKING:** An error is now thrown in the caveat validator when a
`caip25:endowment` permission caveat has no scopes in either
`requiredScopes` or `optionalScopes`
([#5548](https://github.com/MetaMask/core/pull/5548))

unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

These `@metamask/keyring-controller` releases are being deprecated
because they are affected by [this
issue](https://github.com/MetaMask/core/issues/5532):

Subject: [PATCH 0216/1148] fix: Remove async operation from
 `updateTransactionGasFees` (#5539)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those

* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR aims to fix an issue where `updateTransactionGasFees` updater
rejects updating draft state with following error:
`TypeError: Cannot perform 'get' on a proxy that has been revoked`

The fix is to remove that async operation because it's unnecessary to
check it again since it's been check while `addTransaction`

…ature flags

## Explanation

- Defines feature flag schema for accelerated polling parameters.
- Creates a new `getAcceleratedPollingParams` to read said feature flag
params.
- Leverages the new method inside the constructor of
`TransactionPoller`.
- Updates existing unit tests and covers `getAcceleratedPollingParams`

Subject: [PATCH 0219/1148] feat: add `MegaETH Testnet` to network-controller
 (#5527)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
Further to Previous PR: #5495

We are adding MegaETH Testnet as default network on `Network Controller`
default state - `networkConfigurationsByChainId` with the constants and
type from the latest `controller-utils`

In additional, a new constructor option `addtionalDefaultNetworks` has
introduced in `NetworkController` to
**_prevent client push the new network unintentionally_**
(such as bump up the network controller without support on the client
side)

### Changes:
- Add Constructor Option `addtionalDefaultNetworks ` to specify the
additional default networks to be included, which allows backward
compatible and only include the Network if it has ready on client side
(by developer specify)

- Refactor the logic to separate the construction of default network
configurations to
methods`getDefaultInfuraNetworkConfigurationsByChainId` and
`getDefaultCustomNetworkConfigurationsByChainId`

- Fix `mock-network` not support a use case when the RPC endpoint come
with a path segment, e.g: 'https://carrot.megaeth.com/rpc'

- Add `MegaETH Testnet` ChainId into constants `CHAIN_IDS ` from
`transaction-controller`

### Note :
For everyone interested in testing this version in MM mobile you can use
this branch to do so :

Subject: [PATCH 0220/1148] fix: remove scoped state (#5310)

## Explanation

The assets-controllers package has been updated to remove scoped state
on TokensController, TokenListController, and AccountTrackerController.
Previously, these controllers contained fields in their state that were
scoped to the current chain, while others were keyed by chain ID. The
former approach is now deprecated and has been removed in favor of
querying state by chain ID.

### Changes Implemented:
- Deprecated and removed state fields that were scoped to the current
chain.
- Ensured all clients use per-chain variants of these state fields.
- Removed logic in controllers that updated the deprecated fields.

### Removed State Fields and Their Replacements:
- **TokensController:**
  - Removed: `tokens`, `ignoredTokens`, `detectedTokens`
  - Use instead: `allTokens`, `allIgnoredTokens`, `allDetectedTokens`
- **AccountTrackerController:**
  - Removed: `accounts`
  - Use instead: `accountsByChain`
- **TokenListController:**
  - Removed: `tokenList`
  - Use instead: `tokensChainsCache`

changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".

### `@metamask/assets-controllers`

- **REMOVED**: Deprecated state fields scoped to the current chain.
- **CHANGED**: Updated `TokensController`, `TokenListController`, and
`AccountTrackerController` to use per-chain state variants.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0221/1148] feat: add `removeNetwork` to
 `multichain-network-controller` (#5516)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR changes the way network removal is handled. It can now proxy requests to the network-controller

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

-->

* Fixes https://github.com/MetaMask/accounts-planning/issues/868

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/multichain-network-controller`

- **ADDED**: `removeNetwork` method. The new added method handles two
cases,
- EVM: The request is re-directed to the `network-controller` if certain
conditions are met
  - Non-EVM: It is not possible to remove non-EVM network

### `@metamask/network-controller`

- **ADDED**: New action to get the selected chain ID

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0222/1148] feat: Add `RandomisedEstimationsGasFeeFlow` to gas
 fee flows (#5511)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR aims to add `RandomisedEstimationsGasFeeFlow` to gas fee flows
in `TransactionController`.

Depending on the remote feature flags, `RandomisedEstimationsGasFeeFlow`
randomises the last digits of given estimations. To see exact
randomisation it is happening `randomiseDecimalValueAndConvertToHex`
function in the `RandomisedEstimationsGasFeeFlow.ts` file. Also in case
of any error this gas fee flow will default to `DefaultGasFeeFlow`.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

### `@metamask/transaction-controller`

- **ADDED**: Adds `RandomisedEstimationsGasFeeFlow` to gas fee flows in
`TransactionController`
- Added flow only will be activated if `chainId` is defined in feature
flags.

 ## [Unreleased]
 
+### Added
+
+- Adds `RandomisedEstimationsGasFeeFlow` to gas fee flows in `TransactionController` ([#5511](https://github.com/MetaMask/core/pull/5511))
+  - Added flow only will be activated if chainId is defined in feature flags.
+
 ### Fixed
 
 - Fix simulation of type-4 transactions ([#5552](https://github.com/MetaMask/core/pull/5552))

Subject: [PATCH 0223/1148] fix: validation of EIP-7702 contract signatures
 with odd-length chain ID (#5563)

## Explanation

Pad chain ID with leading zero if odd-length in order to prevent
signature validation from silently failing.

## References

Relates to
[#31388](https://github.com/MetaMask/metamask-extension/issues/31388)

## Changelog

See `CHANGELOG.md`.

Subject: [PATCH 0224/1148] fix: incoming transactions can't display in active
 tab (#5487)

## Explanation
**Issue**:
The incoming transactions can't display in active tab.

**Root cause**:
1. When the transfer from account **A** to **B** is completed, the
transfer's information({hash:"123abc...", from: "account A", type:
"**simpleSend**"}) will be cached in local storage.
2. Then switch to account B, the account API returns account B's related
transactions include {hash:"123abc...", from: "account A", type:
"**incoming**"}
3. According to current logic, transactions with the same **hash** and
**from** will be filtered out, so the incoming transaction from A to B
can't display in account B's active tab

**Solution**:
Add a  transaction filter condition with the same type attribute.

Subject: [PATCH 0225/1148] Document new process for updating changelogs
 (#5111)

Currently, we ask that when contributors submit a pull request, they
fill out a Changelog section in the description which lists all of the
consumer-facing changes they've made. This section is ultimately used
when creating a new release to assist with populating `CHANGELOG.md`
files.

However, this process is difficult to follow in practice because it
forces release authors to do work on behalf of other engineers. The
people that know how to describe changes best are those that made the
change, so they should be reponsible for updating changelogs.

With this commit, we now direct contributors to update changelog files
directly as they make changes instead of placing them in the Changelog
section of the PR description.

+## Updating changelogs
+
+Each package in this repo has a file called `CHANGELOG.md` which is used to record consumer-facing changes that have been published over time. This file is useful for other engineers who are upgrading to new versions of packages so that they know how to use new features they are expecting, they know when bugs have been addressed, and they understand how to adapt to breaking changes (if any). All changelogs follow the ["Keep a Changelog"](https://keepachangelog.com/) specification (enforced by `@metamask/auto-changelog`).
+
+As you make changes to packages, make sure to update their changelogs in the same branch.
+
+We will offer more guidance here in the future, but in general:
+
+- Place new entries under the "Unreleased" section.
+- Place changes into categories. Consult the ["Keep a Changelog"](https://keepachangelog.com/en/1.1.0/#how) specification for the list.
+- Highlight breaking changes by prefixing them with `**BREAKING:**`.
+- Omit non-consumer facing changes from the changelog.
+- Do not simply reuse the commit message, but describe exact changes to the API or usable surface area of the project.
+- Use a list nested under a changelog entry to enumerate more details about a change if need be.
+- Include links to pull request(s) that introduced each change. (Most likely, this is the very same pull request in which you are updating the changelog.)
+- Combine like changes from multiple pull requests into a single changelog entry if necessary.
+- Split disparate changes from the same pull request into multiple entries if necessary.
+- Omit reverted changes from the changelog.

 ## Creating pull requests
 
-When submitting a pull request for this repo, take some a bit of extra time to fill out its description. Use the provided template as a guide, paying particular attention to two sections:
-
-- **Explanation**: This section is targeted toward maintainers and is intended for you to explain the purpose and scope of your changes and share knowledge that they might not be able to see from reading the PR alone. Some questions you should seek to answer are:
-  - What is the motivator for these changes? What need are the changes satisfying? Is there a ticket you can share or can you provide some more context for people who might not be familiar with the domain?
-  - Are there any changes in particular whose purpose might not be obvious or whose implementation might be difficult to decipher? How do they work?
-  - If your primary goal was to update one package but you found you had to update another one along the way, why did you do so?
-  - If you had to upgrade a dependency, why did you do so?
-- **Changelog:** This section is targeted toward consumers — internal developers of the extension or mobile app in addition to external dapp developers — and is intended to be a list of your changes from the perspective of each package in the monorepo. Questions you should seek to answer are:
-  - Which packages are being updated?
-  - What are the _exact_ changes to the API (types, interfaces, functions, methods) that are being changed?
-  - What are the anticipated effects to whichever platform might want to make use of these changes?
-  - If there are breaking changes to the API, what do consumers need to do in order to adapt to those changes upon upgrading to them?

This section is intended for you to explain the purpose and scope of your changes and share knowledge that other engineers might not be able to see from reading the PR alone. Some questions you should seek to answer are:
+
+- What is the motivator for these changes? What need are the changes satisfying? Is there a ticket you can share or can you provide some more context for people who might not be familiar with the domain?
+- Are there any changes in particular whose purpose might not be obvious or whose implementation might be difficult to decipher? How do they work?
+- If your primary goal was to update one package but you found you had to update another one along the way, why did you do so?
+- If you had to upgrade a dependency, why did you do so?

Subject: [PATCH 0228/1148] chore: remove `goerli` and `linea goerli` from
 `network-controller` as default network (#5560)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR is not to deprecated `goerli` and `linea goerli` , but just
remove `goerli` and `linea goerli` from `network-controller` as default
network, which will not impact to the reference of those network
constants / type

Hence the mobile / extension no longer require to using patching or
hardcode to remove the network for new installed user

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/network-controller`

- **CHANGED**: Remove `goerli` and `linea goerli` network as default
network

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0230/1148] feat: support transactions from account snaps that
 should not be published (#5045)

## Explanation

Relates to [this extension
PR](https://github.com/MetaMask/metamask-extension/pull/28691)


## References

[Institutional Snap
RAPID](https://docs.google.com/document/d/16vKfRpbJrdtTMKaCU7wS61ffaEUe8vLZgZbxdLF39MY/edit?tab=t.0#heading=h.r7r3tthf4lsf)

> We then use the existing beforePublish hook in metamask-controller to
read this option and tell the transaction controller not to publish
based on it. As a side effect, this hook also sets the hash of the
transaction and marks it as submitted.


## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/transaction-controller`

- **CHANGED**: Removed coupling of "Update custodial transactions" and
MMI
- **CHANGED**: Changes signature of hooks to return promises
- **ADDED**: `updateCustodialTransaction` now allows changing more
properties

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0232/1148] fix(accounts-controller): do not fire events during
 `update` blocks (#5555)

## Explanation

Events should be fired after making a state update. Otherwise we could
end up with race conditions like some other component react to
`AccountsController:accountAdded` and try to call
`getAccount(account.id)`, it might not the same value compared to the
`account` being passed during the event (since the state update has not
been persisted yet).

This PR now moves all events firing after the state update.

It also includes a small refactor of the `KeyringController:stateChange`
handler (which made the new events firing logic, a bit easier).

Test E2E PR:
- https://github.com/MetaMask/metamask-extension/pull/31393 (CI is
passing)

Subject: [PATCH 0233/1148] feat: validate chain ID matches network client ID
 (#5569)

## Explanation

Mark `chainId` as deprecated in `TransactionParams`.

Validate, if provided, that `chainId` matches the `networkClientId` when
calling `addTransaction`.

Subject: [PATCH 0236/1148] NetworkController: Make failover URLs optional
 (#5561)

There are two new non-optional properties that were added in a previous
commit:

- `failoverUrls` in `RpcEndpoint` (which is used in NetworkController
state)
- `failoverRpcUrls` in `NetworkClientConfiguration` (which is exposed
via the network client)

Making these properties non-optional makes sense to avoid `undefined`,
however, this is requiring clients that wish to upgrade to implement a
migration to ensure that state is valid along with many other changes to
test files and such which expect state to be a certain shape. We would
rather avoid this right now due to some other changes to
`network-controller` that we need to adapt to, so to make the
maintenance burden lighter, we are changing these to optional. We will
change them back to non-optional in another commit.

Subject: [PATCH 0237/1148] feat: add chain specific gas estimation fallbacks
 using remote feature flags (#5556)

## Explanation

This PR updates the estimated gas fee fallback mechanism to be
configurable per chain. If a chain-specific value is not set, it will
default to the previous multiplier. Additionally, both the fallback
default and per chain are now configurable via LaunchDarkly, allowing
multiplier and fixed values for more flexibility in determining gas fees
based on the chain's requirements.

Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?

* Related to #67890
-->
* Fixes https://github.com/MetaMask/MetaMask-planning/issues/4498

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for

 ### Changed
 
-- Updated `TokensController`, `TokenListController`, and `AccountTrackerController` to use per-chain state variants. ([#5310](https://github.com/MetaMask/core/pull/5310))
+- Update `TokensController`, `TokenListController`, and `AccountTrackerController` to use per-chain state variants ([#5310](https://github.com/MetaMask/core/pull/5310))
+- Bump `@metamask/keyring-api` to `^17.4.0` ([#5565](https://github.com/MetaMask/core/pull/5565))
+- Bump `@metamask/controller-utils` to `^11.7.0` ([#5583](https://github.com/MetaMask/core/pull/5583))
+  - Via this upgrade, `updateExchangeRates` now supports the MegaETH testnet
 
 ### Removed
 
 - **BREAKING:** Remove deprecated state fields scoped to the current chain ([#5310](https://github.com/MetaMask/core/pull/5310))
-  - This change removes the following state fields:
-    - `TokensController:state`
+  - This change removes the following state fields from the following controllers:
+    - `TokensControllerState`
       - `detectedTokens` (replaced by `detectedTokensByChainId`)
       - `ignoredTokens` (replaced by `ignoredTokensByChainId`)
       - `tokens` (replaced by `tokensByChainId`)
-    - `TokenListController:state`
+    - `TokenListControllerState`
       - `tokenList` (replaced by `tokensChainsCache`)
-    - `AccountTrackerController:state`
+    - `AccountTrackerControllerState`
       - `accounts` (replaced by `accountsByChainId`)
+  - This will require a migration in the clients to remove them from state in order to prevent unnecessary Sentry errors when updating controller state.
+
+### Fixed
+
+- Update token rate request key to handle when new tokens are detected inside the `TokenRatesController` ([#5531](https://github.com/MetaMask/core/pull/5311)))
+- Update `CurrencyRateController` to prevent undefined or empty currencies from being queried ([#5458](https://github.com/MetaMask/core/pull/5458)))

 ### Added
 
 - Re-export `ConstantBackoff` and `ExponentialBackoff` from `cockatiel` ([#5492](https://github.com/MetaMask/core/pull/5492))
   - These can be used to customize service policies
 - Add optional `backoff` option to `createServicePolicy` ([#5492](https://github.com/MetaMask/core/pull/5492))
   - This is mainly useful in tests to force the backoff strategy to be constant rather than exponential
+- Add `BUILT_IN_CUSTOM_NETWORKS_RPC`, which includes MegaETH ([#5495](https://github.com/MetaMask/core/pull/5495))
+- Add `CustomNetworkType` quasi-enum and type, which includes MegaETH ([#5495](https://github.com/MetaMask/core/pull/5495))
+- Add `BuiltInNetworkType` type union, which encompasses all Infura and custom network types ([#5495](https://github.com/MetaMask/core/pull/5495))
+
+### Changed
+
+- Add MegaETH Testnet to various constants, enums, and types ([#5495](https://github.com/MetaMask/core/pull/5495))
+  - Add `MEGAETH_TESTNET` to `TESTNET_TICKER_SYMBOLS`
+  - Add `megaeth-testnet` to `BUILT_IN_NETWORKS`
+  - Add `MegaETHTestnet` to `BuiltInNetworkName` enum
+  - Add `megaeth-testnet` to `ChainId` type
+  - Add `MegaETHTestnet` to `NetworksTicker` enum
+  - Add `MegaETHTestnet` to `BlockExplorerUrl` quasi-enum
+  - Add `MegaETHTestnet` to `NetworkNickname` quasi-enum
+- `CHAIN_ID_TO_ETHERS_NETWORK_NAME_MAP` is now typed as `Record<string, BuiltInNetworkName>` rather than `Record<ChainId, BuiltInNetworkName>` ([#5495](https://github.com/MetaMask/core/pull/5495))
+- `NetworkType` quasi-enum now includes all keys/values from `CustomNetworkType` ([#5495](https://github.com/MetaMask/core/pull/5495))

+### Added
+
+- Add optional `additionalDefaultNetworks` option to `NetworkController` constructor ([#5527](https://github.com/MetaMask/core/pull/5527))
+  - This can be used to customize which custom networks the default `networkConfigurationsByChainId` includes.
+- Add `getSelectedChainId` method to `NetworkController` ([#5516](https://github.com/MetaMask/core/pull/5516))
+  - This is also callable via the messenger.
+- Add `DEPRECATED_NETWORKS` constant ([#5560](https://github.com/MetaMask/core/pull/5560))
+
 ### Changed
 
+- Remove Goerli and Linea Goerli from set of default networks ([#5560](https://github.com/MetaMask/core/pull/5560))
+  - Note that if you do not pass any initial state to NetworkController, this means that `0x5` and `0xe704` will no longer be keys in `networkConfigurationsByChainId`.
+  - We are not counting this as a breaking change because we don't make any guarantees about what keys are present in `networkConfigurationsByChainId` at runtime — only that they must be valid chain IDs.
+  - If you want more of a guarantee, you are recommended to persist the NetworkController state and then pass it back through as initial state.
 - Update `RpcEndpoint` so that `failoverUrls` is optional ([#5561](https://github.com/MetaMask/core/pull/5561))
-  - This property was introduced in 23.0.0 as a breaking change, but this change makes it non-breaking

Subject: [PATCH 0243/1148] fix: skip origin validation for batch transactions
 (#5586)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This PR aims to pass the `origin` for batch transactions. Additionally,
skip the origin validation based on the `batch` type.

Subject: [PATCH 0244/1148] Stop throwing an error if `verifyingContract` field
 in EIP712 payloads is undefined or not a string (#5595)

## Explanation
It seems we've broken some dapps that rely on EIP712 /
`eth_signTypedData_v4` signatures which don't include
`verifyingContract` as part of their payload.

This PR updates the `EarnController` to refresh a user's pooled-staking
data when a staking transaction is confirmed. Non-staking transaction
types are ignored.

- Added a new subscription to the
`TransactionController:transactionConfirmed` event has been added.
- Added `@metamask/transaction-controller` has been added as a dev
dependency.
- Added related tests.

Subject: [PATCH 0251/1148] fix: Rename `enableTxParamsGasFeeUpdates` to
 `isAutomaticGasFeeUpdateEnabled` and also callback (#5602)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR aims to rename `enableTxParamsGasFeeUpdates` to
`isAutomaticGasFeeUpdateEnabled` and make it a callback function instead
of a boolean.
This callback is invoked before performing `txParams` gas fee updates.
The update will proceed only if the callback returns a truthy value.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

 ## [Unreleased]
 
+### Added
+
+- Add types for `isAtomicBatchSupported` method ([#5600](https://github.com/MetaMask/core/pull/5600))
+  - `IsAtomicBatchSupportedRequest`
+  - `IsAtomicBatchSupportedResult`
+  - `IsAtomicBatchSupportedResultEntry`
+
 ### Changed
 
+- **BREAKING:** Update signature of `isAtomicBatchSupported` method ([#5600](https://github.com/MetaMask/core/pull/5600))
+  - Replace `address` argument with `request` object containing `address` and optional `chainIds`.
+  - Return array of `IsAtomicBatchSupportedResultEntry` objects.
 - Skip `origin` validation for `batch` transaction type ([#5586](https://github.com/MetaMask/core/pull/5586))
 - **BREAKING:** `enableTxParamsGasFeeUpdates` is renamed to `isAutomaticGasFeeUpdateEnabled` now expects a callback function instead of a boolean.
   - This callback is invoked before performing `txParams` gas fee updates. The update will proceed only if the callback returns a truthy value.

Subject: [PATCH 0253/1148] feat: support external sign transactions (#5604)

## Explanation

Support transactions that are signed externally, such as delegations,
using a new `isExternalSign` property that disables nonce generation and
signing via the `KeyringController`.

Subject: [PATCH 0254/1148] refactor(accounts-controller): use type-cast
 instead of `@ts-expect-error` (#5568)

## Explanation

Commenting out the `@ts-expect-error` was not very reliable sometimes
(it works everytime on the CI, but not everytime when compiling/running
tests locally). We sometimes have to uncomment the directive to run the
tests (which is a bit annoying and force you to have some "unstaged
change" in `git`).

The type-cast does get rid of the compile-error with `WritableDraft`
while still providing the same "object signature" and has 0 impact at
runtime either. So this is safe.

Subject: [PATCH 0256/1148] fix: Update origin in Snap requests (#5616)

## Explanation

We are making a change to the SnapController to more strictly validate
the `origin` parameter. This disallows empty string which was previously
allowed. This PR updates the `profile-sync-controller` to comply with
these new requirements.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0260/1148] Fix unmocked block tracker warning in
 NetworkController tests (#5289)

When running one of the tests for NetworkController, we were seeing a
warning in the test output indicating that a request from the block
tracker was not properly mocked. This commit adds that mock so the
warning goes away.

Subject: [PATCH 0262/1148] fix: cache incoming transaction timestamps (#5582)

## Explanation

If `queryEntireHistory` is `false`, query incoming transactions from the
last 24 hours.

If no cursor is returned, cache the `startTimestamp` and use that in
subsequent queries until a cursor is available.

Subject: [PATCH 0264/1148] feat: remove `isAccountSyncingEnabled` `env`
 property from `UserStorageController` constructor (#5629)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

Since account syncing is now enabled by default in both clients, we are
removing the possibility to control `isAccountSyncingEnabled` from the
`UserStorageController` contructor `env` property.

In a subsequent PR, we'll introduce a new `isAccountSyncingEnabled`
state property, and expose a way to toggle it from the clients. For now,
all clients dispatch account syncing depending on if
`isProfileSyncingEnabled` is `true`, so we can do this change in another
PR without risking to break anything.
The UTs flagged with `it.todo` in the PR will then be updated using this
new state property.

This change is **BREAKING**, and the clients need to remove the
`isAccountSyncingEnabled` property from `UserStorageController` `env`
when instantiating the controller.

Subject: [PATCH 0267/1148] feat: add backup and sync granular feature control
 (#5636)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR adds a new public method, `setIsBackupAndSyncFeatureEnabled` to
`UserStorageController`
This replaces `enableProfileSyncing` and `disableProfileSyncing` and
will be used as the main method to enable and disable backup and sync
features from now on. As a result, this is a **BREAKING** change.

This PR also adds the `isAccountSyncingEnabled` state property to
`UserStorageController`. This defaults to `true`.

## References

Fixes: https://consensyssoftware.atlassian.net/browse/IDENTITY-81
Extension test drive PR (CI ✅):
https://github.com/MetaMask/metamask-extension/pull/31939

Subject: [PATCH 0269/1148] fix: update active network based on account's
 namespace (#5642)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR introduces two small changes,

1. Remove object de-structuring on controller constructor
2. Fix the condition to update the active network based on the account
event

Subject: [PATCH 0270/1148] feat: remove unused action handlers (#5638)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR removes unused `UserStorageController` action handlers:
`setIsBackupAndSyncFeatureEnabled`,
`syncInternalAccountsWithUserStorage` and
`saveInternalAccountToUserStorage`, as they should not be callable
through the messaging system.

This is a **BREAKING** change, although no other Controller should use
them at the moment.

Subject: [PATCH 0272/1148] refactor: add `EncryptionKey` type parameter to
 `ExportableKeyEncryptor` (#5395)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
The `ExportableKeyEncryptor` type used to identify encryptor that
support exported keys has been made generic, with a type parameter
`EncryptionKey` to let the consumer define the type of key that will be
used for encryption (e.g. `CryptoKey`). The type parameter defaults to
`unknown`, making this non-breaking.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

### `@metamask/keyring-controller`

- **CHANGED**: The `ExportableKeyEncryptor` is now a generic type with a
type parameter `EncryptionKey`
([#5395](https://github.com/MetaMask/core/pull/5395))
  - The type parameter defaults to `unknown`

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0274/1148] feat: use feature flags for gas estimation buffers 
 (#5637)

## Explanation

Use feature flags to configure the gas estimation buffers, including
support for specific chain and type-4 buffers.

```js
[FeatureFlag.GasBuffer]?: {
    /** Fallback buffer for all chains and transactions. */
    default?: number;

    /**
     * Buffer for included network RPCs only and not those added by user.
     * Takes priority over `default`.
     */
    included?: number;

    /** Buffers for specific chains. */
    perChainConfig?: {
      [chainId: Hex]: {
        /**
         * Buffer for the chain for all transactions.
         * Takes priority over non-chain `included`.
         */
        base?: number;

        /**
         * Buffer if network RPC is included and not added by user.
         * Takes priority over `base`.
         */
        included?: number;

        /**
         * Buffer for the chain for EIP-7702 / type 4 transactions only.
         * Only if `data` included and `to` matches `from`.
         * Takes priority over `included` and `base`.
         */
        eip7702?: number;
      };
    };
  };
```

Subject: [PATCH 0277/1148] fix: confusing error message when using wrong
 password (#5627)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
When calling `submitPassword` with the wrong password, a confusing error
is shown instead of `Incorrect password`. This is due to the recently
added metadata length check in `#restoreSerializedKeyrings`, which
doesn't match the correct behavior when `isUnlocked = true`.

We can move the metadata length check to `#unlockKeyrings`, so that it
will be skipped everytime the controller is locked

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->
* Related to https://github.com/MetaMask/metamask-extension/issues/31436

Subject: [PATCH 0280/1148] feat: adds support for blue-chip endpoint (#5588)

Currently the token-search doesn't support the Portfolio APIs `blue-chip` endpoint. We need to add support for it, because the mm-mobile requires it.

Fixes MMPD-1575.

Subject: [PATCH 0284/1148] feat: add delegation controller (#5592)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

Creates a new controller as a centralized place for signing and storing
delegations.

We have decided to not include the `@metamask/delegation-toolkit` (nor
`viem`) as a dependency, since we don't need to rely on much from there
in order to operate (a couple of type definitions, mostly).
Instead, we rely on the requester to provide information about the
delegation environment (e.g., `verifyingContract` address). Also, in
order to avoid bringing `viem` as a dependency, we require that the
requester provides the delegation hash when storing delegation, so we
don't need to calculate it.

unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?

+- Add `reselect` as a dependency at `^5.1.1` ([#5614](https://github.com/MetaMask/core/pull/5614))
+- **BREAKING:** assetExchangeRates added to BridgeController state to support tokens which are not supported by assets controllers ([#5614](https://github.com/MetaMask/core/pull/5614))
+- selectExchangeRateByChainIdAndAddress selector added, which looks up exchange rates from assets and bridge controller states ([#5614](https://github.com/MetaMask/core/pull/5614))
+- selectBridgeQuotes selector added, which returns sorted quotes including their metadata ([#5614](https://github.com/MetaMask/core/pull/5614))
+- selectIsQuoteExpired selector added, which returns whether quotes are expired or stale ([#5614](https://github.com/MetaMask/core/pull/5614))
+
 ### Changed
 
+- **BREAKING:** Change TokenAmountValues key types from BigNumber to string ([#5614](https://github.com/MetaMask/core/pull/5614))
+- **BREAKING:** Assets controller getState actions have been added to `AllowedActions` so clients will need to include `TokenRatesController:getState`,`MultichainAssetsRatesController:getState` and `CurrencyRateController:getState` in controller initializations ([#5614](https://github.com/MetaMask/core/pull/5614))
+- Make srcAsset and destAsset optional in Step type to be optional ([#5614](https://github.com/MetaMask/core/pull/5614))
+- Make QuoteResponse trade generic to support Solana quotes which have string trade data ([#5614](https://github.com/MetaMask/core/pull/5614))
 - Bump `@metamask/multichain-network-controller` peer dependency to `^0.4.0` ([#5649](https://github.com/MetaMask/core/pull/5649))

Subject: [PATCH 0288/1148] feat: added DeFiPositionsController (#5400)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR adds a new controller that will be used to fetch DeFi positions
for both extension and mobile.

It does so on network state or account change.

Draft PR for extension:

 - [**CollectiblesController**](src/CollectiblesController.ts) tracks ERC-721 and ERC-1155 tokens assigned to the currently selected address, using OpenSea to retrieve token information.
 - [**CurrencyRateController**](src/CurrencyRateController.ts) keeps a periodically updated value of the exchange rate from the currently selected "native" currency to another (handling testnet tokens specially).
+- [**DeFiPositionsController**](src/DeFiPositionsController/DeFiPositionsController.ts.ts) keeps a periodically updated value of the DeFi positions for the owner EVM addresses.
 - [**RatesController**](src/RatesController/RatesController.ts) keeps a periodically updated value for the exchange rates for different cryptocurrencies. The difference between the `RatesController` and `CurrencyRateController` is that the second one is coupled to the `NetworksController` and is EVM specific, whilst the first one can handle different blockchain currencies like BTC and SOL.
 - [**TokenBalancesController**](src/TokenBalancesController.ts) keeps a periodically updated set of balances for the current set of ERC-20 tokens.
 - [**TokenDetectionController**](src/TokenDetectionController.ts) keeps a periodically updated list of ERC-20 tokens assigned to the currently selected address.

Subject: [PATCH 0289/1148] chore: remove branch filtering from changelog check
 workflow (#5651)

## Explanation

Removes the 'branches' filter from the pull_request trigger for the
changelog check workflow.

This allows the workflow to run on pull requests targeting any branch,
including release branches, ensuring changelog entries (including
dependency bumps) are validated consistently across all PR types.

…tor controller to not rely on active network

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?

* If you had to upgrade a dependency, why did you do so?
-->
Temporary workaround to hardcode Ethereum mainnet (`1`) as the selected
chainId. We cannot rely on the active network state from the
`NetworkController` since we need to be able to fetch data for one or
more chains regardless of the active network.

There should be no regressions since Ethereum mainnet is the only
supported `chainId` for pooled-staking anyway.

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so

your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?

* If your primary goal was to update one package but you found you had

* If you had to upgrade a dependency, why did you do so?
-->

Use the protocol display name value from the API instead of building it
internally.

If you're making any consumer-facing changes, list those changes here as
if you were updating a changelog, using the template below as a guide.

(CATEGORY is one of BREAKING, ADDED, CHANGED, DEPRECATED, REMOVED, or
FIXED. For security-related issues, follow the Security Advisory
process.)

Please take care to name the exact pieces of the API you've added or
changed (e.g. types, interfaces, functions, or methods).

If there are any breaking changes, make sure to offer a solution for
consumers to follow once they upgrade to the changes.

Finally, if you're only making changes to development scripts or tests,
you may replace the template below with "None".
-->

They are internal changes, no need to add them to changelog.

Subject: [PATCH 0293/1148] feat: solana tx submission in
 @metamask/bridge-status-controller (#5634)

## Explanation

Extension integration PR:
https://github.com/MetaMask/metamask-extension/pull/31907

This adds a `submitTx` method to the bridge-status-controller that
submits a Solana tx to the Keyring/snap controller then starts polling
for transaction status

To use this in mobile/extension
- replace the confirmation and status polling calls with `submitTx`
- the new method needs to be bound
- the controller init needs to be updated with snap permissions (see
[extension
example](https://github.com/MetaMask/metamask-extension/pull/31907/files#diff-6fbff2cfe97ac01b77296ef2122c7e0a5b3ff6a84b584b4d1a87482f35eea3d6))
- this change depends on type updates included in
[bridge-controller](https://github.com/MetaMask/core/pull/5614)

Subject: [PATCH 0294/1148] feat: fetch networks with transaction activity by
 accounts (#5551)

## Explanation

Currently, our client manually adds networks and checks user activity
one network at a time. This is inefficient and doesn't scale well.

This PR introduces a more efficient approach by:
1. Adding a new API integration that fetches active networks for
multiple accounts in a single request
2. Managing network activity state through the controller
3. Adding type-safe methods to handle both EVM and non-EVM accounts
4. Extracting network fetching logic into a dedicated service layer

Key additions:
- `getNetworksWithTransactionActivityByAccounts`: Fetches active
networks for accounts
- `MultichainNetworkService`: New service layer handling network
activity fetching
- Enhanced state management for network configurations and activity
- Improved error handling and fallback mechanisms

The new implementation:
- Reduces API calls through batch fetching
- Improves separation of concerns with dedicated service layer
- Enhances type safety and error handling
- Provides better state management with fallbacks

Subject: [PATCH 0301/1148] chore: add optional approvalTxId to
 BridgeHistoryItem (#5670)

## Explanation

### Problem

Currently we associate bridge approvals with the corresponding
transaction by calling `updateTransaction` after submission. This
overwrites the existing transaction meta and can potentially put
transactions in a bad state (see
[thread](https://consensys.slack.com/archives/C08E59AS3T9/p1740696296183909?thread_ts=1740695171.154799&cid=C08E59AS3T9))

### Solution
If a quote involves an approval, add the txId to the bridgeHistoryItem.
This enables clients to lookup quote data by the approvalTxId and
display quote data. This removes the need for calling
`updateTransaction` to append metadata to bridge and approval
transactions, and also reduces quote data duplicated in state

### Draft PR for extension
This commit includes a selector that performs a lookup by approvalTxId,
then uses the data to populate the activity details:

+### Fixed
+
+- Add optional `approvalTxId` key to BridgeHistoryItem to associate an approval with a bridge transaction ([5670](https://github.com/MetaMask/core/pull/5670))
+  - Fixes issue where calling `updateTransaction` to associate approvals with bridge transactions could overwrite transaction metadata and put transactions in a bad state
+  - Instead, store the approval transaction ID in the bridge history item, enabling clients to look up bridge transactions by their approval ID without modifying transaction metadata
+

Subject: [PATCH 0303/1148] Refactor: migrate wallet_createSession handler
 (#5647)

## Explanation

[Original
ticket](https://github.com/MetaMask/MetaMask-planning/issues/4127)

Part of the scope of
https://github.com/MetaMask/MetaMask-planning/issues/4130 is having the
currently existing multichain handlers for:

`wallet_createSession`
`wallet_revokeSession`
`wallet_getSession`
`wallet_invokeMethod`

Available in the mobile codebase.

This raises an issue, where if future changes are required in any of
these handlers, those would need to be done on both extension and mobile
codebases, instead of having one single source of truth. Therefore, as
part of this https://github.com/MetaMask/MetaMask-planning/issues/4130,
we could extract the existing handlers on extension repo over to core
and create a release for that so they can be imported in whichever code
base needs them.

Thankfully, most of these already live in core monorepo, so we will only
need to extract `wallet_createSession` handler.

As part of this work, create another refactor ticket for these to later
be imported on extension repo and removed from that codebase altogether
(not urgent at the moment).

Subject: [PATCH 0306/1148] fix(multichain-network): temporarily restrict
 network activity to EVM (#5677)

## Explanation

This PR temporarily restricts the
`getNetworksWithTransactionActivityByAccounts` method to EVM networks
only. This change is necessary because:

1. The non-EVM network endpoint support is still being completed and
needs additional work
2. We want to ensure reliable functionality for EVM networks while
non-EVM support is being finalized
3. This allows us to maintain stable service for our primary use case
(EVM networks) while API platform team completes the full multi-chain
implementation

### Technical Details
- Added a filter to exclude non-EVM accounts from network activity
checks
- Updated the `CHANGELOG` to reflect this temporary limitation
- This is an interim solution that will be reverted once non-EVM
endpoint support is complete (expected in the coming weeks)

## References

- Related to
[#4469](https://github.com/MetaMask/MetaMask-planning/issues/4469)
- Builds upon [#5551](https://github.com/MetaMask/core/pull/5551)

## Changelog

### `@metamask/multichain-network-controller`

- **CHANGED**: `getNetworksWithTransactionActivityByAccounts` to only
support EVM networks only for now

## Checklist

- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs

Subject: [PATCH 0308/1148] Feat/bulk scan phishing controller (#5682)

# Add bulk URL phishing scanning capability to PhishingController

## Explanation

The PhishingController currently supports scanning single URLs for
phishing detection, but there are cases where we need to check multiple
URLs at once for efficiency. This PR adds a new `bulkScanUrls` method
that allows scanning up to 250 URLs in a single operation, improving
performance when multiple URLs need to be checked.

The implementation includes:
- A new `bulkScanUrls` method that can process up to 250 URLs (in
batches of 50)
- URL validation for length and quantity limits
- Error handling for API errors, timeouts, and validation failures
- Parallel processing of URL batches for improved performance

## References

* Implements new bulk scan API endpoint functionality
* Related to improved phishing detection performance

Subject: [PATCH 0309/1148] Feat/scan url cache (#5625)

## Explanation

The PhishingController's `scanUrl` method currently makes an API call
for every URL scan request, even when we've recently scanned the same
URL.

To address this, I've added a caching layer that:
1. Stores scan results in a persistent cache
2. Checks the cache before making API calls
3. Automatically expires cached entries after a configurable TTL
(default: 5 minutes)
4. Manages cache size with an LRU-based eviction policy when it exceeds
the maximum size (default: 100 entries)

This should reduce redundant API calls while maintaining security by
respecting TTL for cached entries.

### Explanation

The bulk URL scanning functionality in PhishingController previously
didn't leverage the URL scan cache that was already implemented for
single URL scanning. This meant that even if a URL had been recently
scanned, it would be scanned again when included in a bulk scan request,
causing unnecessary API calls and increased response times.

This PR extends the caching functionality to the `bulkScanUrls` method,
allowing it to:
1. Check the cache for each URL before sending API requests
2. Only scan URLs that aren't already in the cache
3. Add newly scanned results to the cache for future use
4. Return a combined response of both cached and newly scanned results

This optimization significantly reduces API calls and improves response
times for bulk scan operations, especially when the same URLs are
frequently scanned.

 ### Changed
 
+- Enhance `bulkScanUrls` method to leverage URL scan cache for improved performance ([#5688](https://github.com/MetaMask/core/pull/5688))
+  - URLs are now checked against the cache before making API requests
+  - Only uncached URLs are sent to the phishing detection API
+  - API results are automatically stored in the cache for future use
 - Bump `@metamask/controller-utils` to `^11.7.0` ([#5583](https://github.com/MetaMask/core/pull/5583))

Subject: [PATCH 0314/1148] fix: native EVM exchange rates and snap handler
 calls (#5696)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

- Fixes missing EVM native exchange rates by not lowercasing the symbol
used for lookups ([#5696](https://github.com/MetaMask/core/pull/5696))
- Fixes occasional snap handleRequest errors by setting the request
scope to SolScope.Mainnet instead of reading it from the account
metadata ([#5696](https://github.com/MetaMask/core/pull/5696))

## References

Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?

Subject: [PATCH 0316/1148] fix: remove chain id current chain from token rate
 controller (#5645)

## Explanation
Refactor tokenRatesController and Remove Legacy current Network
Dependencies
the changes contains:

**Removal of Network Dependencies:**
All current network dependencies have been removed, and the private
property `#chainId` is no longer used.

**Parallel API Requests:**
Requests sent to the price API are now executed in parallel. This
enhancement improves performance by reducing the overall time required
to fetch data.

**Optimized State Update:**
Instead of triggering multiple state updates (and consequently
re-renders) for each individual API response, the implementation now
waits for all requests to complete and then updates the state once. This
reduces unnecessary re-renders and optimizes the application's
performance.

* If you had to upgrade a dependency, why did you do so?

## Changelog

### `@metamask/assets-controllers`

- **UPDATE:** Refactor `TokenRatesController` to support processing
multiple chains simultaneously. The controller now accepts an array of
chain IDs and tickers instead of a single value, streamlining the
polling process by iterating over all chains in one loop.
- **BREAKING:** Eliminate legacy network dependency handling in
`TokenRatesController`. Clients must now pass an array (rather than a
single object) for chain IDs and tickers. This change may require
updates on the client side to align with the new array-based input.

Subject: [PATCH 0317/1148] feat: Add more chain-agnostic-permission utility
 functions from sip-26 usage (#5609)

## Changelog

### Added

- Added `getCaipAccountIdsFromScopesObjects`,
`getCaipAccountIdsFromCaip25CaveatValue`,
`isInternalAccountInPermittedAccountIds`, and
`isCaipAccountIdInPermittedAccountIds` account id functions.
([#5609](https://github.com/MetaMask/core/pull/5609))
- Added `getSupportedScopeObjects`, `getAllScopesFromScopesObjects`,
`getAllScopesFromCaip25CaveatValue`,
`getAllNonWalletNamespacesFromCaip25CaveatValue`,
`getAllScopesFromPermission`, `getAllScopesFromCaip25CaveatValue`, and
`isNamespaceInScopesObject`
  scope functions. ([#5609](https://github.com/MetaMask/core/pull/5609))
- Added `isKnownSessionPropertyValue` and
`getCaip25CaveatFromPermission` misc functions.
([#5609](https://github.com/MetaMask/core/pull/5609))

Subject: [PATCH 0318/1148] NetworkController: Add way to customize block
 tracker (#5702)

Add an optional `getBlockTrackerOptions` argument to NetworkController,
which can be used to customize the block tracker for a particular
network (or all networks if desired). This is particularly useful when
finetuning the behavior of the RPC failover logic.

Subject: [PATCH 0326/1148] feat: add `gasTransfer` to `GasFeeToken` (#5681)

## Explanation

Persist gas limit of gas fee token transfer transaction, returned from
simulation API.

Specifically:

- Add `gasTransfer` to `GasFeeToken`.
- Move simulation API to `api` directory.

Subject: [PATCH 0328/1148] CHANGED - add concurrency to high volume workflows
 (#5709)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## **Description**

By default, GitHub Actions allows multiple jobs within the same
workflow, multiple workflow runs within the same repository, and
multiple workflow runs across a repository owner's account to run
concurrently. This means that multiple instances of the same workflow or
job can run at the same time, performing the same steps.

https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/control-the-concurrency-of-workflows-and-jobs

GitHub Actions also allows you to disable concurrent execution. This can
be useful for controlling your account’s or organization’s resources in
situations where running multiple workflows or jobs at the same time
could cause conflicts or consume more Actions minutes and storage than
expected.

Subject: [PATCH 0330/1148] fix: add support for sonic network (#5711)

## Explanation

This PR adds support for Sonic mainnet chainId in the list
`SUPPORTED_CHAIN_IDS` so that tokenRatesController is able to fetch
prices for tokens for this network.

Subject: [PATCH 0331/1148] fix: remove usage current network from tokens
 controller (#5659)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

The current implementation of `TokensController` relies heavily on a
single selected network (`chainId`) as an instance property, which makes
multi-chain token handling brittle and hard to scale. Additionally, some
token operations unintentionally assume a persistent network context,
introducing potential bugs when switching networks or performing actions
concurrently across different chains.

This PR refactors the `TokensController` to eliminate reliance on an
internal `#chainId` property. Instead, all methods that require a
network context now accept a `networkClientId` as an explicit parameter.
This improves the controller’s ability to operate safely and predictably
in a multi-chain environment.

The `#onNetworkDidChange` logic and associated subscription were removed
since network changes are now handled at the method level with explicit
`networkClientId` parameters. All relevant internal state mutations and
token metadata fetches are scoped to the appropriate chain via the
`networkClientId -> chainId` mapping.

This refactor is part of a broader initiative to support simultaneous
multi-chain state handling across the codebase (see recent changes to
`TokenRatesController` and `AccountTrackerController`).

## Changelog

### `@metamask/assets-controllers`

- **UPDATE:** Refactor `TokensController` to support handling multiple
chains in parallel. All network-dependent methods now require an
explicit `networkClientId` parameter, enabling token operations to be
fully scoped to a specific chain. This improves reliability and
predictability when managing tokens across different networks.
- **BREAKING:** Remove internal reliance on a single `chainId` instance
property in `TokensController`. All chain-specific logic has been
externalized. Consumers must now explicitly pass a `networkClientId` to
methods that interact with the token state. This change may require
updates on the client side to ensure correct chain context is provided
during token actions.

Subject: [PATCH 0332/1148] fix: remove addDetectedToken call to unblock bridge
 status polling (#5716)

## Explanation

Fixes balance and status updates after submitting a bridge transaction
by skipping adding the new tokens

This is not a breaking change and clients can remove the
`TokensController:addDetectedTokens` allowed action from the
BridgeStatusController's initialization afterwards

Note that for testing, the mobile/extension wallets will need to be
reinstalled in order to remove bad token data added to the
TokenBalancesController

Subject: [PATCH 0336/1148] NetworkController: Add flag for controlling RPC
 failover behavior (#5668)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Recently we added some new behavior to NetworkController which will
detect if an Infura RPC endpoint is down and allow for forwarding
traffic to Quicknode automatically. Because this behavior involves
integrating with backend services to enable Quicknode on failure, we are
unsure whether everything will work the way we want to on the first try,
so we want to be able to disable or enable the behavior using feature
flags. That is, when turned off, even if an RPC endpoint has been
configured with failover URLs, network traffic will not be forwarded to
the failovers if the primary is perceived to be down.

There are a couple of things to note about this commit:

- Usually we would have NetworkController listen to
RemoteFeatureFlagController to know when a feature flag was enabled or
disabled and then enable or disable the RPC failover behavior
accordingly. Because we don't intend to keep the feature flag forever,
however, we let the clients do that and we simply expose methods in
NetworkController that can be used manually by the clients.
- The way that the enabling/disabling works is a bit tricky. Naively, we
could create new versions of network client objects that have different
sets of RpcService objects, and replace the existing versions directly
in the network client registry (without updating their IDs). That's a
little weird, though, and it also means that if another controller
caches a network client at any point in time, the cached version would
not be updated. So instead, we take advantage of the fact that when
other controllers interact with a network client, it's really a proxy —
an AutoManagedNetworkClient — and so we can replace the underlying
object (a NetworkClient) without changing the proxy.

 ### Added
 
 - Add optional `getBlockTrackerOptions` argument to NetworkController constructor ([#5702](https://github.com/MetaMask/core/pull/5702))
+- Add optional `rpcFailoverEnabled` option to NetworkController constructor (`false` by default) ([#5668](https://github.com/MetaMask/core/pull/5668))
+- Add `enableRpcFailover` and `disableRpcFailover` methods to NetworkController ([#5668](https://github.com/MetaMask/core/pull/5668))

 - Bump `@metamask/base-controller` from ^8.0.0 to ^8.0.1 ([#5722](https://github.com/MetaMask/core/pull/5722))
+- Disable the RPC failover behavior by default ([#5668](https://github.com/MetaMask/core/pull/5668))
+  - You are free to set the `failoverUrls` property on an RPC endpoint, but it won't have any effect

Subject: [PATCH 0340/1148] chore: add metadata to account controller options
 for EVM HD accounts (#5618)

## Explanation

In the multi-SRP context, we need to bubble up the Account metadata such
that it is available in interactions with the AccountsController.
This metadata will be used by the Backup & Sync feature to determine how
to reconstruct the account when restoring from backup.

Subject: [PATCH 0344/1148] feat: use remote-feature-flag-controller for bridge
 flags (#5708)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR updates the `BridgeController` to consume feature flags from the
`RemoteFeatureFlagController` rather than the Bridge API.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

Subject: [PATCH 0347/1148] fix: NotificationServicesController - check keyring
 state when using stateChange event (#5731)

## Explanation

Uncovered on extension. I haven't pieced all the moving parts together
but notifications essentially perform:

- Listens to `KeyringController:stateChange` events
- When receiving an event we perform a `KeyringController:withKeyring`
action.

Somewhere above (or potentially another controller?) will then fire
another `KeyringController:stateChange`, and we have a infinite loop
preventing other redux or state updates.

Now we will check the size of the keyring to better assume if accounts
have been added or removed.

Subject: [PATCH 0349/1148] Fix unmocked block tracker warning in
 GasFeeController tests (#5297)

When running the tests for GasFeeController, we were seeing many
warnings in the test output indicating that a request from the block
tracker was not properly mocked. This commit adds that mock so the
warning goes away.

Subject: [PATCH 0352/1148] fix: do not throw error when encryption upgrade
 fails during login (#5740)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
There's a mechanism in KeyringController to upgrade the vault encryption
parameters during a successful login to ensure users always use the
safest encryption available without needing additional actions for the
vault to be upgraded.

However, when the vault encryption upgrade fails during login, we don't
want to interrupt and rollback the entire operation. We can move the
vault upgrade to a standalone, mutually exclusive operation that can
fail gracefully.

This fix can be tested on extension with this draft PR (instructions
included): https://github.com/MetaMask/metamask-extension/pull/32438

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->
* Fixes https://github.com/MetaMask/core/issues/5745

Subject: [PATCH 0354/1148] feat: generate EIP-7702 gas fee tokens (#5706)

## Explanation

Include `authorizationList` and `with7702` properties in simulation
request to return EIP-7702 gas fee tokens, and include upgrade gas.

Add optional `isEIP7702GasFeeTokensEnabled` property to constructor.

Subject: [PATCH 0357/1148] fix: use solana chainId as scope when submitting
 bridge txs (#5750)

## Explanation

Imported solana accounts do not have the `options.scope` value set so
the solana chainId needs to be specified when submitting transactions

Subject: [PATCH 0359/1148] perf(keyring-controller): do not fire unnecessary
 `:stageChange` in `withKeyring` (#5732)

## Explanation

We were always calling `#updateVault` when using `withKeyring` even when
the keyring was not mutated.

This PR now compare the states after the operation execution and see if
the keyring got updated or not and decide to call `#updateVault` only if
needed.

Testing PR:
- https://github.com/MetaMask/metamask-extension/pull/32414

Subject: [PATCH 0360/1148] Fix `getAllNamespacesFromCaip25CaveatValue` to
 return only reference when value is wallet namespaced (#5759)

## Explanation

Fixes `getAllNamespacesFromCaip25CaveatValue` to return only the
reference of the passed in scope string when it is `wallet` namespaced.
I.e. `wallet:eip155` should return only `eip155` and an exact value of
`wallet` should still return `wallet.

Subject: [PATCH 0362/1148] Release 388.0.0 (#5763)

Release candidates that includes some important perf improvements for
the Snap account creation flow.
- Prevent some unnecessary `KeyringController:stateChange` when using
`withKeyring`
- Prevent some unnecessary `AccountsController:stateChange` when
handling `SnapController:stateChange`
- Combine multiple actions into 1, to avoid multiple `.update` blocks

Subject: [PATCH 0363/1148] feat: add `Monad Testnet` to `network-controller`
 and `controller-utils`  (#5724)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR is to add Monad Testnet as default network on
`network-controller` default state - `networkConfigurationsByChainId`
with the constants and type from the latest `controller-utils`

### Changes:

- Refactor `network-controller`
methods`getDefaultCustomNetworkConfigurationsByChainId` to build the
configuration from `CustomNetworkType` instead of hardcode network 1 by
1

- Add `Monad Testnet` info into `controller-utils`
- Include `Monad Testnet` into `network-controller` method
`getDefaultCustomNetworkConfigurationsByChainId`

Subject: [PATCH 0364/1148] refactor: NotificationServicesController to use
 KeyringController:getState to grab the first HD keyring (#5764)

## Explanation

This uses `KeyringController:getState` instead of
`KeyringController:withKeyring` for faster execution and avoids any
additional events that `withKeyring` emits.

**Breaking** - this removes the allowed action
`KeyringController:withKeyring`.

Subject: [PATCH 0365/1148] fix(multichain-network-controller): batch requests
 for active networks (#5752)

## Explanation

This PR implements request batching for the Network Activity API to
accommodate a new limitation imposed by the API platform team. The API
endpoint now caps requests at 20 account IDs per call to prevent URL
length limitations in some browsers.

### Key Changes

- Modified `MultichainNetworkService` to handle batching of account IDs
in groups of 20
- Added internal batch processing logic to maintain the same public
interface
- Updated tests to validate correct batching behavior

Subject: [PATCH 0368/1148] fix: include origin in 7702 transaction (#5771)

## Explanation

Include `origin` in call to `addTransaction` from EIP-7702 batch
transaction.

Wasn't causing a linting error as `origin` is default global variable.

Subject: [PATCH 0370/1148] feat: rename profile sync to backup and sync
 (#5686)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR updates all profile syncing references to backup and sync.
This involves state properties name changes, so the clients will need to
write migrations when bumping.

This is a **breaking** change.

Instructions for client migration are basically the test drive PRs
below:

- ✅ Extension test drive PR:
https://github.com/MetaMask/metamask-extension/pull/32572
- ✅ Mobile test drive PR:
https://github.com/MetaMask/metamask-mobile/pull/15211

Subject: [PATCH 0371/1148] Release/390.0.0 (#5777)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Main reason for the release is to change the url endpoint for the defi
adapters api from dev to prod. It is the same endpoint and has no
breaking changes.

It also includes a minor dependency bump for
`@metamask/controller-utils` from 11.7.0 to 11.8.0.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

Subject: [PATCH 0372/1148] fix: improve multichainTokenBalances and
 multichainAssetsRates controller state updates (#5761)

## Explanation

Both `MultichainTokenBalancesController` and
`MultichainAssetsRatesController` used to subscribe to
`MultichainAssetsController:stateChange` which was triggering state
updates for all existing accounts on every update.

Instead; MultichainAssetsController will now publish new event
`MultichainAssetsController:newAccountAssets` that is published whenever
new assets are added for specific accounts, and controllers can
subscribe to that instead.

Subject: [PATCH 0377/1148] fix: remove metadata for unsupported keyrings
 (#5725)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?

* If you had to upgrade a dependency, why did you do so?
-->
When the user vault is decrypted and there is an attempt to restore an
unsupported/deprecated/faulty keyring there's no mechanism to remove
related metadata, which leads to a situation where no further action can
be made on the controller, because checks for keyrings and metadata
length will fail.

We could remove the related metadata object when the keyring restore
fails, but then we would lose the original ID generated for the keyring.
We can, instead, change the place where the metadata is stored from a
state property to the encrypted vault: by placing the metadata along
with its serialised keyring in the vault we can guarantee a 1:1 link
between them while being able to keep metadata for unsupported keyrings.

Given that we don't need to use the KeyringController state to persist
metadata anymore (as it is persisted along with the vault), we can also
remove `keyringsMetadata` completely, and add a `metadata` attribute to
each keyring in `state.keyrings` instead - which won't be persisted, as
it will be recreated at runtime every time the vault is decrypted and
the keyrings are deserialised.

 ## [Unreleased]
 
+### Changed
+
+- **BREAKING** `keyringsMetadata` has been removed from the controller state ([#5725](https://github.com/MetaMask/core/pull/5725))
+  - The metadata is now stored in each keyring object in the `state.keyrings` array.
+  - When updating to this version, we recommend removing the `keyringsMetadata` state and all state referencing a keyring ID with a migration. New metadata will be generated for each keyring automatically after the update.

Subject: [PATCH 0384/1148] fix: cancelled bridge quote request handling
 (#5787)

## Explanation

When the quote request polling is cancelled, the quote request metadata
fields in state don't get reset, which can cause polling to stop
prematurely on clients.

Subject: [PATCH 0386/1148] fix: discard duplicate accounts on unlock (#5775)

Dependent on:
- https://github.com/MetaMask/core/pull/5725

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
It is no longer possible to persist duplicates in the vault, though
users that already have duplicates will see them in the accounts list,
and won't be able to do any action with their vault. These changes aim
to discard duplicates, moving the keyring including a duplicate account
to the unsupported array.

Can be tested on extension with
https://github.com/MetaMask/metamask-extension/pull/32621

Subject: [PATCH 0389/1148] perf: improve token-list-controller state updates
 and caching (#5804)

## Explanation

This improves how we perform state updates in the TokenListController.

It reduces the mobile commits/renders from 27-30 commits down to 10-15.
Here is a test-drive mobile PR:

Subject: [PATCH 0390/1148] fix(rpc-service): handle 405 and 429 status codes
 without triggering circuit breaker (#5798)

## Explanation
This PR improves the handling of HTTP status codes in the RPC service by
properly handling 405 (Method Not Allowed) and 429 (Too Many Requests)
responses without triggering the circuit breaker.

### Changes
- Added handling for 405 status code, RPC Error code -32601 (Method not
found)
- Added handling for 429 status code, RPC Error code-32005 (Request rate
limit exceeded)

### Why
Previously, these status codes would trigger the circuit breaker, which
could lead to unnecessary failover to backup endpoints. These status
codes represent expected error conditions that should be handled
gracefully without triggering the circuit breaker.

### Testing
- [ ] Test with 405 response to verify proper error handling
- [ ] Test with 429 response to verify proper error handling and retry
delay information
- [ ] Verify circuit breaker is not triggered for these status codes

## References

* Fixes https://github.com/MetaMask/core/issues/5766

+- Improved circuit breaker behavior to only consider specific error codes as service failures ([#5798](https://github.com/MetaMask/core/pull/5798))
+  - Changed from using `handleAll` to `handleWhen(isServiceFailure)` in circuit breaker policy
+  - This ensures that expected error responses (like 405 Method Not Allowed and 429 Rate Limited) don't trigger the circuit breaker
+  - Only considers as service failures:
+    - Errors that have a numeric code property with value -32603 (Internal error)
+    - Errors that don't meet the criteria for having a numeric code property
+  - With more precise type checking for the error object structure

+- Improved handling of HTTP status codes to prevent unnecessary circuit breaker triggers ([#5798](https://github.com/MetaMask/core/pull/5798))
+  - 405 (Method Not Allowed) continues to throw JSON-RPC error with code -32601 (Method not found)
+  - 429 (Too Many Requests) now throws JSON-RPC error with code -32005 (Request rate limit exceeded) instead of a generic internal error
+  - These errors are filtered by the circuit breaker's `handleWhen` policy to prevent unnecessary failover to backup endpoints

Subject: [PATCH 0391/1148] feat: incoming transaction request tags (#5803)

## Explanation

Support additional debug data in `x-metamask-clientproduct` header in
incoming transaction requests to accounts API.

Provided via optional `tags` in calls to `updateIncomingTransactions`,
and optional `client` in constructor.

## References

Fixes [#4902](https://github.com/MetaMask/MetaMask-planning/issues/4902)

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0392/1148] chore: Remove obsolete workaround (#5808)

## Explanation

An error case was added to our network middleware long ago to workaround
load balancer errors that we encountered with Infura at the time. These
errors were fixed long ago, so this workaround is no longer needed.

I checked with the Infura team, and they confirmed that this case should
no longer be possible for Infura RPC endpoints.

Removing this check allowed me to update how we're parsing the response
body as well. We're now using `response.json()` rather than parsing the
raw body as text. As a consequence of this, we no longer have the raw
text to attach to parsing errors, but this seems OK to remove given that
we don't reference it anywhere, and the full response can be seen in
devtools in a development environment.

## References

This workaround was originally introduced here:

Subject: [PATCH 0393/1148] fix: use zero address as native address instead of
 assetId (#5799)

## Explanation

`getNativeAssetForChainId` returns the assetId for SOL instead of a
recognized native token address. This can cause duplicate SOL tokens to
appear in the clients. This updates the address to the ZeroAddress,
which clients use for native assets

Subject: [PATCH 0395/1148] fix: Prevent circuit break for HTTP 4XX errors
 (#5809)

## Explanation

The "create-service-policy" utility (specifically the circuit breaker)
has been updated to handle fetch errors rather than RPC errors.

This utility was recently updated to handle the JSON-RPC "Internal
error" response, but this is only expected for one specific place where
this utility is used (the RPC service). Additionally, there remained
some cases that would still inappropriately trigger the circuit break
policy (i.e. there were some "internal errors" that don't indicate
service failure).

The utility will now consider all network errors and HTTP 5XX errors as
indicative of service failure. HTTP 4XX errors will no longer trigger
the circuit breaker.

To accomodate these changes, the RPC service now only handles the fetch
request and response parsing inside the policy execution phase. The step
where errors are parsed and converted to JSON-RPC errors has been moved
to _outside_ the execute step. Effectively this has the same functional
result for users of the service, but it makes the policy much simpler.

 ### Fixed
 
-- Improved handling of HTTP status codes to prevent unnecessary circuit breaker triggers ([#5798](https://github.com/MetaMask/core/pull/5798))
-  - 405 (Method Not Allowed) continues to throw JSON-RPC error with code -32601 (Method not found)
-  - 429 (Too Many Requests) now throws JSON-RPC error with code -32005 (Request rate limit exceeded) instead of a generic internal error
-  - These errors are filtered by the circuit breaker's `handleWhen` policy to prevent unnecessary failover to backup endpoints
+- Improved handling of HTTP status codes to prevent unnecessary circuit breaker triggers ([#5798](https://github.com/MetaMask/core/pull/5798), [#5809](https://github.com/MetaMask/core/pull/5809))
+  - HTTP 4XX responses (e.g. rate limit errors) will no longer trigger the circuit breaker policy.

Subject: [PATCH 0398/1148] feat: Update `txParams` gas properties in when
 controller `updateTransactionGasFees` method is called with `userFeeLevel`
 (#5800)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR aims to add automatic update `txParams` gas values when
controller `updateTransactionGasFees` method is called with
`userFeeLevel`.

Making this change will give us cleaner logic in the clients since
controller does that update.

Fix in action:

Subject: [PATCH 0400/1148] Use selected network controller for Snaps (#4602)

## Explanation

This removes some checks in the `SelectedNetworkController` which
disallow a Snap from using their own network, and default to the
globally selected network. After this change, Snaps will be able to
select their own network just like websites.

## References

Related to MetaMask/MetaMask-planning#2938.

Subject: [PATCH 0401/1148] feat(multichain-transactions-controller)!: store
 transactions by chain ID (support for devnet chains) (#5756)

## Explanation

1. Removes the Solana mainnet filtering
2. Reorganizes data structure to support an account[] -> chain[] ->
transactions
```
  nonEvmTransactions: {
    [accountId: string]: {
      [chain: string]: TransactionStateEntry;
    };
  };
```
3. Updates logic to reflect these changes

Subject: [PATCH 0402/1148] update @metamask/api-specs version to v0.14.0 in
 @metamask/chain-agnostic-permission + @metamask/multichain-api-middleware
 (#5817)

## Explanation

Update @metamask/api-specs version to v0.14.0 in:
`@metamask/chain-agnostic-permission`
`@metamask/multichain-api-middleware`
`@metamask/multichain` - to be deprecated soon


## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0404/1148] feat: log bridge quote and status validation errors
 (#5816)

## Explanation

bridge-api responses are ignored if they fail schema validation. This
can cause issues like
- not showing quotes to the user
- tx statuses getting stuck due to dropped status updates

This PR adds error logging that we can monitor on Sentry. Here's an
example trace that includes validation errors:
https://metamask.sentry.io/insights/frontend/summary/trace/f058862e687a4946a72377f7fc6b6c1f/?node=txn-1e62b796f286424ea5f1635cd84564b7&project=273496&query=transaction.op%3Acustom&referrer=performance-transaction-summary&source=performance_transaction_summary&statsPeriod=5m&timestamp=1747356475&transaction=Bridge%20Quotes%20Fetched&unselectedSeries=p100%28%29&unselectedSeries=avg%28%29

Subject: [PATCH 0406/1148] fix: Fix sending native token to smart account
 (#5822)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR aims to fix where the `addTransaction` function incorrectly
identifies a transaction as a `simpleSend` type when the recipient is a
smart account.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

Subject: [PATCH 0408/1148] feat: add types for unified bridge ui (#5783)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Adds `isUnifiedUIEnabled` flag to `ChainConfiguration` feature-flag type
and update validators accordingly. This is required as we are adding a
feature flag to support the development of a unified bridge/swap UI.

Subject: [PATCH 0411/1148] feat: add sequential batch support (#5762)

## Explanation

The `TransactionController` currently lacks support for sequential batch
transactions, which are required for the stablecoin lending feature.
Specifically, there is no mechanism to execute multiple transactions
(e.g., approval + token deposit) sequentially while ensuring
confirmation for each transaction. This limitation prevents efficient
batch processing to support new features.

**What solution do these changes offer?**
The `SequentialPublishBatchHook` introduces a default mechanism for
handling batch transactions when no custom `publishBatchHook` is
provided. It ensures transactions are published sequentially, waiting
for confirmation before proceeding to the next. If any transaction fails
to publish or confirm, the batch process halts and throws an error.

**Key Features:**

- Sequential Execution: Publishes transactions one at a time and waits
for confirmation.
- Error Handling: Halts the batch if any transaction fails to publish or
confirm.
- Polling for Confirmation: Retries confirmation checks up to a maximum
number of attempts.

Subject: [PATCH 0412/1148] fix: don't poll for swap status (#5831)

## Explanation

After a swap is submitted the status controller keeps calling
getTxStatus. This is unnecessary and can cause clients to keep polling
until the user clears their activity log

Subject: [PATCH 0418/1148] fix: Remove lingering decimal in return of
 `gweiDecimalToWeiDecimal` (#5839)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR aims to fix minor issue on `gweiDecimalToWeiDecimal` utility.

If given value is more than 9 decimal places then generated WEI value
will have decimal part which we don't expect / want in WEI value.

Subject: [PATCH 0422/1148] feat(accounts-controller): Add `entropySource` to
 new `InternalAccount` (#5841)

## Explanation

`AccountsController:accountAdded` events were missing the
`.options.entropySource` property, causing account syncing to misbehave,
registering new accounts to the primary SRP instead of the actual SRP
used to add the account.

We now add the `entropySource` to these new `InternalAccount`s based on
the `keyring` that was used to create them.

Subject: [PATCH 0423/1148] Add swappable param to discovery endpoints (#5819)

## Explanation

* What is the current state of things and why does it need to change?
token discovery controller doesn't know about the swappable* endpoints
of the token discovery API
* What is the solution your changes offer and how does it work? add
swappable* versions of the discovery endpoints to the controller + api
service
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain? no
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so? N/A
* If you had to upgrade a dependency, why did you do so? N/A

Subject: [PATCH 0424/1148] remote-feature-flag-controller: Fix flaky test
 (#5730)

The test for `generateDeterministicRandomNumber` sometimes fails because
it relies on the behavior of `uuidv4`, which is non-deterministic, and
needs to be more lenient in the range of acceptable return values.

Subject: [PATCH 0426/1148] chore: reduce tokenBalances state updates (#5726)

## Explanation

When a user removes an account; tokenBalances controller would still
fetch balances for the tokens and update state.
This was happening because tokensController does not remove tokens from
state when a user removes the account.

This PR cleans up tokens from tokensController state once a user removes
an account.
It also cleans up the balances from state when the user removes the
account.

This PR also adds a check to see if token balances has changed after
fetching them; if none of the balances changed; no need to update state.

Subject: [PATCH 0428/1148] Add `@metamask/error-reporting-service` (#5849)

This package makes it possible for any module to report an error to an
error reporting app (such as Sentry). The exact mechanism to do so is
customizable, and the service object exposes a messenger action so that
modules can report the error without needing direct access to the
service object itself.

+# `@metamask/error-reporting-service`
+
+Reports errors to an external app such as Sentry but in an agnostic fashion.
+
+## Installation
+
+`yarn add @metamask/error-reporting-service`
+
+or
+
+`npm install @metamask/error-reporting-service`
+
+## Usage
+
+This package is designed to be used in another module via a messenger, but can also be used on its own if needed.
+
+### Using the service via a messenger
+
+In most cases, you will want to use the error reporting service in your module via a messenger object.
+
+In this example, we have a controller, and something bad happens, but we want to report an error instead of throwing it.
+
+#### 1. Controller file
+
+```typescript
+// We need to get the type for the `ErrorReportingService:captureException`
+// action.
+import type { ErrorReportingServiceCaptureExceptionAction } from '@metamask/error-reporting-service';
+
+// Now let's set up our controller, starting with the messenger.
+// Note that we grant the `ErrorReportingService:captureException` action to the
+// messenger.
+type AllowedActions = ErrorReportingServiceCaptureExceptionAction;
+type ExampleControllerMessenger = RestrictedMessenger<
+  'ExampleController',
+  AllowedActions,
+  never,
+  AllowedActions['type'],
+  never
+>;
+
+// Finally, we define our controller.
+class ExampleController extends BaseController<
+  'ExampleController',
+  ExampleControllerState,
+  ExampleControllerMessenger
+> {
+  doSomething() {
+    // Now imagine that we do something that produces an error and we want to
+    // report the error.
+    this.messagingSystem.call(
+      'ErrorReportingService:captureException',
+      new Error('Something went wrong'),
+    );
+  }
+}
+```
+
+#### 2A. Initialization file (browser)
+
+```typescript
+// We need a version of `captureException` from somewhere. Here, we are getting
+// it from `@sentry/browser`.
+import { captureException } from '@sentry/browser';
+
+// We also need to get the ErrorReportingService.
+import { ErrorReportingService } from '@metamask/error-reporting-service';
+
+// And we need our controller.
+import { ExampleController } from './example-controller';
+
+// We need to have a global messenger.
+const globalMessenger = new Messenger();
+
+// We need to create a restricted messenger for the ErrorReportingService, and
+// then we can create the service itself.
+const errorReportingServiceMessenger = globalMessenger.getRestricted({
+  allowedActions: [],
+  allowedEvents: [],
+});
+const errorReportingService = new ErrorReportingService({
+  messenger: errorReportingServiceMessenger,
+  captureException,
+});
+
+// Now we can create a restricted messenger for our controller, and then
+// we can create the controller too.
+// Note that we grant the `ErrorReportingService:captureException` action to the
+// messenger.
+const exampleControllerMessenger = globalMessenger.getRestricted({
+  allowedActions: ['ErrorReportingService:captureException'],
+  allowedEvents: [],
+});
+const exampleController = new ExampleController({
+  messenger: exampleControllerMessenger,
+});
+```
+
+#### 2B. Initialization file (React Native)
+
+```typescript
+// We need a version of `captureException` from somewhere. Here, we are getting
+// it from `@sentry/react-native`.
+import { captureException } from '@sentry/react-native';
+
+// We also need to get the ErrorReportingService.
+import { ErrorReportingService } from '@metamask/error-reporting-service';
+
+// And we need our controller.
+import { ExampleController } from './example-controller';
+
+// We need to have a global messenger.
+const globalMessenger = new Messenger();
+
+// We need to create a restricted messenger for the ErrorReportingService, and
+// then we can create the service itself.
+const errorReportingServiceMessenger = globalMessenger.getRestricted({
+  allowedActions: [],
+  allowedEvents: [],
+});
+const errorReportingService = new ErrorReportingService({
+  messenger: errorReportingServiceMessenger,
+  captureException,
+});
+
+// Now we can create a restricted messenger for our controller, and then
+// we can create the controller too.
+// Note that we grant the `ErrorReportingService:captureException` action to the
+// messenger.
+const exampleControllerMessenger = globalMessenger.getRestricted({
+  allowedActions: ['ErrorReportingService:captureException'],
+  allowedEvents: [],
+});
+const exampleController = new ExampleController({
+  messenger: exampleControllerMessenger,
+});
+```
+
+#### 3. Using the controller
+
+```typescript
+// Now this will report an error without throwing it.
+exampleController.doSomething();
+```
+
+### Using the service directly
+
+You probably don't need to use the service directly, but if you do, here's how.
+
+In this example, we have a function, and we use the error reporting service there.
+
+#### 1. Function file
+

+
+```typescript
+// We need a version of `captureException` from somewhere. Here, we are getting
+it from `@sentry/browser`.
+import { captureException } from '@sentry/browser';
+
+// We also need to get the ErrorReportingService.
+import { ErrorReportingService } from '@metamask/error-reporting-service';
+
+// We also bring in our function.
+import { doSomething } from './do-something';
+
+// We create a new instance of the ErrorReportingService.
+const errorReportingService = new ErrorReportingService({ captureException });
+
+// Now we call our function, and it will report the error in Sentry.
+doSomething(errorReportingService);
+```
+
+#### 2A. Calling file (React Native)
+
+```typescript
+// We need a version of `captureException` from somewhere. Here, we are getting
+it from `@sentry/react-native`.
+import { captureException } from '@sentry/react-native';
+
+// We also need to get the ErrorReportingService.
+import { ErrorReportingService } from '@metamask/error-reporting-service';
+
+// We also bring in our function.
+import { doSomething } from './do-something';
+
+// We create a new instance of the ErrorReportingService.
+const errorReportingService = new ErrorReportingService({ captureException });
+
+// Now we call our function, and it will report the error in Sentry.
+doSomething(errorReportingService);

Subject: [PATCH 0429/1148] fix(rpc-service): improve error handling for HTTP
 status codes (#5843)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Improves error handling in the RPC service by making it more specific
and consistent. The changes include:

- Clarifies error handling for different HTTP status codes:
  - 401: Unauthorized error
  - 402/404/5xx: Resource unavailable error
  - 405/501: Method not found error
  - 429: Rate limiting error
  - Other 4xx: Invalid request error
  - Invalid JSON: Parse error

+  - 401 responses now throw an "Unauthorized" error
+  - 402/404/5xx responses now throw a "Resource Unavailable" error
+  - 429 responses now throw a "Rate Limiting" error
+  - Other 4xx responses now throw a generic HTTP client error
+  - Invalid JSON responses now throw a "Parse" error
+
 ## [23.5.0]

Subject: [PATCH 0430/1148] feat(address-book): messaging updated and deleted
 events (#5779)

## Explanation

- Emit events on contact updates and deletions.
- List method to retrieve contacts stored locally.

## References

Needed by: https://github.com/MetaMask/core/pull/5776

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0431/1148] fix: detectTokens on tx confirmed (#5859)

## Explanation

This PR

- Adds subscription to `TransactionController:transactionConfirmed`
event in `tokenDetectionController` to attempt to detect new tokens and
update tokenList as soon as a transaction is confirmed as opposed to
waiting for 3mins before updating state.

- Adds account address along with accountId to payload when publishing
`AccountsController:accountRemoved` event

Subject: [PATCH 0433/1148] add missing `promptToCreateSolanaAccount` flag
 (#5856)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

If solana is a requested scope but not supported, we add a
`promptToCreateSolanaAccount` metadata flag to forward to the connection
UI

[See designs here for the "opt in" flow this
enables](https://www.figma.com/design/ZQKVsVg1yqve25sUJkX12Z/Solana-opt-in-Scenarios?node-id=0-1&p=f&t=4CjFuTjVgcAu1xw3-0)

## References

[Extension PR
](https://github.com/MetaMask/metamask-extension/pull/31544)- since
currently extension has its own `wallet_createSession` handler. We'll
consolidate these soon

## Changelog

`@metamask/multichain-api-middleware`
- Added: when `wallet_createSession` is called with
`solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp` as a requested scope, but
there are not currently any accounts in the wallet supporting this
scope, we add a `promptToCreateSolanaAccount` to a metadata object on
the requestPermissions call.

 ## [Unreleased]
 
+### Added
+
+- When `wallet_createSession` handler is called with `solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp` (solana mainnet) as a requested scope, but there are not currently any accounts in the wallet supporting this scope, we now add a `promptToCreateSolanaAccount` to a metadata object on the requestPermissions call.

### Added

- When `wallet_createSession` handler is called with
`solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp` (solana mainnet) as a
requested scope, but there are not currently any accounts in the wallet
supporting this scope, we now add a `promptToCreateSolanaAccount` to a
metadata object on the `requestPermissions` call forwarded to the
`PermissionsController`.

Subject: [PATCH 0435/1148] Adds `transactionBatches` into transaction
 controller state (#5793)

## Explanation

This PR introduces support for batch transactions in the Transaction
Controller by adding a new `ApprovalType` and extending the state to
handle `TransactionBatches`. These changes enable enhanced metadata
management for sequential batch flows, including UI updates for gas
estimation and future automation capabilities.

## Changes

### Controller Utils
- Added a new `ApprovalType` to the enum: `TransactionBatch`, to support
batch transactions.

### Transaction Controller
- Introduced a new state property: `transactionBatches`, to store
metadata for transaction batches.
- Added a private method: `addBatchMetadata`, responsible for populating
batch-specific metadata.
- Created a new type: `TransactionBatchMeta`, to manage metadata for
transaction batches.
- Add `addBatchMetadata` to store batch metadata and
`wipeTransactionBatches` to clean up state after batch hook completion.
- Update unit tests

## Rationale

The introduction of `TransactionBatchMeta` allows for a clean separation
of metadata for batch transactions, which conceptually differ from
individual transactions. This ensures:
- Accurate metadata at the time of batch creation, as `TransactionMeta`
for individual transactions may not yet exist.
- Future support for advanced features such as transaction simulations
and dynamic gas fee updates for batches, enabling better client-side
functionality and automation.

These changes lay the groundwork for improved handling of batch
transactions and pave the way for future enhancements.

Subject: [PATCH 0439/1148] feat: integrate phishing protection into
 NftController (#5598)

## Explanation

# NFT Metadata URL Safety: Moving Phishing Detection from UI to
Controller

## Overview
This PR implements security enhancements by moving NFT metadata URL
safety checks from the UI layer to the controller level. It ensures
potentially malicious URLs in NFT metadata are detected and filtered
before reaching the UI components.

## Changes
- Added URL safety scanning to the `NftController` that checks all
external links in NFT metadata
- Implemented phishing detection using `PhishingController`'s URL
scanning capability
- Added caching mechanism to reduce redundant URL checks
- Implemented concurrent URL processing with controlled batch sizes
- Added sanitization of NFT metadata to remove unsafe URLs

## Technical Details
- Added a new method `#sanitizeNftMetadata` that checks all URLs in
metadata
- Added URL safety check implementation with `PhishingController`
integration
- Modified `_getNftInformation` to sanitize metadata after retrieval
- Implemented filtering for various URL types (image, animation,
external links)
- Added safety configuration with allowed protocols and denied domains


<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?

Subject: [PATCH 0442/1148] feat: defi metrics (#5868)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
N/A
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
N/A
* If you had to upgrade a dependency, why did you do so?
-->

The new defi positions feature is missing a way to track the count of
defi positions
This PR adds the ability to optionally pass metric tracking function to
the DeFi position controller

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

Subject: [PATCH 0443/1148] Correct invalid initial selectedNetworkClientId
 (#5851)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, when NetworkController is instantiated with pre-existing
state that contains an invalid `selectedNetworkClientId` — that is, no
RPC endpoint exists which has the same network client ID — then it
throws an error. This was intentionally done to bring attention to
possible bugs in NetworkController, but this has the unfortunate side
effect of bricking users' wallets.

To fix this, we now correct an invalid `selectedNetworkClientId` to
point to the default RPC endpoint of the first network sorted by chain
ID (which in the vast majority of cases will be Mainnet). We still do
want to know about this, though, so we log the error in Sentry.

Subject: [PATCH 0445/1148] Includes `origin` for `wallet_sendCalls` security
 alert requests (#5876)

## Explanation

This PR ensures the origin (URL) that initiates a `wallet_sendCalls`
request is sent to the security alerts API. This additional context is
important for improving PPOM validation and threat detection accuracy.

Changes:

- Added `origin`  property to `ValidateSecurityRequest` type.
- Updated `validateSecurity` callback to pass the `origin`.

Subject: [PATCH 0446/1148] Fix block tracker not resolving for failed requests
 (#5860)

Currently, if a consumer makes a request to an RPC endpoint via a
network provider object, and that request continually fails in some way
and then throws a circuit breaker error, it will never resolve.
Naturally, this causes problems if the consuming code (e.g.
TransactionController, or UI code) is expecting a response from the
network in order to proceed.

This problem occurs because internally the NetworkController wraps
requests in special middleware that use the block tracker to get the
latest block number. This middleware gets executed before the desired
request reaches the network, and in this case because the block tracker
does not return a resolved promise, the middleware does not resolve
along with the entire request.

This bug has been resolved in `@metamask/eth-block-tracker` 12.0.1 and
`@metamask/eth-json-rpc-middleware` 17.0.1. So, to fix this problem,
this PR upgrades these packages.

Subject: [PATCH 0447/1148] feat: Seedless Onboarding Controller (#5874)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
Adds new seedless onboarding controller. This controller allows MM
extension and mobile users to login with google, apple accounts. This
controller communicates with web3auth nodes + relies on toprf sdk
(unreleased) to perform CRU operations related to backing up srps.

The full list of operations supported are as follows:
- Authenticate OAuth user using the seedless onboarding flow and
determine if the user is already registered or not
- Create a new Toprf key and backup seed phrase
- Add a new seed phrase backup to the metadata store
- Add array of new seed phrase backups to the metadata store in batch
(useful in multi-srp flow)
- Fetch seed phrase metadata from the metadata store
- Update the password of the seedless onboarding flow

The controller also persists some data to the local encrypted vault
similar to keyring controller. This vault is encrypted with user
password and contains ek, sk related to toprf flow.
We also store backupHashes locally to showcase in settings page whether
a srp is backed up or not

The following items are not included in this PR and will be included in
the next one
- what to do when nodeAuthTokens are expired? - expires based on login
timeout - adding support for refresh tokens
- what to do when toprfEncryptionKey, toprfAuthKeyPair expire? - expires
when user changes password - solved by password syncing
- support password syncing when available (currently under design)

Adds new seedless onboarding controller. This controller allows MM
extension and mobile users to login with google, apple accounts. This
controller communicates with web3auth nodes + relies on toprf sdk
(unreleased) to perform CRU operations related to backing up srps.

The full list of operations supported are as follows:
- Authenticate OAuth user using the seedless onboarding flow and
determine if the user is already registered or not
- Create a new Toprf key and backup seed phrase
- Add a new seed phrase backup to the metadata store
- Add array of new seed phrase backups to the metadata store in batch
(useful in multi-srp flow)
- Fetch seed phrase metadata from the metadata store
- Update the password of the seedless onboarding flow

The controller also persists some data to the local encrypted vault
similar to keyring controller. This vault is encrypted with user
password and contains ek, sk related to toprf flow.
We also store backupHashes locally to showcase in settings page whether
a srp is backed up or not

The following items are not included in this PR and will be included in
the next one
- what to do when nodeAuthTokens are expired? - expires based on login
timeout - adding support for refresh tokens
- what to do when toprfEncryptionKey, toprfAuthKeyPair expire? - expires
when user changes password - solved by password syncing
- support password syncing when available (currently under design)

Subject: [PATCH 0450/1148] Revert "fix(rpc-service): improve error handling
 for HTTP status codes (#5843) (#5881)

This reverts commit 3fb3df497b6816c749e207c98fe5d18fa676f6d4. We want to
confirm that returning different kinds of errors won't break dapps
before we merge this.

 ### Fixed
 
-- Improved error handling in RPC service with more specific error types ([#5843](https://github.com/MetaMask/core/pull/5843)):
-  - 401 responses now throw an "Unauthorized" error
-  - 402/404/5xx responses now throw a "Resource Unavailable" error
-  - 429 responses now throw a "Rate Limiting" error
-  - Other 4xx responses now throw a generic HTTP client error
-  - Invalid JSON responses now throw a "Parse" error
 - Rather than throwing an error, NetworkController now corrects an invalid initial `selectedNetworkClientId` to point to the default RPC endpoint of the first network sorted by chain ID ([#5851](https://github.com/MetaMask/core/pull/5851))
 - Fix the block tracker so that it will now reject if an error is thrown while making the request instead of hanging ([#5860](https://github.com/MetaMask/core/pull/5860))

Subject: [PATCH 0451/1148] Release 415.0.0 (#5882)

This release primarily includes the following two fixes to
`network-controller`:

- Rather than throwing an error, NetworkController now corrects an
invalid initial `selectedNetworkClientId` to point to the default RPC
endpoint of the first network sorted by chain ID, then logs the error
via Sentry ([#5851](https://github.com/MetaMask/core/pull/5851))
- Fix the block tracker so that it will now reject if an error is thrown
while making the request instead of hanging
([#5860](https://github.com/MetaMask/core/pull/5860))

---

Full list of packages and versions in this release:

- `@metamask/error-reporting-service` (1.0.0)
- `@metamask/network-controller` (23.5.0 -> 23.5.1)

* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
Handle password sync flow
- Add checkIsPasswordOutdated method (which is cached for 15 mins)
- Add password check to fetch all SRPs and change password
- Add recover password method to recover old password using latest
global password
- Add sync latest global password to reset vault to use latest password
and persist latest auth pubkey

- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

   - Updated `VaultEncryptor` type in constructor args and is compulsory to provided relevant encryptor to constructor.
   - Added new non-persisted states, `encryptionKey` and `encryptionSalt` to decrypt the vault when password is not available.
   - Update `password` param in `fetchAllSeedPhrases` method to optional. If password is not provided, `cached EncryptionKey` will be used.
+- Password sync features implementation. ([#5877](https://github.com/MetaMask/core/pull/5877))
+  - checkIsPasswordOutdated to check current password is outdated compare to global password
+  - Add password outdated check to add SRPs / change password
+  - recover old password using latest global password
+  - sync latest global password to reset vault to use latest password and persist latest auth pubkey

Subject: [PATCH 0453/1148] fix(accounts-controller): fix Snap account's
 metadata update when Snaps during wallet reset flow (#5884)

## Explanation

We assume the `snap` will always be defined, but they could be
deleted/reloaded during some flows. To prevent using an `undefined`
`snap` here, we check if it's defined first, if not, we consider it to
be disabled.

 ### Fixed
 
+- Prevent use of `undefined` Snap during `SnapController:stateChange` ([#5884](https://github.com/MetaMask/core/pull/5884))
+  - We were assuming that the Snap will always be defined, but this might not always be true.
 - Populate `.options.entropySource` for new `InternalAccount`s before publishing `:accountAdded` ([#5841](https://github.com/MetaMask/core/pull/5841))

Subject: [PATCH 0454/1148] Release 416.0.0 (#5885)

## Explanation

Include `accounts-controller` bug fixes:

```ts
### Fixed

- Prevent use of `undefined` Snap during `SnapController:stateChange` ([#5884](https://github.com/MetaMask/core/pull/5884))
  - We were assuming that the Snap will always be defined, but this might not always be true.
- Populate `.options.entropySource` for new `InternalAccount`s before publishing `:accountAdded` ([#5841](https://github.com/MetaMask/core/pull/5841))
```

Subject: [PATCH 0458/1148] teams.json: Use correct label for Solana team
 (#5889)

The label that the Solana team is using in extension and mobile is
called `team-solana`, not `team-sol`. Because of this discrepancy, the
`create-update-issues` GitHub workflow currently errors out. This commit
corrects the label so the workflow will function again.

Subject: [PATCH 0459/1148] feat: update `toprf-secure-backup` sdk to `0.3.0`
 (#5880)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
- updated `@metamask/toprf-secure-backup` sdk to `0.3.0`.
- added optional constructor arg `toprfKeyDeriver` to assist the
`keyDerivation` in `toprf-secure-backup` sdk
- updated the use of `GroupedAuthConnectionConfig` to enforce the
correct implementation and align with w3a docs.
- cached recovery error data in the state
- correctly extract `RatelimitErrorData` from the recovery request and
synchorize the `RecoveryErrorData` across multiple devices

Subject: [PATCH 0460/1148] chore: explicitly pass networkClientId for
 nftController (#5622)

## Explanation

This PR is part of a larger effort to remove the global network
selector.

On this PR:
* Removal of this.#chainId on the nftController
* Removal of chainId from nftController constructor
* Making the optional networkClientId in all functions a mandatory field

UI integration:
- extension: https://github.com/MetaMask/metamask-extension/pull/31917

### `@metamask/assets-controllers`

- **UPDATE:** Updated `NftController` and `NftDetectionController` to
eliminate the dependency on the current chain. All functions that
previously accepted networkClientId as an optional parameter now require
it as a mandatory parameter

## Checklist

- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),

Subject: [PATCH 0463/1148] fix: include gas in simulation requests (#5754)

## Explanation

Include gas limit and gas fees in balance change simulation requests.

Specifically:

- Create alternate simulation request specifically for gas fee tokens in
new `utils/gas-fee-tokens.ts`.
- Rename `utils/simulation.ts` to `utils/balance-changes.ts`.
- Add `withGas` and `withDefaultBlockOverrides` to balance change
simulation requests.
- Override balance in balance change requests if insufficient balance.
- Subtract gas cost from native balance change.
- Replace code override with `authorizationList` including `from`
property.
- Retrieve MetaMask fee from simulation API.

Subject: [PATCH 0465/1148] chore: bump `@metamask/create-release-branch` to
 `^4.1.3` (#5897)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR bumps `@metamask/create-release-branch` to `^4.1.3`
([CHANGELOG](https://github.com/MetaMask/create-release-branch/blob/main/CHANGELOG.md#413)),
with the below improvement:

- When creating a new release and populating the Unreleased section, use
the same repo URLs in PR links as `auto-changelog update` would use.
- This prevents the updated changelog that `create-release-branch`
produces from being invalid in the case where a non-standard URL was
used to clone the repo originally.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Changelog

<!--
THIS SECTION IS NO LONGER NEEDED.

The process for updating changelogs has changed. Please consult the
"Updating changelogs" section of the Contributing doc for more.

Subject: [PATCH 0467/1148] feat: add lending functionality to controller
 (#5828)

## Explanation

* What is the current state of things and why does it need to change?
- Currently we do not have lending functionality in the earn controller.
We want to be able to control pooled staking and lending from one source
such that we can extend to extension easily
* What is the solution your changes offer and how does it work?
- updates earn sdk to latest
- adds lending api methods and helpers
- adds lending contract methods and helpers
- adds multichain for pooled staking state
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* No I don't think so
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* - n/a
* If you had to upgrade a dependency, why did you do so?
- We need the latest stake-sdk to use lending functionality

Subject: [PATCH 0468/1148] fix: remove error_message from QuotesRequested
 event properties (#5900)

## Explanation

`error_message` is not part of the QuoteRequested event schema so it
needs to be removed from the event payload

 ### Added
 
-- Initial implementation of the seedless onboarding controller. ([#5874](https://github.com/MetaMask/core/pull/5874))
-  - Authenticate OAuth user using the seedless onboarding flow and determine if the user is already registered or not
-  - Create a new Toprf key and backup seed phrase
-  - Add a new seed phrase backup to the metadata store
-  - Add array of new seed phrase backups to the metadata store in batch (useful in multi-srp flow)
-  - Fetch seed phrase metadata from the metadata store
-  - Update the password of the seedless onboarding flow
-- Support multi SRP sync using social login. ([#5875](https://github.com/MetaMask/core/pull/5875))
-  - Update Metadata to support multiple types of secrets (SRP, PrivateKey).
-  - Add `Controller Lock` which will sync with `Keyring Lock`.
-  - Updated `VaultEncryptor` type in constructor args and is compulsory to provided relevant encryptor to constructor.
-  - Added new non-persisted states, `encryptionKey` and `encryptionSalt` to decrypt the vault when password is not available.
-  - Update `password` param in `fetchAllSeedPhrases` method to optional. If password is not provided, `cached EncryptionKey` will be used.
-- Password sync features implementation. ([#5877](https://github.com/MetaMask/core/pull/5877))
-  - checkIsPasswordOutdated to check current password is outdated compare to global password
-  - Add password outdated check to add SRPs / change password
-  - recover old password using latest global password
-  - sync latest global password to reset vault to use latest password and persist latest auth pubkey
-- Updated `toprf-secure-backup` to `0.3.1`. ([#5880](https://github.com/MetaMask/core/pull/5880))
-  - added an optional constructor param, `topfKeyDeriver` to assist the `Key derivation` in `toprf-seucre-backup` sdk and adds an additinal security
-  - added new state value, `recoveryRatelimitCache` to the controller to parse the `RecoveryError` correctly and synchroize the error data (numberOfAttempts) across multiple devices.
+- Initial release of the seedless onboarding controller ([#5874](https://github.com/MetaMask/core/pull/5874), [#5875](https://github.com/MetaMask/core/pull/5875), [#5880](https://github.com/MetaMask/core/pull/5880))
+  - This controller allows MM extension and mobile users to login with google, apple accounts. This controller communicates with web3auth nodes + relies on toprf sdk (unreleased) to perform CRU operations related to backing up srps.
+  - The controller contains the following methods:
+    - `authenticate`: Authenticate OAuth user, generate Valid Authentication Token to interact with TOPRF Services and determine if the user has already registered or not.
+    - `createToprfKeyAndBackupSeedPhrase`: Create a new TOPRF encryption key using given password, encrypt the Seed Phrase and store the encrypted data in the metadata store.
+    - `addNewSeedPhraseBackup`: Add and encrypt a new seed phrase backup to the metadata store without create a new TOPRF encryption key.
+    - `fetchAllSeedPhrases`: Retrieve the encrypted backed-up Seed Phrases from the metadatastore and return decrypted Seed Phrases.
+    - `changePassword`: Update the password of the seedless onboarding flow
+    - `updateBackupMetadataState`: Update the backup metadata state of the controller.
+    - `verifyVaultPassword`: Verify the password validity by decrypting the vault
+    - `getSeedPhraseBackupHash`: Get the hash of the seed phrase backup for the given seed phrase from the state.
+    - `submitPassword`: Validate a password and unlock the controller.
+    - `setLocked`: Remove secrets from state and set the controller status to locked.
+    - `syncLatestGlobalPassword`: Sync the latest global password to the controller. This is useful for syncing the password change update across multiple devices.
+    - `recoverCurrentDevicePassword`:
+      - Recover the vault which is encrypted with the outdated password with the new password.
+      - This is useful when user wants to sync the current device without logging out.
+      - e.g. User enters the new password, decrypts the current vault (which was initially encrypted with old password) using the new password and recover the Key data.
+    - `checkIsPasswordOutdated`: Check if the password is current device is outdated, i.e. user changed password in another device.
+    - `clearState`: Reset the state of the controller to the defaults.

Subject: [PATCH 0470/1148] feat(backup & sync): use entropySourceId to sync
 accounts for Multi-SRP (#5753)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This is a first pass at syncing account data for each SRP.
This PR adds an optional `entropySourceId` param to all methods that
might use it, and then uses it for account-syncing.

Following #5618 we have extra `options` available on `InternalAccount`
objects; `entropySource` and `derivationPath`.
We can use these to properly segregate account data for multi-SRP.

This PR does not introduce breaking changes to the API, but to be able
to get the benefits we still need the clients to cooperate, so some
changes are needed there too.

* Proposal for a later PR: it might be easier to replace the spray of
`entropySourceId` params in the user-storage sdk/controller with
multiple `this.config.auth` instances, or something along those lines.
* the SRP JWT bearer authenticator can have multiple instances; each
instance could use a class member `entropySourceId` instead of needing
an update to all method params
* the Auth controller is a singleton, this means its methods will need
to accept `entropySourceId` parameters
* not sure yet if these can be reconciled; perhaps the controller can
maintain multiple instances of the SDK authenticators
	* will solve these in later passes

---

Subject: [PATCH 0471/1148] Adds estimate gas limit for transaction batch using
 simulation API (#5852)

## Explanation

This PR adds `simulateGasBatch` support to the Transaction Controller,
enabling sequential gas estimation for `nestedTransactions` within a
batch. When both `useHook` and `requireApproval` are `true`, the method
simulates each transaction, calculates the total and individual gas
limits, and stores the result in state for further use in the UI or
execution logic.

## Changes

### Transaction Controller
- Added `simulateGasBatch` to estimate gas for each transaction in a
batch sequentially.
- Integrated `simulateGasBatch` into the `addTransactionBatch` flow,
triggered when `useHook` and `requireApproval` are `true`.
- Extended state to store total gas limits from simulation.
- Updated unit tests to cover batch and gas simulation logic.

Subject: [PATCH 0472/1148] Release/421.0.0 (#5901)

## Explanation

* What is the current state of things and why does it need to change?

Currently we need to release a new version of the earn-controller so
that clients can consume the new lending functionality

* What is the solution your changes offer and how does it work?

This is a release of `@metamask/earn-controller@1.0.0` that can be
consumed by clients to get lending functionality

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Subject: [PATCH 0476/1148] feat: add `@metamask/foundryup` package (#5810)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR introduces a JavaScript-based foundryup installer that
simplifies the installation of Foundry toolchain binaries—Anvil, Cast,
Forge, and Chisel. The installer is designed to be cross-platform and
work across macOS, Linux, and Windows, supporting both ARM and AMD
architectures.

It's been used in the MetaMask Extension for a few months now:
https://github.com/MetaMask/metamask-extension/pull/28393

+# `@metamask/foundryup`
+
+foundryup
+
+## Installation
+
+`yarn add @metamask/foundryup`
+
+or
+
+`npm install @metamask/foundryup`
+
+## Usage
+
+Once installed into a package you can do `yarn bin mm-foundryup`.
+
+This will install the latest version of Foundry things by default.
+
+Try `yarn bin mm-foundryup --help` for more options.
+
+Once you have the binaries installed, you have to figure out how to get to them.
+
+Probably best to just add each as a `package.json` script:
+
+```json
+"scripts": {
+  "anvil": "node_modules/.bin/anvil",
+}
+```
+
+Kind of weird, but it seems to work okay. You can probably use `npx anvil` in place of `node_modules/.bin/anvil`, but
+getting it to work in all scenarios (cross platform and in CI) wasn't straightforward. `yarn bin anvil` doesn't work
+in yarn v4 because it isn't a bin of `@metamask/foundryup`, so yarn pretends it doesn't exist.
+
+This all needs to work.
+
+---
+
+You can try it here in the monorepo by running `yarn workspace @metamask/foundryup anvil`.

Subject: [PATCH 0477/1148] Release/423.0.0 (#5907)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

The foundryup package is a cross-platform tool used to manage Foundry
binaries in MetaMask’s development and end-to-end testing environments.
Its main goal is to simplify the installation and usage of foundry and
anvil across different operating systems and development setups at
MetaMask.

#### Why This Change?

The current setup for managing Foundry binaries is not tailored to
MetaMask’s specific needs. The upstream foundryup script is designed for
general CLI usage and doesn't offer the right defaults or integration
points required by our development workflows. This new package addresses
that gap by providing a consistent, customizable way to install and
manage Foundry tooling.

#### How It Works

This package acts as a wrapper around Foundry’s distribution, setting
defaults that make it easier to use within MetaMask projects. While it’s
primarily for CLI use (not programmatic use cases), it could eventually
replace ganache for many developers working on MetaMask.

Key features include:
- Binary caching: Binaries can be stored either locally or globally
depending on the Yarn configuration.
- Cross-platform support: Compatible with macOS, Linux, and Windows.
- Integrity verification: Checksums are used to verify binary integrity.
- Efficient binary linking: Symlinks are created when possible;
otherwise, binaries are copied.
- Workflow integration: Binaries are installed to node_modules/.bin,
making them easy to use in scripts and tooling.

Subject: [PATCH 0479/1148] Release/423.0.0 (#5909)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

The foundryup package is a cross-platform tool used to manage Foundry
binaries in MetaMask’s development and end-to-end testing environments.
Its main goal is to simplify the installation and usage of foundry and
anvil across different operating systems and development setups at
MetaMask.

#### Why This Change?

The current setup for managing Foundry binaries is not tailored to
MetaMask’s specific needs. The upstream foundryup script is designed for
general CLI usage and doesn't offer the right defaults or integration
points required by our development workflows. This new package addresses
that gap by providing a consistent, customizable way to install and
manage Foundry tooling.

#### How It Works

This package acts as a wrapper around Foundry’s distribution, setting
defaults that make it easier to use within MetaMask projects. While it’s
primarily for CLI use (not programmatic use cases), it could eventually
replace ganache for many developers working on MetaMask.

Key features include:
- Binary caching: Binaries can be stored either locally or globally
depending on the Yarn configuration.
- Cross-platform support: Compatible with macOS, Linux, and Windows.
- Integrity verification: Checksums are used to verify binary integrity.
- Efficient binary linking: Symlinks are created when possible;
otherwise, binaries are copied.
- Workflow integration: Binaries are installed to node_modules/.bin,
making them easy to use in scripts and tooling.

Subject: [PATCH 0480/1148] fix: fail gracefully when L1 gas fees are not
 available (#5910)

## Explanation

This fixes L1 and Solana fee calculations in the BridgeController such
that some quotes can be returned if exceptions are thrown by
dependencies (snap and RPCs).

Subject: [PATCH 0485/1148] feat: Default addTransactionBatch to EIP7702 if
 supported, otherwise use sequential batch (#5853)

## Explanation

We previously relied on the `useHook` property in the request. Instead,
the deciding factor is only whether or not EIP 7702 is supported on the
chain of the batch transaction.

Subject: [PATCH 0494/1148] fix: Avoid coercing publishBatchHook to a boolean
 (#5934)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

With the previous syntax, publishBatchHook would be coerced into a
boolean, which would halt execution further down the function when it is
awaited. This PR fixes normal function execution by avoiding coercion.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

Subject: [PATCH 0500/1148] fix/account-tracker-prevent-empty-state-update
 (#5942)

## Explanation

This change prevents AccountTrackerController from overwriting cached
balances with empty or unchanged state during refresh operations.

Currently, if all balance requests for a chain fail or return undefined
(e.g., due to a temporary network issue), the controller updates the
state with an empty object, erasing previous data. Additionally, even
when the new balance data is identical to the current state, an update
is still triggered, resulting in unnecessary stateChange emissions and
potential UI re-renders.

This update introduces guards within the refresh method to:

- Skip updates if the computed accountsForChain object is empty.
- Skip updates if the resulting balances are identical to the current
state.
- Prevent stale or partial data from overriding valid cached values.
- Reduce unnecessary re-renders and state emissions.

These changes help improve performance and stability, particularly under
poor network conditions or when balance polling is frequent.

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

### `@metamask/assets-controllers`

UPDATE: Prevent AccountTrackerController from updating state with empty
or unchanged data during balance refresh. Adds checks to avoid
overwriting valid cached balances and reduce unnecessary stateChange
emissions.

Subject: [PATCH 0501/1148] feat: add getErc20Balances helper
 TokenBalancesControllers (#5925)

## Explanation

This change introduces a new `getErc20Balances` service function within
the `TokenBalancesController`. The goal is to provide a reusable and
isolated utility to fetch ERC-20 token balances for a given address and
token list.

The service is intended to be used internally by the controller or other
consumers needing direct access to raw ERC-20 balances, while
abstracting away Web3 calls and error handling.

## Changelog

### `@metamask/assets-controllers`

UPDATE: Created getErc20Balances function within TokenBalancesController
to support fetching ERC-20 token balances for a given address and token
list. This modular service simplifies balance retrieval logic and can be
reused across different parts of the controller.

-->
Added `Private Key` sync feature to the `SeedlessOnboardingController`.
- `PrivateKey` will be encrypted and added to the metadata store
(similar to the `SRP backups`)
- Upon rehydration, both `Mnemonics` (Seed phrases) and `Private Keys`
will be decrypted and returned in bytes.

Subject: [PATCH 0503/1148] feat: add `EventQueue` class util to guarantee the
 order of user-storage updates (#5937)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR add a new `EventQueue` shared class util to the
`@metamask/profile-sync-controller` package.
We are using this to ensure user-storage updates are executed and
fulfilled in the actual order they were called.
For now, this is used for account syncing when reacting to
`AccountsController` `accountRenamed` and `accountAdded` events.

This addition has been made in reaction to a recent change to extension
code that made it so that when a user adds a new account, without
changing the default name, both `accountAdded` and `accountRenamed` were
fired.
This induced race conditions where we weren't in control of which
user-storage request would land first.
With this change, we raise back our confidence to 100%.

- ✅ Extension test drive PR:

+### Added
+
+- Add a new `EventQueue` class util that introduces two public methods, `push` and `run`
+  - Add an instance of `EventQueue` to `UserStorageController`
+  - Event subscriptions for `AccountsController:accountAdded` and `AccountsController:accountRenamed` are now pushing their callbacks to the `UserStorageController` instance of `EventQueue`, so that we stay in control of the order these callbacks are fulfilled.

Subject: [PATCH 0508/1148] Add `gasFeeEstimates` for batch transactions
 (#5886)

## Explanation

This PR enhances `TransactionBatchMeta` by adding support for
`gasFeeEstimates` and `status`.
When both `useHook` and `requireApproval` are `true`, the batch approval
flow is triggered, and `gasFeeEstimates` are populated using the
`DefaultGasFeeFlow`. These estimates are then passed along with the
request to be consumed by the client.

## Changes

- Extended `TransactionBatchMeta` to include:
  - `gasFeeEstimates`
  - `status`
- Introduced a new helper function: `prepareApprovalData`
  - Responsible for preparing approval data before creating the request

Subject: [PATCH 0516/1148] Fix type of
 `ErrorReportingService.captureException` option (#5968)

Currently, initializing ErrorReportingService with `captureException`
from `@sentry/react-native` on mobile produces a type error because the
`captureException` option doesn't match. (It also doesn't match the
`captureException` method/action, either.) This commit fixes that.

Subject: [PATCH 0517/1148] feat: after simulate and before sign hooks (#5503)

## Explanation

Support `afterSimulate` and `beforeSign` hooks, including optional
`updateTransaction` callbacks.

The `afterSimulate` hook can also return `skipSimulation` which will
disable subsequent balance change simulation.

Plus:

- Add optional `containerTypes` property to `TransactionMeta`.
- Add `TransactionControllerEstimateGasAction` messenger action.
- Add `ignoreDelegationSignatures` option to `estimateGas` method.
- Ignore `DelegationManager` signature errors in simulation requests.

## References

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've highlighted breaking changes using the "BREAKING" category
above as appropriate
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0518/1148] refactor: descriptive caip25CaveatBuilder
 unsupported scopes  (#5806)

## Explanation
Currently the exception thrown by `caip25CaveatBuilder` `validator`
doesn't reference the unsupported scopes that caused it. With this
change we list all the scopes that failed validation on the exception
message when throwing it.

Subject: [PATCH 0519/1148] chore: remove multichain deprecated package (#5960)

## Explanation

As follow-up work to the previous splitting of the `multichain` package
into 3 new packages

`@metamask/chain-agnostic-permission`
`@metamask/eip1193-permission-middleware`
`@multichain/multichain-api-middleware`

done in the [following PR](https://github.com/MetaMask/core/pull/5476),
we now want to completely deprecate/remove the legacy package and later
mark it as deprecated while also linking to the new packages in npm.

- * Handler for the `wallet_revokeSession` RPC method as specified by [CAIP-285](https://chainagnostic.org/CAIPs/caip-285).

- * and instead revokes the singular session for the origin if available. Additionally,
- * the handler also does not return an error if there is currently no active session and instead
- * returns true which is the same result returned if an active session was actually revoked.
- *
- * @param request - The JSON-RPC request object.
- * @param response - The JSON-RPC response object.

Add refresh token and revoke refresh token handling to
SeedlessOnboardingController

- persist refresh token in state
- store revoke token in vault
- check for token expired in toprf call, refresh token and retry
- revoke refresh token and replace with new one after password submit to
prevent malicious use if refresh token leak in persisted state

Subject: [PATCH 0523/1148] Check duplicates data before adding or creating new
 backup (#5955)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This PR adds a duplicate data check before user adds new `SecretData`
(Mnemonics or PrivateKey).
If the data is already existed in the controller backup state, we will
skip adding to the metadata store.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

 ### Added
 
-- Added `PrivateKey sync` feature to the controller. ([#5948](https://github.com/MetaMask/core/pull/5948))
-- **breaking** Updated controller methods signatures.
+- Added `PrivateKey sync` feature to the controller ([#5948](https://github.com/MetaMask/core/pull/5948)).
+  - **BREAKING** Updated controller methods signatures.
   - removed `addNewSeedPhraseBackup` and replaced with `addNewSecretData` method.
   - added `addNewSecretData` method implementation to support adding different secret data types.
   - renamed `fetchAllSeedPhrases` method to `fetchAllSecretData` and updated the return value to `Record<SecretType, Uint8Array[]>`.
   - added new error message, `MissingKeyringId` which will throw if no `keyringId` is provided during seed phrase (Mnemonic) backup.
+- Added a check for `duplicate data` before adding it to the metadata store. ([#5955](https://github.com/MetaMask/core/pull/5955))
+  - renamed `getSeedPhraseBackupHash` to `getSecretDataBackupState` and added optional param (`type`) to look for data with specific type in the controller backup state.
+  - updated `updateBackupMetadataState` method param with `{ keyringId?: string; data: Uint8Array; type: SecretType }`. Previously , `{ keyringId: string; seedPhrase: Uint8Array }`.

Subject: [PATCH 0524/1148] fix: prevent `TokenBalancesController` updating
 account balance to 0 while multicall contract failed (#5975)

## Explanation

This PR fix:
TokenBalancesController updating account balance to 0 while multicall
contract failed

in `AssetsControllers/TokenBalancesController` ->
`updateBalancesByChainId`
it use multicall contract to continually poll the balance and update the
balance for the account,
however even if the contract request failed, it will continue to update

the root cause is because the multicall return an array of
MulticallResult object even it failed, but the value of the balance may
become undefined

hence, the `updateBalancesByChainId` will continue using this value to
process the logic, and result update the balance to 0


Attached the extension screen that impacted by above logic

Subject: [PATCH 0525/1148] Removed `recoveryRatelimitCache` from the Seedless
 controller state (#5976)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had

* If you had to upgrade a dependency, why did you do so?
-->
This PR removes the `recoveryRatelimitCache` data from the controller
state.
Previously, the state was needed to address the state sync between
devices because of the inaccurate rate-limit blocking time from the
server. Recently, the fixes for this were addressed in the Server as
well as in the SDK, hence the state data are redundant and will not work
anymore.

Subject: [PATCH 0526/1148] use `approvalType.TransactionBatch` (#5971)

## Explanation
This PR aims to change the hardcoded `transaction_batch` to use the
`ApprovalType.TransactionBatch` from Controller utils, and some cleanup
in unit tests.

Subject: [PATCH 0529/1148] fix: `isInternalAccountInPermittedAccountIds` case
 where only `wallet:eip155` permission exists for a given address (#5980)

## Explanation

We aren't handling the case where a permitted account with the
`wallet:eip155` scope prefix is passed into
`isInternalAccountInPermittedAccountIds` - where it is the only
representation of its address in the permission set. In this case we
wouldn't find a permitted account matching a passed in internal account
and would [ultimately throw an
error](https://github.com/MetaMask/metamask-mobile/blob/97486f7d2aff5d075865e93126727590c88c0c4d/app/core/Permissions/index.ts#L145)
resulting in the app crashing.

## References

* Fixes error [reported
here](https://consensys.slack.com/archives/C08UFPWB3GB/p1749821334454809)

## Changelog
### `@metamask/chain-agnostic-permission`
- Fix `isInternalAccountInPermittedAccountIds` and
`isCaipAccountIdInPermittedAccountIds` to correctly handle comparison
against `permittedAccounts` values of the `wallet:<namespace>:<address>`
format

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?

* If your primary goal was to update one package but you found you had

Removes uncategorized changelog entry from the bridge controller. This
entry was only for bumping a dev dependency, so doesn't need to remain
in the changelog.

Subject: [PATCH 0535/1148] feat!: scanUrl uses v2 endpoint (#5981)

## Explanation

> **NOTE:** This PR introduces a breaking change for any consumers using
`scanUrl` and should maintain using `12.x.x` until they have been
updated.

Currently the PhishingController uses the `/scan` endpoint for the
`scanUrl` function. This PR makes it use the `v2/scan` endpoint. One
change with the v2 endpoint is that it returns `hostname` instead of
`domainName`, which is more idiomatic.

Subject: [PATCH 0536/1148] feat(identity): sync address book contacts (#5776)

## Explanation

The current implementation of MetaMask's address book (contacts) lacks
the ability to synchronize between devices. While we recently
implemented this capability for accounts using encrypted user storage,
the address book remained local to each device.
This PR implements backup-and-sync functionality for the address book
controller, similar to what was already implemented for the accounts
controller.

### Implementation notes
1. Creates a dedicated integration in the profile-sync-controller
package with:
- Type definitions for address book storage entries
- Conversion utilities between controller and storage formats
- Sync logic to handle bidirectional synchronization
2. Event subscriptions to trigger syncs on contact update/deletion
3. Updates the UserStorageController to properly handle address book
data

## References

Needed by: https://github.com/MetaMask/metamask-extension/pull/32632
Depends on: https://github.com/MetaMask/core/pull/5779

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0537/1148] feat: migrate notification endpoints to v2 (#5945)

## Explanation

Reduces the number of API calls by 25-33% (cut 1/4 - 1/3 endpoints).
Removes complex encryption and decryption logic from UserStorage. This
took at least 2s on mobile per request!
Enables us to have our notification backend to be the source of truth.
We can now extend notifications easily without as much front-end work.

Test Drive PRs:
- Extension: https://github.com/MetaMask/metamask-extension/pull/33564
- Mobile: https://github.com/MetaMask/metamask-mobile/pull/16360

 ## [Unreleased]
 
+### Added
+
+- SEI network to supported networks for notifications ([#5945](https://github.com/MetaMask/core/pull/5945))
+  - Added `SEI` to `NOTIFICATION_CHAINS_ID` constant
+  - Added `Sei Network` to default `NOTIFICATION_NETWORK_CURRENCY_NAME` constant
+  - Added `SEI` to default `NOTIFICATION_NETWORK_CURRENCY_SYMBOL` constant
+  - Added SEI block explorer to default `SUPPORTED_NOTIFICATION_BLOCK_EXPLORERS` constant
+
 ### Changed
 
+- **BREAKING:** Migrated to notification v2 endpoints ([#5945](https://github.com/MetaMask/core/pull/5945))
+
+  - `https://trigger.api.cx.metamask.io/api/v1` to `https://trigger.api.cx.metamask.io/api/v2` for managing out notification subscriptions
+  - `https://notification.api.cx.metamask.io/api/v1` to `https://notification.api.cx.metamask.io/api/v2` for fetching notifications (in-app notifications)
+  - `https://push.api.cx.metamask.io/v1` to `https://push.api.cx.metamask.io/v2` for subscribing push notifications
+  - Renamed method `updateOnChainTriggersByAccount` to `enableAccounts` in `NotificationServicesController`
+  - Renamed method `deleteOnChainTriggersByAccount` to `disableAccounts` in `NotificationServicesController`
+  - Deprecated `updateTriggerPushNotifications` from `NotificationServicesPushController` and will be removed in a subsequent release.
+
 - Bump `@metamask/controller-utils` to `^11.10.0` ([#5935](https://github.com/MetaMask/core/pull/5935))
 
+### Removed
+
+- **BREAKING:** Migrated to notification v2 endpoints ([#5945](https://github.com/MetaMask/core/pull/5945))
+
+  - removed `NotificationServicesPushController:updateTriggerPushNotifications` action from `NotificationServicesController`
+  - removed `UserStorageController:getStorageKey` action from `NotificationServicesController`
+  - removed `UserStorageController:performGetStorage` action from `NotificationServicesController`
+  - removed `UserStorageController:performSetStorage` action from `NotificationServicesController`
+  - removed UserStorage notification utilities: `initializeUserStorage`, `cleanUserStorage`, `traverseUserStorageTriggers`, `checkAccountsPresence`, `inferEnabledKinds`, `getUUIDsForAccount`, `getAllUUIDs`, `getUUIDsForKinds`, `getUUIDsForAccountByKinds`, `upsertAddressTriggers`, `upsertTriggerTypeTriggers`, `toggleUserStorageTriggerStatus`.

A previous commit that updated NetworkController to auto-correct
`selectedNetworkClientId` also made it so that the controller now
expects the client to initialize ErrorReportingService and its messenger
ahead of time (and for `ErrorReportingService:captureException` to be
added to NetworkControllerMessenger's allowlist). This fact was never
enforced properly, and it was never documented in the changelog.

This commit addresses this issue by moving
`@metamask/error-reporting-service` to `peerDependencies` and bringing
the changelog up to date.

Subject: [PATCH 0541/1148] chore: stop quote polling when tx submission has
 started (#5994)

## Explanation

This PR adds a stopPollingForQuotes handler to the bridge controller to
prevent quotes from refreshing during tx submission. This enables
"pausing" the quote polling loop without resetting the entire state.
Without this, it's possible for the activeQuote to change while the UI's
tx submission is in-progress

This only needs to be called from `submitTx` and doesn't need to be
explicitly called from the UI.

**For clients**: `stopPollingForQuotes` needs to be added to the
bridgeStatusController's allowed actions

Subject: [PATCH 0542/1148] fix case where internal accounts can be undefined
 (#6000)

## Explanation
Temporary fix for the issue where the internal account has no scopes and
or scopes is undefined
there is currently a bug where an account associated with a snap can
fail to add scopes to the internal account in time
before we attempt to access this state

## References

For example:

* Fixes https://github.com/MetaMask/metamask-extension/issues/32451
* [Sentry
Error](https://metamask.sentry.io/issues/6683351210/?project=273505)
* Slack thread:
https://consensys.slack.com/archives/C08T784K955/p1750172591818219


## Changelog

## @metamask/chain-agnostic-permission

*CHANGED*: `isInternalAccountInPermittedAccountIds` now returns false
when passed an `InternalAccount` where `scopes` is `undefined`

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

-- **BREAKING:** BridgeStatusController now requires the `BridgeController:stopPollingForQuotes` action permission ([#5994](https://github.com/MetaMask/core/pull/5994))
+## [31.0.0]
 
 ### Changed
 
-- **BREAKING:** Adds a call to bridge-controller's `stopPollingForQuotes` handler to prevent quotes from refreshing during tx submission. This enables "pausing" the quote polling loop without resetting the entire state. Without this, it's possible for the activeQuote to change while the UI's tx submission is in-progress ([#5994](https://github.com/MetaMask/core/pull/5994))

Subject: [PATCH 0546/1148] Recategorize "internal" RPC errors more accurately
 (#5923)

Currently, a large class of errors that occur while making a request to
an RPC endpoint through the NetworkController provider are reinterpreted
as JSON-RPC "internal" errors. This is inaccurate and makes debugging
confusing. This PR updates the JSON-RPC codes for the following cases:

- An invalid/unparseable JSON error is now represented by code -32700
(parse error) instead of -32603 (internal error)
- A 401 response is now represented by code -32006 (unauthorized)
instead of -32603 (internal error)
- A 405 response is now represented by code -32080 (client error)
instead of -32601 (method not found)
- A 402, 404, or 5xx response is now represented with code -32002
(resource unavailable error) instead of -32603 (internal error)
- A 4xx response besides 401, 402, 404, 405, or 429 is now represented
with code -32080 (client error) instead of -32603 (internal error)

This PR also makes the following changes:

- Requests to an RPC endpoint that returns a 502 response ("bad
gateway") will now be retried
- All JSON-RPC errors that represent 4xx and 5xx responses from RPC
endpoints now include the HTTP status code under `data.httpStatus`
- 3xx responses from RPC endpoints are no longer treated as errors
- Improve detection of partial JSON responses from RPC endpoints

Subject: [PATCH 0547/1148] feat: support incoming transaction polling only
 when viewing activity (#5986)

## Explanation

Support the clients polling incoming transactions only when viewing the
transaction activity list.

Specifically:

- Delete incoming transactions when calling `wipeTransactions` method.
- Poll immediately when calling `startIncomingTransactionPolling`
method.

Subject: [PATCH 0549/1148] refactor: rename adapters to operators (#6008)

## Explanation

The `@metamask/chain-agnostic-permission` package has a folder called
`adapters`. This is no longer really an accurate descriptor for them, so
we decided to rename them to `operators`.

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

## References

* Fixes: https://github.com/MetaMask/MetaMask-planning/issues/5114

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

+### Added
+
+- Add specific transaction types to outgoing transactions retrieved from accounts API ([#5987](https://github.com/MetaMask/core/pull/5987))
+  - Add optional `amount` property to `transferInformation` object in `TransactionMeta` type.
+
 ### Changed
 
 - Remove incoming transactions when calling `wipeTransactions` ([#5986](https://github.com/MetaMask/core/pull/5986))

Subject: [PATCH 0552/1148] fix: swap tx status events (#5993)

## Explanation

This fixes the following Unified SwapBridge events to match the Unified
SwapBridge spec
- **Completed**: removes multichain tx controller subscription and emits
the event based on the tx submission status instead
- **Submitted**
- set `swap` type for evm txs when applicable. this is currently
hardcoded to `bridge` so swaps don't get displayed correctly on the
activity list
- emit this event when submitTx is called, regardless of confirmation
status
- **Failed**
  - emit this when an error is thrown during solana tx submission
- use activeQuote to populate quote properties if tx fails before being
confirmed on chain
- Negates the value of the `can_submit` property

 ## [Unreleased]
 
+### Changed
+
+- Remove `@metamask/multichain-transactions-controller` peer dependency ([#5993](https://github.com/MetaMask/core/pull/5993))
+
+### Fixed
+
+- Update the following events to match the Unified SwapBridge spec ([#5993](https://github.com/MetaMask/core/pull/5993))
+  - `Completed`: remove multichain tx controller subscription and emit the event based on the tx submission status instead
+  - `Failed`: emit event when an error is thrown during solana tx submission
+  - `Submitted`
+    - set swap type for evm txs when applicable. this is currently hardcoded to bridge so swaps don't get displayed correctly on the activity list
+    - emit this event when submitTx is called, regardless of confirmation status
+
 ## [31.0.0]
 
 ### Changed
 
+- **BREAKING:** Adds a call to bridge-controller's `stopPollingForQuotes` handler to prevent quotes from refreshing during tx submission. This enables "pausing" the quote polling loop without resetting the entire state. Without this, it's possible for the activeQuote to change while the UI's tx submission is in-progress ([#5994](https://github.com/MetaMask/core/pull/5994))
 - **BREAKING:** BridgeStatusController now requires the `BridgeController:stopPollingForQuotes` action permission ([#5994](https://github.com/MetaMask/core/pull/5994))
 - **BREAKING:** Bump peer dependency `@metamask/accounts-controller` to `^31.0.0` ([#5999](https://github.com/MetaMask/core/pull/5999))
 - **BREAKING:** Bump peer dependency `@metamask/bridge-controller` to `^33.0.0` ([#5999](https://github.com/MetaMask/core/pull/5999))

Subject: [PATCH 0555/1148] test(KeyringController): mock encryptor upgrade
 (#5943)

## Explanation

For testing envelope encryption
(https://github.com/MetaMask/core/pull/5940), we need a more versatile
mock encryptor. (I.e., one that can handle multiple ciphertexts at the
same time.)

Hence, here we upgrade the mock encryptor as a preparation for #5490.

Subject: [PATCH 0557/1148] feat(KeyringController): add `exportEncryptionKey`
 method to export vault key (#5984)

## Explanation

Keyring Controller:
* Add method `controller.exportEncryptionKey` to export vault key.
* Change method `controller.submitEncryptionKey` to have an optional
salt.
* If the salt is provided, the controller will check that it is
consistent with the locally stored salt.
  * If the salt is not provided, this check is omitted.
* Before, the salt was mandatory, but it might not be required in the
case of unlocking the vault during vault recovery.

This feature is relevant for resolving an audit finding with the
seedless onboarding controller.

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

## References

Previously, seedless onboarding was backing up the keyring password to
allow for vault recovery after a password change. Now we backup the
keyring encryption key.

See the [ADR](https://github.com/MetaMask/decisions/pull/85) for more
details.
This is part of the implementation of option 6.

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

-- Bump `@metamask/controller-utils` from `^11.4.2` to `^11.4.3` ([#4915](https://github.com/MetaMask/core/pull/4915))
-
-### Removed
-
-- **BREAKING:** `createQueuedRequestMiddleware` no longer takes a `useRequestQueue` parameter. All requests are now queued if `shouldEnqueueRequest(req)` returns true. ([#4941](https://github.com/MetaMask/core/pull/4941))
-
-## [7.0.1]
-
-### Fixed
-
-- Fix issue where `queuedRequestCount` state is not updated after flushing requests for an origin ([#4898](https://github.com/MetaMask/core/pull/4898))
-
-## [7.0.0]
-
-### Added
-
-- **BREAKING:** The `QueuedRequestController` now requires the `canRequestSwitchNetworkWithoutApproval` callback in its constructor params. ([#4846](https://github.com/MetaMask/core/pull/4846))
-
-### Changed
-
-- The `QueuedRequestController` now ensures that a request that can switch the globally selected network without approval is queued behind any existing pending requests. ([#4846](https://github.com/MetaMask/core/pull/4846))
-
-### Fixed
-
-- The `QueuedRequestController` now ensures that any queued requests for a origin are failed if a request that can switch the globally selected network without approval actually does change the globally selected network for that origin. ([#4846](https://github.com/MetaMask/core/pull/4846))
-
-## [6.0.0]
-
-### Changed
-
-- **BREAKING:** Bump `@metamask/network-controller` peer dependency from `^21.0.0` to `^22.0.0` ([#4841](https://github.com/MetaMask/core/pull/4841))
-- Bump `@metamask/controller-utils` to `^11.4.0` ([#4834](https://github.com/MetaMask/core/pull/4834))

-
-## [5.1.0]
-
-### Changed
-
-- Batch processing now considers both origin and `networkClientId`, ensuring requests targeting different networks are processed separately. ([#4718](https://github.com/MetaMask/core/pull/4718))
-- Incoming requests to `enqueueRequest` now must include a `networkClientId`; an error is thrown if it's missing. This was previously a required part of the type but since consumers like the extension do not have extensive typescript coverage this wasn't definitively enforced. ([#4718](https://github.com/MetaMask/core/pull/4718))
-
-## [5.0.1]
-
-### Fixed
-
-- Produce and export ESM-compatible TypeScript type declaration files in addition to CommonJS-compatible declaration files ([#4648](https://github.com/MetaMask/core/pull/4648))
-  - Previously, this package shipped with only one variant of type declaration
-    files, and these files were only CommonJS-compatible, and the `exports`
-    field in `package.json` linked to these files. This is an anti-pattern and
-    was rightfully flagged by the
-    ["Are the Types Wrong?"](https://arethetypeswrong.github.io/) tool as
-    ["masquerading as CJS"](https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/FalseCJS.md).
-    All of the ATTW checks now pass.
-- Remove chunk files ([#4648](https://github.com/MetaMask/core/pull/4648)).
-  - Previously, the build tool we used to generate JavaScript files extracted
-    common code to "chunk" files. While this was intended to make this package
-    more tree-shakeable, it also made debugging more difficult for our
-    development teams. These chunk files are no longer present.
-- Remove extra slash when constructing user storage url ([#4702](https://github.com/MetaMask/core/pull/4702))

-
-## [1.0.0]
-
-### Changed
-
-- **BREAKING:** `QueuedRequestController` constructor no longer accepts the `methodsRequiringNetworkSwitch` array param. It's now replaced with the `shouldRequestSwitchNetwork` function param which should return true when a request requires the globally selected network to match that of the dapp from which the request originated. ([#4423](https://github.com/MetaMask/core/pull/4423))
-- **BREAKING:** `createQueuedRequestMiddleware` no longer accepts the `methodsWithConfirmation` array typed param. It's now replaced with the `shouldEnqueueRequest` function typed param which should return true when a request should be handled by the `QueuedRequestController`. ([#4423](https://github.com/MetaMask/core/pull/4423))

-
-## [0.8.0]
-
-### Added
-
-- **BREAKING**: The `QueuedRequestMiddleware` constructor now requires the `methodsWithConfirmation` param which should be a list of methods that can trigger confirmations ([#4066](https://github.com/MetaMask/core/pull/4066))
-- **BREAKING**: The `QueuedRequestController` constructor now requires the `methodsRequiringNetworkSwitch` param which should be a list of methods that need the globally selected network to switched to the dapp selected network before being processed ([#4066](https://github.com/MetaMask/core/pull/4066))
-- **BREAKING**: Clear pending confirmations (for both queued and non-queued requests) after processing revokePermissions. We now require a function to be passed into the constructor (`clearPendingConfirmations`) which will be called when permissions are revoked for a domain who currently has pending confirmations that are not queued. This is done by piggybacking on `SelectedNetworkController:stateChange` in order to serve as a proxy for permissions being revoked. ([#4165](https://github.com/MetaMask/controllers/pull/4165))
-- **BREAKING**: The QueuedRequestController will now flush the RequestQueue after a dapp switches networks. QueuedRequestController now requires a subscription on `SelectedNetworkController:stateChange`, and upon receiving stateChanges for adding or replacing selectedNetworkController.state.domains, we flush the queue for the domain in question. ([#4139](https://github.com/MetaMask/controllers/pull/4139))
-
-### Changed
-
-- **BREAKING**: `QueuedRequestController.enqueueRequest()` now ensures the globally selected network matches the dapp selected network before processing methods listed in the `methodsRequiringNetworkSwitch` constructor param. This replaces the previous behavior of switching for all methods except `eth_requestAccounts`. ([#4066](https://github.com/MetaMask/core/pull/4066))
-
-## [0.7.0]

-## [0.6.1]
-

-- Fix `types` field in `package.json` ([#4047](https://github.com/MetaMask/core/pull/4047))
-
-## [0.6.0]
-
-### Added
-
-- **BREAKING**: Add ESM build ([#3998](https://github.com/MetaMask/core/pull/3998))
-  - It's no longer possible to import files from `./dist` directly.
-- Export `QueuedRequestControllerGetStateAction` and `QueuedRequestControllerStateChangeEvent` ([#3984](https://github.com/MetaMask/core/pull/3984))
-
-### Changed
-
-- **BREAKING**: The `QueuedRequestController` will now batch queued requests by origin ([#3781](https://github.com/MetaMask/core/pull/3781), [#4038](https://github.com/MetaMask/core/pull/4038))
-  - All of the requests in a single batch will be processed in parallel.
-  - Requests get processed in order of insertion, even across origins/batches.
-  - All requests get processed even in the event of preceding requests failing.
-- **BREAKING:** The `queuedRequestCount` state no longer includes requests that are currently being processed; it just counts requests that are queued ([#3781](https://github.com/MetaMask/core/pull/3781))
-- **BREAKING:** The `QueuedRequestController` no longer triggers a confirmation when a network switch is needed ([#3781](https://github.com/MetaMask/core/pull/3781))
-  - The network switch now happens automatically, with no confirmation.
-  - A new `QueuedRequestController:networkSwitched` event has been added to communicate when this has happened.
-  - The `QueuedRequestController` messenger no longer needs access to the actions `NetworkController:getNetworkConfigurationByNetworkClientId` and `ApprovalController:addRequest`.
-  - The package `@metamask/approval-controller` has been completely removed as a dependency
-- **BREAKING:** The `QueuedRequestController` method `enqueueRequest` is now responsible for switching the network before processing a request, rather than the `QueuedRequestMiddleware` ([#3968](https://github.com/MetaMask/core/pull/3968))
-  - Functionally the behavior is the same: before processing each request, we compare the request network client with the current selected network client, and we switch the current selected network client if necessary.
-  - The `QueuedRequestController` messenger now requires four additional allowed actions:
-    - `NetworkController:getState`
-    - `NetworkController:setActiveNetwork`
-    - `NetworkController:getNetworkConfigurationByNetworkClientId`
-    - `ApprovalController:addRequest`
-  - The `QueuedRequestController` method `enqueueRequest` now takes one additional parameter, the request object.
-  - `createQueuedRequestMiddleware` no longer takes a controller messenger; instead it takes the `enqueueRequest` method from `QueuedRequestController` as a parameter.
-- **BREAKING**: Remove the `QueuedRequestController:countChanged` event ([#3985](https://github.com/MetaMask/core/pull/3985))
-  - The number of queued requests is now tracked in controller state, as the `queuedRequestCount` property. Use the `QueuedRequestController:stateChange` event to be notified of count changes instead.
-- **BREAKING**: Remove the `length` method ([#3985](https://github.com/MetaMask/core/pull/3985))
-  - The number of queued requests is now tracked in controller state, as the `queuedRequestCount` property.
-- **BREAKING:** Bump `@metamask/base-controller` to `^5.0.0` ([#4039](https://github.com/MetaMask/core/pull/4039))
-  - This version has a number of breaking changes. See the changelog for more.

-### Changed
-
-- **BREAKING:** Bump `@metamask/base-controller` to ^4.0.0 ([#2063](https://github.com/MetaMask/core/pull/2063))
-  - This is breaking because the type of the `messenger` has backward-incompatible changes. See the changelog for this package for more.

-- Bump @metamask/utils from 8.1.0 to 8.2.0 ([#1957](https://github.com/MetaMask/core/pull/1957))
-
-### Fixed
-
-- Fixes an issue in the extension when 'useRequestQueue' is enabled. The problem occurred when a DApp's selected network differed from the globally selected network, and when the DApp's chosen network was not a built-in network. Under these conditions, the nickname would not be displayed in the 'toNetworkConfiguration' parameter passed to the `addApproval` function ([#2000](https://github.com/MetaMask/core/pull/2000)).
-- Fixes an issue in the extension when 'useRequestQueue' is activated. Previously, when invoking 'wallet_addEthereumChain', if the DApp's selected network was different from the globally selected network, the user was incorrectly prompted to switch the Ethereum chain prior to the 'addEthereumChain' request. With this update, 'addEthereumChain' will still be queued (due to its confirmation requirement), but the unnecessary chain switch prompt has been eliminated ([#2000](https://github.com/MetaMask/core/pull/2000)).
-
-## [0.1.2]
-
-### Fixed
-
-- Fix issue where switching chain would ultimately fail due to the wrong `networkClientId` / `type` ([#1962](https://github.com/MetaMask/core/pull/1962))

-# `@metamask/queued-request-controller`
-
-Includes a controller and middleware that implements a request queue. A request queue allows for intelligently switching of the globally selected network based on the dapps selected network. It ultimately allows us to handle requests with an intended destination network that is different than the currently selected network.
-
-## Installation
-
-`yarn add @metamask/queued-request-controller`
-
-or

Subject: [PATCH 0563/1148] feat: fallback to node with overrides for type-4
 gas estimation (#6016)

## Explanation

Currently, gas estimations for type-4 transactions with `data` are done
using the simulation API only.

This adds a fallback to use `eth_estimateGas` with state overrides if
the simulation fails, due to the chain not being supported for example.

Subject: [PATCH 0565/1148] Extends `GasFeePoller` to update gas properties for
 unapproved transaction batches (#5950)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->
This PR extends the `GasFeePoller` to track/update gas properties for
unapproved `transactionBatches`.

## Changes

The GasFeePoller now:

- Detects unapproved `transactionBatches` via
`#getUnapprovedTransactionBatches`.
- Fetches gas estimates using `DefaultGasFeeFlow`.
- Emits `transaction-batch-updated` events with updated
`gasFeeEstimates`.

Updates are applied to the `TransactionBatchMeta` for each batch,
mirroring the behaviour already in place for single transactions.
This enhancement ensures that unapproved transaction batches receive
timely gas updates similar to individual transactions, improving
consistency across transaction types.

Fixes https://github.com/MetaMask/MetaMask-planning/issues/5090

Subject: [PATCH 0567/1148] Seedless controller: store keyring encryption key
 instead of password (#5995)

## Explanation

It has been discussed that the seedless controller should no longer
store and recover the vault password, instead it should store and
recover the vault encryption key for the purpose of vault recovery in
case of a global password change.

**Breaking**
- Added `submitGlobalPassword`, `storeKeyringEncryptionKey`, and
`loadKeyringEncryptionKey`.
- Changed `syncLatestGlobalPassword`.
- Removed `recoverCurrentDevicePassword`.

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

## References

Previously, seedless onboarding was backing up the keyring password to
allow for vault recovery after a password change. Now we backup the
keyring encryption key.

See the [ADR](https://github.com/MetaMask/decisions/pull/85) for more
details.
This is part of the implementation of option 6.

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

Subject: [PATCH 0570/1148] Reduce default circuit break duration to 2 minutes
 (#6015)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, the "circuit break duration" — the duration for which
requests to an RPC endpoint are paused when the endpoint is perceived to
be unavailable — is 30 minutes. This is a good value when a true outage
exists, but if the endpoint is merely degraded or is returning 500s for
specific requests then we don't want to lock users out of their wallet
for a long time. To accommodate these cases, this commit reduces the
circuit break duration to 2 minutes so that recovery is faster.

Subject: [PATCH 0571/1148] fix: update gasLimit to be passed as Hex string or
 undefined (#6038)

## Explanation



* What is the current state of things and why does it need to change?
- Currently we incorrectly pass gasLimit as a stringified number when
the addTransaction method expects a hex string
- Currently the Transactions controller allows gasLimit to be undefined,
passing the gas estimation task to the Transaction controller, we want
to utilize this ability in the future

* What is the solution your changes offer and how does it work?
- For any contract method that uses a gasLimit, allow
gasOptions.gasLimit to be set to 'none' and translate that to setting
gasLimit undefined in addTransaction params
- In the case that there is a gasLimit convert it to Hex string

* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
- Yes. The stake-sdk contract methods take gasLimit params such that gas
can be estimated if needed. The params allow gas to be set to none, but
that equates to 0 gas. We do not need to typically send 0 gas in our
cases. We can instead say that if one passes gasLimit none, in the earn
controller it means that they want to set addTransaction gasLimit to
undefined which will pass the task to Transaction Controller

Subject: [PATCH 0572/1148] chore: add gasIncluded to QuoteRequest and validate
 gas-included response fields (#6030)

## Explanation

Changes
- Add `gasIncluded` parameter to the bridge-api getQuote request
- clients should set this to a boolean indicating stx opt-in and network
support. same value as the stx boolean sent to `submitTx`
- Validate new response fields (`txFees`) and consolidate validator
structs + types
- Add `includedTxFees` to quote metadata
  - clients will display this as the "included fee"
- Small fix for calculating EVM token exchange rates

 ## [Unreleased]
 
+### Added
+
+- **BREAKING** Add a required `gasIncluded` quote request parameter to indicate whether the bridge-api should return gasless swap quotes. The clients need to pass in a Boolean value indicating whether the user is opted in to STX and if their current network has STX support ([#6030](https://github.com/MetaMask/core/pull/6030))
+- Add `gasIncluded` to QuoteResponse, which indicates whether the quote includes tx fees (gas-less) ([#6030](https://github.com/MetaMask/core/pull/6030))
+- Add `feeData.txFees` to QuoteResponse, which contains data about tx fees taken from either the source or destination asset ([#6030](https://github.com/MetaMask/core/pull/6030))
+- Add `includedTxFees` to QuoteMetadata, which clients can display as the included tx fee when displaying a gasless quote ([#6030](https://github.com/MetaMask/core/pull/6030))
+
+### Changed
+
+- Consolidate validator and type definitions for `QuoteResponse`, `BridgeAsset` and `PlatformConfigSchema` so new response fields only need to be defined once ([#6030](https://github.com/MetaMask/core/pull/6030))
+
+### Fixed
+
+- Calculate EVM token exchange rates accurately in `selectExchangeRateByChainIdAndAddress` when the `marketData` conversion rate is in the native currency ([#6030](https://github.com/MetaMask/core/pull/6030))
+

+- Clean up unused exports that duplicate @metamask/bridge-controller's ([#6030](https://github.com/MetaMask/core/pull/6030))
+  - Asset
+  - SrcChainStatus
+  - DestChainStatus
+  - RefuelData
+  - FeeType
+  - ActionTypes

 - **BREAKING** Add a required `gasIncluded` quote request parameter to indicate whether the bridge-api should return gasless swap quotes. The clients need to pass in a Boolean value indicating whether the user is opted in to STX and if their current network has STX support ([#6030](https://github.com/MetaMask/core/pull/6030))
 - Add `gasIncluded` to QuoteResponse, which indicates whether the quote includes tx fees (gas-less) ([#6030](https://github.com/MetaMask/core/pull/6030))
 - Add `feeData.txFees` to QuoteResponse, which contains data about tx fees taken from either the source or destination asset ([#6030](https://github.com/MetaMask/core/pull/6030))
-- Add `includedTxFees` to QuoteMetadata, which clients can display as the included tx fee when displaying a gasless quote ([#6030](https://github.com/MetaMask/core/pull/6030))
+- Add `includedTxFees` to QuoteMetadata, which clients can display as the included tx fee when displaying a gasless quote ([#6039](https://github.com/MetaMask/core/pull/6039))
+- Calculate and return value of `includedTxFees` ([#6039](https://github.com/MetaMask/core/pull/6039))
 
 ### Changed
 
 - Consolidate validator and type definitions for `QuoteResponse`, `BridgeAsset` and `PlatformConfigSchema` so new response fields only need to be defined once ([#6030](https://github.com/MetaMask/core/pull/6030))
+- Add `txFees` to total sentAmount ([#6039](https://github.com/MetaMask/core/pull/6039))
+- When gas is included and is taken from the destination token amount, ignore network fees in `adjustedReturn` calculation ([#6039](https://github.com/MetaMask/core/pull/6039))
 
 ### Fixed
 
 - Calculate EVM token exchange rates accurately in `selectExchangeRateByChainIdAndAddress` when the `marketData` conversion rate is in the native currency ([#6030](https://github.com/MetaMask/core/pull/6030))
+- Convert `trade.value` to decimal when calculating relayer fee ([#6039](https://github.com/MetaMask/core/pull/6039))

+# Data Services
+
+## What is a data service?
+
+A **data service** is a pattern for making interactions with an external API (fetching token prices, storing accounts, etc.). It is implemented as a plain TypeScript class with methods that are exposed through the messaging system.
+
+## Why use this pattern?
+
+If you want to talk to an API, it might be tempting to define a method in the controller or a function in a separate file. However, implementing the data service pattern is advantageous for the following reasons:
+
+1. The pattern provides an abstraction that allows for implementing and reusing strategies that are common when working with external APIs, such as batching, automatic retries with exponential backoff, etc.
+2. By integrating with the messaging system, other parts of the application can make use of the data service without needing to go through the controller, or in fact, without needing a reference to the data service at all.
+
+## How to create a data service
+
+Let's say that we want to make a data service that uses an API to retrieve gas prices. Here are the steps we'll follow:
+
+1. We will define a class which has a single method. (Data service classes can have more than one method, but we will keep things simple for now.)
+1. We will have our class take a messenger and a `fetch` function.
+1. We will define a type for the messenger, exposing the method as an action.
+
+### Implementation file
+
+We'll start by making a new file in the `src/` directory, `gas-prices-service.ts`, and here we will define the data service class. We'll have the constructor take two arguments:
+
+- A messenger (which we'll define below).
+- A `fetch` function. This is useful so that we don't have to rely on a particular JavaScript runtime or environment where a global `fetch` function may not exist (or may be accessible using a different syntax).
+
+```typescript
+export class GasPricesService {
+  readonly #messenger: GasPricesServiceMessenger;
+
+  readonly #fetch: typeof fetch;
+
+  constructor({
+    messenger,
+    fetch: fetchFunction,
+  }: {
+    messenger: GasPricesServiceMessenger;
+    fetch: typeof fetch;
+  }) {
+    this.#messenger = messenger;
+    this.#fetch = fetchFunction;
+  }
+}
+```
+
+We'll also add the single method that we mentioned above, using the given `fetch` option to make the request:
+
+```typescript
+// (top of file)
+
+type GasPricesResponse = {
+  data: {
+    low: number;
+    average: number;
+    high: number;
+  };
+};
+
+const API_BASE_URL = 'https://example.com/gas-prices';
+
+export class GasPricesService {
+  // ...
+
+  async fetchGasPrices(chainId: Hex): Promise<GasPricesResponse> {
+    const response = await this.#fetch(`${API_BASE_URL}/${chainId}`);
+    // Type assertion: We have to assume the shape of the response data.
+    const gasPricesResponse =
+      (await response.json()) as unknown as GasPricesResponse;
+    return gasPricesResponse.data;
+  }
+}
+```
+
+Next we'll define the messenger. We give the messenger a namespace, and we expose the method we added above as a messenger action:
+
+```typescript
+// (top of file)
+
+import type { RestrictedMessenger } from '@metamask/base-controller';
+
+const SERVICE_NAME = 'GasPricesService';
+
+export type GasPricesServiceFetchGasPricesAction = {
+  type: `${typeof SERVICE_NAME}:fetchGasPrices`;
+  handler: GasPricesService['fetchGasPrices'];
+};
+
+export type GasPricesServiceActions = GasPricesServiceFetchGasPricesAction;
+
+type AllowedActions = never;
+
+export type GasPricesServiceEvents = never;
+
+type AllowedEvents = never;
+
+export type GasPricesServiceMessenger = RestrictedMessenger<
+  typeof SERVICE_NAME,
+  GasPricesServiceActions | AllowedActions,
+  GasPricesServiceEvents | AllowedEvents,
+  AllowedActions['type'],
+  AllowedEvents['type']
+>;
+
+// ...
+```
+
+Note that we need to add `@metamask/base-controller` as a direct dependency of the package to bring in the `RestrictedMessenger` type (here we assume that our package is called `@metamask/gas-prices-controller`):
+
+```shell
+yarn workspace @metamask/gas-prices-controller add @metamask/base-controller
+```
+
+Finally we will register the method as an action handler on the messenger:
+
+```typescript
+// ...
+
+export class GasPricesService {
+  readonly #messenger: GasPricesServiceMessenger;
+
+  readonly #fetch: typeof fetch;
+
+  constructor({
+    messenger,
+    fetch: fetchFunction,
+  }: {
+    messenger: GasPricesServiceMessenger;
+    fetch: typeof fetch;
+  }) {
+    this.#messenger = messenger;
+    this.#fetch = fetchFunction;
+
+    // Note the action being registered here
+    this.#messenger.registerActionHandler(
+      `${SERVICE_NAME}:fetchGasPrices`,
+      this.fetchGasPrices.bind(this),
+    );
+  }
+
+  // ...
+```
+
+<details><summary><b>View whole file</b></summary><br />
+
+```typescript
+import type { RestrictedMessenger } from '@metamask/base-controller';
+
+const SERVICE_NAME = 'GasPricesService';
+
+export type GasPricesServiceFetchGasPricesAction = {
+  type: `${typeof SERVICE_NAME}:fetchGasPrices`;
+  handler: GasPricesService['fetchGasPrices'];
+};
+
+export type GasPricesServiceActions = GasPricesServiceFetchGasPricesAction;
+
+type AllowedActions = never;
+
+export type GasPricesServiceEvents = never;
+
+type AllowedEvents = never;
+
+export type GasPricesServiceMessenger = RestrictedMessenger<
+  typeof SERVICE_NAME,
+  GasPricesServiceActions | AllowedActions,
+  GasPricesServiceEvents | AllowedEvents,
+  AllowedActions['type'],
+  AllowedEvents['type']
+>;
+
+type GasPricesResponse = {
+  data: {
+    low: number;
+    average: number;
+    high: number;
+  };
+};
+
+const API_BASE_URL = 'https://example.com/gas-prices';
+
+export class GasPricesService {
+  readonly #messenger: GasPricesServiceMessenger;
+
+  readonly #fetch: typeof fetch;
+
+  constructor({
+    messenger,
+    fetch: fetchFunction,
+  }: {
+    messenger: GasPricesServiceMessenger;
+    fetch: typeof fetch;
+  }) {
+    this.#messenger = messenger;
+    this.#fetch = fetchFunction;
+
+    this.#messenger.registerActionHandler(
+      `${SERVICE_NAME}:fetchGasPrices`,
+      this.fetchGasPrices.bind(this),
+    );
+  }
+
+  async fetchGasPrices(chainId: Hex): Promise<GasPricesResponse> {
+    const response = await this.#fetch(`${API_BASE_URL}/${chainId}`);
+    // Type assertion: We have to assume the shape of the response data.
+    const gasPricesResponse =
+      (await response.json()) as unknown as GasPricesResponse;
+    return gasPricesResponse.data;
+  }
+}
+```
+
+</details>
+
+Finally, we go into the `index.ts` for our package and we export the various parts of the data service module that consumers need. Note that we do _not_ export `AllowedActions` and `AllowedEvents`:
+
+```typescript
+export type {
+  GasPricesServiceActions,
+  GasPricesServiceEvents,
+  GasPricesServiceFetchGasPricesAction,
+  GasPricesServiceMessenger,
+} from './gas-prices-service';
+export { GasPricesService } from './gas-prices-service';
+```
+
+### Test file
+
+Great, we've finished the implementation. Now let's write some tests.
+
+We'll create a file `gas-prices-service.test.ts`, and we'll start by adding a test for the `fetchGasPrices` method. Note that we use `nock` to mock the request:
+
+```typescript
+import nock from 'nock';
+
+import type { GasPricesServiceMessenger } from './gas-prices-service';
+import { GasPricesService } from './gas-prices-service';
+
+describe('GasPricesService', () => {
+  describe('fetchGasPrices', () => {
+    it('returns a slightly cleaned up version of what the API returns', async () => {
+      nock('https://example.com/gas-prices')
+        .get('/0x1.json')
+        .reply(200, {
+          data: {
+            low: 5,
+            average: 10,
+            high: 15,
+          },
+        });
+      const messenger = buildMessenger();
+      const gasPricesService = new GasPricesService({ messenger, fetch });
+
+      const gasPricesResponse = await gasPricesService.fetchGasPrices('0x1');
+
+      expect(gasPricesResponse).toStrictEqual({
+        low: 5,
+        average: 10,
+        high: 15,
+      });
+    });
+  });
+});
+```
+
+To make this work, we need to import the `Messenger` class from `@metamask/base-controller`. We also make a little helper to build a messenger:
+
+```typescript
+import { Messenger } from '@metamask/base-controller';
+
+// ...
+
+function buildMessenger(): GasPricesServiceMessenger {
+  return new Messenger().getRestricted({
+    name: 'GasPricesService',
+    allowedActions: [],
+    allowedEvents: [],
+  });
+}
+```
+
+We're not done yet, though. The method isn't the only thing that consumers can use; they can also use the messenger action, so we need to make sure that works too:
+
+```typescript
+// ...
+
+describe('GasPricesService', () => {
+  // ...
+
+  describe('GasPricesService:fetchGasPrices', () => {
+    it('returns a slightly cleaned up version of what the API returns', async () => {
+      nock('https://example.com/gas-prices')
+        .get('/0x1.json')
+        .reply(200, {
+          data: {
+            low: 5,

+
+## How to use a data service
+
+Let's say that we wanted to use our data service that we built above. To do this, we will instantiate the messenger for the data service — which itself relies on a global messenger — and then the data service itself.
+
+First we need to import the data service:
+
+```typescript
+import { GasPricesService } from '@metamask/gas-prices-service';
+```
+
+Then we create a global messenger:
+
+```typescript
+const globalMessenger = new Messenger();
+```
+
+Then we create a messenger for the GasPricesService:
+
+```typescript
+const gasPricesServiceMessenger = globalMessenger.getRestricted({
+  allowedActions: [],
+  allowedEvents: [],
+});
+```
+
+Now we instantiate the data service to register the action handler on the global messenger. We assume we have a global `fetch` function available:
+
+```typescript
+const gasPricesService = new GasPricesService({
+  messenger: gasPricesServiceMessenger,
+  fetch,
+});
+```
+
+Great! Now that we've set up the data service and its messenger action, we can use it somewhere else.
+
+Let's say we wanted to use it in a controller. We'd just need to allow that controller's messenger access to `GasPricesService:fetchGasPrices` by passing it via the `allowedActions` option.
+
+This code would probably be in the controller package itself. For instance, if we had a file `packages/send-controller/send-controller.ts`, we might have:
+
+```typescript
+import { GasPricesServiceFetchGasPricesAction } from '@metamask/gas-prices-service';
+
+type SendControllerActions = ...;
+
+type AllowedActions = GasPricesServiceFetchGasPricesAction;
+
+type SendControllerEvents = ...;
+
+type AllowedEvents = ...;
+
+type SendControllerMessenger = RestrictedMessenger<
+  'SendController',
+  SendControllerActions | AllowedActions,
+  SendControllerEvents | AllowedEvents,
+  AllowedActions['type'],
+  AllowedEvents['type']
+>;
+```
+
+Then, later on in our controller, we could say:
+
+```typescript
+class SendController extends BaseController {
+  // ...
+
+  await someMethodThatUsesGasPrices() {
+    const gasPrices = await this.#messagingSystem.call(
+      'GasPricesService:fetchGasPrices',
+    );
+    // ... use gasPrices somehow ...
+  }
+}
+```
+
+## Learning more
+
+The [`sample-controllers`](../packages/sample-controllers) package has a full example of the data service pattern. including JSDoc for all types, classes, and methods. Check it out and feel free to copy and paste the code you see to your own project.

Subject: [PATCH 0580/1148] Rename team-solana label to team-new-networks
 (#5951)

The `team-solana` issue label in the extension and mobile repos has been
renamed to `team-new-networks`. The `create-update-issues` workflow uses
this to know which teams to assign to tickets representing controller
upgrades. Updating this label in `teams.json` ensures that this workflow
won't break when a new major version of
`@metamask/multichain-transactions-controller` is released.

Subject: [PATCH 0581/1148] Add autofixing of lint warnings for specific
 packages/files (#5187)

Currently, there are a ton of lint warnings, and it would be good to
address them sooner rather than later. To make PRs easier to approve, we
could batch lint violation fixes by codeowner. That is, open PRs
progressively by addressing all lint violations for packages owned by
the Wallet Framework team first, then the Accounts team, then the
Confirmations team, etc.

To do this, we need a way to run ESLint on specific directories. That's
what this PR does. Now you can say, for example:

```
yarn lint:eslint packages/network-controller --fix
```

and now ESLint will run just on `network-controller` files, and autofix
any warnings automatically.

One thing to keep in mind here is that we also want to keep the warning
thresholds file up to date. This is a bit tricky because if we were to
run

```
yarn lint:eslint packages/network-controller --quiet
```

then ESLint would only process lint errors and not warnings + errors. If
this command is successful, i.e., there are no lint errors found, then
we don't want the warning thresholds file to be blown away. So this
commit also contains updates to the logic to ensure this doesn't happen.

Subject: [PATCH 0582/1148] feat: use the new onAssetsMarketData handler
 (#6035)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# feat: use the new onAssetsMarketData handler

## Explanation

### Current State and Problem
The `MultichainAssetsRatesController` currently uses the deprecated
`onAssetsConversion` handler to fetch asset market data from Snaps. This
handler interface is outdated and doesn't align with the current Snaps
SDK architecture, which has evolved to provide better separation of
concerns and more robust data handling.

### Solution
This PR updates the `MultichainAssetsRatesController` to use the new
`onAssetsMarketData` handler in addition of `onAssetsConversion`. This
change:

1. **Improves handler interface**: The new `onAssetsMarketData` handler
provides a more standardized and reliable interface for fetching asset
market data from Snaps
2. **Aligns with current SDK**: Updates the controller to work with the
latest Snaps SDK architecture
3. **Enhances maintainability**: Uses the current best practices for
Snaps integration

### Dependency Updates
Alongside the main functional change, this PR also updates several
Snaps-related dependencies across multiple packages to ensure
compatibility and access to the latest features:

- `@metamask/snaps-sdk`: `^7.1.0` → `^9.0.0`
- `@metamask/snaps-utils`: `^9.4.0` → `^11.0.0`
- `@metamask/snaps-controllers`: `^12.3.1` → `^14.0.1`

These updates are necessary because:
- The new `onAssetsMarketData` handler is available in the updated SDK
versions
- The updated packages provide better performance and security
improvements
- Maintaining consistency across the codebase with the latest Snaps
ecosystem

### Package-Specific Changes
The changes affect multiple packages because they all depend on the
Snaps ecosystem. Each package's changelog has been updated to reflect
the specific dependency changes that apply to it, ensuring transparency
for consumers.

## References

- **Related to**: Snaps SDK migration and handler interface improvements
- **Consumer impact**: This change improves the reliability of asset
market data fetching but maintains backward compatibility for the public
API

## Checklist

packages to resolve any breaking changes

**Note**: All changelogs have been updated for the affected packages:
- `@metamask/assets-controllers`
- `@metamask/account-tree-controller`
- `@metamask/accounts-controller`
- `@metamask/bridge-controller`
- `@metamask/bridge-status-controller`

Subject: [PATCH 0583/1148] fix: poll bridge getTxStatus after confirmation
 (#6052)

## Explanation

Changes getTxStatus polling to trigger after EVM tx is confirmed.
Currently, the polling starts right after transaction submission, which
can take a few seconds to get finalized

Solana status polling still starts right after submission

+- Wait until a bridge transaction is confirmed before polling for its status. This reduces (or fully removes) premature `getTxStatus` calls, and enables adding batched bridge txs to history before its transaction Id is available ([#6052](https://github.com/MetaMask/core/pull/6052))

Subject: [PATCH 0584/1148] fix: Auth Pubkey persistance in the Seedless
 controller state (#6055)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
In the SeedlessOnboardingController, we stored the `AuthPubKey` in the
controller state, to be used in the password-change sync flow (i.e.
password change can be detected by comparing the latest AuthPubKey from
the server against the local AuthPubKey stored in the controller state).
Currently we have a method to persist the AuthPubKey,
`#persistAuthPubKey`, which updates the AuthPubKey state whenever (new)
vault is created or updated with new AuthData from the server.
The issue that `#persistAuthPubKey` isn't being called on every vault
update, even though the data should be updated whenever `Vault` is
updated.

This PR addresses the incorrect implementation for persisting
`AuthPubKey` in the controller state as well as updated the tests with
correct mocks and order of mocks.

**Previously, we weren't able to detect this issue due to the incorrect
mocks in the test cases.**

Subject: [PATCH 0586/1148] feat: keep correct order of secret data backups
 (SRP and Private Key) (#6047)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This pr mainly addresses the following issues regarding to the import
order of Different SecretData backup ~
The current implementation of `fetchAllSecretData` method returns the
both Srp (Mnemonics) and Private key backup in object mapping data
structure, i.e.
```ts
{
  Mnemonics: [<Mnemonic_1>, <Mnemonic_2>, <Mnemonic_3>],
  PrivateKey: [<PrivateKey_1>, <PrivateKey_2>],
}
```
This data structure preserves the order of each SecretType, `Mnemonics`
and `PrivateKey` (in an array) but that doesn't solves the order of
backup created for all SecretTypes. For instance,
user created backups in order of `Mnemonic_1`->`Mnemonic_2` ->
`PrivateKey_1` -> `PrivateKey_2` -> `Mnemonic_2`.
With the above data structure, it's difficult to find which backup comes
first when the client imports the SecretData in the frontend.

So, in this PR, the return values of `fetchAllSecretData` are updated to
the Array of SecretMetadata objects, for e.g.
```ts
[
  { data: <Mnemonic_1>, type: Mnemonic, timestamp: <Timestamp-1> },
  { data: <Mnemonic_2>, type: Mnemonic, timestamp: <Timestamp-2> },
  { data: <PrivateKey_2>, type: PrivateKey, timestamp: <Timestamp-3> },
  { data: <Mnemonic_3>, type: Mnemonic, timestamp: <Timestamp-4> },
  ...
]
```
This data structure will help the clients to know in which order the
secret data were imported as well as includes the type, so that the
client can process the relevant imports.

Beside this main change, additional validations were added in the
`fetchAllSecretData` method, which are ~
- Throws error when the client receives the empty array of `SecretData`
(which is impossible in working scenario).
- Throws error when the first `SecretData` is not `Mnemonics` type (the
first secretData backup must always be the Mnemonics).
Moreover, the PR includes some internal refactoring (mostly on the
`fetchAllSecretData` method), because with the new validations added and
some logic changes, the method becomes a bit harder to read.

Subject: [PATCH 0590/1148] feat: submit swap STX with addTransactionBatch
 (#6058)

## Explanation

Replaces the STX tx submission logic with a call to
`TransactionController:addTransactionBatch`. Batched transactions are
keyed by `batchId` in txHistory, and have incomplete metadata until they
either fail or are confirmed

After confirmation/failure, the txHistoryItem is re-keyed with txId and
missing fields are populated

`updateTransaction` is called after tx signing to set the tx type of
batched txs

+- Bump `@metamask/utils` from `^11.2.0` to `^11.4.2` ([#6054](https://github.com/MetaMask/core/pull/6054))
+- Improve performance of `isValidHexAddress` and `toChecksumHexAddress` ([#6054](https://github.com/MetaMask/core/pull/6054))
+  - Replace `ethereumjs-util` lib with faster `@metamask/utils` functions
+  - Memoize `isValidHexAddress` and `toChecksumHexAddress` functions
 - Update `createServicePolicy` to reduce circuit break duration from 30 minutes to 2 minutes ([#6015](https://github.com/MetaMask/core/pull/6015))
   - When hitting an API, this reduces the default duration for which requests to the API are paused when perceived to be unavailable

Subject: [PATCH 0594/1148] feat: add
 `AuthenticationController:getUserProfileMetaMetrics` new method/action
 (#6068)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR adds a new `getUserProfileMetaMetrics` method to
`AuthenticationController`.
This methods queries the Authentication API and retrieves the currently
authenticated user's metametrics data, in the form of
`UserProfileMetaMetrics` type.

```ts
export type UserProfileMetaMetrics = {
  profile_id: string;
  created_at: string;
  lineage: {
    metametrics_id: string;
    agent: Platform; // 'mobile' | 'extension' | 'portfolio' | 'infura'
    created_at: string;
    updated_at: string;
    counter: number;
  }[];
};
```

Extension test-drive PR:
- https://github.com/MetaMask/metamask-extension/pull/34060

The PR above is only a demo, and **shouldn't** be merged.
It adds a call to `getUserProfileMetaMetrics` just after dispatching
account syncing.

In order to view the results, switch to the test-drive PR branch,
`yarn`, `yarn start`.
Then complete onboarding, open the dev tools, network tab, and filter by
"authentication".
You should see a `metametrics` call every time you refresh the extension
page (more convenient to do in full screen mode).

-->

Patch release for the following packages:
	•	@metamask/address-book-controller
	•	@metamask/assets-controllers
	•	@metamask/controller-utils
	•	@metamask/ens-controller
	•	@metamask/message-manager
	•	@metamask/notification-services-controller
	•	@metamask/preferences-controller
	•	@metamask/signature-controller
	•	@metamask/transaction-controller

This patch release incorporates the improvements from [MetaMask core PR
#6054](https://github.com/MetaMask/core/pull/6054), which memoizes the
`isValidHexAddress` and `toChecksumHexAddress` functions in
`@metamask/controller-utils`.

It also includes the updates from [@metamask/utils
changelog](https://github.com/MetaMask/utils/blob/main/CHANGELOG.md#fixed),
which added memoization for `isValidChecksumAddress` and
`isValidHexAddress`.

From 05abbbaa3d088027efcf6a89fd0417a4c101af01 Mon Sep 17 00:00:00 2001
From: Dario Anongba Varela <dario.anongba@gmail.com>

Subject: [PATCH 0597/1148] fix: use scopes to retrieve chain ID (#6072)

## Explanation

We currently use the address to identify what network the account
belongs to, yet that method is incorrect as:
- accounts span multiple networks
- addresses can be the same on different networks.

The current implementation leads to a bug where the network will always
be Mainnet for Solana and Bitcoin, preventing testnets to work. It would
also fail to work on EVM networks if this function was used.

The solution, using scopes, fixes the problem for Bitcoin and introduces
no regression for Solana.

Subject: [PATCH 0598/1148] Add fallback to sequential hook when
 `publishBatchHook` returns empty (#6063)

## Explanation
This PR aims to add a fallback mechanism to use the sequential hook when
`publishBatchHook` returns empty. This will help us to handle case when
`publishBatchHook` is defined by the client as it's for smart
transaction but smart transaction is disabled.

 isSnapConfirmationEnabled (#6077)

## Explanation

**BREAKING** Submit Solana transactions using `onClientRequest` RPC call
by default, which hides the Snap confirmation page from clients. Clients
will need to remove conditional redirect the the confirmation page on tx
submission

Subject: [PATCH 0600/1148] chore: add isSingleSwapBridgeButtonEnabled feature
 flag (#6078)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so

* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Adding an optional `isSingleSwapBridgeButtonEnabled` feature flag that
indicates whether Swap and Bridge entrypoints should be combined. Used
by the extension client

Subject: [PATCH 0601/1148] feat: remove storage schema enforcement (#6075)

## Explanation

Currently, public `UserStorageController` methods that interact with the
storage SDK implicitly enforce schema validation
(`validateAgainstSchema: true`). This is not suitable for all scenarios,
as some consumers may need to store data that does not conform to a
predefined schema or manage schema validation externally.

As a DX improvement, This PR removes the schema enforcement for user
storage paths, so that developers are relieved from having to update the
schema before using the SDK or Controllers for their features.

Subject: [PATCH 0608/1148] feat(identity): trace performance of backupAndSync
 operations (#6050)

## Explanation

### Current State
The UserStorage controller's syncing features (contact syncing and
account syncing) lacked performance tracing, making it difficult to
monitor sync performance, identify bottlenecks, and debug issues in the
backup & sync functionality. This was particularly problematic given the
critical nature of these features for user data synchronization across
devices.

### Solution
This PR adds comprehensive performance tracing to UserStorage syncing
operations, following the established pattern used by other core
controllers (BridgeController, SignatureController,
TransactionController). The implementation includes:

**Dependency Injection**: Added `TraceCallback` parameter to
`UserStorageController` constructor with graceful fallback when no trace
function is provided.

**Type Updates**: Extended `ContactSyncingOptions` and
`AccountSyncingOptions` interfaces to include optional `trace`
parameter.

**Key Operations Traced**:
- `Contact Sync Full` - Complete contact synchronization between local
and remote storage
- `Contact Sync Update Remote` - Individual contact updates pushed to
remote storage
- `Contact Sync Delete Remote` - Individual contact deletions marked in
remote storage
- `Account Sync Full` - Complete account synchronization with entropy
source handling
- `Account Sync Save Individual` - Individual account saves to user
storage

**Clean Implementation**: Used inline ternary pattern (`trace ? await
trace(config, fn) : await fn()`) instead of verbose function naming,
making the code more readable and maintainable.

### Benefits
This tracing implementation will provide:
- **Performance Visibility**: Monitor sync operation duration and
identify slow operations
- **Bottleneck Detection**: Pinpoint which parts of sync are causing
delays
- **Error Tracking**: Better observability into failed sync operations
- **Data Insights**: Track sync volume (number of contacts/accounts
processed)
- **Debugging Support**: Nested trace contexts for complex sync
scenarios

The implementation maintains backward compatibility and follows existing
controller patterns, making it ready for integration in both extension
and mobile clients.

Subject: [PATCH 0613/1148] feat: export UrlScanCacheEntry (#6095)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

In the extension, we are wanting to access the cache entries. In order
to not repeat ourselves and make maintenance easier, we should export
this type instead of duplicating the type inside of the extension.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

This release introduces a major version update for the Phishing
Controller as it introduces a breaking change to the `scanUrl` function.
It also introduces an export for the `UrlScanCacheEntry` type as well so
that it can be used by the extension and mobile.

Subject: [PATCH 0617/1148] Use new team labels in teams.json (#6107)

This fixes the workflow responsible for creating tickets in Extension
and Mobile when new major versions of packages are published so that
they get created successfully with the correct labels (some of which
changed recently).

Subject: [PATCH 0619/1148] fix: TAT-1263 pooled-staking data fails to refresh
 when on unsupported chainId (#6106)

## Explanation

<!--

Currently, when the GNS active chainId isn't supported by pooled-staking
we cannot fetch pooled-staking data. Supported chains are Ethereum
mainnet and Hoodi Testnet.

To fix this, we fallback to Ethereum mainnet when the active chain isn't
supported.

Subject: [PATCH 0621/1148] feat: persist access token and metadata access
 token in seedless controller (#6060)

## Explanation

- This update introduces two new tokens, accessToken and
metadataAccessToken, to the SeedlessOnboardingController.

- These tokens are essential for pairing with the profile sync auth
service and accessing the metadata service before the vault is created
or unlocked.

- The changes include updates to the controller state, methods for
handling these tokens, and corresponding tests to ensure proper
functionality and error handling when tokens are missing.

- Additionally, the vault data structure has been modified to include
the new accessToken. Tests have been added to verify the correct
behavior of the controller with respect to these tokens.

- Removed unused nodeAuthTokens from vault.

- Toprf sdk updated to use metadataAccessToken

+- Added `access_token` and `metadata_access_token` in seedless controller state. ([#6060](https://github.com/MetaMask/core/pull/6060))
+  - `access_token` can be used by profile sync pairing and for other apis access after wallet is unlocked.
+  - `metadata_access_token` is used to give access for web3auth metadata apis.

Subject: [PATCH 0623/1148] feat!: use `@metamask/account-api` in the
 `AccountTreeController` (#6115)

## Explanation

Use the new `@metamask/account-api` that introduces the concept of
account wallet and account group into a generic account API/SDK package.

This controller was already using those concepts, but it now properly
implements well-defined types that will also be used by multichain
accounts.

 ### Changed
 
+- **BREAKING:** Add `@metamask/account-api` peer dependency ([#6115](https://github.com/MetaMask/core/pull/6115))
+- **BREAKING:** Types `AccountWallet` and `AccountGroup` have been respectively renamed to `AccountWalletObject` and `AccountGroupObject` ([#6115](https://github.com/MetaMask/core/pull/6115))
+  - Those names are now used by the `@metamask/account-api` package to define higher-level interfaces.
 - **BREAKING:** Bump peer dependency `@metamask/snaps-controllers` from `^12.0.0` to `^14.0.0` ([#6035](https://github.com/MetaMask/core/pull/6035))
 - Bump `@metamask/snaps-sdk` from `^7.1.0` to `^9.0.0` ([#6035](https://github.com/MetaMask/core/pull/6035))
 - Bump `@metamask/snaps-utils` from `^9.4.0` to `^11.0.0` ([#6035](https://github.com/MetaMask/core/pull/6035))
 - Properly export `AccountWalletCategory` constant and conversion functions ([#6062](https://github.com/MetaMask/core/pull/6062))
 
+### Removed
+
+- **BREAKING:** No longer export `AccountWalletCategory`, `toAccountWalletId`, `toAccountGroupId` and `toDefaultAccountGroupId` ([#6115](https://github.com/MetaMask/core/pull/6115))
+  - You should now import them from the `@metamask/account-api` package (peer dependency).

Subject: [PATCH 0624/1148] fix: phishing controller bulk scan action type
 export (#6105)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR introduces updates to the `PhishingController` and
`NftController` to improve type definitions and action registration. We
now create the `PhishingControllerBulkScanUrlsAction` type in the
`PhishingController` to be exported and then used within the
`NftController`.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?

Subject: [PATCH 0627/1148] Release 466.0.0 (#6120)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

This PR releases the phishing and assets controller as I have moved a
public type from the assets controller to the phishing controller. The
phishing controller is being released as a minor version with the Assets
controller as a major version.



* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR releases the phishing and assets controller as I have moved a
public type from the assets controller to the phishing controller. The
phishing controller is being released as a minor version with the Assets
controller as a major version.

Subject: [PATCH 0631/1148] feat: auto register Messenger actions (#5927)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

### Add `registerMethodActionHandlers` method for simplified bulk action
handler registration

#### 🎯 **Summary**
This PR introduces a new `registerMethodActionHandlers` method to
`BaseController`, `Messenger`, and `RestrictedMessenger` classes that
simplifies the process of registering multiple action handlers at once,
reducing boilerplate code and improving developer experience.

#### 🚀 **Problem**
Currently, controllers need to manually register each action handler
individually, leading to repetitive boilerplate code:

```typescript
// Current approach - lots of repetition
this.messagingSystem.registerActionHandler('MyController:method1', this.method1.bind(this));
this.messagingSystem.registerActionHandler('MyController:method2', this.method2.bind(this));
this.messagingSystem.registerActionHandler('MyController:method3', this.method3.bind(this));
this.messagingSystem.registerActionHandler('MyController:method4', this.method4.bind(this));
```

This approach is:
- **Verbose**: Requires multiple lines for each handler
- **Error-prone**: Easy to forget `.bind(this)` or make typos
- **Difficult to maintain**: Changes require updating multiple lines
- **Inconsistent**: Different controllers may use different patterns

#### 💡 **Solution**
The new `registerActionHandlers` method allows bulk registration with
smart defaults:

```typescript
// New approach - clean and concise
this.registerActionHandlers(['method1', 'method2', 'method3', 'method4']);
```

#### ✨ **Key Features**

##### 1. **Bulk Registration**
Register multiple action handlers with a single method call:
```typescript
this.registerActionHandlers(['getAccounts', 'setSelectedAccount', 'updateAccount']);
```

##### 2. **Automatic Method Binding**
Methods are automatically bound to the controller instance - no more
forgotten `.bind(this)`:
```typescript
// The method is automatically bound to the controller instance
this.registerActionHandlers(['getPrivateData']);
```

#### 📝 **Usage Examples**

##### Basic Usage
```typescript
class MyController extends BaseController {
  constructor(messenger) {
    super(/* ... */);

    // Register multiple handlers at once
    this.registerActionHandlers([
      'getState',
      'updateSettings',
      'clearData',
    ]);
  }
}
```

##### Advanced Usage with Custom Exclusions and Exceptions
```typescript
class AdvancedController extends BaseController {
  constructor(messenger) {
    super(/* ... */);

    this.registerActionHandlers(['method1', 'method2', 'method3', 'internalMethod']);
  }
}
```

### 🔄 **Migration Guide**
This feature is optional and backward compatible. Controllers can
gradually migrate to using `registerActionHandlers` for improved
maintainability:

```typescript
// Before
this.messagingSystem.registerActionHandler('Controller:method1', this.method1.bind(this));
this.messagingSystem.registerActionHandler('Controller:method2', this.method2.bind(this));

// After
this.registerActionHandlers(['method1', 'method2']);
```

### 🤖 **Automated Action Type Generation**

To complement the bulk registration feature, this PR also introduces an
automated script that generates TypeScript action types from controller
methods, eliminating the need to manually create and maintain action
type definitions.

#### **New Script: `generate-method-action-types.ts`**

```bash
# Auto-generate action types for all controllers
yarn ts-node scripts/generate-method-action-types.ts
```

**What it does:**
- **Discovers controllers**: Automatically finds all controllers with
`MESSENGER_EXPOSED_METHODS` constants
- **Extracts metadata**: Parses JSDoc comments and method signatures
using TypeScript AST
- **Generates types**: Creates properly formatted action type
definitions

**Generated Output Example:**
```typescript
/**
 * Returns the Infura network client with the given ID.
 *
 * @param networkClientId - A network client ID.
 * @returns The network client.
 * @throws If a network client does not exist with the given ID.
 */
export type NetworkControllerGetNetworkClientByIdAction = {
  type: `NetworkController:getNetworkClientById`;
  handler: NetworkController['getNetworkClientById'];
};
```

#### **Development Workflow**
1. Add/modify methods in a controller
2. Update the `MESSENGER_EXPOSED_METHODS` constant
3. Run `yarn ts-node scripts/generate-method-action-types.ts` or `yarn
run generate-method-action-types`
4. Commit the generated/updated action type files

**Output Files:**
```typescript
packages/network-controller/src/network-controller-method-action-types.ts
packages/address-book-controller/src/addressbook-controller-method-action-types.ts
```

Subject: [PATCH 0633/1148] fix: Removed access token validation on wallet
 locked (#6133)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR removes the `access_token` validation from the
`checkIsPasswordOutdated` and `#executeWithTokenRefresh` when the wallet
locked and the following issue.
The `checkIsPasswordOutdated` method can be called even when the wallet
(vault) is locked but during the locked period, `access_token` is not
accessible. This triggers the `refreshAuthToken` method whenever wallet
is unlocked.

Subject: [PATCH 0638/1148] fix: Fix `yarn create-package` (#6126)

## Explanation

The `create-package` script was failing due to unused `ts-expect-error`
directives. The directives became unused recently in #5810 after an
update.

To test this, run `yarn create-package --help`. It should no longer
throw an error.

## References

Broken since #5810

Subject: [PATCH 0639/1148] docs: Add missing step in "new package" docs
 (#6131)

## Explanation

Add a missing step in the contributor documentation for creating a new
package. The template covers most things, but the team ownership is at
the root level and required by our Yarn constraints.

Subject: [PATCH 0640/1148] chore: Rename `BaseControllerV2` module to
 `BaseController` (#6128)

## Explanation

The internal `BaseControllerV2` module has been renamed to
`BaseController`. No external-facing changes. The `V2` in the module
name was an artifact from when we had two controller versions.

Subject: [PATCH 0641/1148] feat: Create new `@metamask/messenger` package
 (#6127)

## Explanation

The `Messenger` class and related code has been copied from the
`@metamask/base-controller` package to a new `@metamask/messenger`
package. Separating the messenger from the base controller reduces the
impact of base controller breaking changes, and aligns well with our
plans to use the `Messenger` class more often for non-controllers.

This move will also simplify the effort to implement some new breaking
changes to the `Messenger` class (the new `delegation` method, see issue
#5626). This new package will not be released until the breaking changes
have been applied here. Those changes will come in later PRs; for now,
the code was copied over with zero changes.

Subject: [PATCH 0645/1148] Fix/revoke token validation (#6136)

## Explanation
- This PR changes the usage of revokeToken from mandatory to optional in
vault.
- The reason why its done because revokeToken is not accessible in a
device if max key chain length exceeds. Although this condition should
never happen for a general user. Making it optional will prevent user
from getting stuck in dead end login situation.

Subject: [PATCH 0649/1148] fix: handle snaps error (#6104)

## Explanation

The `MultichainAssetsRatesController` was experiencing crashes when Snap
requests failed due to parameter validation errors.

the error handling was insufficient - when Snap requests failed, the
controller will send a sentry error rather than gracefully handling the
error and continuing operation.

+- Improve error handling in `MultichainAssetsRatesController` for Snap request failures ([#6104](https://github.com/MetaMask/core/pull/6104))
+  - Enhanced `#handleSnapRequest` method with detailed error logging and graceful failure recovery
+  - Added null safety checks to prevent crashes when Snap requests return null
+  - Controller now continues operation when individual Snap requests fail instead of crashing
+  - Added comprehensive unit tests covering various error scenarios including JSON-RPC errors and network failures

Subject: [PATCH 0651/1148] Improve create-update-issues workflow (#6090)

We have a workflow to automatically create tickets in both Extension and
Mobile whenever a new major version of a package is published. However,
there are some issues with this workflow:

- Some of the team labels referenced in `teams.json` will be or have
already changed in the Extension and Mobile repos.
- If if a team label does _not_ exist in either Extension or Mobile, the
command to create the issue can fail. This seems to prevent other issues
from being created.
- If the workflow fails midway through and is run again, then it can
create duplicate issues.
- It's actually difficult to tell which issues get successfully created
and which don't, because there isn't much output from this workflow.
- The description in the issue is very terse. It says "Please update
this package", assigns it to a team, and doesn't explain why they should
care or what they should do next.
- The script in the workflow is difficult to maintain because it's
inline.
- It's difficult to test the script without forking the repo.

This commit extracts the script to a separate file and addresses the
above issues by adding better failure handling and logging, expanding
the issue description, adding a dry-run mode, and ensuring that
duplicate issues do not get created.

Subject: [PATCH 0654/1148] fix: implicit tokens add (#6012)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation
This PR includes improvements to both the TokenDetectionController and
the CurrencyRateController:

✅ Fix for token detection triggering when toggle is off:
Token detection should not run when the detection toggle is disabled.
However, it was still triggered on user refresh even when the toggle was
off. This PR fixes that issue.

✅ Improved handling of detected tokens:
Previously, detected tokens were added to `allDetectedTokens` and then
imported manually through the UI, which was messy and led to performance
issues. Now, detected tokens are implicitly added directly to allTokens,
simplifying the flow and improving performance.

✅ Behavior adjusted based on basic functionality status:

- When basic functionality is disabled, token detection now uses direct
RPC calls.
- When basic functionality is disabled, requests to CryptoCompare are
also disabled to avoid unnecessary calls.

## Changelog

### `@metamask/assets-controllers`

UPDATE: Improve `TokenDetectionController` and `CurrencyRateController`
behavior to respect feature toggles and reduce unnecessary operations.
- Prevent `TokenDetectionController` from running when the detection
toggle is off, including during user refresh.
- Automatically add detected tokens to `allTokens` instead of routing
them through `allDetectedTokens` and UI import, streamlining the flow
and improving performance.
- Fall back to direct RPC-based token detection when basic functionality
is disabled.
- Skip CryptoCompare requests entirely when basic functionality is
turned off to reduce external dependencies.

 ### Changed
 
+- Improved `TokenDetectionController` token handling flow ([#6012](https://github.com/MetaMask/core/pull/6012))
+  - Detected tokens are now implicitly added directly to `allTokens` instead of being added to `allDetectedTokens` first
+  - This simplifies the token import flow and improves performance by eliminating the manual UI import step
+  - Enhanced `TokenDetectionController` to use direct RPC calls when basic functionality is disabled ([#6012](https://github.com/MetaMask/core/pull/6012))
+  - Token detection now falls back to direct RPC calls instead of API-based detection when basic functionality is turned off
 - Bump `@metamask/keyring-api` from `^18.0.0` to `^19.0.0` ([#6146](https://github.com/MetaMask/core/pull/6146))
 
 ### Fixed
 
+- Fix `TokenDetectionController` to respect the detection toggle setting ([#6012](https://github.com/MetaMask/core/pull/6012))
+  - Token detection will no longer run when the detection toggle is disabled, even during user refresh operations
+- Improved `CurrencyRateController` behavior when basic functionality is disabled ([#6012](https://github.com/MetaMask/core/pull/6012))
+  - Disabled requests to CryptoCompare when basic functionality is turned off to avoid unnecessary API calls
 - Improve error handling in `MultichainAssetsRatesController` for Snap request failures ([#6104](https://github.com/MetaMask/core/pull/6104))
   - Enhanced `#handleSnapRequest` method with detailed error logging and graceful failure recovery
   - Added null safety checks to prevent crashes when Snap requests return null

Subject: [PATCH 0655/1148] feat: Stop persisting `permissionActivityLog` state
 (#6156)

## Explanation

The `permissionActivityLog` property of the `PermissionLogController`
state tracks all calls to restricted methods. This was intended as a
diagnostic aid, but in practice it is rarely used. This log is causing
performance issues related to disk writes because it can be triggered
while the wallet is idle (by snaps calling restricted methods).

To reduce the performance burden of this property, it is no longer
persisted. This list will still be available in-memory for diagnosing
problems, but will not be preserved across restarts.

Subject: [PATCH 0656/1148] fix: Update access token validation and retrieval
 from vault and state  (#6155)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR includes fix and update to get the `accessToken` value from the
controller.
`accessToken` data is saved in both vault and state (as non-persisted
value) from the `OAuth Authentication` and previously, we only read and
validate it from the state when updating the SeedlessOnboarding vault
data.

However, there's an edge case in the client (especially in the
extension) where `acessToken` is persisted to vault but removed from the
state. Please refer to this extension bug
(https://github.com/MetaMask/metamask-extension/issues/34437) as an
example.
In that case, `accessToken` value is persisted to vault and set
(temporarily in mem) to state after the rehydration (unlock), however
when the user refresh the page before the onboarding is finished, the
`accessToken` value is removed from the state(memory) and when user
tries to rehydrate, the controller throw the `InvalidAccessToken` error
as it's not available in the in-memory state anymore.

This PR fixes the issue by checking the access-token in both in-memory
state and in the encrypted vault.

Subject: [PATCH 0660/1148] fix: don't poll indefinitely for bridge status if
 500 errors (#6149)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR fixes an issue where we would poll indefinitely if the Bridge
API keeps returning a 500 error. The original bug was that the tx was
submitted on the wrong chain and therefore the txHash would never appear
on the chain we are querying for, so we would poll the Bridge API
indefinitely.

 - Improved `TokenDetectionController` token handling flow ([#6012](https://github.com/MetaMask/core/pull/6012))
   - Detected tokens are now implicitly added directly to `allTokens` instead of being added to `allDetectedTokens` first

Subject: [PATCH 0670/1148] feat: configuration passwordOutdatedCache in the
 controller (#6169)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This PR adds optional `passwordOutdatedCache` (in ms) to the
`SeedlessOnboardingController` constructor params.
If user provides `passwordOutdatedCache`, we will use this value when
setting cache for the `passwordOutdatedCheck`, otherwise the default
value (10 seconds) will be used.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890

Subject: [PATCH 0673/1148] fix(accounts-controller): allow extra-properties in
 options BIP-44 Snap accounts (#6189)

## Explanation

This is required since Snaps that supports BIP-44 accounts might have
more options than the one we use to detect "legacy BIP-44 options".

`superstruct.object` is strict and does not allow extra-properties,
while `superstruct.type` acts as normal structural typing (like in
TypeScript).

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
### What is the current state of things and why does it need to change?

The AccountTreeController organizes accounts into groups but has no
concept of which group is currently selected. Meanwhile,
AccountsController tracks the selected individual account. This creates
a disconnect between account selection at the individual level and group
level.

### What is the solution your changes offer and how does it work?

Added `selectedAccountGroup` state to AccountTreeController with
bidirectional synchronization:

- **Initialization**: Sets selectedAccountGroup based on
AccountsController's currently selected account
- **AccountsController → AccountTreeController**: Listens to
`selectedAccountChange` events and updates selectedAccountGroup to match
the selected account's group
- **AccountTreeController → AccountsController**: When
`setSelectedAccountGroup` is called, selects the first account in that
group via AccountsController

The sync is idempotent to prevent infinite loops - changes only occur
when the target state differs from current state.

### Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
- `#getFirstAccountInGroup` method - when selecting a group, we need to
pick a specific account to tell AccountsController about, so we choose
the first one

Subject: [PATCH 0676/1148] feat: adds revokeRefreshToken public function.
 (#6187)

## Explanation

- This PR moves revoke token call in a separate public function.
Revoking refresh token is not a must after submit password so can be
done post unlock and even when it fails it shouldn't affect user wallet
unlock.

Subject: [PATCH 0678/1148] feat(account-tree-controller): multichain account
 support + use 1 group per account (#6185)

## Explanation

- Add BIP-44/multichain accounts support, those are being attached to
the `entropy` wallet category.
- Now use one account group per account for `snap` and `keyring` wallet
categories, we used to group all accounts under the `'default'` group,
but we now compute the group ID using the address of each accounts.
- Compute account group name based on their underlying account, this
replaces the previous `'Default'` name for groups.

Subject: [PATCH 0680/1148] perf!: Use single call to update native balances
 when enabled (#6099)

## Explanation

This PR modifies `AccountTrackerController.refresh` to use the contract
from `SINGLE_CALL_BALANCES_ADDRESS_BY_CHAINID` used in other asset
controllers when available. This reduces the amount of fetch calls made
to update native balances **drastically**. If the contract is not
available, we fall back to the previous behaviour.

Additionally this PR refactors `getStakedBalanceForChain` to take
multiple addresses and use multicall to fetch staked balances. This also
drastically reduces the number of fetch calls used, but is a **breaking
change** since the parameters and return value has changed for
`getStakedBalanceForChain`.

Subject: [PATCH 0681/1148] fix: update block number (#6197)

## Explanation

- **Current State & Problem:** Explained how the TokenBalancesController
was returning stale cached balances instead of current blockchain data
- **Solution:** Described the forced block number update mechanism that
bypasses stale cache
- **How It Works:** Detailed the technical implementation with bullet
points
- T**echnical Context:** Added explanation for reviewers unfamiliar with
blockchain caching

Subject: [PATCH 0689/1148] feat(account-tree-controller): auto-select EVM
 account (if available) with `setSelectedAccountGroup` (#6208)

## Explanation

The controller will now try to default to an EVM account from a groups
when it's possible.

Thus, making sure the `AccountsController.getSelectedAccount` to always
refer to the proper EVM account once we start using account groups as
the new account model.

Subject: [PATCH 0690/1148] refactor(account-tree-controller): add type field
 for each tree node + improve typing overall (#6214)

## Explanation

Add new `type` field for each wallets/groups.

This is used as a "tag", so proper node types can be inferred by the
compiler.

e.g:
```ts
// Using wallet as root node:
if (wallet.type === AccountWalletType.Entropy) {
  console.log(wallet.metadata.entropy.id);

  // This `wallet` is narrowed down to `AccountWalletEntropyObject`, it knows that
  // `wallet.groups` are `AccountGroupMultichainAccountObject`, so we can use
  // the `groupIndex` safely here too.
  for (const group of Object.values(wallet.groups)) {
    console.log(group.metadata.entropy.groupIndex);
  }
}

if (wallet.type === AccountWalletType.Snap) {
  console.log(wallet.metadata.snap.id);
}

if (wallet.type === AccountWalletType.Keyring) {
  console.log(wallet.metadata.keyring.type);
}

// Using group as root node:
if (group.type === AccountGroupType.SingleAccount) {
  // No real metadata for this, however, we enforced the `accounts` to be
  // a `[AccountId]` tuple, so it is safe to do:
  console.log(group.accounts[0]);

  // And this should not build:
  console.log(group.accounts[1]); // ERROR: Tuple type '[string]' of length '1' has no element at index '1'.
}

if (group.type === AccountGroupType.MultichainAccount) {
  console.log(group.metadata.groupIndex);

  // For multichain accounts group we have "at least 1" account, but we could have more.
  console.log(group.accounts[0]);
  console.log(group.accounts[1]); // Assuming we have 2 accounts here.
}
```

 ## [Unreleased]
 
+### Added
+
+- Add `group.type` tag ([#6214](https://github.com/MetaMask/core/pull/6214))
+  - This `type` can be used as a tag to strongly-type (tagged-union) the `AccountGroupObject`.
+- Add `group.metadata` metadata object ([#6214](https://github.com/MetaMask/core/pull/6214))
+  - Given the `group.type` you will now have access to specific metadata information (e.g. `groupIndex` for multichain account groups)
+
 ### Changed
 
+- **BREAKING:** Bump peer dependency `@metamask/account-api` from `^0.3.0` to `^0.5.0` ([#6214](https://github.com/MetaMask/core/pull/6214))
+- **BREAKING:** Move `wallet.metadata.type` tag to `wallet` node ([#6214](https://github.com/MetaMask/core/pull/6214))
+  - This `type` can be used as a tag to strongly-type (tagged-union) the `AccountWalletObject`.
 - Defaults to the EVM account from a group when using `setSelectedAccountGroup` ([#6208](https://github.com/MetaMask/core/pull/6208))
   - In case no EVM accounts are found in a group (which should not be possible), it will defaults to the first account of that group.

Subject: [PATCH 0693/1148] refactor(multichain-account-service)!: move
 `MultichainAccount{Wallet,Group}` implementations (#6216)

## Explanation

Moving the implementations out of `@metamask/account-api` to have them
closer to the service (which makes more sense too).

Beware, `MultichainAccount` has been renamed to `MultichainAccountGroup`
to emphasis more on the the "group" aspect of multichain accounts.

Subject: [PATCH 0698/1148] feat(multichain-account-service)!: add
 `KeyringAccount` instead of `InternalAccount` (#6227)

## Explanation

We now use `KeyringAccount` instead of `InternalAccount` since we don't
really have any use of the `account.metadata` anymore since the
introduction of groups/wallets `metadata`:
- https://github.com/MetaMask/core/pull/6214

We still rely on the `AccountsController` to get the
`KeyringAccount`-compatible accounts for EVM accounts.

Once we have the unified keyring API, we could just use keyrings to get
their accounts, though, for the moment we rely on `getAccount` and
`getAccounts` to be sync methods, and we would have to change this to
fit the current multichain account architecture.

Subject: [PATCH 0699/1148] feat: Introduce new Launch Darkly environment types
 (#6228)

## Explanation

Platform team is working on unifying build commands. To introduce new
commands we need to introduce additional LaunchDarkly EnvironmentType
variables for them. Here is the target state:

Subject: [PATCH 0701/1148] Seedless controller: Add "@noble" dependencies as
 main dependencies (#6101)

## Explanation

The dependencies `@noble/hashes`, `@noble/ciphers`, `@noble/curves` were
mistakenly listed as dev-dependencies in `seedless-controller`. Moving
them to main dependencies here.

Also upgrading all `@noble` dependencies to most recent version. In
particular, `@noble/ciphers` has now a v1 [which is
audited.](https://github.com/paulmillr/noble-ciphers/releases/tag/1.0.0)

   - This controller manages the retrieval and caching of remote feature flags. It fetches feature flags from a remote API, caches them, and provides methods to access and manage these flags. The controller ensures that feature flags are refreshed based on a specified interval and handles cases where the controller is disabled or the network is unavailable.

Subject: [PATCH 0703/1148] fix: Preserve `origin` and `type` when adding batch
 with hook (#6178)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR aims to preserve `origin` and `type` property when adding a
batch with hook.

As part of this PR; also adding an optional parameter `fiatValue` which
then will be later to matched with metrics for transactions like swaps
and bridge.

Note: `origin` is already preserved while adding batch 7702.

From 086965987d830321a61384fdbf50e34a81874b12 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0706/1148] feat: add multichain account syncing checks & logic
 branches (#6215)

## Explanation

This PR paves the way for Multichain Account Syncing by adding a new
callback to `UserStorageController` that will be wired to the
`enableMultichainAccounts` remote feature flag on clients.
When `enableMultichainAccounts` is `true`, then the current (and soon to
be legacy) Account Syncing method will stop sending updates to the user
storage, and only act as a legacy restoration vessel.

The reason behind all those changes is that `AccountTreeController` will
be responsible for Multichain Account Syncing.

This PR also removes an unused public method.

Changelog below:

```md
### Added

- `UserStorageController` optional config callback `getIsMultichainAccountSyncingEnabled`, and `getIsMultichainAccountSyncingEnabled` public method / messenger action
  - This callback needs to be wired to client specific selectors in order to fetch the value of the feature flag dynamically
  - If `true`, Account syncing will stop pushing new data to the user storage and only act as an account restoration method that will be fired before multichain account syncing for legacy compatibility
  - This is done because `AccountTreeController` will become responsible for Multichain Account syncing

### Removed

- Unused `UserStorageController:saveInternalAccountToUserStorage` public method
```

Subject: [PATCH 0707/1148] feat(account-tree-controller): add persistent
 metadata for account groups and wallets (#6221)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR adds persistence capabilities to the `AccountTreeController` to
support user customizations like custom names, pinning/hiding account
groups, and sync metadata. Previously, the controller was stateless and
would lose all user customizations on each tree rebuild.

### Current State & Problem
The `AccountTreeController` currently rebuilds the account tree from
scratch using rules every time it initializes, resulting in:
- Loss of custom names set by users for wallets and account groups
- No support for pinning/hiding account groups in the UI
- No persistence of sync metadata required for Account Syncing V2
- Poor user experience as customizations don't survive app restarts or
tree rebuilds

### Solution Overview
This implementation adds **persistent metadata storage** with two new
state properties that store user customizations separately from the tree
structure:

- `accountGroupsMetadata: Record<AccountGroupId, AccountGroupMetadata>`
- `accountWalletsMetadata: Record<AccountWalletId,
AccountWalletMetadata>`

### Key Changes

**Persistent State Structure**:
- Added `AccountGroupMetadata` type supporting `name`, `pinned`,
`hidden`, and `lastUpdatedAt` fields
- Added `AccountWalletMetadata` type supporting `name` and
`lastUpdatedAt` fields
- Metadata is stored in dedicated maps indexed by stable IDs

**Enhanced Tree Building Process**:
- Modified existing `#renameAccountWalletIfNeeded()` and
`#renameAccountGroupIfNeeded()` methods to prioritize persisted custom
names
- Customizations are injected during tree construction rather than
requiring separate tree traversals
- Maintains the existing two-phase approach: structure building +
customization application

**New Public Methods**:
- `setAccountGroupName(groupId, name)` - Sets custom name for account
groups
- `setAccountWalletName(walletId, name)` - Sets custom name for wallets
- `setAccountGroupPinned(groupId, pinned)` - Controls group pinning
state
- `setAccountGroupHidden(groupId, hidden)` - Controls group visibility

**Optimization Strategy**:
- Leverages stable wallet/group IDs for O(1) metadata lookups during
tree building
- Avoids expensive tree traversals by applying customizations inline
during construction
- Automatic tree rebuilding when metadata changes to ensure consistency

### Implementation Details

The persistence follows a **metadata overlay pattern** where:
1. Base tree structure is built using existing rules (Entropy → Snap →
Keyring)
2. Persisted customizations are applied during the naming phase if they
exist
3. Default rule-generated names are used as fallbacks
4. All metadata updates trigger automatic tree rebuilds to maintain
consistency

This approach ensures backward compatibility while adding the
persistence layer needed for Account Syncing V2 and advanced UI features
like pinning/hiding.

## References

- Supports Account Syncing V2 metadata requirements (`lastUpdatedAt`
timestamps for conflict resolution)
- Enables pinning and hiding account groups functionality
- Foundation for persistent user customizations across app sessions

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by updating changelogs
for packages I've changed, highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

+- Add persistence support for user customizations ([#6221](https://github.com/MetaMask/core/pull/6221))
+  - New `accountGroupsMetadata` (of new type `AccountTreeGroupPersistedMetadata`) and `accountWalletsMetadata` (of new type `AccountTreeWalletPersistedMetadata`) state properties to persist custom names, pinning, and hiding states.
+  - Custom names and metadata survive controller initialization and tree rebuilds.
+  - Support for `lastUpdatedAt` timestamps for Account Syncing V2 compatibility.
+- Add setter methods for setting custom account group names, wallet names and their pinning state and visibility ([#6221](https://github.com/MetaMask/core/pull/6221))
 - Add `group.type` tag ([#6214](https://github.com/MetaMask/core/pull/6214))

Subject: [PATCH 0708/1148] feat: expose `createMultichainAccountGroup` from
 `MultichainAccountService` (#6238)

## Explanation

This PR adds the already existing

Subject: [PATCH 0710/1148] refactor: address tech debt for chain agnostic
 permission code repeated on extension and mobile codebases (#6225)

## Explanation

While working on [adding Multichain API to Flask on
mobile](https://github.com/MetaMask/metamask-mobile/pull/14756), some
code that is common to the browser extension repository was also created
on the mobile codebase, namely [these permissions
utilities](https://github.com/MetaMask/metamask-mobile/blob/main/app/util/permissions/index.ts)
which are also present in the `extension` [metamask-controller
module](https://github.com/MetaMask/metamask-extension/blob/main/app/scripts/metamask-controller.js):

- `getCaip25PermissionFromLegacyPermissions`
- `requestPermittedChainsPermissionIncremental`

The work proposed in this pull request migrates these common
functionalities onto our `@metamask/chain-agnostic-permissions` package,
so that they can be imported on both `mobile` and `extension` to be
used.

Subject: [PATCH 0712/1148] feat: add helper method to remove empty groups and
 wallets (#6234)

## Explanation

* What is the current state of things and why does it need to change?
Account removal can leave empty nodes in the Account tree controller.
* What is the solution your changes offer and how does it work? My
solution prunes the tree when there is an empty group and/or wallet.

Subject: [PATCH 0713/1148] chore: create network enablement controller (#6028)

## Explanation

The `NetworkEnablementController` is a core implementation of network
enablement functionality that was previously only available in the
extension. This PR moves and expands this functionality from the
extension's NetworkOrder controller to core, enabling network visibility
features across both extension and mobile platforms. It also renames it
to `NetworkEnablementController` to more accurately represent what it
does. Maybe in the future this can be expanded to include other UX
enhancements that don't need to be tightly coupled with the
NetworkController

Key motivations for this change:


Network Enablement Feature: This work is part of the broader Network
Enablement initiative (https://github.com/MetaMask/core/issues/5737).
The controller has been expanded to include enabledNetworkMap state,
allowing us to:

Track which networks are enabled/disabled
Support the new network enablement feature
Code Quality Improvements: The move to core has provided an opportunity
to:

Improve test coverage of the existing network ordering logic
The controller now handles three key aspects:

Network enablement (new functionality. recently introduced on extension)

Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

## References

* Moves functionality from [NetworkOrder
controller](https://github.com/MetaMask/metamask-extension/blob/main/app/scripts/controllers/network-order.ts)
in extension to core
* Part of Network Enablement initiative (#5737)
* Related to ongoing work related to Global Network Selector Removal

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

+# Network Enablement Controller
+
+A MetaMask controller for managing network enablement state across different blockchain networks.
+
+## Overview
+
+The NetworkEnablementController tracks which networks are enabled/disabled for the user and provides methods to toggle network states. It supports both EVM (EIP-155) and non-EVM networks like Solana.
+
+## Installation
+
+```bash
+npm install @metamask/network-enablement-controller
+```
+
+```bash
+yarn add @metamask/network-enablement-controller
+```
+
+## Usage
+
+### Basic Controller Usage
+
+```typescript
+import { NetworkEnablementController } from '@metamask/network-enablement-controller';
+
+// Create controller instance
+const controller = new NetworkEnablementController({
+  messenger,
+  state: {
+    enabledNetworkMap: {
+      eip155: {
+        '0x1': true, // Ethereum mainnet enabled
+        '0xa': false, // Optimism disabled
+      },
+      solana: {
+        'solana:mainnet': true,
+      },
+    },
+  },
+});
+
+// Enable a network
+controller.setEnabledNetwork('0x1'); // Hex format for EVM
+controller.setEnabledNetwork('eip155:1'); // CAIP-2 format for EVM
+controller.setEnabledNetwork('solana:mainnet'); // CAIP-2 format for Solana
+
+// Disable a network
+controller.setDisabledNetwork('0xa');
+
+// Check if network is enabled
+const isEnabled = controller.isNetworkEnabled('0x1');
+
+// Get all enabled networks for a namespace
+const evmNetworks = controller.getEnabledNetworksForNamespace('eip155');
+
+// Get all enabled networks across all namespaces
+const allNetworks = controller.getAllEnabledNetworks();
+```
+
+### Using Selectors (Redux-style)
+
+The controller also provides selectors that can be used in Redux contexts or any state management system:
+
+```typescript
+import {
+  selectIsNetworkEnabled,
+  selectAllEnabledNetworks,
+  selectEnabledNetworksForNamespace,
+  selectEnabledEvmNetworks,
+  selectEnabledSolanaNetworks,
+} from '@metamask/network-enablement-controller';
+
+// Get controller state
+const state = controller.state;
+
+// Check if a specific network is enabled
+const isEthereumEnabled = selectIsNetworkEnabled('0x1')(state);
+const isSolanaEnabled = selectIsNetworkEnabled('solana:mainnet')(state);
+
+// Get all enabled networks across all namespaces
+const allEnabledNetworks = selectAllEnabledNetworks(state);
+// Returns: { eip155: ['0x1'], solana: ['solana:mainnet'] }
+
+// Get enabled networks for a specific namespace
+const evmNetworks = selectEnabledNetworksForNamespace('eip155')(state);
+const solanaNetworks = selectEnabledNetworksForNamespace('solana')(state);
+
+// Convenience selectors for specific network types
+const enabledEvmNetworks = selectEnabledEvmNetworks(state);
+const enabledSolanaNetworks = selectEnabledSolanaNetworks(state);
+
+// Get total count of enabled networks
+const totalEnabled = selectEnabledNetworksCount(state);
+
+// Check if any networks are enabled for a namespace
+const hasEvmNetworks = selectHasEnabledNetworksForNamespace('eip155')(state);
+```
+
+## API Reference
+
+### Controller Methods
+
+#### `setEnabledNetwork(chainId: Hex | CaipChainId): void`
+
+Enables a network for the user. Accepts either Hex chain IDs (for EVM networks) or CAIP-2 chain IDs (for any blockchain network).
+
+#### `setDisabledNetwork(chainId: Hex | CaipChainId): void`
+
+Disables a network for the user. Prevents disabling the last remaining enabled network.
+
+#### `isNetworkEnabled(chainId: Hex | CaipChainId): boolean`
+
+Checks if a network is currently enabled. Returns false for unknown networks.
+
+#### `getEnabledNetworksForNamespace(namespace: CaipNamespace): string[]`
+
+Gets all enabled networks for a specific namespace.
+
+#### `getAllEnabledNetworks(): Record<CaipNamespace, string[]>`
+
+Gets all enabled networks across all namespaces.
+
+### Selectors
+
+#### `selectIsNetworkEnabled(chainId: Hex | CaipChainId)`
+
+Returns a selector function that checks if a specific network is enabled.
+
+#### `selectAllEnabledNetworks`
+
+Returns a selector function that gets all enabled networks across all namespaces.
+
+#### `selectEnabledNetworksForNamespace(namespace: CaipNamespace)`
+
+Returns a selector function that gets enabled networks for a specific namespace.
+
+#### `selectEnabledNetworksCount`
+
+Returns a selector function that gets the total count of enabled networks.
+
+#### `selectHasEnabledNetworksForNamespace(namespace: CaipNamespace)`
+
+Returns a selector function that checks if any networks are enabled for a namespace.
+
+#### `selectEnabledEvmNetworks`
+
+Returns a selector function that gets all enabled EVM networks.
+
+#### `selectEnabledSolanaNetworks`
+
+Returns a selector function that gets all enabled Solana networks.
+
+## Chain ID Formats
+
+The controller supports two chain ID formats:
+
+1. **Hex format**: Traditional EVM chain IDs (e.g., `'0x1'` for Ethereum mainnet)
+2. **CAIP-2 format**: Chain Agnostic Improvement Proposal format (e.g., `'eip155:1'` for Ethereum mainnet, `'solana:mainnet'` for Solana)
+
+## Network Types
+
+### EVM Networks (eip155 namespace)
+
+- Ethereum Mainnet: `'0x1'` or `'eip155:1'`
+- Optimism: `'0xa'` or `'eip155:10'`
+- Arbitrum One: `'0xa4b1'` or `'eip155:42161'`
+
+### Solana Networks (solana namespace)
+
+- Solana Mainnet: `'solana:mainnet'`
+- Solana Testnet: `'solana:testnet'`
+
+## State Persistence
+
+The controller state is automatically persisted and restored between sessions. The `enabledNetworkMap` is stored anonymously to protect user privacy.
+
+## Safety Features
+
+- **At least one network enabled**: The controller ensures at least one network is always enabled
+- **Unknown network protection**: Prevents enabling networks not configured in the system
+- **Exclusive mode**: When enabling non-popular networks, all other networks are disabled
+- **Last network protection**: Prevents disabling the last remaining enabled network

Subject: [PATCH 0714/1148] fix: dont fetch asset rates when no assets (#6207)

## Explanation

This PR adds an early return in `MultichainAssetsRatesController` when
method is being called with an empty list of assets.

In some situations, for instance when the user sends all their balance
of a given asset, the `MultichainAssetsRatesController` can attempt to
fetch conversions with an empty list of assets. This results in a
validation error crashing the snap (plus an unnecessary network call),
since the [snap validation
structure](https://github.com/MetaMask/snaps/blob/main/packages/snaps-execution-environments/src/common/validation.ts#L312-L323)
expects at least 1 conversion argument.

Subject: [PATCH 0720/1148] feat: expose BridgeController.fetchQuotes method
 (#6236)

## Explanation

This exposes the BridgeController's `fetchQuotes` handler so other
controllers can fetch quotes without reading or updating the
BridgeController's state. This does not publish MixPanel events or
Sentry traces (consumers are responsible for adding these)

Perps quotes are sorted from fastest to slowest

Usage:

```
const quotes: QuoteResponse[] = await BridgeController.fetchQuotes(
  quoteRequestParams
  null, // abortSignal
  FeatureId.PERPS // applies default perps aggIds and noFee param to quote request
)
```

+### Added
+
+- Expose `fetchQuotes` method that returns a list of quotes directly rather than adding them to the controller state. This enables clients to retrieve quotes directly without automatic polling and state management ([#6236](https://github.com/MetaMask/core/pull/6236))

 ### Changed
 
 - Bump `@metamask/keyring-api` from `^19.0.0` to `^20.0.0` ([#6248](https://github.com/MetaMask/core/pull/6248))

Subject: [PATCH 0721/1148] fix defi polling (#6242)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

The polling rate for DeFi is wrongly set to 1 minute instead of 10
minutes. This is just fixing it.

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

Subject: [PATCH 0723/1148] feat(account-tree-controller): add
 `AccountsController:accountRenamed` event handling (#6251)

## Explanation

This PR adds support for handling `AccountsController:accountRenamed`
events in `AccountTreeController` to maintain compatibility with both
legacy account syncing and the multichain accounts state 1
implementation.

`AccountTreeController` now subscribes to and handles
`AccountsController:accountRenamed` events. When an EVM account is
renamed, the controller automatically updates the corresponding account
group name if the group has a default name pattern ("Account X") but the
account now has a custom name. This ensures that custom account names
are reflected at the group level for better user experience.

This change maintains support for legacy account syncing flows that
depend on programmatic account renames while ensuring
`AccountTreeController` state remains consistent with account renames
even though the UI doesn't use the tree structure yet in multichain
state 1.

Subject: [PATCH 0727/1148] refactor(account-tree-controller): remove
 `wallet.metadata.entropy.index` (#6258)

## Explanation

Removing the `wallet.metadata.entropy.index`. This is mainly used by us
for the naming, and the "order" is the responsibility of the
`KeyringController` mainly, not the `AccountTreeController`.

Subject: [PATCH 0728/1148] fix: enable account-tracker-controller to use
 latest block (#6250)

## Explanation

We have had issues on Mobile where fetching native and ERC balances were
cached as we were never making calls with the latest block number.

Similar to the ERC-20 balance update fix
(https://github.com/MetaMask/core/pull/6197), we will now force a block
tracker update to ensure we grab the latest block before making RPC
calls.

Long term we need to investigate and resolve the mobile block tracker
not updating issue.
- Ideally we should have a single isolated block tracker (per chain)
running to get blocks (either every block or every 20s).

Subject: [PATCH 0730/1148] feat(assets): implement comprehensive balance
 selectors for multichain account groups and wallets (#6235)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR implements the `selectBalancesByAccountGroup` selector and
related balance selectors for the assets-controllers package. The
selectors provide functionality to calculate total balances for account
groups, wallets, and all wallets in the user's selected currency.

> The selectors are written in way such they support both mobile and
extension states so that it is fairly simple to just import the
selectors from the controller and directly use them without creating any
additional adapter selectors.
>
> You can use the seelctor in mobile or extension as follows:
> `useSelector(selectBalanceForAllWallets())`

### Mobile PR (Implementation) :
https://github.com/MetaMask/metamask-mobile/pull/18063

### Current State and Need for Change
Currently, there's no centralized way to calculate total balances for
account groups or wallets across multiple chains and account types. This
makes it difficult for consumers to display aggregated balance
information.

### Solution
The new selectors provide:
- `selectBalanceByAccountGroup` - Calculate total balance for a specific
account group
- `selectBalanceByWallet` - Calculate total balance for all groups in a
wallet
- `selectBalanceForAllWallets` - Calculate total balance across all
wallets
- `selectBalanceForSelectedAccountGroup` - Calculate balance for the
currently selected account group

### Technical Implementation
- Uses reselect for memoization and performance optimization
- Handles mixed account types (EVM + non-EVM) in the same group
- Supports multichain balance aggregation with currency conversion
- Includes fallback handling for missing conversion rates
- Proper TypeScript typing throughout

Subject: [PATCH 0731/1148] fix: Unified Swap can_submit and input_value
 properties (#6254)

## Explanation
Changes
- Require clients to pass in the `can_submit` property when publishing
`QuoteSelected`, `AllQuotesSorted`, `AllQuotesOpened` and
`QuotesReceived` events. The value should indicate whether the CTA
button is enabled
- Rename the InputChanged event's `value` property key to `input_value`

Subject: [PATCH 0732/1148] refactor(account-tree-controller)!: remove
 `AccountTree{Wallet,Group}` in-memory instances (#6265)

## Explanation

This implementation is not good enough to start using it.

We will re-enable this once we have a better solution for those. For the
moment, we will add actions to the controller to be able to fetch
accounts from the selected account group and that should cover most
use-cases for the moment.

They will be replaced by:

 ### Changed
 
 - **BREAKING:** Bump peer dependency `@metamask/account-api` from `^0.3.0` to `^0.9.0` ([#6214](https://github.com/MetaMask/core/pull/6214)), ([#6216](https://github.com/MetaMask/core/pull/6216)), ([#6222](https://github.com/MetaMask/core/pull/6222)), ([#6248](https://github.com/MetaMask/core/pull/6248))
+- **BREAKING:** Remove use of in-memory wallets and groups (`AccountTree{Wallet,Object}`) ([#6265](https://github.com/MetaMask/core/pull/6265))
+  - Those types are not ready to be used and adds no value for now.
 - **BREAKING:** Move `wallet.metadata.type` tag to `wallet` node ([#6214](https://github.com/MetaMask/core/pull/6214))
   - This `type` can be used as a tag to strongly-type (tagged-union) the `AccountWalletObject`.
 - Defaults to the EVM account from a group when using `setSelectedAccountGroup` ([#6208](https://github.com/MetaMask/core/pull/6208))

+- Add `AccountTreeController:getAccountsFromSelectedAccountGroup` action ([#6266](https://github.com/MetaMask/core/pull/6266))
+  - This action can be used to get all accounts from the currently selected account group.
+  - This action also support `AccountSelector` support to filter out accounts based on some criterias.
 - Add `AccountTreeGroup.{get,select}` selectors ([#6248](https://github.com/MetaMask/core/pull/6248))
 - Add persistence support for user customizations ([#6221](https://github.com/MetaMask/core/pull/6221))
   - New `accountGroupsMetadata` (of new type `AccountTreeGroupPersistedMetadata`) and `accountWalletsMetadata` (of new type `AccountTreeWalletPersistedMetadata`) state properties to persist custom names, pinning, and hiding states.

Subject: [PATCH 0737/1148] chore: relax yarn constraints for peer dep <1.0.0
 (#6274)

## Explanation

Our `yarn constraints` is a bit too strict when developing new packages
which can be considered "unstable" (version `<1.0.0`).

With the current contraints, it's not possible to depend on an specific
minor/patch version of such package when developing new features (since
the `peerDependencies` would automatically be fixed up to `^0.0.0` to
match our current contraints).

This PR only forces `peerDependencies` to reference a major version only
for peer dependencies with a version `>=1.0.0`.

Subject: [PATCH 0741/1148] fix: hardcode xchain swaps action_type to
 swapbridge_v1 (#6270)

## Explanation

The `action_type` property indicates whether an event is published
before or after the Unified swaps+bridge launch. This change hardcodes
`swapbridge_v1` for all future events

Subject: [PATCH 0743/1148] fix: Update `unsubscribe` type to support selector
 subscriptions (#6262)

## Explanation

The `unsubscribe` type signature has been updated to allow passing in
event handlers for subscriptions that use a selector function. This was
missed when the selector feature was added.

## References

Fixes #6200

Subject: [PATCH 0744/1148] chore: Fix internal type mismatch (#6264)

## Explanation

Fix a type mismatch between the `subscribe` method and the override for
it that accepts a selector. This didn't cause a type error and it
doesn't impact users of this package, but leaving this unresolved left
us at risk because we're type checking with the wrong parameter type.

Subject: [PATCH 0746/1148] chore: remove usages of NetworkController:getState
 in EarnController (#6153)

## Explanation

[The Global Network Selector is being
removed](https://github.com/MetaMask/core/issues/5737) and these changes
for the EarnController ensure that we are not relying on global state
via `NetworkController:getState`. Instead, information required such as
the selected network client ID or chain ID is passed in contextually.

- Removes `NetworkController:getState`. Instead:
- EarnController requires `selectedNetworkClientId` to be passed in when
constructed and it is used in `initializeSDK`.
- Optional `chainId` parameter with fallback to Ethereum Mainnet used in
Pooled Staking data calls: `refreshPooledStakingVaultApyAverages`,
`refreshPooledStakingVaultDailyApys`,
`refreshPooledStakingVaultMetadata` and `refreshPooledStakes`
- Compulsory `chainId` parameter required in all Lending transaction
calls: `executeLendingTokenApprove`, `executeLendingWithdraw` and
`executeLendingDeposit`
- Compulsory `chainId` parameter required in Lending data
calls:`getLendingMarketDailyApysAndAverages`
and`getLendingPositionHistory`. The other Lending data fetches do not
require a chainId.
- Uses `NetworkController:networkDidChange` rather than
`NetworkController:stateChange` as this is a [more granular and less
frequent](https://github.com/MetaMask/core/blob/b09ed6fc26d8809c4a766d1d80623f606447ffa8/docs/controller-guidelines.md?plain=1#L908)
event to listen to.
- Updates tests

 ## [Unreleased]
 
+### Added
+
+- **BREAKING:** Added mandatory parameter `selectedNetworkClientId` to `EarnController` constructor ([#6153](https://github.com/MetaMask/core/pull/6153))
+- **BREAKING:** Added mandatory `chainId` parameter to `executeLendingTokenApprove`, `executeLendingWithdraw`, `executeLendingDeposit`, `getLendingMarketDailyApysAndAverages` and `getLendingPositionHistory` methods ([#6153](https://github.com/MetaMask/core/pull/6153))
+- **BREAKING:** Changed `refreshPooledStakingVaultDailyApys` to accept an options object with `chainId`, `days`, and `order` properties, where `chainId` is a new option, instead of separate parameters `days` and `order` ([#6153](https://github.com/MetaMask/core/pull/6153))
+- Added optional `chainId` parameter to `refreshPooledStakingVaultApyAverages`, `refreshPooledStakingVaultMetadata` and `refreshPooledStakes` (defaults to Ethereum) ([#6153](https://github.com/MetaMask/core/pull/6153))

Subject: [PATCH 0753/1148] Add `error` property to "degraded" events (#6188)

We would like to start tracking the HTTP status code in metrics when the
`NetworkController:rpcEndpointDegraded` event is published because the
maximum number of retries for a request has been exceeded. The HTTP
status is stored in the error that Cockatiel captures, so we just need
to include it in the event payload.

Subject: [PATCH 0755/1148] feat: social login authentication state (#6288)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR adds new persisted state value,
`isSeedlessOnboardingUserAuthenticated` to determine whether the user
has successfully finished social login and TOPRF Authentication.
This is mainly for the UI state in the clients (extension/mobile) and to
avoid querying the sensitive controller state data from the client side
for determining the social login authentication state.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

Subject: [PATCH 0756/1148] chore: Add `clearSubscriptions` test and reorganize
 (#6293)

## Explanation

A new test case has been added for `clearSubscriptions` to improve
functional test coverage. Additionally, the tests for
`clearEventSubscriptions` and `clearSubscriptions` have been grouped in
`describe` blocks to better match our test conventions.

## References

This was extracted from #6132

Subject: [PATCH 0757/1148] chore: Refactor subscription metadata (#6294)

## Explanation

The internal event subscription state has been refactored to include a
metadata object, rather than just an optional selector function. This
will let us add additional metadata later when it is required.
Additional inline comments have been added as well.

This has no functional changes.

Note that these changes have intentionally only been made in the
`messenger` package, not `base-controller`. This refactor was done in
support of future changes that will only be in the `messenger` package.

## References

This was extracted from #6132, which does require an additional metadata
property.

Subject: [PATCH 0759/1148] feat: calculate effective gasFee for swap and
 bridge quotes (#6295)

## Explanation
- read the `effectiveGas` amounts from EVM quotes and use that to
recommend a quote
- update `totalNetworkFee` logic to use the effective gas (after
refunds) instead of the gasLimit
- clients should, display the `totalNetworkFee`, but use the
`totalMaxNetworkFee` value to determine whether the user has sufficient
funds for gas

+- **BREAKING** Added the `effective`, `max` and `total` keys to the `QuoteMetadata.gasFee` type ([#6295](https://github.com/MetaMask/core/pull/6295))
+- Response validation for the QuoteReponse.trade.effectiveGas field ([#6295](https://github.com/MetaMask/core/pull/6295))

+  - The `totalNetworkFee` should be displayed along with the client quotes

 - **BREAKING** Remove `getActionType` export and hardcode `action_type` to `swapbridge-v1`. Deprecate `crosschain-v1` MetricsActionType because it shouldn't be used after swaps and bridge are unified ([#6270](https://github.com/MetaMask/core/pull/6270))

 - Bump `@metamask/multichain-network-controller` from `^0.11.0` to `^0.11.1` ([#6273](https://github.com/MetaMask/core/pull/6273))
 - Bump `@metamask/base-controller` from `^8.0.1` to `^8.1.0` ([#6284](https://github.com/MetaMask/core/pull/6284))

feat: create new utility function to fetch balances for multiple account
addresses

## Explanation

### Current State
The existing multicall functionality only provided basic contract call
batching using the `tryAggregate` function. When applications needed to
fetch token balances for multiple addresses and tokens, they had to make
individual calls or create their own batching logic, leading to
inefficient RPC usage and slower user experiences.

### Solution
This PR introduces a new specialized utility function
`getTokenBalancesForMultipleAddresses` that leverages Multicall3's
`aggregate3` function to efficiently batch balance queries for multiple
token addresses and user addresses in a single operation.

**Key additions:**

1. **`aggregate3` function**: A new lower-level function that provides
direct access to Multicall3's `aggregate3` method, allowing for more
granular control over batch calls with individual failure handling.

2. **`getTokenBalancesForMultipleAddresses` function**: The main utility
that:
- Fetches ERC20 token balances for multiple tokens and addresses in a
single batch
   - Optionally includes native token balances (mapped to zero address)
- Automatically handles call encoding/decoding for both ERC20
`balanceOf` and Multicall3 `getEthBalance`
   - Processes up to 300 calls per batch to avoid gas/size limits

3. **Comprehensive fallback support**:
- Falls back to individual balance calls when Multicall3 is not
supported on a chain
- Uses `eth_getBalance` for native token balances when multicall fails
- Maintains the same interface regardless of the underlying
implementation

4. **Helper functions**:
- `createERC20BalanceCalls`: Generates encoded balance calls for ERC20
tokens
- `createNativeTokenBalanceCalls`: Generates encoded calls for native
token balances
   - `processBalanceResults`: Decodes and organizes the batch results
- `getNativeBalancesFallback`: Handles native balance fetching for
unsupported chains

### Technical Details
- Supports all chains where Multicall3 is deployed (extensive chain
support already configured)
- Returns a nested object structure: `Record<tokenAddress,
Record<userAddress, BN>>`
- Native token balances are accessible via the zero address key
- Includes proper error handling and logging for debugging
- Maintains backwards compatibility with existing multicall
functionality

## References

This enhancement will significantly improve performance for applications
that need to:
- Display portfolio balances across multiple tokens
- Batch balance checks for multiple user addresses
- Reduce RPC calls when fetching balance data

Subject: [PATCH 0762/1148] feat(account-tree-controller): fallback naming for
 newly created groups (#6246)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

**Problem:**
When creating new account groups/wallets, naming fails because the
rule-based logic depends on existing accounts that don't exist yet for
new wallets.

**Solution:**
Added fallback naming logic that generates "Account 1", "Account 2",
etc. within each wallet when rule-based naming returns empty strings.

The strategy we agreed upon prescribes "indexes per wallet":
- Wallet 1 → Account 1, Account 2
- Wallet 2 → Account 1, Account 2

**Changes:**
- Added `#getFallbackAccountGroupName()` method to
`AccountTreeController`
- Modified `#applyAccountGroupMetadata()` to use fallback when
rule-based naming fails
- Added test coverage for the fallback logic

## References

Fixes naming bug reported by @monte.lai for new account groups/wallets:

Subject: [PATCH 0763/1148] feat: Add messenger `delegate` and `revoke` methods
 (#6132)

## Explanation

The methods `delegate` and `revoke` have been added to the Messenger
class. These methods replace the need for the `RestrictedMessenger`. The
`getRestricted` method, and the `RestrictedMessenger` class, have been
removed as obsolete.

Note that the `parent` constructor parameter described in the ADR is not
implemented yet, that will come in the next PR.

## References

See this ADR PR for details: MetaMask/decisions#53
Relates to #5626

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

 ### Added
 
 - Migrate `Messenger` class from `@metamask/base-controller` package ([#6127](https://github.com/MetaMask/core/pull/6127))
+- Add `delegate` and `revoke` methods ([#6132](https://github.com/MetaMask/core/pull/6132))
+  - These allow delegating or revoking capabilities (actions or events) from one `Messenger` instance to another.
+  - This allows passing capabilities through chains of messengers of arbitrary length
+  - See this ADR for details: https://github.com/MetaMask/decisions/blob/main/decisions/core/0012-messenger-delegation.md
 
 ### Changed
 
+- **BREAKING:** Add `Namespace` type parameter and required `namespace` constructor parameter ([#6132](https://github.com/MetaMask/core/pull/6132))
+  - All published events and registered actions should fall under the given namespace. Typically the namespace is the controller or service name. This is the equivalent to the `Namespace` parameter from the old `RestrictedMessenger` class.
+- **BREAKING:** The `type` property of `ActionConstraint` and `EventConstraint` is now a `NamespacedName` rather than a string ([#6132](https://github.com/MetaMask/core/pull/6132))
 - Add default for `ReturnHandler` type parameter of `SelectorEventHandler` and `SelectorFunction` ([#6262](https://github.com/MetaMask/core/pull/6262), [#6264](https://github.com/MetaMask/core/pull/6264))
 
+### Removed
+
+- **BREAKING:** Remove `RestrictedMessenger` class ([#6132](https://github.com/MetaMask/core/pull/6132))
+  - Existing `RestrictedMessenger` instances should be replaced with a `Messenger`. We can now use the same class everywhere, passing capabilities using `delegate`.
+  - See this ADR for details: https://github.com/MetaMask/decisions/blob/main/decisions/core/0012-messenger-delegation.md
+
 ### Fixed
 
 - Update `unsubscribe` type signature to support selector event handlers ([#6262](https://github.com/MetaMask/core/pull/6262))

Subject: [PATCH 0765/1148] fix: ledger txs for swap and bridge (#6302)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR ports the changes from an earlier patch into the
`BridgeStatusController`. It fixes an issue where the user would be
unable to submit Ledger txs on Mobile.

Subject: [PATCH 0767/1148] Reduce global Jest timeout to 5 seconds (#6304)

Currently, the global Jest timeout is 30 seconds. This was probably
changed because some tests are complicated and may take a long time to
resolve. But most tests are not this way, and using a large timeout
leads to a poor developer experience.

Subject: [PATCH 0768/1148] feat: Add Messenger `parent` parameter (#6142)

## Explanation

Add the `parent` constructor parameter to the `Messenger` class for
automatic delegation of all capabilities under that messenger's
namespace. This significantly reduces boilerplate, making the messenger
easier to use in a similar manner to how the old `RestrictedMessenger`
class wored.

See this ADR PR for details: MetaMask/decisions#53

## References

Depends upon #6132
Relates to #5626

Subject: [PATCH 0769/1148] fix: Unified swaps quote errors and tx event
 properties (#6299)

## Explanation

This fixes multiple MixPanel events

- Ignore error messages thrown when quote requests are cancelled. This
prevents the `QuoteError` event from being published when an error is
expected
- Parse destination amount from Swap tx receipt and use it to calculate
finalized tx event properties
- Use `status.destChain.amount` from getTxStatus response to calculate
actual bridged amount

Subject: [PATCH 0772/1148] feat: use aggregate3 or accountAPI to fetch
 balances (#6232)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

You're absolutely right! Let me update that section to be more precise
about the fallback strategy:

## Explanation

### Current State and Problem
Previously, the TokenBalancesController fetched token balances using
individual RPC calls for each token-account combination. This approach
was inefficient and slow, especially for users with multiple accounts
and many tokens across different networks. Each balance check required a
separate `balanceOf` call, leading to:

- High number of RPC requests
- Slower balance updates
- Potential rate limiting issues
- Poor user experience during balance refreshes

### Solution
This PR implements a **two-tier balance fetching strategy** with
intelligent fallback:

1. **Primary**: **Accounts API** - Uses MetaMask's external API service
for supported networks (faster, more efficient)
2. **Fallback**: **RPC with Aggregate3** - Uses Multicall3's
`aggregate3` function for efficient batch RPC calls when:
   - The chain is not supported by the Accounts API
   - The Accounts API service is unavailable or fails
   - Any other API-related errors occur

### Key Technical Changes

#### Smart Fallback Architecture
- `TokenBalancesController` first attempts to fetch balances via the
**Accounts API** for supported networks
- For chains **not supported by the API** or when the **API fails**, it
automatically falls back to **RPC calls using `aggregate3`**
- Successfully processed chains are removed from subsequent fetchers,
ensuring no duplicate work
- Each fetcher only processes chains it can handle

#### Accounts API Integration
- Leverages MetaMask's backend infrastructure for faster balance
retrieval
- Supports a curated list of networks
(`SUPPORTED_NETWORKS_ACCOUNTS_API_V4`)
- Handles multi-account and multi-chain requests efficiently

#### Aggregate3 Fallback Implementation
When the Accounts API can't handle certain networks, the system uses
Multicall3's `aggregate3` function to:
- Batch multiple `balanceOf` calls into a single RPC request
- Handle both ERC20 token balances and native token balances
- Support staking contract balance queries
- Process results efficiently with individual failure handling

#### Performance Optimizations
- **API-first strategy**: Fastest possible retrieval for supported
networks
- **Efficient RPC fallback**: Up to 300 calls per batch to avoid
gas/size limits when API isn't available
- **Serial batch execution**: Processes batches sequentially to prevent
overwhelming the RPC
- **Smart chain routing**: Each chain uses the most appropriate fetching
method
- **Selective updates**: Only updates state when balance changes are
detected

### Technical Details

The fallback mechanism ensures comprehensive network coverage:
- **Supported networks** → Accounts API (fastest)
- **Unsupported networks or API failures** → RPC with `aggregate3`
(still much faster than individual calls)

The `aggregate3` function provides significant improvements over
individual RPC calls:
- Each call can fail individually without affecting others
(`allowFailure: true`)
- Supports different call types (ERC20, native, staking) in the same
batch
- Automatically falls back to individual calls if multicall fails
entirely

### Impact
- **Optimal performance**: Uses fastest available method for each
network
- **Complete network coverage**: No network is left without efficient
balance fetching
- **Reduced RPC calls**: For non-API networks, reduces from N individual
calls to 1 call per batch of up to 300 operations
- **Better reliability**: Multiple fetching strategies ensure balance
data is always available
- **Graceful degradation**: Seamless fallback when services are
unavailable

## References

Addresses performance issues with token balance fetching by implementing
Accounts API integration with aggregate3 RPC fallback for comprehensive
and efficient balance retrieval across all networks.

Subject: [PATCH 0774/1148] Revert releases 502.0.0 and 503.0.0 (#6320)

Release 502.0.0 contained some extra changes to the dependencies for
`assets-controllers` that need to be reverted. Release 503.0.0 was
created with the (reasonable) assumption that 502.0.0 had already been
deployed. We need to revert both and then recreate 503.0.0 as 502.0.0.

   - Falls back to RPC calls using Multicall3's `aggregate3` for unsupported networks or API failures

Subject: [PATCH 0776/1148] feat(assets): implement balance change calculator
 and network filtering (#6285)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

The PR introduces change to remove the centralized selectors and instead
places a centralized calculation logic that clients can use to create
their own selectors.

- Current: aggregated percent/amount change for balances lives in client
selectors with platform-specific nuances.
- Change: introduce a pure calculator to centralize portfolio change
computation and move the logic out of selectors. Callers
(mobile/extension) can now request 1d/7d/30d change consistently.
- Details:
- EVM: uses TokenRatesController.marketData price and
pricePercentChange{1d|7d|30d}, converted via CurrencyRateController.
- Non‑EVM: uses MultichainAssetsRatesController.conversionRates with
marketData.pricePercentChange.{P1D|P7D|P30D}.
- Previous totals reconstructed via current / (1 + percent/100); amount
and percent change computed from that.
- Honors enabled-network filtering map (same semantics as totals
calculation).

 ### Added
 
+- Implement balance change calculator and network filtering ([#6285](https://github.com/MetaMask/core/pull/6285))
+  - Add core balance change calculators with period support (1d/7d/30d), network filtering, and group-level computation
 - Add new utility functions for efficient balance fetching using Multicall3 ([#6212](https://github.com/MetaMask/core/pull/6212))
   - Added `aggregate3` function for direct access to Multicall3's aggregate3 method with individual failure handling
   - Added `getTokenBalancesForMultipleAddresses` function to efficiently batch ERC20 and native token balance queries for multiple addresses

Subject: [PATCH 0778/1148] fix: add init function for network-enablement
 controllers (#6329)

## Explanation

This PR adds an init function to the network-enablement controllers,
initializing them from the network configuration. It also listens for
the transaction:submitted event and enables the relevant network so
users can immediately see the submitted transaction and their assets.

Subject: [PATCH 0779/1148] feat: add alignment methods to group, wallet and
 service classes (#6326)

## Explanation

**What is the current state of things and why does it need to change?**
An alignment mechanism didn't exist for multichain account groups. It
needs to be added because we can have multiple scenarios where
misalignment occurs:
1. State 1 -> State 2 - We will have to align existing account groups
when they are created.
2. New protocols added - Existing groups will have to have an account
associated with the new provider (chain).
3. Basic functionality toggle - With basic functionality off, we can
have a scenario where only an EVM account is created when a group is
created.
4. Discovery - When importing an SRP, the discovery process might not
necessarily yield a discovered account for every provider and we have to
align the group in those scenarios.

**What is the solution your changes offer and how does it work?** It
adds an alignment mechanism at the group level and it runs through the
list of providers and checks to see if any accounts exist for that
particular group, if there aren't any, then it calls
`provider.createAccounts` with the associated entropy id and group
index. Alignment methods were added at the wallet level where a wallet
would call align on all of its existing groups and similarly at the
service level where it can call align on all of its wallets. Singular
methods were also added at the wallet and service level where a
particular group associated with a wallet can be aligned and a
particular wallet can be aligned by the service.

Note: I also refactored the `withCreateAccount` in `SnapAccountProvider`
to be a bit more readable and easier to understand.

Subject: [PATCH 0783/1148] feat: Export helper messenger types (#6317)

## Explanation

These types are useful in migrating the `@metamask/base-controller`
package to use the new messenger package. They will eventually replace
the `ExtractAvailableAction` and `ExtractAvailableEvent` types in
`./packages/base-controller/tests/helpers.ts` that we use in various
tests.

Subject: [PATCH 0784/1148] feat: Create new experimental `next` export (#6316)

## Explanation

This export will be used to test upcoming breaking changes for the
`@metamask/base-controller` package related to #5626.

This duplicate copy of the BaseController class is currently identical
to the main one (except for the import path for the Messenger classes),
but future PRs will add further changes. The messenger classes have been
omitted, as they will be removed in the upcoming breaking change as we
switch to using `@metamask/messenger` instead.

Subject: [PATCH 0785/1148] fix: Resolve precision loss in AccountsAPI balance
 conversion causing zero balances (#6330)

## Explanation

**Problem**

Token balances were incorrectly showing as 0x0 in the
TokenBalancesController state when fetched via the AccountsAPI, despite
the API returning correct non-zero balance values. This affected tokens
with decimal amounts, particularly those with high precision values.

**Example:**

API returns: "balance": "568013.300780982071882412" (PEPE token, 18
decimals)
State shows: "0x25d887Ce7a35172C62FeBFD67a1856F20FaEbB00": "0x0"

**Root Cause**

The issue was in AccountsApiBalanceFetcher.ts where balance conversion
used floating-point arithmetic:

```
// Problematic code
value = new BN((parseFloat(b.balance) * 10 ** b.decimals).toFixed(0));
```
This approach suffers from JavaScript floating-point precision
limitations:
`parseFloat("568013.300780982071882412") * 10^18 loses precision`
Large numbers with many decimal places get rounded incorrectly
Results in zero or incorrect values when converted to BigNumber
Solution
Replaced floating-point arithmetic with string-based BigNumber
conversion

Subject: [PATCH 0786/1148] feat: Default action/event type params to never
 (#6311)

## Explanation

The action and event type parameters for the new `@metamask/messenger`
package's Messenger class now default to `never`. This should make it
harder to accidentally create a messenger with overly broad inferred
types, making it less type safe than the author might expect.

The `Messenger` classes in `@metamask/base-controller` were not changed
to avoid breaking changes. While this change itself wouldn't really be
breaking by most definitions, it would require changes due to our use of
the `@typescript-eslint/no-unnecessary-type-arguments` lint rule.

Subject: [PATCH 0788/1148] chore(keyring-controller): remove QRKeyring-related
 code (#6031)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
Dependent on:
  - ~~https://github.com/MetaMask/accounts/pull/60~~

This PR removes all code related to the QRKeyring from KeystoneHQ, which
we intend to deprecate in favor of the new QRKeyring implementation in
the MetaMask accounts monorepo, that fully supports our Keyring type.

+- **BREAKING:** Removed QR keyring methods ([#6031](https://github.com/MetaMask/core/pull/6031))
+  - The following methods have been removed:
+    - `cancelQRSignRequest`
+    - `cancelQRSynchronization`
+    - `connectQRHardware`
+    - `forgetQRDevice`
+    - `getOrAddQRKeyring`
+    - `getQRKeyring`
+    - `getQRKeyringState`
+    - `resetQRKeyringState`

+    - `submitQRCryptoHDKey`
+    - `submitQRCryptoAccount`
+    - `submitQRSignature`
+    - `unlockQRHardwareWalletAccount`
+  - Consumers can use the `withKeyring` method to select a QR keyring and execute a callback with it as argument.
+- **BREAKING:** Removed `KeyringController:qrKeyringStateChange` event ([#6031](https://github.com/MetaMask/core/pull/6031))

Subject: [PATCH 0789/1148] controller-level selector for all tokens (#6226)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Adds new selector for list of tokens and balances based on the selected
account group id (BIP44, works with stage 1).

Selectors are made with the same pattern used for controller-level
BridgeController selectors.

 ### Added
 
-- `UserStorageController` optional config callback `getIsMultichainAccountSyncingEnabled`, and `getIsMultichainAccountSyncingEnabled` public method / messenger action
+- `UserStorageController` optional config callback `getIsMultichainAccountSyncingEnabled`, and `getIsMultichainAccountSyncingEnabled` public method / messenger action ([#6215](https://github.com/MetaMask/core/pull/6215))
   - This callback needs to be wired to client specific selectors in order to fetch the value of the feature flag dynamically
   - If `true`, Account syncing will stop pushing new data to the user storage and only act as an account restoration method that will be fired before multichain account syncing for legacy compatibility
   - This is done because `AccountTreeController` will become responsible for Multichain Account syncing

Subject: [PATCH 0791/1148] feat: Migrate `next` BaseController class to new
 Messenger package (#6318)

## Explanation

Migrate the upcoming `BaseController` class to use the new
`@metamask/messenger` package. This includes replacing
`RestrictedMessenger` with the new `Messenger` class that supports
delegation.

## References

Relates to https://github.com/MetaMask/core/issues/5626

- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0794/1148] fix: inaccurate swap Submitted event properties
 (#6314)

## Explanation

Changes
- Update the implementation of `UnifiedSwapBridgeEventName.Submitted` to
require event publishers to provide all properties. This is in needed
because the Submitted event can be published after the
BridgeController's state has been reset
- Parse event properties from the quote request if an event needs to be
published prior to tx submission (i.e., Failed, Submitted)
- Calculate `actual_time_minutes` event property based on `txMeta.time`
if available

Subject: [PATCH 0796/1148] feat: add gator permissions controller (#6033)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

### @metamask/gator-permissions-controller

#### Current State and Why Change is Needed

MetaMask clients currently lack a dedicated system for managing gator
permissions that are stored to profile sync via the
`@metamask/gator-permissions-snap`.

#### Solution and How It Works

This change introduces a new `@metamask/gator-permissions-controller`
package that provides a comprehensive solution for managing gator
permissions in MetaMask clients with gator-snap integration.

#### Changes That Might Not Be Obvious

- Serialization Strategy: The controller `state` uses JSON serialization
for storing permission data fetched from
`@metamask/gator-permissions-snap`, which allows for efficient storage
and retrieval while maintaining data integrity. The deserialize
permission data is represented as a list of gator permissions filtered
by permission type and chainId.
- Default Permission Structure: The controller initializes with an empty
structure for all three permission types, ensuring consistent state even
when no permissions are configured

####  Package Dependencies and Integration

The new package depends on `@metamask/snaps-controllers` as a peer
dependency, ensuring it can leverage sending RPC requests to an
installed Metamask Snap. This integration allows the
`GatorPermissionsController` to forward requests to
`@metamask/gator-permissions-snap` to fetch users' Gator permissions
that have been stored in the MetaMask Profile Sync service.

The `@metamask/gator-permissions-snap` will take on the responsibility
of authenticating with MetaMask Profile Sync service using an`SRP`
identifier via integration with `@metamask/message-signing-snap`.

#### No Dependency Upgrades Required

This is a new package that introduces new functionality without
requiring changes to existing dependencies. The package uses the current
stable versions of `@metamask/base-controller`, `@metamask/utils
`,`@metamask/snaps-sdk`, and `@metamask/snaps-utils` following the
established patterns in the MetaMask codebase.

+# `@metamask/gator-permissions-controller`
+
+A dedicated controller for reading gator permissions from profile sync storage. This controller fetches data from the encrypted user storage database and caches it locally, providing fast access to permissions across devices while maintaining privacy through client-side encryption.
+
+## Installation
+
+`yarn add @metamask/gator-permissions-controller`
+
+or
+
+`npm install @metamask/gator-permissions-controller`
+
+## Usage
+
+### Basic Setup
+
+```typescript
+import { GatorPermissionsController } from '@metamask/gator-permissions-controller';
+
+// Create the controller
+const gatorPermissionsController = new GatorPermissionsController({
+  messenger: yourMessenger,
+});
+
+// Enable the feature (requires authentication)
+gatorPermissionsController.enableGatorPermissions();
+```
+
+### Fetch from Profile Sync
+
+```typescript
+const permissions =
+  await gatorPermissionsController.fetchAndUpdateGatorPermissions();
+```

 - Update the implementation of `UnifiedSwapBridgeEventName.Submitted` to require event publishers to provide all properties. This is in needed because the Submitted event can be published after the BridgeController's state has been reset ([#6314](https://github.com/MetaMask/core/pull/6314))

 ## [Unreleased]
 
+### Added
+
+- Add `getBridgeHistoryItemByTxMetaId` method to retrieve bridge history items by their transaction meta ID ([#6346](https://github.com/MetaMask/core/pull/6346))
+- Add support for EIP-7702 gasless transactions in transaction batch handling ([#6346](https://github.com/MetaMask/core/pull/6346))
+
 ### Changed
 
 - Calculate `actual_time_minutes` event property based on `txMeta.time` if available ([#6314](https://github.com/MetaMask/core/pull/6314))
 - Parse event properties from the quote request if an event needs to be published prior to tx submission (i.e., Failed, Submitted) ([#6314](https://github.com/MetaMask/core/pull/6314))
+- Update transaction batch handling to conditionally enable EIP-7702 based on quote's `gasless7702` flag ([#6346](https://github.com/MetaMask/core/pull/6346))

Subject: [PATCH 0801/1148] Document recent breaking change to controller-utils
 (#6343)

Commit 5e541a266d268d0306b1eac72fd25b47cb307adb introduced inadvertent
breaking changes to `controller-utils` and `network-controller`.
Specifically:

- `createServicePolicy` returns an object with type `ServicePolicy`, and
this object has an `onDegraded` method on it. Previous to this commit,
the event listener that `onDegraded` took expected no arguments, but the
commit changed the signature of the listener such that it now expected
either no arguments _or_ an object with either an `error` or `value`
property.
- The `AbstractRpcService` type in `network-controller` builds on
`ServicePolicy` for its `on*` hooks. That means that this commit also
changed the signature of the listener for `onDegraded` so it now
expected an object with either `endpointUrl`, `error` + `endpointUrl` or
`value` + `endpointUrl`.

For posterity, we discovered these breaking changes within
`eth-json-rpc-middleware`. This package contains a copy of
`AbstractRpcService`, and we found that it was not compatible with
`network-controller` when upgrading its dependency on `controller-utils`
to the newest version.

Re-releasing these breaking changes under major versions would be
painful as it would affect nearly all packages under the `core`
monorepo. So instead, we merely document them in the changelogs here.

Subject: [PATCH 0804/1148] feat(authentication-controller): prevent login race
 conditions (#6353)

## Explanation

This PR adds a deferred login mechanism to `SRPJwtBearerAuth` that
prevents race conditions when multiple concurrent authentication
attempts occur. The implementation uses Promise caching to ensure only
one login operation executes at a time, with subsequent concurrent calls
sharing the same Promise result.

Changes:

- Extract login logic into dedicated `#performLogin` method
- Add `#deferredLogin` method with Promise map caching for race
condition prevention

Subject: [PATCH 0805/1148] chore: Update Jest config to map `next` export to
 source correctly (#6349)

## Explanation

Tests that used the `@metamask/base-controller/next` export were not
working correctly until after a build was completed. They were using the
built code rather than the source code. On CI the tests run without any
build, so they would always fail.

This was resolved up updating the TSConfig and Jest config to map the
`next` export to the correct source code.

This unblocks #6335 as well as other controller migrations to the
upcoming BaseController version.

Subject: [PATCH 0808/1148] fix: token selector issues (#6358)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

The format for EVM addresses for AccountTrackerController in mobile
differs from extension and from the other controller states. This was
causing it to miss native account balances.

It also uses the correct internal account type in the assets, so that
BTC account types can be identified.

Finally, it fixes an issue with the `mergeAssets` function mutating
internal parts of cached objects.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

 ### Changed
 
 - Bump `@metamask/base-controller` from `^8.1.0` to `^8.2.0` ([#6355](https://github.com/MetaMask/core/pull/6355))
+- Uses the correct internal account type for the asset ([#6358](https://github.com/MetaMask/core/pull/6358)).

Subject: [PATCH 0809/1148] Fix: Normalize token addresses to prevent duplicate
 balance entries (#6354)

## Explanation

The TokenBalancesController.updateBalances function was creating
duplicate entries for the same token when addresses came in different
cases (lowercase vs mixed case). This resulted in token balance state

solution was to normalized all token addresses to lowercase before using
them as object keys

Subject: [PATCH 0810/1148] fix: reduce rpc fetch timeout and batch size
 (#6365)

## Explanation

**Problem**

The `TokenBalancesController` was using `safelyExecuteWithTimeout` which
has a critical flaw: it never throws errors on timeout. Instead, it
silently catches all errors (including timeouts) and returns undefined.
This prevented the controller's catch blocks from executing, breaking
the intended fallback mechanism between different balance fetchers.
Additionally, the timeout was set to 3 minutes (DEFAULT_INTERVAL_MS =
180,000ms), which is excessively long for RPC calls and could lead to
poor user experience.

**Solution**
1. Replace safelyExecuteWithTimeout with Promise.race

- Implemented direct Promise.race that properly throws timeout errors
- Now timeout errors are correctly caught by the existing error handling
logic
- Enables proper fallback between API and RPC balance fetchers

2. Reduce RPC timeout duration

- Added new constant RPC_TIMEOUT_MS = 5000 (5 seconds)
- Reduced timeout from 3 minutes to 5 seconds for better responsiveness
- 5 seconds is sufficient for most RPC calls while still allowing for
network latency with 100 batch size

## Explanation

This PR implements

- the `enableAllPopularNetworks()` to enable all popular networks
- modifies the `enableNetwork()` function to use exclusive behavior,
ensuring only one network is enabled per namespace at a time.

 ## [Unreleased]
 
+### Added
+
+- Add `enableAllPopularNetworks()` method to enable all popular networks and Solana mainnet simultaneously ([#6367](https://github.com/MetaMask/core/pull/6367))
+
 ### Changed
 
+- **BREAKING:** `enableNetwork()` now implements exclusive behavior - disables all other networks in the same namespace before enabling the target network ([#6367](https://github.com/MetaMask/core/pull/6367))
 - Bump `@metamask/base-controller` from `^8.1.0` to `^8.2.0` ([#6355](https://github.com/MetaMask/core/pull/6355))

Subject: [PATCH 0815/1148] Integrate Shield gateway in transaction controller
 (#6281)

## Explanation

For MetaMask Transaction Shield we want to reroute all transaction
simulation requests through a dedicated proxy.
This PR adds the following functionality to the TransactionController to
accomplish that.

- Add optional `getSimulationConfig` parameter to constructor.
- If `getSimulationConfig` parameter is present, call the function to
retrieve a new simulation URL and an authorization header. Replace the
simulation URL and add the authorization header to the simulation
request.

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?

 ## [Unreleased]
 
-### Changed

+
+### Added
 
-- Bump `@metamask/base-controller` from `^8.1.0` to `^8.2.0` ([#6355](https://github.com/MetaMask/core/pull/6355))
-- Uses the correct internal account type for the asset ([#6358](https://github.com/MetaMask/core/pull/6358)).
 - Enable `AccountTrackerController` to fetch native balances using AccountsAPI when `allowExternalServices` is enabled ([#6369](https://github.com/MetaMask/core/pull/6369))
+
   - Implement native balance fetching via AccountsAPI when `useAccountsAPI` and `allowExternalServices` are both true
   - Add fallback to RPC balance fetching when external services are disabled
   - Add comprehensive test coverage for both AccountsAPI and RPC balance fetching scenarios

-- Ensure that the evm addresses used for an internal mapping are always lowercase to avoid mismatches with client format ([#6358](https://github.com/MetaMask/core/pull/6358)).
-- Prevents mutation of memoized fields, which was causing issues ([#6358](https://github.com/MetaMask/core/pull/6358)).

Subject: [PATCH 0819/1148] feat: add batch transaction options (#6368)

## Explanation

Add optional `batchTransactionsOptions` to `TransactionMeta` to specify
which batch modes can be used by any specified `batchTransactions`.

Support optional `isAfter` property in `batchTransactions` to specify
whether dynamically added transactions are executed before or after the
main transaction in the batch.

Handle existing transactions processed by EIP-7702 in
`addTransactionBatch` by re-using nonce and ensuring `onPublish` is
called.

Subject: [PATCH 0821/1148] fix: Add return type annotation to
 `getCaip25PermissionFromLegacyPermissions` (#6382)

## Explanation

This commit enables the return output of
`getCaip25PermissionFromLegacyPermissions` to be assignable to
`RequestedPermissions`.

Because `RequestedPermissions` is defined using `NonEmptyArray`,
assigning `ReturnType<typeof getCaip25PermissionFromLegacyPermissions>`
to `RequestedPermissions` currently results in the following error:

```ts
Type '{ "endowment:caip25": { caveats: { type: string; value: Caip25CaveatValue; }[]; }; }' is not assignable to type 'RequestedPermissions'.
  Property '"endowment:caip25"' is incompatible with index signature.
    Type '{ caveats: { type: string; value: Caip25CaveatValue; }[]; }' is not assignable to type 'Partial<PermissionConstraint>'.
      Types of property 'caveats' are incompatible.
        Type '{ type: string; value: Caip25CaveatValue; }[]' is not assignable to type '[CaveatConstraint, ...CaveatConstraint[]]'.
          Source provides no match for required element at position 0 in target.ts(2322)
```

Subject: [PATCH 0822/1148] feat: publish QuoteValidationFailed and
 StatusValidationFailed events for bridge-api responses (#6362)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Publishes validation failure events for bridge-api responses. This
enables us to proactively monitor validation failure rates and adjust
the backend's responses (or the controller validation) as needed.

Subject: [PATCH 0825/1148] feat: parallelize balance fetch (#6390)

## Explanation

- Improve balance fetching performance and resilience by parallelizing
multi-chain operations and moving timeout handling to fetchers

- Replace sequential `for` loops with `Promise.allSettled` in
`RpcBalanceFetcher` and `AccountTrackerController` for parallel chain
processing
- Move timeout handling from controller-level `Promise.race` to
fetcher-level `safelyExecuteWithTimeout` for better error isolation
- Add `safelyExecuteWithTimeout` to both `RpcBalanceFetcher` and
`AccountsApiBalanceFetcher` to prevent individual chain timeouts from
blocking other chains
- Remove redundant timeout wrappers from `TokenBalancesController` and
`AccountTrackerController`
- Improve test coverage for timeout and error handling scenarios in all
balance fetchers

Subject: [PATCH 0827/1148] feat(multichain-account-service): basic
 functionality management (#6332)

## Explanation

### What is the current state and why does it need to change?

Currently, the `MultichainAccountService` has no mechanism to manage
provider states based on user preferences like the "basic functionality"
toggle. When users disable advanced features (basic functionality OFF),
all providers (EVM, Solana, Bitcoin, etc.) remain active and continue
creating multichain accounts, which goes against the user's preference
for a simplified wallet experience.

The extension's `PreferencesController` manages the basic functionality
toggle (`useExternalServices`), but there was no way to communicate this
state change to the core `MultichainAccountService` to disable
non-essential providers.

### What is the solution and how does it work?

This PR introduces a clean provider state management system that allows
clients to control which providers are active based on user preferences:

1. **Provider-Level Disable Mechanism**: Added `setDisabled(disabled:
boolean)` method to `BaseAccountProvider`. Providers now **can /
should** check `this.isDisabled` in their `createAccounts` methods and
return empty arrays when disabled, preventing new account creation.

2. `EvmAccountProvider` could be disabled, for other reasons in the
future, but does not depend on basic functionality, at all.

3. Added `setBasicFunctionality({ enabled: boolean })` method to
`MultichainAccountService` that:
   - Calls `setDisabled(!enabled)` on all providers
- **Triggers wallet alignment when basic functionality is enabled to
ensure account groups are complete**

4. **Extension Integration**: The extension's `PreferencesController`
now calls this method when the basic functionality toggle changes.

Subject: [PATCH 0828/1148] fix(multichain-account-service): fix account event
 subscription + clear state before re-init service (#6394)

## Explanation

The event subscription has to be moved in the constructor otherwise if
we call `init` multiple times, we will subscribe to those same events
multiple times.

Also, moving those subscriptions on the constructor ensure that the
service will pick up newly added accounts after the service is being
created even if `init` has not been called yet, which seems to be
another bug on the extension given that the service is not initialized
properly after the first on-boarding...

Subject: [PATCH 0834/1148] chore(network-controller): Deprecate
 lookupNetworkByClientId (#6308)

When initializing the globally selected network or switching it to a new
network, we must verify the availability status of the network as well
as its EIP-1559 compatibility. There are two ways to do this in
NetworkController: `lookupNetwork` and `lookupNetworkByClientId`. There
are some slight differences in logic with `lookupNetwork` in how it
handles changes to the globally selected network, but they essentially
do the same thing, and it would make for a less confusing and more
maintainable API if we consolidated them into one method.

Since doing so would be a breaking change, to ease the transition, this
commit deprecates `lookupNetworkByClientId` and suggests that developers
use `lookupNetwork` instead. It also refactors both methods to remove
the duplicate code and ensures that `lookupNetwork` is well-tested both
when given a network client ID and not given one.

Subject: [PATCH 0836/1148] Improve sample-controllers to be more useful
 examples (#6168)

The controllers and services in `sample-controllers` are not as useful
as examples as they could be. They do not follow the best practices that
we want others to follow, so we cannot ask teams to copy them, and they
do not follow patterns that are standard in the product. This commit fixes
that.

+- **BREAKING:** The messenger for `SampleGasPricesController` now expects `NetworkController:getNetworkClientById` to be allowed, and no longer expects `NetworkController:getState` to be allowed ([#6168](https://github.com/MetaMask/core/pull/6168))
+- **BREAKING:** `SampleGasPricesController.updateGasPrices` now takes a required `chainId` option ([#6168](https://github.com/MetaMask/core/pull/6168))
+- `SampleGasPricesController` will now automatically update gas prices when the globally selected chain changes ([#6168](https://github.com/MetaMask/core/pull/6168))
 - Bump `@metamask/base-controller` from `^8.0.1` to `^8.2.0` ([#6284](https://github.com/MetaMask/core/pull/6284), [#6355](https://github.com/MetaMask/core/pull/6355))

+### Removed
+
+- **BREAKING:** `SampleGasPricesController` no longer takes a `gasPricesService` option ([#6168](https://github.com/MetaMask/core/pull/6168))
+  - The controller now expects `SampleGasPricesService` to have been instantiated ahead of time

Subject: [PATCH 0841/1148] feat: emit events on tree updates and group
 selection (#6400)

## Explanation

Adds event emissions to `AccountTreeController` to enable other
controllers to react to state changes. Previously, said controller had
no way to notify consumers when the account tree structure changed or
when the selected account group was updated.

**Solution:**
- Adds `AccountTreeController:accountTreeUpdated` event - emitted when
nodes (wallets, groups, or accounts) are added or removed
- Adds `AccountTreeController:selectedAccountGroupUpdated` event -
emitted when the selected account group changes
- Events are only emitted for structural/selection changes, not metadata
updates (name, pinning, hiding)

This enables other controllers to listen for tree changes and react
accordingly, supporting the upcoming Account Syncing V2 functionality.

Subject: [PATCH 0842/1148] Release/521.0.0 (#6413)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

- Patch release for `@metamask/assets-controllers` with bugfixes that
affect `AccountTrackerController`.

None of the changes require any change to client code in Mobile (which
is the only one using `AccountTrackerController`). They fix three
different balance-related bugs introduced in ^74.

Subject: [PATCH 0845/1148] refactor: cache vault data while unlock (#6205)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
This PR includes some refactors and optimizations of vault operations
(lock/unlock) in the SeedlessOnboarding controller.
- refactor vault unlock/lock (serialize, deserialize, parse)
- cache unlocked vault data in the controller when vault is unlocked, to
avoid multiple crypto operations which are CPU-intensive.

+# Subscription Controller Architecture
+
+## Overview
+
+The Subscription Controller is responsible for managing user subscription lifecycle within MetaMask, including subscription creation, management, and payment processing. It handles both traditional card-based payments and cryptocurrency payments, while maintaining subscription state and coordinating with external services and other MetaMask controllers.
+
+## Core Responsibilities
+
+### 1. Subscription Service Communication
+
+- **Read User Subscription**: Fetch current user subscription data from the subscription service
+- **Remove User Subscription**: Cancel user subscriptions via the subscription service
+- **Update User Subscription**: Modify subscription details (renew, plan changes, billing updates)
+- **Authentication Token Management**: Trigger auth token refresh and validation through user storage controller
+
+### 2. Event-Driven Subscription Management
+
+- **Subscription Change Events**: Listen for user subscription events (subscribe/cancel)
+- **Auth Token Refresh**: Trigger auth token refresh through user storage controller when subscription status changes
+- **Status Synchronization**: Update local subscription status based on service events
+- **Event Broadcasting**: Emit events when subscription status changes and auth token refresh is triggered
+
+### 3. Card-Based Subscription Creation
+
+- **Existing Subscription Check**: Verify if user already has an active subscription
+- **Stripe Integration**: Request hosted checkout URLs from subscription service
+- **Checkout Flow**: Return checkout URLs to UI for user completion
+- **Success Handling**: Update subscription status when payment succeeds
+
+### 4. Cryptocurrency-Based Subscription Creation
+
+- **Balance Verification**: Check user's available crypto balance on supported chains
+- **Transaction Creation**: Generate approval transactions for user signature
+- **Multi-chain Support**: Handle payments across different blockchain networks
+- **Transaction Monitoring**: Track transaction status and update subscription on completion
+
+### 5. Payment Options Management
+
+- **Available Methods**: Determine user's available payment options
+- **Card Support**: Always include card payment as an option
+- **Crypto Support**: Include supported cryptocurrencies based on user's chain balances
+
+### 6. Billing Management
+
+- **Billing Portal Access**: Request Stripe billing portal URLs from subscription service
+- **Subscription Verification**: Ensure user has active subscription before billing access
+
+## Architecture Components
+
+### State Management
+
+```typescript
+interface SubscriptionControllerState {
+  // User subscription information
+  subscriptions: Subscription[];
+
+  // Payment options cache
+  availablePaymentOptions: {
+    cards: boolean;
+    crypto: {
+      [chainId: string]: {
+        [tokenAddress: string]: {
+          symbol: string;
+          balance: string;
+          decimals: number;
+        };
+      };
+    };
+  };
+}
+```
+
+### Controller Dependencies
+
+#### External Services
+
+- **Subscription Service**: Primary API for subscription management
+
+#### Internal Controllers
+
+- **MultichainBalancesController**: Check user's crypto balances across chains
+- **TransactionController**: Create and manage crypto payment transactions
+- **ApprovalController**: Handle user approval for transactions
+- **NetworkController**: Get current network information
+- **AccountsController**: Access user account information
+- **UserStorageController**: Manage authentication tokens and user data
+
+### Messenger System Integration
+
+The Subscription Controller uses MetaMask's messenger system for inter-controller communication:
+
+```typescript
+type SubscriptionControllerMessenger = RestrictedMessenger<
+  'SubscriptionController',
+  | SubscriptionControllerActions
+  | MultichainBalancesControllerGetStateAction
+  | TransactionControllerGetStateAction
+  | ApprovalControllerGetStateAction
+  | NetworkControllerGetStateAction
+  | AccountsControllerGetStateAction
+  | UserStorageControllerGetStateAction,
+  | SubscriptionControllerEvents
+  | MultichainBalancesControllerAccountBalancesUpdatesEvent
+  | TransactionControllerTransactionStatusChangeEvent
+  | ApprovalControllerApprovalStateChangeEvent
+  | NetworkControllerStateChangeEvent
+  | AccountsControllerStateChangeEvent
+  | UserStorageControllerAuthTokenRefreshedEvent,
+  | 'SubscriptionController'
+  | 'MultichainBalancesController'
+  | 'TransactionController'
+  | 'ApprovalController'
+  | 'NetworkController'
+  | 'AccountsController'
+  | 'UserStorageController',
+  'SubscriptionController'
+>;
+```
+
+## Key Methods
+
+### Public API
+
+- `getSubscription()`: Retrieve current subscription status
+- `createSubscriptionViaCard()`: Initiate card-based subscription
+- `createSubscriptionViaCrypto()`: Initiate crypto-based subscription
+- `getAvailablePaymentOptions()`: Get user's available payment methods
+- `manageBilling()`: Access billing management portal
+- `cancelSubscription()`: Cancel active subscription
+
+### Internal Methods
+
+- `#checkExistingSubscription()`: Verify if user has active subscription
+- `#requestStripeCheckoutUrl()`: Get Stripe hosted checkout URL
+- `#checkCryptoBalance()`: Verify user's crypto balance for payment
+- `#createApprovalTransaction()`: Generate crypto payment transaction
+- `#monitorTransaction()`: Track transaction status
+- `#updateSubscriptionStatus()`: Update local subscription state
+- `#handleSubscriptionEvent()`: Process subscription change events
+- `#triggerAuthTokenRefresh()`: Trigger auth token refresh via user storage controller
+
+## Event Flow

+### Card Payment Flow
+
+1. User initiates card subscription
+2. Controller checks for existing subscription
+3. Controller requests Stripe checkout URL from subscription service
+4. Controller returns checkout URL to UI
+5. User completes payment on Stripe
+6. Subscription service notifies controller of success
+7. Controller updates subscription status and emits events
+
+### Crypto Payment Flow
+
+1. User initiates crypto subscription
+2. Controller checks for existing subscription
+3. Controller verifies user's crypto balance via MultichainBalancesController
+4. Controller creates approval transaction via TransactionController
+5. User approves transaction via ApprovalController
+6. Controller monitors transaction status
+7. On confirmation, controller updates subscription status and emits events
+
+### Subscription Event Handling
+
+1. Subscription service emits subscription change event
+2. Controller receives event and triggers auth token refresh via user storage controller
+3. Controller updates local subscription status
+4. Controller emits `subscriptionStatusChanged` event
+5. User storage controller handles auth token refresh and emits `authTokenRefreshed` event
+6. Other controllers can listen for auth token updates

Subject: [PATCH 0847/1148] fix: Keep delegated handlers when unregistering
 actions (#6395)

## Explanation

Keep delegated handlers around even when unregistering actions. This
helps with the resiliency of the messenger system in case actions are
unregistered and registered elsewhere in the chain of delegations. This
is also very useful for testing.

Additionally adjusts the error message thrown when a delegated action
handler cannot be found to match an undelegated one.

Subject: [PATCH 0848/1148] chore: Organize Messenger tests (#6418)

## Explanation

The Messenger tests for actions and events have each been moved into a
`describe` block. Additionally, test descriptions have been updated to
avoid starting with "should", in accordance with our test naming
conventions.

Subject: [PATCH 0849/1148] chore(network-controller): Speed up network client
 tests (#6377)

There are a large amount of tests that exist for the network client in
`network-controller`. This is because the network client assembles a
JsonRpcEngine middleware stack, one for Infura RPC endpoints and one for
custom RPC endpoints, and we must verify the resulting behavior across
not only official Ethereum RPC methods but also MetaMask-specific RPC
methods.

Unfortunately, running all of these tests takes a long time in
comparison to others, around 3.25 minutes. This is rather painful when
working with `network-controller`, as the feedback loop is quite long.
We can reduce this number by splitting up the suite of network client
tests into multiple files. This means that Jest is able to now run them
in parallel. As a result, they now run in about 1.5 minutes, a 2x
speedup.

Subject: [PATCH 0850/1148] Refactor: Eliminate duplicate code in
 AccountTrackerController (#6425)

## Explanation

### Problem
The `AccountTrackerController` contained a custom
`AccountTrackerRpcBalanceFetcher` class that duplicated functionality
already available in the existing `RpcBalanceFetcher` from
`rpc-balance-fetcher.ts`. This created unnecessary code duplication and
maintenance overhead.

### Solution
- **Removed** the redundant `AccountTrackerRpcBalanceFetcher` class
(lines 63-273)
- **Created** a helper function `createAccountTrackerRpcBalanceFetcher`
that configures the existing `RpcBalanceFetcher` to:
  - Fetch only native balances (ZERO_ADDRESS tokens)
- Optionally include staked balances when `includeStakedAssets` is
enabled
  - Filter out unwanted token balances using an empty tokens state
- **Updated** the constructor to use the new helper function instead of
the custom class

Subject: [PATCH 0854/1148] feat: Allow disabling namespace checks (#6420)

## Explanation

Messenger namespace checks can now be disabled by using the
`DISABLE_NAMESPACE` namespace constructor parameter, and setting the
`Namespace` type parameter to `string`. This makes it much easier to
mock messengers in unit tests.

Subject: [PATCH 0856/1148] test: Add additional tests for delegated action
 unregistration (#6419)

## Explanation

Add additional tests for what happens when you unregister an action
handler that has been delegated.

## References

This addresses a suggestion made on a previous PR:
https://github.com/MetaMask/core/pull/6395/files#r2303969488

## Checklist

Subject: [PATCH 0859/1148] fix(accounts-controller): workaround compiler error
 for recursive type (#6432)

## Explanation

Narrowing the `AccountControllerState` internally to avoid facing this
issue:
- https://github.com/MetaMask/utils/issues/168

This has no impact on the controller behavior or interface, it's purely
related to the type-system and compiler errors.

I had errors when I was running the test locally with the compiler, but
the CI ran fine. Now, it runs fine on both environment with no
error/warning.

Subject: [PATCH 0860/1148] fix: use signature as txhistory key for Solana
 bridge transactions (#6424)

## Explanation

This change fixes a bug in Solana post-submission logic in which the
txHistory key is set to a random uuid instead of the tx hash. This
causes txHistory lookups by txHash (for Solana transactions) to fail on
the clients

This is not a breaking change, but requires a migration on the clients
to set the txHistory key to the `historyItem.status?.srcChain?.txHash`
value for Solana transactions. This fixes txHistory items created prior
to this version of the bridge-status-controller

Migration script for extension:
https://github.com/MetaMask/metamask-extension/pull/35539/files#diff-3cd53aba68cf73714b1dbe70345a0b896589f13d8c3cc370d04393a5c6b4f0d8

This PR also fixes properties for the swap Completed events so that they
read data from the txHistory, if it exists

Subject: [PATCH 0862/1148] fix(account-tree-controller): emit
 `:selectedAccountGroupChange` during tree init (#6431)

## Explanation

The `init` function can be used in several scenarios:
- Initial controller initialization
  - Other controllers might want to know which group will be selected
- During re-onboarding, all accounts will be removed and the tree might
be re-`init`
- We want to fire the group that has been automatically selected after
resetting the entire tree

Subject: [PATCH 0864/1148] Release/528.0.0 (#6437)

Patch release for the `account-tree-controller` that fixes the initial
publish of `:selectedAccountGroupChange`.

There were no easy way to get the initial selected group (which is
mirrored for `AccountsController:getSelectedAccount`).

With this new fix, `init` will properly publish the event, allowing
other controllers to use the initial selected account group.

Subject: [PATCH 0865/1148] fix(account-tree-controller): remove account
 renamed handlers (#6438)

## Explanation

This PR removes `AccountsController:accountRenamed` handlers in
`AccountTreeController`.
This logic was mainly added to support legacy account syncing, but a
decision has been took to re-create the legacy syncing logic inside
`AccountTreeController` and apply it at the `AccountGroup` level, so
this won't be used anymore.

Subject: [PATCH 0868/1148] feat(keyring-controller): add new
 `KeyringController:addNewKeyring` action (#6439)

## Explanation

Adding new `:addNewKeyring` action so we can use it in the
`MultichainAccountService` when creating/importing new wallets.

This action could also be useful in other context, since it apply to all
keyring types we already support and not only HD keyrings.

Subject: [PATCH 0870/1148] feat: migrate eip-5792 & capabilities middleware
 handlers into monorepo (#6422)

## Explanation

We identified duplication in JSON RPC middleware logic between the
mobile and extension clients, particularly around the 5792 middleware
stack and capability handling. During recent Wallet API and Perps
integration discussions, the team agreed this presents an opportunity to
abstract and centralize this logic into a core monorepo module.

The motivation here is to:

* Reduce code duplication across mobile and extension clients
* Create a client-agnostic foundation for capabilities (including
auxiliary funds, capability advertising, and required assets)
* Support the upcoming Metamask Pay (MM Pay) initiative by establishing
a standardized middleware layer
* Facilitate future multi-chain and auxiliary funds work without
creating divergent patterns

So the work done on this PR aims to:

1. Create a new core package `eip-5792-middleware` to host shared
middleware logic.
2. Extract the 5792 middleware logic and capability handlers from both
extension and mobile clients.
a.
[Extension](https://github.com/MetaMask/metamask-extension/pull/35541)
   b. [Mobile](https://github.com/MetaMask/metamask-mobile/pull/19064)
4. Refactor them to be client-agnostic and consumable by both clients.
5. Maintain feature parity with existing implementations while improving
modularity and testability.
6. Include initial unit tests and integration hooks.

Subject: [PATCH 0871/1148] feat: BIP-44 support for EarnController (#6402)

## Explanation

To remove our dependency on AccountsController and use the new BIP-44
enabled AccountTreeController, this PR contains two main changes:

- Swaps out the listener `AccountsController:selectedAccountChange` for
`AccountTreeController:selectedAccountGroupChange`
- Swaps out the action `AccountsController:getSelectedAccount` for
`AccountTreeController:getAccountsFromSelectedAccountGroup` from which
we derive the EVM-compatible account

This relies on the latest 0.12.1 release of the account-tree-controller
package.

Small things of note:
- The account listener no longer needs the account payload to update the
account address as the race condition of concern [has been
fixed](https://github.com/MetaMask/core/pull/5555) (this is relevant to
mention still because despite using the new AccountTreeController event,
it still uses AccountsController under the hood)
- In the new `getSelectedEvmAccount()` function I initially handled the
case of no account being found (which shouldn't be possible) by failing
early with a 'No EVM-compatible account address found' error. But on
seeing how this case is handled by consuming functions (sometimes
returning early, sometimes returning empty objects, sometimes throwing
error) I opted to keep it consistent with the current code

## References

Fixes the core side of this issue:
https://consensyssoftware.atlassian.net/browse/TAT-1315?atlOrigin=eyJpIjoiMmQ2MDY1ZjQ4MDU5NDdiYmJhMjRhYzNiMThhMjEwYzIiLCJwIjoiaiJ9

And should be tested alongside the accompanying mobile repo update:
https://github.com/MetaMask/metamask-mobile/pull/19160

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

`@metamask/eip-5792-middleware` was incorrectly initialized with a
version of `1.0.0`. We need to initialize packages with a version of
0.0.0 before publication.

Reverts MetaMask/core#6446 because it was not published correctly due to
version being set incorrectly on a new package. This has since been
fixed, but we're reverting to re-attempt this publish.

Subject: [PATCH 0876/1148] feat: Add additional controller metadata (#6359)

## Explanation

Add the `includeInStateLogs` and `usedInUi` state metadata properties.
This is the implementation of the second option of this ADR:
https://github.com/MetaMask/decisions/pull/101

The `deriveStateFromMetadata` function has also been exported, rather
than adding two new exports for these new properties. The previous
exported state derivation functions (`getPersistedState` and
`getAnonymizedState`) have been deprecated in favour of
`deriveStateFromMetadata`.

## References

Related to https://github.com/MetaMask/decisions/pull/101

Fixes #6443

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0878/1148] Fix network-controller build (#6452)

In c4de052f66a53fee451e3e9ca3a648b0123d0be0, some of the
`network-controller` tests were reorganized. Unfortunately this causes
an issue when using the compiled version of the package in clients.
Having both a `create-network-client.ts` file and a
`create-nework-client/` directory (with no link between the two) seems
to confuse either `ts-bridge` or the TypeScript compiler, as it
generates a version of `create-auto-managed-network-client.ts` with an
invalid import path for `create-network-client.ts` (that is, it should
end with either `.cjs` or `.mjs` depending on the variant being
generated, but it does not). Renaming the `create-network-client/`
directory seems to fix the issue.

Reverts https://github.com/MetaMask/core/pull/6453 because it was not
published correctly due to release PR bumping the package to be released
but not the root monorepo version (in the root `package.json` file).

-->

Previously revoke token api will revoke and create new refresh token at
the same time.
This PR separate them into:
- `renewRefreshToken` method to renew refresh token from client
- `revokePendingRefreshTokens` method to revoke all pending old refresh
tokens instead from client

Subject: [PATCH 0883/1148] Integrate erc7715 types from
 @metamask/7715-permission-types package (#6379)

## Explanation

Integrate [ERC-7715](https://eip.tools/eip/7715) types from
[@metamask/7715-permission-types](https://github.com/MetaMask/delegation-toolkit/tree/main/packages/7715-permission-types)
package to avoid type duplication across multiple repos. MM clients will
use the ERC-7715 types exposed via the
`@metamask/gator-permissions-controller` to manage gator permissions.

## References

- Related to https://github.com/MetaMask/metamask-extension/pull/35219
- Requires: https://github.com/MetaMask/delegation-toolkit/pull/71

Subject: [PATCH 0886/1148] feat: add perps order notifications (#6464)

## Explanation

Adds perp order notification support.

This is technically already supported here, but moving to core will
reduce logic/complexity of setting up notifs.

Subject: [PATCH 0888/1148] fix(network-enablement-controller): enable Bitcoin
 networks if enabled in MultichainNetworkController (#6455)

## Explanation

Bitcoin networks are not enabled by default in the Network Enablement
Controller, causing the `enabledNetworks` object to show Bitcoin as an
empty namespace (`"bip122": {}`) instead of showing Bitcoin mainnet as
enabled. This is inconsistent with how Solana networks are handled. This
discrepancy is cashing a crash in Flask builds

This change makes Bitcoin networks follow the same enablement pattern as
Solana networks:

1. Default state: Bitcoin mainnet is now enabled by default in Flask
builds alongside Ethereum and Solana
2. Initialization: The `init()` method enables Bitcoin mainnet if it
exists in MultichainNetworkController configurations
3. Popular networks: The enableAllPopularNetworks() method now includes
Bitcoin mainnet enablement

## References

Fixes [#12345](https://github.com/MetaMask/metamask-mobile/issues/19201)

Subject: [PATCH 0890/1148] refactor!: Remove "data" event from
 SafeEventEmitterProvider (#6328)

## Explanation

The `SafeEventEmitterProvider` `'data'` event relies on the
`JsonRpcEngine` `'notification'` event, which per #6327 we are trying to
get rid of. After failing to find an instance outside of tests where we
actually use the `'data'` event, we assess that it can be removed.

## References

* Ref: #6327

+- **BREAKING:** Remove `'data'` event ([#6328](https://github.com/MetaMask/core/pull/6328))

Subject: [PATCH 0891/1148] feat: apply `mutex` on controller lock (#6292)

## Explanation

This PR adds `lock (mutex)` mechanism to the
seedless-onboarding-controller `setLocked` method to achieve the atomic
state updates and prevent unexpected issues (state out of sync) while
locking the controller and another operation (such as `changePassword`,
`addNewSecretData` etc) is in progress on the other hand.

As a result, we can't simply lock the seedless-onboarding-controller,
syncing with keyring's. Syncing with keyring's lock will cause more
issues in the controller communications as seedless-onboarding
`setLocked`, now, has some side effects and it won't get locked
immediately in some scenarios (when another seedless operation in
progress).
Hence, `setLocked` becomes independent of the Keyring's and this PR also
removes the `KeyringController:lock` and `KeyringController:unlock`
events from the seedless-onboarding messenger.

**BREAKING:**
- Removed `Keyring:lock` and `Keyring:unlock` events from the controller
allowed events.

Subject: [PATCH 0892/1148] feat(TokenBalanceController): Dynamic polling
 interval per chain (#6357)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

### Current State
The `TokenBalancesController` currently uses a single global polling
interval for all chains, with the implementation of *WebSocket-based
balance updates** we need **dynamic interval management** per chain (for
websocket-supported chains and for non-supported chains):

- **WebSocket-supported chains** should use minimal polling when
connected (WebSocket provides real-time updates)
- **WebSocket-disconnected chains** need frequent polling as fallback
- **WebSocket connection status changes dynamically**, requiring runtime
interval adjustments
- The current single-interval approach cannot adapt to changing
WebSocket connectivity states

### Solution
This PR introduces **dynamic per-chain polling intervals** that
integrate seamlessly with the **WebSocket service's connectivity
management**:

1. **Dynamic Interval Control**: WebSocket service can adjust polling
intervals in real-time via messenger actions based on connection status
2. **Connectivity-Aware Polling**: Connected chains use long intervals
(WebSocket handles updates), disconnected chains use short intervals
(polling fallback)
3. **Interval Grouping Strategy**: Chains with the same polling interval
are batched together, preserving AccountsAPI efficiency
4. **Messenger Integration**: `updateChainPollingConfigs` action enables
WebSocket service to control intervals dynamically

### ⚠️ **IMPORTANT: This is a Non-Breaking Change**
**All existing code continues to work exactly as it does today**:
- Existing `TokenBalancesController` instantiation without
`chainPollingIntervals` works unchanged
- Default polling behavior remains identical (single global interval)
- All existing APIs (`startPolling`, `stopPolling`, `updateBalances`,
etc.) work as before
- No changes required in MetaMask Extension or any consuming code

The new functionality is **purely additive** and **opt-in**.

### WebSocket Service Integration Flow
```typescript
// WebSocket service manages intervals based on connection status:

// When WebSocket connects, it calls:
this.controllerMessenger.call('TokenBalancesController:updateChainPollingConfigs', {
  '0x1': { interval: 300000 } // 5min - WebSocket handles real-time updates
});

// When WebSocket disconnects from a chain:
this.controllerMessenger.call('TokenBalancesController:updateChainPollingConfigs', {
  '0x1': { interval: 30000 } // 30s - fallback to frequent polling
});
```

### Technical Implementation
- **Real-time Adaptation**: WebSocket service dynamically adjusts
intervals based on connection health
- **Efficient Batching**: Chains are automatically regrouped by interval
when WebSocket service updates configs
- **Seamless Fallback**: Disconnected chains immediately switch to
frequent polling without manual intervention
- **Connection Recovery**: When WebSocket reconnects, polling
automatically reduces to backup frequency
- **Backward Compatibility**: All existing functionality preserved - new
features only activate when explicitly configured

### Example Runtime Behavior
```typescript
// Current behavior (unchanged):
new TokenBalancesController({ messenger, interval: 30000 })
// → All chains poll every 30s (exactly as today)

// New opt-in behavior:
new TokenBalancesController({
  messenger,
  interval: 30000, // Default fallback
  chainPollingIntervals: { '0x1': { interval: 300000 } } // Ethereum: 5min
})
// → Ethereum polls every 5min, other chains every 30s

- [x] I've updated the test suite for new or updated code as appropriate
- Added comprehensive test coverage for per-chain polling intervals and
dynamic updates
- Added tests for interval grouping, runtime configuration changes, and
batching behavior
  - **All existing tests continue to pass unchanged**
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
  - Added JSDoc comments for messenger actions and configuration options
- [x] I've communicated my changes to consumers by updating changelogs
for packages I've changed, highlighting breaking changes as necessary
- **Note**: **NO BREAKING CHANGES** - this is a purely additive
enhancement
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes
- **Note**: **NO BREAKING CHANGES** - existing code works unchanged,
WebSocket service integration uses new opt-in messenger actions

 ### Changed
 
+- Enhance `TokenBalancesController` with internal dynamic polling per chain support, enabling configurable polling intervals for different networks with automatic interval grouping for improved performance (transparent to existing API) ([#6357](https://github.com/MetaMask/core/pull/6357))
 - Bump `@metamask/base-controller` from `^8.2.0` to `^8.3.0` ([#6465](https://github.com/MetaMask/core/pull/6465))

Subject: [PATCH 0895/1148] feat: add account discovery to
 `MultichainAccountWallet` and providers (#6397)

## Explanation

### EvmAccountProvider
1. `discoverAndCreateAccounts` method added to perform discovery and
return the created account. The method will add an account to the
keyring and remove it (except for `groupIndex` 0) if it is found there
is no transaction history.
2. `getEvmProvider` method was added to grab the provider from the
`NetworkController`.

### SolAccountProvider
1. `discoverAndCreateAccounts` method added to perform discovery and
return the created account. This method does not create an account if
discovery yields no accounts.
2. Added a `#getKeyringClientFromSnapId` method that initializes the
keyring client into a newly added `#client` property.

### MultichainAccountWallet
1. `discoverAndCreateAccounts` method added to act as an orchestrator
for provider discovery. This method "fast-forwards" lagging providers to
the highest `groupIndex` being processed by a provider. At the end of
discovery, it will sync the wallet and then align all created groups.
The method returns only the discovered accounts (for consumption of the
clients' metrics).

Subject: [PATCH 0897/1148] feat: add multichain account group events (#6441)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

Add multichain account group lifecycle events to support the Back and
Sync feature (state 2). Events are emitted at the group level for
precise, targeted event emission without performance overhead.

**Current state**: MultichainAccountService creates and manages
multichain account groups but doesn't notify other controllers when
these operations occur.

**Solution**: Implemented two new events following the established
messenger pattern, with selective emission to prevent performance
degradation:
- `multichainAccountGroupCreated` - Emitted from wallet when new groups
are created via `createNextMultichainAccountGroup()` or
`createMultichainAccountGroup()`
- `multichainAccountGroupUpdated` - Emitted from group level when
specific groups are synchronized, ensuring only actually updated groups
trigger events

**Architecture**:
- Events are emitted at the appropriate granular level (group sync →
group events, group creation → wallet events)
- Initialization syncs don't emit events to prevent noise during startup
- Selective emission prevents performance degradation when only specific
groups/accounts are updated

Subject: [PATCH 0898/1148] feat(account-tree-controller): add account group
 name uniqueness validation (#6492)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
Currently there is no method for ensuring account group uniqeuness. This
PR adds function that does that.

- Implemented a new private method `#assertAccountGroupNameIsUnique` to
ensure account group names are unique across different groups.
- Updated `setAccountGroupName` to validate uniqueness before setting a
name.
- Added tests to verify that the same name can be set for the same group
and that duplicate names across different groups are prevented.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),

 ## [Unreleased]
 
+### Added
+
+- Add unique name validation for account groups to prevent duplicate group names ([#6492](https://github.com/MetaMask/core/pull/6492))
+  - `setAccountGroupName` now validates that group names are unique across all groups.
+  - Added `isAccountGroupNameUnique` utility function to check name uniqueness.
+  - Names are trimmed of leading/trailing whitespace before comparison to prevent accidental duplicates.
+
 ### Changed
 
 - **BREAKING:** Remove support for `AccountsController:accountRenamed` event handling ([#6438](https://github.com/MetaMask/core/pull/6438))

Subject: [PATCH 0900/1148] Reword circuit break error message (#6423)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The error that is thrown when an RPC endpoint responds with too many 5xx
errors in a row — causing the underlying circuit to break — is too
cryptic for end users. This commit rewords it to be more friendly and
recommend that users switch to another endpoint. It also logs the
original Cockatiel error so that users can inspect DevTools to learn
more.

- Old error: "Execution prevented because the circuit breaker is open"
- New error: "RPC endpoint returned too many errors, retrying in X
minutes. Consider using a different RPC endpoint."

 ## [Unreleased]
 
+### Added
+
+- Add `circuitBreakDuration` to the object returned by `createServicePolicy` ([#6423](https://github.com/MetaMask/core/pull/6423))
+  - This is the amount of time that the underlying circuit breaker policy will pause execution of the input function while the circuit is broken.
+- Add `getRemainingCircuitOpenDuration` to the object returned by `createServicePolicy` ([#6423](https://github.com/MetaMask/core/pull/6423))
+  - This returns the amount of time after which the underlying circuit breaker policy will resume execution of the input function after the circuit reopens.

Subject: [PATCH 0902/1148] refactor!: add messenger namespace to
 `AbstractMessageManager` (#6469)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
`AbstractMessageManager` currently uses `string` as namespace for all
derived messengers. This PR adds a `Name` generic type to
`AbstractMessageManager` to enforce type safety for messenger
namespaces.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

Subject: [PATCH 0903/1148] fix: prevent non-EVM account names from becoming
 group names (#6479)

## Explanation

[MUL-770](https://consensyssoftware.atlassian.net/browse/MUL-770)

**Problem:**
Account groups showed inconsistent names across app restarts due to a
bug introduced by https://github.com/MetaMask/core/pull/6246.

Users experienced:
- **First load**: "Solana Account 2"
- **After restart**: "Account 2"

**Root Cause:**
1. **ServiceStartTime Reset**: `serviceStartTime` changed on every app
restart, causing inconsistent `isNewAccount` detection
2. **Chain-specific Names in Groups**:
`EntropyRule.getComputedAccountGroupName()` returned individual account
names like "Solana Account 2" for multichain groups, which is
semantically incorrect since groups represent collections of accounts
across multiple chains

**Solution:**
Implemented the "quick fix" approach discussed Slack:
- **Only allow EVM account names** to bubble up to group names
- **Fallback to default naming** ("Account 1", "Account 2") when no EVM
accounts exist
- **Removed serviceStartTime logic** to ensure consistent behavior
across app restarts

## References

* Fixes the naming inconsistency bug reported by @danroc:
https://consensys.slack.com/archives/C080KDTTF6Y/p1756889328568689
* Regression introduced in https://github.com/MetaMask/core/pull/6246

Subject: [PATCH 0904/1148] feat: SubscriptionController: trigger token refresh
 (#6374)

## Explanation

Add a "triggerAuthTokenRefresh" method to the SubscriptionController,
which allows to trigger a refresh of the access token, for example,
after the subscription status has changed.

* If you had to upgrade a dependency, why did you do so?
-->
- Add `getCryptoApproveTransactionParams` which handle validating and
prepare params to create crypto approve transaction for user to sign
then submit to subscription service
- Add `startSubscriptionWithCrypto` which register submitted crypto
transaction with subscription service to start subscription

Subject: [PATCH 0907/1148] chore(profile-sync-controller): bring test grouping
 in line with other controllers (#6530)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR updates the `AuthenticationController` and
`UserStorageController` test suites to follow the same grouping and
structure used in other controller tests.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0908/1148] fix: allow disable last remaining network on
 namespace (#6499)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This change allows the last remaining network in a namespace to be
disabled. The reason is to align with BIP-44, where account groups
shouldn’t be forced to always keep at least one active network

Subject: [PATCH 0911/1148] feat: update nonce of existing transaction in batch
 (#6528)

## Explanation

When dynamically converting an existing transaction to a transaction
batch via the `batchTransactions` property, automatically update the
nonce and re-sign the existing transaction if it is not the first
transaction in the batch.

Subject: [PATCH 0912/1148] refactor: fully extract middleware into EIP-5792
 Middleware package (#6477)

## Explanation

The newly created EIP-5792 Middleware package ([PR
#6422](https://github.com/MetaMask/core/pull/6422)) currently contains
only the hooks required for the existing wallet middleware. To align
with the intended abstraction and reduce the monolithic nature of
wallet-middleware, we should fully extract the relevant middleware logic
from eth-json-rpc-middleware ([GitHub -
MetaMask/eth-json-rpc-middleware: Ethereum middleware for composing an
Ethereum provider using json-rpc-engine. Intended to replace
provider-engine](https://github.com/MetaMask/eth-json-rpc-middleware))
into this new package.

This PR moves the identified middleware into
@metamask/eip-5792-middleware.

Subject: [PATCH 0917/1148] chore: add BTC testnets to network enablement
 controller (#6474)

## Explanation

We need to add BTC testnets into the network enablement controller so
users can select testnets in Flask builds

## References

Related to https://github.com/MetaMask/metamask-mobile/issues/19201

## Checklist

 ### Changed
 
+- Add Bitcoin testnet and signet networks with default disabled state, with only mainnet enabled by default ([#6474](https://github.com/MetaMask/core/pull/6474))
 - **BREAKING:** Allow disabling the last remaining network in a namespace to align with BIP-44, where account groups shouldn't be forced to always keep at least one active network ([#6499](https://github.com/MetaMask/core/pull/6499))
 - Bump `@metamask/base-controller` from `^8.2.0` to `^8.3.0` ([#6465](https://github.com/MetaMask/core/pull/6465))

Subject: [PATCH 0918/1148] refactor: update account group name uniqueness
 checks (#6550)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?

This PR changes the account groupc uniqueness checks to validate
uniqueness only within the same wallet, allowing duplicates between
wallets.

+### Changed
+
+- Account group name uniqueness validation now scoped to wallet level instead of global ([#6550](https://github.com/MetaMask/core/pull/6550))
+  - `isAccountGroupNameUnique` now checks for duplicates only within the same wallet, allowing different wallets to have groups with the same name.
+  - Function now throws an error for non-existent group IDs instead of returning `true`.
+  - Updated `setAccountGroupName` behavior to allow duplicate names across different wallets.

Subject: [PATCH 0919/1148] feat: fetch balances accout api array (#6487)

## Explanation

Previously, the TokenBalancesController used a simple boolean
useAccountAPI configuration that applied an all-or-nothing approach -
either all chains would use the Accounts API for balance fetching, or
none would. This lacked the flexibility needed for real-world scenarios
where different chains have different levels of Accounts API support.

+- Add two new controller state metadata properties: `includeInStateLogs` and `usedInUi` ([#6473](https://github.com/MetaMask/core/pull/6473))
+
 ### Changed
 
 - **BREAKING:** `AbstractMessageManager` now expects a `Name extends string` generic parameter to define the name of the message manager ([#6469](https://github.com/MetaMask/core/pull/6469))

Subject: [PATCH 0926/1148] feat: add backup & sync capabilities to
 `AccountTreeController` (#6344)

## Explanation

This PR introduces comprehensive backup and synchronization capabilities
to `AccountTreeController`, adding account tree data persistence and
cross-device synchronization through user storage.

It adds one new public method to `AccountTreeController`,
`syncWithUserStorage`, that is intended to replace every current
occurence of `UserStorageController:syncInternalAccountsWithUserStorage`
in the clients.

Legacy account syncing is still performed as a migration to multichain
account syncing step, and is encompassed in this new
`syncWithUserStorage` public method.

The implementation features a new `BackupAndSyncService` with atomic
sync queues, bidirectional metadata synchronization, and rollback
mechanisms for failed operations.
The service automatically triggers sync operations when users add and
rename wallets/groups, change visibility states, or perform other
metadata modifications. Analytics tracking and performance tracing
provide observability into sync operations, while debug logging assists
with troubleshooting sync issues.

It is worth noting that this PR also removes all account syncing code
from `UserStorageController`.

 ### Added
 
+- **BREAKING:** Add backup and sync capabilities ([#6344](https://github.com/MetaMask/core/pull/6344))
+  - New `syncWithUserStorage()` and `syncWithUserStorageAtLeastOnce()` method for manual sync triggers, replacing `UserStorageController:syncInternalAccountsWithUserStorage` usage in clients.
+  - `BackupAndSyncService` with full and atomic sync operations for account tree data persistence.
+  - Bidirectional metadata synchronization for wallets and groups with user storage.
+  - Automatic sync triggers on metadata changes (rename, pin/hide operations).
+  - New `isBackupAndSyncInProgress` state property to track sync status.
+  - Analytics event tracking and performance tracing for sync operations.
+  - Rollback mechanism for failed sync operations with state snapshot/restore capabilities.
+  - Support for entropy-based wallets with multichain account syncing.
+  - Legacy account syncing compatibility for seamless migration.
+  - Optional configuration through new `AccountTreeControllerConfig.backupAndSync` options.
+  - Add `@metamask/superstruct` for data validation.
+- **BREAKING:** Add `@metamask/profile-sync-controller` and `@metamask/multichain-account-service` peer dependencies ([#6344](https://github.com/MetaMask/core/pull/6344))
 - Add two new controller state metadata properties: `includeInStateLogs` and `usedInUi` ([#6470](https://github.com/MetaMask/core/pull/6470))

Subject: [PATCH 0930/1148] feat: add feature announcement min version
 segmentation (#6554)

## Explanation

I may also add the versioning check logic into core too (however this
will be a fast follow)

Subject: [PATCH 0935/1148] feat(multichain-account-service): add
 `:walletStatusChange` event + mutex for concurrent mutable operations (#6527)

## Explanation

Wallet operations are not behind a mutex. This ensure that only one
mutable operation can be executed at a time.

Also publish new event, so we know in which state a wallet is.

> [!NOTE]
> A follow-up PR will be using those events to add a new status in the
`account-tree-controller`.

Depends on this PR to be merged first:
- [ ] https://github.com/MetaMask/core/pull/6560

 ### Added
 
+- Add mutable operation lock (per wallets) ([#6527](https://github.com/MetaMask/core/pull/6527))
+  - Operations such as discovery, alignment, group creation will now lock an internal mutex (per wallets).
+- Add wallet status tracking with `:walletStatusChange` event ([#6527](https://github.com/MetaMask/core/pull/6527))
+  - This can be used to track what's the current status of a wallet (e.g. which operation is currently running OR if the wallet is ready to run any new operations).
+- Add `MultichainAccountWalletStatus` enum ([#6527](https://github.com/MetaMask/core/pull/6527))
+  - Enumeration of all possible wallet statuses.
+- Add `MultichainAccountWallet.status` ([#6527](https://github.com/MetaMask/core/pull/6527))
+  - To get the current status of a multichain account wallet instance.
 - Add multichain account group lifecycle events ([#6441](https://github.com/MetaMask/core/pull/6441))
   - Add `multichainAccountGroupCreated` event emitted from wallet level when new groups are created.
   - Add `multichainAccountGroupUpdated` event emitted from wallet level when groups are synchronized.

Subject: [PATCH 0936/1148] fix(accounts-controller): fire `:accountAdded`
 before `:selectedAccountChange` on `KeyringController:stateChange` (#6567)

## Explanation

We were firing `:selectedAccountChange` before firing `:accountAdded`
which does have undesired side-effect in the `AccountTreeController`.

Mainly because the tree will try to get the associated selected account
group, but this account group does not exist yet (since it's using
`:accountAdded` to create the account groups).

This is more like a temporary solution, and `#update` could be slightly
refactored to a more robust solution later on.

Subject: [PATCH 0940/1148] feat(account-tree-controller): add `wallet.status`
 support (#6571)

## Explanation

We now listen to `:walletStatusChange` and update the tree accordingly.

This state can be used to track which operation is running on a given
wallet.

+- Add `AccountWalletObject.status` support ([#6571](https://github.com/MetaMask/core/pull/6571))
+  - The `status` field will now report the current wallet status.
+  - Uses `MultichainAccountService` to report on-going operations (discovery, alignment, account creations) for `AccountWalletEntropyObject` multichain account wallet objects.
+
 ### Changed
 
 - **BREAKING:** Bump peer dependency `@metamask/account-api` from `^0.9.0` to `^0.12.0` ([#6560](https://github.com/MetaMask/core/pull/6560))
+- Bump dependency `@metamask/multichain-account-service` `^0.7.0` to `^0.8.0` ([#6571](https://github.com/MetaMask/core/pull/6571))

Subject: [PATCH 0941/1148] fix(account-tree-controller): use
 multichain-account-service@0.8.0 (#6578)

## Explanation

The `account-tree-controller` now needs this new version for the
`:walletStatusChange` event, and I forgot update the peer dep
accordingly in the previous PR:
- https://github.com/MetaMask/core/pull/6571

Subject: [PATCH 0944/1148] feat(account-tree-controller): improve group
 creation events (#6582)

## Explanation

This PR improves how analytics events are sent when
`createMultichainAccountGroup` is called.
Prior to this PR, an event was sent even if the group already existed
locally. Now it is only sent if the group did not exist before.

Subject: [PATCH 0948/1148] Allow skipping lookupNetwork call in
 initializeProvider (#6575)

Currently, the extension patches `network-controller` so that
`initializeProvider` does not call `lookupNetwork`. Because
NetworkController gets initialized in the background process before the
UI process is initialized and because `lookupNetwork` makes a request to
the globally selected network, it was found that for a user installing
MetaMask and going through onboarding, we could share their IP address
with third parties before they had a chance to complete. That was
rightly flagged as a privacy violation, so the call to `lookupNetwork`
was disabled.

Now, long-term, `initializeProvider` shouldn't even exist (we can do
half of what it does in the constructor, and clients can already call
`lookupNetwork` separately). So at the moment the API for
NetworkController is not very ideal. However, we don't want to keep
having to patch `network-controller`.

For the time being, then, this commit adds a `lookupNetwork` option to
`initializeProvider`. This allows clients to disable the initial network
request more straightforwardly.

Subject: [PATCH 0952/1148] chore: remove legacy queueing integration params
 from SelectedNetworkController (#6430)

## Explanation

This PR is a re-do of https://github.com/MetaMask/core/pull/4941, which
got reverted in https://github.com/MetaMask/core/pull/5065.

It removes the togglability of per dapp selected network from the
SelectedNetworkController. [Full explanation in the original PR
here](https://github.com/MetaMask/core/pull/4941)

 ### Changed
 
+- The `SelectedNetworkController` constructor no longer expects a `useRequestPreference` boolean nor an `onPreferencesStateChange` listener. Removal of these parameters means that `domains` state will always be added for sites that are granted permissions. ([#6430](https://github.com/MetaMask/core/pull/6430))
 - Bump `@metamask/utils` from `^11.2.0` to `^11.4.2` ([#6054](https://github.com/MetaMask/core/pull/6054))
 - Bump `@metamask/base-controller` from `^8.0.1` to `^8.3.0` ([#6284](https://github.com/MetaMask/core/pull/6284), [#6355](https://github.com/MetaMask/core/pull/6355), [#6465](https://github.com/MetaMask/core/pull/6465))

Subject: [PATCH 0954/1148] fix: Strip `accessToken` from
 `AuthenticationController` state logs (#6553)

## Explanation

The metadata property was recently added to the
`AuthenticationController` in #6470, but we forgot to strip out the
`accessToken`. This is currently being stripped from state logs in both
clients.

The metadata was updated to strip out this token. Additionally, some
improvements were added to the metadata snapshot tests to ensure that
all properties are represented in the fixture state.

The `@metamask/utils` package was added as a dependency because the new
metadata state deriver uses `Json` in its signature, so that type is now
used in the exported types for this package.

## References

This is an amendment to #6470

Subject: [PATCH 0955/1148] fix: fix testnet cases (#6591)

## Explanation

Updates the NetworkEnablementController to disable networks across all
namespaces when enabling a network, rather than only disabling networks
within the same namespace. This change makes network selection truly
exclusive across all blockchain types (EVM, Bitcoin, Solana, etc.).

 ### Changed
 
 - Bump `@metamask/utils` from `^11.4.2` to `^11.8.0` ([#6588](https://github.com/MetaMask/core/pull/6588))
+- **BREAKING:** `enableNetwork()` and `enableAllPopularNetworks()` now disable networks across all namespaces instead of only within the same namespace, implementing truly exclusive network selection across all blockchain types ([#6591](https://github.com/MetaMask/core/pull/6591))

Subject: [PATCH 0956/1148] feat: Make breaking changes to next
 `base-controller` metadata (#6593)

## Explanation

Make the planned breaking changes to controller metadata. This includes
renaming `anonymous` to `includeInDebugSnapshot`, and it includes making
the two new metadata properties required.

## References

Relates to #6443

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0957/1148] Fix incorrect default Gator Permissions SnapId
 (#6546)

Fixes the default configuration for snapId, by adding the missing `npm:`
prefix

## Explanation

`GatorPermissionsController` provides a default value for
`permissionsProviderSnapId`, but previously this incorrectly omitted the
`npm:` prefix.

This change adds the prefix.

Changelog:
> Corrects the default Permissions Provider SnapId configuration value
for the `GatorPermissionsController` which was previously missing the
`npm:` prefix.

Subject: [PATCH 0963/1148] feat: reduce balance fetch calls for ws (#6600)

## Explanation

### Current State & Why Change is Needed
The current `AccountTrackerController` and `TokenBalancesController`
lack flexible control over which accounts to query during balance
updates. The system either queries all accounts or just the selected
account based on `isMultiAccountBalancesEnabled`, but there's no way to
explicitly control this behavior per operation. This limits the ability
to:
- Optimize performance by selectively querying accounts
- Provide granular control for different use cases
- Allow consumers to decide when to fetch all vs. selected account
balances

### Solution & How It Works
This PR **adds `queryAllAccounts` parameter support** to balance
fetching operations:

#### 1. Enhanced Method Signatures
- **`refresh(networkClientIds, queryAllAccounts?)`**: Now accepts
optional `queryAllAccounts` parameter
- **`updateBalances({ chainIds, queryAllAccounts })`**:
TokenBalancesController gains explicit control
- **`_executePoll({ networkClientIds, queryAllAccounts })`**: Polling
operations can specify account scope

#### 2. Flexible Account Selection Logic
- When `queryAllAccounts` is explicitly provided, it overrides the
default `isMultiAccountBalancesEnabled` behavior
- When not provided, falls back to existing
`isMultiAccountBalancesEnabled` preference
- Enables consumers to make contextual decisions about account querying
scope

#### 3. Improved Performance Control
- **Selective Updates**: Can choose to update only selected account when
full refresh isn't needed
- **Batch Operations**: Can explicitly request all accounts for
comprehensive updates
- **Context-Aware**: Different operations can use different strategies
based on their needs

#### 4. Backwards Compatibility
- `queryAllAccounts` parameter is optional in all methods
- Existing behavior preserved when parameter not provided
- No breaking changes to current API consumers

Subject: [PATCH 0964/1148] chore: add whitelist to utils to ignore warnings
 for specific networks (#6557)

## Explanation

Add a list of networks that will be treated as whitelisted not to
display the warning messages in the clients (Extension/Mobile) when
adding them as custom networks.
This list is starting with HyperEVM network.

## References

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),

Subject: [PATCH 0965/1148] feat: add enable network for namespace function
 (#6602)

## Explanation

**Current State:**
The NetworkEnablementController currently provides the `enableNetwork()`
method which implements cross-namespace exclusive behavior - when
enabling a network, it disables all other networks across all namespaces
(EVM, Solana, Bitcoin, etc.). While this ensures truly exclusive network
selection, there are use cases where users need to switch between
networks within a specific blockchain namespace without affecting
networks in other namespaces.

**The Solution:**
This PR adds a new `enableNetworkInNamespace()` method that provides
namespace-specific exclusive behavior. When called, it:

1. **Validates namespace consistency** - Ensures the provided chainId
belongs to the specified namespace, throwing an error if there's a
mismatch
2. **Enables namespace-specific exclusivity** - Disables all other
networks within the specified namespace only
3. **Preserves other namespaces** - Leaves networks in other namespaces
unchanged
4. **Creates namespace buckets** - Automatically creates the namespace
bucket if it doesn't exist

Subject: [PATCH 0966/1148] feat: Shared currency and token formatters (#6577)

## Explanation

This is a port of the new `Intl.NumberFormat` currency formatters from
metamask-extension. Moving it a shared library so it can be consumed
from both mobile and extension.

* What is the current state of things and why does it need to change?
There is inconsistent and multiple one-off implementations for fiat
currency and token formatting in the mobile and extension clients

* What is the solution your changes offer and how does it work?
Create a shared set of formatters that aligns mobile and extension.

Subject: [PATCH 0968/1148] chore: Synchronously initialise network controller
 provider if `lookupNetwork` is `false` (#6607)

## Explanation

This updates the `initializeProvider` function of the network controller
to be synchronous if `lookupNetwork` is `false`, i.e., when no async
operations need to be performed. Previously the function was `async`
meaning it would always return a promise, regardless of whether any
async operations are performed. With some function overloads and by
removing async (returning a promise instead when necessary), we can make
it fully synchronous when `lookupNetwork` is `false`.

Doing this will allow for safe initialisation of the network controller
state in places where awaiting may be difficult, like in the client's
modular controller initialisation.

Subject: [PATCH 0974/1148] feat: add timeout to evm discovery (#6609)

## Explanation

Previously, we didn't have a timeout/retry mechanism around provider
calls in the EVM provider. This can allow for a case where the provider
call hangs and holds up discovery. Two new helper methods were added to
ensure that we have timeout around the call and retries:
`#getTransactionCountWithRetry` and `#withTimeout`.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 0975/1148] Add metadata properties to `AnnouncementController`
 (#6524)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->
Adding new state metadata properties to `AnnouncementController`. This
controller has been migrated separately from the rest of Wallet UX
controllers, as the others are on the Extension client.

Subject: [PATCH 0977/1148] feat: add `Monad Mainnet` support to
 `@metamask/assets-controllers` (#6618)

## Explanation
This PR adds support for Monad Mainnet to the MetaMask assets
controllers by integrating the new blockchain network (chain ID 0x8f)
into the token detection and pricing systems.

### Notes
Monad Mainnet has not launch yet, there is no RPC but only infura to
support this network

Accounts API is not yet merged, so even we add the chain id, it wont
discover the balance via API, but the RPC

## Explanation

Reverting https://github.com/MetaMask/core/pull/6625 as the [Release
CI](https://github.com/MetaMask/core/actions/runs/17764289481/job/50484256349)
is failing.
The release was manually created and it looks like we messed something
up there.

(The reason for the manual work was that the controller was not showing
up when using `yarn create-release-branch -i`. Maybe because it's the
first release of the controller?)

Subject: [PATCH 0984/1148] Expose TransactionController methods needed by
 SmartTransactionsController through messenger (#6615)

Currently, the `confirmExternalTransaction`, `getNonceLock`,
`getTransactions`, and `updateTransaction` methods in
`TransactionController` are accessed by the
`SmartTransactionsController` constructor, but in a non-standard way:
`SmartTransactionsController` takes function references, when we would
like it to call these methods via the messenger instead.

This commit exposes these methods through TransactionController's
messenger so we can do this.

+### Added
+
+- Expose `confirmExternalTransaction`, `getNonceLock`, `getTransactions`, and `updateTransaction` actions through the messenger ([#6615](https://github.com/MetaMask/core/pull/6615))
+  - Like other action methods, they are callable as `TransactionController:*`
+  - Also add associated types:
+    - `TransactionControllerConfirmExternalTransactionAction`
+    - `TransactionControllerGetNonceLockAction`
+    - `TransactionControllerGetTransactionsAction`
+    - `TransactionControllerUpdateTransactionAction`
+
 ### Changed
 
 - Bump `@metamask/controller-utils` from `^11.12.0` to `^11.13.0` ([#6620](https://github.com/MetaMask/core/pull/6620))

Subject: [PATCH 0985/1148] fix(account-tree-controller): use
 `getSelectedMultichainAccount` (#6608)

## Explanation

Back-porting fix from:
- https://github.com/MetaMask/metamask-mobile/pull/19692

Basically, coming from our old account model, the selected account could
be a Solana account, thus, it might exactly match (speaking of group
index here) the equivalent EVM `getSelectedAccount`.

To fix this, we use `getSelectedMultichainAccount` which can either
select a EVM or non-EVM account, thus, allowing the controller to pick
the right account group.

 ### Changed
 
+- **BREAKING:** Use `:getSelectedMultichainAccount` instead of `:getSelectedAccount` to compute currently selected account group ([#6608](https://github.com/MetaMask/core/pull/6608))
+  - Coming from the old account model, a non-EVM account could have been selected and the lastly selected EVM account might not be using the same group index.
 - Bump `@metamask/utils` from `^11.4.2` to `^11.8.0` ([#6588](https://github.com/MetaMask/core/pull/6588))
 
+### Removed
+
+- Remove use of `:getSelectedAccount` action ([#6608](https://github.com/MetaMask/core/pull/6608))

Subject: [PATCH 0987/1148] feat: add `createMultichainAccountWallet` to
 `MultichainAccountService` (#6478)

## Explanation

### MultichainAccountService
1. `createMultichainAccountWallet` method that takes a mnemonic and
creates a new keyring from that mnemonic. It ultimately returns the
newly created wallet from that entropy source. This method should be
called from the clients, the wallet is intentionally empty and ripe for
calling of the `discoverAndCreateAccounts` method on it.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

 ## [Unreleased]
 
+### Added
+
+- Add `createMultichainAccountWallet` method to create a new multichain account wallet from a mnemonic ([#6478](https://github.com/MetaMask/core/pull/6478))
+  - An action handler was also registered for this method so that it can be called from the clients.
+- **BREAKING** Add additional allowed actions to the `MultichainAccountService` messenger
+  - `KeyringController:getKeyringsByType` and `KeyringController:addNewKeyring` actions were added.
+
 ### Changed
 
 - **BREAKING:** Rename `MultichainAccountWallet.alignGroup` to `alignAccountsOf` ([#6595](https://github.com/MetaMask/core/pull/6595))

Subject: [PATCH 0990/1148] feat: Add `Messenger` error reporting (#6605)

## Explanation

The `Messenger` class in `@metamask/messenger` has been updated to
accept an optional `captureException` constructor parameter. This is now
used to capture subscriber errors, instead of throwing them in a
`setTimeout` (which would cause a crash on mobile).

## References

This is the implementation of the 2nd option in this ADR:
https://github.com/MetaMask/decisions/blob/main/decisions/core/0016-core-classes-error-reporting.md#optional-captureexception-constructor-parameter-that-inherits-from-parent

Relates to #6613

 ## [Unreleased]
 
+### Added
+
+- Add `captureException` constructor parameter ([#6605](https://github.com/MetaMask/core/pull/6605))
+  - This function will be used to capture any errors thrown from subscribers.
+  - If this is unset but a parent is provided, `captureException` is inherited from the parent.
+
+### Changed
+
+- Stop re-throwing subscriber errors in a `setTimeout` ([#6605](https://github.com/MetaMask/core/pull/6605))
+  - Instead errors are captured with `captureException`, or logged to the console.

Subject: [PATCH 0991/1148] Add method to decode permission to
 GatorPermissionsController (#6556)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

- **Why change?**
When signing a permission, MetaMask must present the permission in a way
that is easily comprehensible to the user. Based on the design [shared
here](https://www.notion.so/metamask-consensys/SignTypedData-with-Metadata-Specification-22bf86d67d688023be67e2ee06e3a56a#22bf86d67d688023be67e2ee06e3a56a),
the permission must be decoded from the `eth_signTypedData_v4` request.

This PR adds that functionality to the `GatorPermissionsController`.

- **What’s the solution?**

Introduce `decodePermissionFromPermissionContextForOrigin` to
`GatorPermissionsController` and register a new action handler. It:
- Validates the caller origin matches `permissionsProviderSnapId`
(throws `OriginNotAllowedError` otherwise).
- Resolves enforcer contract addresses per chain via
`@metamask/delegation-deployments`. Throws if contracts are missing for
the chain.
- Identifies the permission type from caveats via
`identifyPermissionByEnforcers`, extracts expiry and permission-specific
data via `getPermissionDataAndExpiry`, and builds a `DecodedPermission`
via `reconstructDecodedPermission`.

- **Non-obvious pieces:**
- Added `@metamask/delegation-core` for terms helpers like
`createTimestampTerms` and `createNativeTokenStreamingTerms`, and
`ROOT_AUTHORITY`.
- Added `@metamask/delegation-deployments` to source enforcer addresses
and `CHAIN_ID`.
- Moved the decoding logic into a subfolder, to make it easier to export
internal functionality from `utils.ts` to facilitate low level unit
testing, without polluting the interface that is exposed to the
`GatorPermissionsController` with these functions.

Subject: [PATCH 0992/1148] feat: Add `BaseController` state derivation error
 reporting (#6606)

## Explanation

The state derivation functions exported by `@metamask/base-controller`
and `@metamask/base-controller/next` have been updated to accept a
`captureException` parameter. This is used to capture state derivation
errors, rather than throwing them in a `setTimeout` (which causes a
crash on mobile).

## References

This is the implementation of the 2nd option in this ADR:
https://github.com/MetaMask/decisions/blob/core-classes-error-reporting-strategy/decisions/core/0016-core-classes-error-reporting.md#optional-captureexception-constructor-parameter-that-inherits-from-parent

Fixes #6613

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

 ## [Unreleased]
 
+### Added
+
+- Add optional `captureException` parameter to `deriveStateFromMetadata`, `getPersistentState`, and `getAnonymizedState` ([#6606](https://github.com/MetaMask/core/pull/6606))
+  - This function will be used to capture any errors encountered during state derivation.
+
 ### Changed
 
 - Bump `@metamask/utils` from `^11.4.2` to `^11.8.0` ([#6588](https://github.com/MetaMask/core/pull/6588))
 - In experimental `next` export, rename `anonymous` metadata property to `includeInDebugSnapshot` ([#6593](https://github.com/MetaMask/core/pull/6593))
 - In experimental `next` export, make `includeInStateLogs` and `usedInUi` metadata properties required ([#6593](https://github.com/MetaMask/core/pull/6593))
 - In experimental `next` export, remove deprecated exports `getPersistentState` and `getAnonymizedState` ([#6611](https://github.com/MetaMask/core/pull/6611))
+- Stop re-throwing state derivation errors in a `setTimeout` ([#6606](https://github.com/MetaMask/core/pull/6606))
+  - Instead errors are captured with `captureException`, or logged to the console.

Subject: [PATCH 0995/1148] refactor(assets): use account-utils for wallet
 parsing (#6631)

## Explanation

This PR centralizes wallet parsing in assets controllers by using
`@metamask/account-utils` instead of bespoke parsing logic.

- Current state: parsing logic lived in assets controllers and
duplicated behavior covered by account-utils.
- Why change: reduce duplication, improve consistency, and rely on
shared utilities maintained by the account team.
- Solution: replace custom parsing with account-utils, adjust imports,
and make minimal logic-only edits; no behavioral changes intended.

Subject: [PATCH 0997/1148] Fix: TokenBalancesController selective session
 stopping to prevent polling interference (#6635)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

## 🐛 Problem

The `TokenBalancesController` had a critical issue where old polling
sessions would interfere with new ones when chain configurations
changed. This occurred because:

1. When `_startPolling` was called with new chain IDs, it would start
new custom interval timers
2. The base class would later call `_stopPollingByPollingTokenSetId` for
the old session
3. The custom `_stopPollingByPollingTokenSetId` implementation would
indiscriminately stop ALL polling, including the newly started sessions
4. This resulted in polling stopping unexpectedly when users switched
networks or when chain configurations were updated

## 🔧 Solution

Implemented **selective session stopping** in `TokenBalancesController`:

1. **Enhanced `_stopPollingByPollingTokenSetId`**: Now parses the
`tokenSetId` to extract chain IDs and only stops polling if they match
the currently active session
2. **Added session validation**: Compares incoming stop requests against
`#requestedChainIds` to prevent interference
3. **Graceful error handling**: Handles malformed `tokenSetId` by
falling back to stopping all polling
4. **Centralized timer management**: Introduced `#stopAllPolling()`
method for consistent cleanup

Subject: [PATCH 1003/1148] fix(account-tree-controller): remove full-sync
 triggers in single sync operations (#6634)

## Explanation

This PR removes full sync triggers when single sync operations are
enqueued and `hasSyncedAtLeastOnce` is `false`.
This prevents account syncing from running reactively on clients right
after vault creation but before onboarding is actually complete.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [x] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 1005/1148] feat: Shield: log transaction and signature (#6633)

## Explanation

Context: ShieldController

Once a transaction is submitted or a signature request is fulfilled, the
transaction hash or signature, respectively, are logged on the backend.

Subject: [PATCH 1006/1148] feat(multichain-account-service): add account
 providers config + add Solana discovery timeout (#6624)

## Explanation

Allow to pass some custom configurations to each built-in account
providers.

This should allow to easily customize them from the clients directly.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 1007/1148] fix(account-tree-controller): swallow group
 creation errors (#6642)

## Explanation

This PR swallows all group creation errors during backup and sync. This
was already the case for multichain syncs but we forgot to do it for
legacy syncs. It's now swallowed in every flow.

## References

Subject: [PATCH 1010/1148] feat: dynamic swap stablecoins and default slippage
 selector (#6616)

## Explanation

Adds a new selector `selectDefaultSlippagePercentage` that returns the
default slippage for a given chain and token combination
  - Returns `0.5` if requesting a bridge quote
  - Returns `undefined` (auto) if requesting a Solana swap
- Returns `0.5` if both tokens are stablecoins (based on dynamic
`stablecoins` list from LD chain config)
  - Returns `2` for all other EVM swaps

Clients can migrate existing slippage default logic and stablecoin
config to this selector. Example usage:

```
const getDefaultSlippage = createSelector(
  [
    (state) => state.metamask,
    (state) => getFromChain(state)?.chainId,
    (state) => getToChain(state)?.chainId,
    (state) => getFromToken(state)?.address,
    (state) => getToToken(state)?.address,
  ],
  (
    controllerStates,
    srcChainId,
    destChainId,
    srcTokenAddress,
    destTokenAddress,
  ) => {
    return selectDefaultSlippagePercentage(controllerStates, {
      srcChainId,
      destChainId,
      srcTokenAddress,
      destTokenAddress,
    });
  },
);
```

Subject: [PATCH 1012/1148] fix(multichain-account-service): prevent creating
 EVM account during discovery (#6650)

## Explanation

Derive next address instead of creating the account entirely (which
triggers `:accountAdded` and adds side-effects for this temporary
account).

+### Fixed
+
+- No longer create temporary EVM account during discovery ([#6650](https://github.com/MetaMask/core/pull/6650))
+  - We used to create the EVM account and remove it if there was no activity for that account. Now we're just deriving the next address directly, which avoids state mutation.
+  - This prevents `:accountAdded` event from being published, which also prevents account-tree and multichain-account service updates.
+  - Backup & sync will no longer synchronize this temporary account group, which was causing a bug that persisted it on the user profile and left it permanently.

Subject: [PATCH 1013/1148] feat(account-tree-controller): do not enqueue
 single syncs during full syncs (#6651)

## Explanation

This PR prevents single sync events from being enqueued if a full sync
is already in progress.
This prevents unnecessary client side network calls.

+- Single group sync events will not get enqueued anymore if a full sync is in progress ([#6651](https://github.com/MetaMask/core/pull/6651))

 support to `eip5792-middleware` (#6623)

## Explanation

This PR integrates the `auxiliaryFunds` and `requiredAssets`
capabilities defined under
[ERC-7682](https://eips.ethereum.org/EIPS/eip-7682) to enable auxiliary
funds flows and improve capability consistency across clients.

Subject: [PATCH 1016/1148] method
 'decodePermissionFromPermissionContextForOrigin' is now synchronous (#6656)

## Explanation

The method `decodePermissionFromPermissionContextForOrigin` was
incorrectly implemented as a synchronous function. This change updates
this function and related tests to be synchronous.

Because this function has not yet been released, this is not being
considered a breaking change.

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 1022/1148] fix(account-tree-controller): address group names
 consistency bug (#6601)

## Explanation

**CRITICAL FIX**: Resolves a severe multi-wallet account naming bug that
caused duplicate, inconsistent, and confusing account group names across
different seed phrases (SRPs).

### Current Problem
Users importing multiple seed phrases experienced catastrophic naming
issues:
- **Duplicate names**: Multiple "Account 2", "Account 3" within the same
wallet
- **Missing "Account 1"**: Some wallets would start at "Account 2"
- **Cross-wallet confusion**: Second SRP incorrectly showing "Account 3"
when it should be "Account 1"
- **Inconsistent after restart**: Names would change unpredictably on
app restart

### Root Cause
The account group naming logic had critical flaws:

1. **Broken alphabetical sorting**: Used
`Object.keys(wallet.groups).sort()` which caused conflicts and
duplicates in multi-wallet scenarios
2. **Unsafe entropy access**: Could throw TypeError when accessing
`group.metadata.entropy.groupIndex` without null checks
3. **Negative index bug**: Empty wallets would get `-1` index, causing
invalid "Account 0" names

### Solution
Implemented a robust fix with comprehensive improvements:

1. **Per-wallet sequential numbering**: Each wallet maintains
independent "Account 1", "Account 2", etc. numbering with dynamic
pattern detection that works with any naming convention ("Account N",
"Imported Account N", etc.)
2. **Smart conflict resolution**: Universal conflict detection with
`while` loop that finds next available unique name, handles user
renames, and ensures unique sequential names
3. **Entropy-aware indexing**: For multichain groups, prioritizes actual
`groupIndex` from entropy metadata when available with safe null checks
4. **Starting point optimization**: Begins name checking at
`wallet.groups.length` to minimize iterations and improve efficiency
5. **AutoHandleConflict integration**: Added optional
`autoHandleConflict` parameter to `setAccountGroupName()` for automated
conflict resolution with suffix generation (`"Account 1 (2)"`, `"Account
1 (3)"`, etc.) - ready for Backup & Sync integration

Subject: [PATCH 1029/1148] fix(account-tree-controller): do not save
 `lastUpdatedAt` for default names (#6672)

## Explanation

### Fixed

- Set `lastUpdatedAt` to `0` when generating default account group
names.
- This created conflicts with backup and sync, where newly created local
groups' names were taking precedence over user-defined backed up names.

Subject: [PATCH 1033/1148] fix: Ensure peer dependencies reflect latest
 breaking changes (#6652)

## Explanation

Our constraints for `peerDependencies` previously only required the
major version to match. However, this was problematic for pre-1.0
packages because it allowed for situations where we cannot update a
package without introducing a peer dependency error, since pre-1.0
packages can have breaking changes in minor or patch releases.

The constraint has been updated to require the most significant part of
the version to be synchronized for peer dependencies, and all resulting
constraint errors have been auto-fixed.

Subject: [PATCH 1035/1148] SWAPS-2839 update bridge controllers for bitcoin
 (#6454)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->


This PR extends the bridge controller to support Bitcoin transactions,
building on the existing Solana support to create a more generic non-EVM
chain handling system.

Current state: The bridge controller currently only supports EVM chains
and Solana for cross-chain transactions.

  Solution: This PR:
- Renames Solana-specific functions and types to be generic for all
non-EVM chains (NonEvmFees
  instead of SolanaFees, handleNonEvmTx instead of handleSolanaTx)
- Adds support for Bitcoin transactions using PSBT (Partially Signed
Bitcoin Transaction) format
- Updates the Snap interface to use the new unified computeFee and
signAndSendTransaction methods
  that work across all non-EVM chains
- Maintains backward compatibility while deprecating Solana-specific
naming

  Key changes:
- The nonEvmFeesInNative field now stores fees in the smallest units for
each chain
- Transaction handling now detects Bitcoin PSBT format alongside string
trade data

 ### Added
 
+- Add support for Bitcoin bridge transactions ([#6454](https://github.com/MetaMask/core/pull/6454))
+  - Handle Bitcoin PSBT (Partially Signed Bitcoin Transaction) format in trade data
+  - Support Bitcoin transaction submission through unified Snap interface
+  - Add Bitcoin-specific transaction handling in `#handleNonEvmTx` method
+  - Support extraction of `unsignedPsbtBase64` from trade data for Bitcoin transactions
 - Add new controller metadata properties to `BridgeStatusController` ([#6589](https://github.com/MetaMask/core/pull/6589))
 
 ### Changed
 
+- Update transaction submission to use new unified Snap interface for all non-EVM chains ([#6454](https://github.com/MetaMask/core/pull/6454))
+  - Replace `signAndSendTransactionWithoutConfirmation` with `ClientRequest:signAndSendTransaction` method
+  - Update response handling to support new `transactionId` format from unified interface
+  - Support multiple response formats: string, `{ transactionId }`, `{ result: { signature } }`, and `{ signature }`
+  - Maintain backward compatibility with legacy response formats
+- Rename transaction handling functions for clarity ([#6454](https://github.com/MetaMask/core/pull/6454))
+  - Rename `handleSolanaTxResponse` to `handleNonEvmTxResponse` to reflect support for all non-EVM chains
+  - Rename `#handleSolanaTx` to `#handleNonEvmTx` in BridgeStatusController
+  - Export `handleSolanaTxResponse` as an alias for backward compatibility (deprecated)
+- Update transaction detection logic to identify non-EVM transactions ([#6454](https://github.com/MetaMask/core/pull/6454))
+  - Check for Bitcoin PSBT format (`unsignedPsbtBase64` in trade object) alongside string trade data
+  - Use `isNonEvmChainId` for determining non-EVM transaction handling
+- Update chain ID handling for non-EVM chains ([#6454](https://github.com/MetaMask/core/pull/6454))
+  - Add fallback chain ID (`0x0`) when CAIP format can't be converted to hex for source chains
+  - Add fallback chain ID (`0x1`) for non-EVM destination chains
+- Update `getClientRequest` to create proper requests for all non-EVM chains ([#6454](https://github.com/MetaMask/core/pull/6454))
+  - Use `formatChainIdToCaip` to get proper scope for each chain
+  - Extract transaction data from either string or PSBT object format
+- Remove dependency on `@metamask/keyring-api` ([#6454](https://github.com/MetaMask/core/pull/6454))
 - Bump `@metamask/controller-utils` from `^11.12.0` to `^11.14.0` ([#6620](https://github.com/MetaMask/core/pull/6620), [#6629](https://github.com/MetaMask/core/pull/6629))
 - Bump `@metamask/base-controller` from `^8.3.0` to `^8.4.0` ([#6632](https://github.com/MetaMask/core/pull/6632))
 
+### Removed
+
+- Remove direct dependency on `@metamask/keyring-api` - no longer needed with unified Snap interface ([#6454](https://github.com/MetaMask/core/pull/6454))
+
 ## [43.0.0]

Subject: [PATCH 1037/1148] feat: Add bulk token scanning and introduce shared
 cache manager #6617 (#6483)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR extends the **PhishingController** to support bulk token
screening with caching, similar to the existing URL scanning
functionality. This PR also replaces the `urlScanCache` with a reusable
`cacheManager` class that is shared between both `urlScanCache` and now
`tokenScanCache`

**Changes introduced**
- Added a new `bulkScanTokens` method that can screen up to 100 tokens
per batch
- Implemented a new `cacheManager` class that handles caching logic with
a 15-minute TTL.
  - Replaced `urlScanCache` with `cacheManager`.
- Introduced `tokenScanCache` using the same `cacheManager` for
consistency and reuse.
- Defined cache key format as `${chainId}:${tokenAddress}` for token
scans.
- Registered `bulkScanTokens` as a controller action under
`PhishingControllerBulkScanTokensAction`.
- Exported new types for extension consumption and exposed the scanning
functionality via the messenger.

Screenshot showcasing the `tokenScanCache` is implemented as expected

This is grabbed via the extension console using await
stateHooks.getPersistedState() after triggering a swap in uniswap. You
will notice i was doing a swap for USDC which is the only token address
stored in the cache.

Subject: [PATCH 1038/1148] Release/573.0.0 (#6678)

## Explanation

Breaking changes for `sample-controllers`, `message-managers`, and
`eth-json-rpc-provider`, plus minor releases for any packages used by
that set of packages (to ensure nothing they rely on remains
unreleased).

## Explanation

Currently, PK/Hardware imports were being started at `Account 2` as
opposed to `Account 1`. When we apply group metadata we already have
that group in state, the logic in `#applyGroupMetadata` doesn't account
for the fact that the group we're applying metadata shouldn't be counted
for in the following line:
https://github.com/MetaMask/core/blob/main/packages/account-tree-controller/src/AccountTreeController.ts#L461.
Due to the way we apply group metadata (after we've added the groups
into state), we need to take the min between `proposedNameIndex` and
`highestAccountNameIndex` NOT the max. This change in logic accounts for
group metadata being applied in the scenario when the controller is
being rehydrated through `init` and when a new pk/hardware account is
added in an active session (and handled through `accountAdded`).

Subject: [PATCH 1042/1148] feat: decode permissions in SignatureController
 (#6619)

## Summary

Add execution-permission decoding to `SignatureController` for
`eth_signTypedData_v4` delegation requests. If a delegation request is
unable to be decoded into a coherent Execution Permission, reject
external (not from `origin: metamask`) attempts to sign delegations for
internal accounts. Adds decoded permission in signature request state
for rendering downstream.

## Why
Readable Permissions requires the ability to sign delegations, only when
the delegation can be decoded to a permission that is then shown to the
user.

[The architecture is described in this
document](https://www.notion.so/metamask-consensys/SignTypedData-with-Metadata-Specification-22bf86d67d688023be67e2ee06e3a56a).
Decoding has been added to `GatorPermissionsController` in #6556

Note: the request origin is always `@metamask/gator-permission-snap`
(any other origin is rejected). Because of this, `metadata` is added to
the 712 payload, defining the `justification` and `origin` which is the
_original_ origin of the request (the dapp).

-
-- Release/574.0.0 ([#6680](https://github.com/MetaMask/core/pull/6680))
-
-### Added
-
-- Add support for Bitcoin bridge transactions ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Handle Bitcoin PSBT (Partially Signed Bitcoin Transaction) format in trade data
-  - Add `BitcoinTradeDataSchema` and `BitcoinQuoteResponseSchema` validators
-  - Support Bitcoin chain ID (`ChainId.BTC = 20000000000001`) and CAIP format (`bip122:000000000019d6689c085ae165831e93`)
-- Export `isNonEvmChainId` utility function to check for non-EVM chains (Solana, Bitcoin) ([#6454](https://github.com/MetaMask/core/pull/6454))
-
-### Changed
-
-- **BREAKING:** Rename fee handling for non-EVM chains ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Replace `SolanaFees` type with `NonEvmFees` type
-  - Replace `solanaFeesInLamports` field with `nonEvmFeesInNative` field
-  - Update `#appendSolanaFees` to `#appendNonEvmFees` to support all non-EVM chains
-  - The `nonEvmFeesInNative` field stores fees in the smallest units for each chain (lamports for Solana, satoshis for Bitcoin)
-- Update Snap methods to use new unified interface for non-EVM chains ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Replace `getFeeForTransaction` with `computeFee` method that returns fees in native token units
-  - Update fee calculation to handle different unit conversions per chain
-  - Support fee computation for Bitcoin and Solana chains
-- Update quote validation to support Bitcoin-specific trade data format ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Add separate validation for Bitcoin quotes that include `unsignedPsbtBase64` field
-- Update selectors and utilities to use `isNonEvmChainId` instead of `isSolanaChainId` for generic non-EVM handling ([#6454](https://github.com/MetaMask/core/pull/6454))
-
-### Removed
-
-- **BREAKING:** Remove deprecated `SolanaFees` type - use `NonEvmFees` type instead ([#6454](https://github.com/MetaMask/core/pull/6454))

 ### Added
 
-- Add support for Bitcoin bridge transactions ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Handle Bitcoin PSBT (Partially Signed Bitcoin Transaction) format in trade data
-  - Support Bitcoin transaction submission through unified Snap interface
-  - Add Bitcoin-specific transaction handling in `#handleNonEvmTx` method
-  - Support extraction of `unsignedPsbtBase64` from trade data for Bitcoin transactions
 - Add new controller metadata properties to `BridgeStatusController` ([#6589](https://github.com/MetaMask/core/pull/6589))
 
 ### Changed
 
-- Update transaction submission to use new unified Snap interface for all non-EVM chains ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Replace `signAndSendTransactionWithoutConfirmation` with `ClientRequest:signAndSendTransaction` method
-  - Update response handling to support new `transactionId` format from unified interface
-  - Support multiple response formats: string, `{ transactionId }`, `{ result: { signature } }`, and `{ signature }`
-  - Maintain backward compatibility with legacy response formats
-- Rename transaction handling functions for clarity ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Rename `handleSolanaTxResponse` to `handleNonEvmTxResponse` to reflect support for all non-EVM chains
-  - Rename `#handleSolanaTx` to `#handleNonEvmTx` in BridgeStatusController
-  - Export `handleSolanaTxResponse` as an alias for backward compatibility (deprecated)
-- Update transaction detection logic to identify non-EVM transactions ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Check for Bitcoin PSBT format (`unsignedPsbtBase64` in trade object) alongside string trade data
-  - Use `isNonEvmChainId` for determining non-EVM transaction handling
-- Update chain ID handling for non-EVM chains ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Add fallback chain ID (`0x0`) when CAIP format can't be converted to hex for source chains
-  - Add fallback chain ID (`0x1`) for non-EVM destination chains
-- Update `getClientRequest` to create proper requests for all non-EVM chains ([#6454](https://github.com/MetaMask/core/pull/6454))
-  - Use `formatChainIdToCaip` to get proper scope for each chain
-  - Extract transaction data from either string or PSBT object format
-- Remove dependency on `@metamask/keyring-api` ([#6454](https://github.com/MetaMask/core/pull/6454))
 - Bump `@metamask/controller-utils` from `^11.12.0` to `^11.14.0` ([#6620](https://github.com/MetaMask/core/pull/6620), [#6629](https://github.com/MetaMask/core/pull/6629))
 - Bump `@metamask/base-controller` from `^8.3.0` to `^8.4.0` ([#6632](https://github.com/MetaMask/core/pull/6632))
 
-### Removed
-
-- Remove direct dependency on `@metamask/keyring-api` - no longer needed with unified Snap interface ([#6454](https://github.com/MetaMask/core/pull/6454))
-

 ## [Unreleased]
 
+### Changed
+
+- Add new group naming for non-HD keyring accounts ([#6679](https://github.com/MetaMask/core/pull/6679))
+  - Hardware-wallet account groups are now named: "Ledger|Trezor|QR|Lattice|OneKey Account N".
+  - Private key account groups are now named: "Imported Account N".
+  - Snap account groups are now named: "Snap Account N".
+- Account group names now use natural indexing as a fallback ([#6677](https://github.com/MetaMask/core/pull/6677)), ([#6679](https://github.com/MetaMask/core/pull/6679))
+  - If a user names his accounts without any indexes, we would just use the number of accounts to compute the next available index.
+
 ### Fixed
 
-- Fix group naming for PK/Hardware accounts ([#6677](https://github.com/MetaMask/core/pull/6677))
-  - Previously, the first PK/Hardware account would start as `Account 2` as opposed to `Account 1` and thus subsequent group names were off as well.
+- Fix group naming for non-HD keyring accounts ([#6677](https://github.com/MetaMask/core/pull/6677)), ([#6679](https://github.com/MetaMask/core/pull/6679))

Subject: [PATCH 1050/1148] fix: fix added popular network (#6693)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

**What is the current state of things and why does it need to change?**

The current `#onAddNetwork` behavior in `NetworkEnablementController`
was inconsistent and didn't provide a good user experience:
- All newly added networks were automatically enabled, regardless of
context
- The logic for determining "popular networks mode" required ALL popular
networks to be enabled, which was impractical
- Users experienced unexpected network switching when adding popular
networks in multi-network scenarios

**What is the solution your changes offer and how does it work?**

This PR implements a more intuitive network addition behavior:

1. **Improved Popular Networks Detection**: Changed from requiring "all
popular networks enabled" to ">2 popular networks enabled", making the
detection much more practical and user-friendly.

2. **Context-Aware Network Addition**:
- **If in popular networks mode (>2 popular networks enabled) AND adding
a popular network** → Keep current selection (add but don't enable the
new network)
- **Otherwise** → Switch to the newly added network (disable all others,
enable the new one)

3. **Key Benefits**:
- When users have multiple popular networks enabled and add another
popular network, their current workflow isn't disrupted
- When users add non-popular networks or add networks when not in
"popular mode", they get the expected behavior of switching to the new
network
- The popular networks threshold (>2) is much more realistic than
requiring all popular networks

**Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?**

- The method rename from `#areAllPopularNetworksEnabled()` to
`#isInPopularNetworksMode()` reflects the conceptual shift from checking
all networks to checking if the user is in a "popular networks" usage
pattern
- The ">2" threshold was chosen because it indicates the user is
actively using multiple popular networks (suggesting they prefer the
multi-network mode) vs. having just 1-2 networks enabled

## References

This change improves the user experience for network management in
MetaMask by implementing more intuitive network addition behavior based
on user context.

Subject: [PATCH 1055/1148] feat: allow partial revokes via
 `wallet_revokeSession` (#6668)

## Explanation

Uniswap reported a bug in slack
[here](https://consensys.slack.com/archives/C017NBJL1S7/p1758234734587359?thread_ts=1752698865.023109&cid=C017NBJL1S7)
where MetaMask was unpermitting any EVM connections for a dapp if that
dapp used the solana wallet standard provider to make a connect request
and then cancelled it.

This call to `disconnect()` is happening outside of our packages and is
not related to a previous but similar bug where our own wallet-standard
provider was calling `wallet_revokeSession` when receiving an empty
solana `accountsChanged` event.

To fix this, this PR proposes an implementation for partial permission
revoking in the `wallet_revokeSession` handler so that we can then
update our solana `wallet-standard` provider to only revoke the solana
scopes when it is asked to disconnect.

Subject: [PATCH 1057/1148] feat: remove `isMultichainOrigin` guard from
 `wallet_invokeMethod` handler (#6703)

## Explanation

Currently it is possible for the window.ethereum provider to grant
solana accounts and scopes in its permission requests. Whether or not
that should be allowed UX is up for debate. Regardless, it causes an
issue where if Solana accounts and scopes are granted AND a dapp also
uses our solana provider, the dapp will be unable to use the solana
provider to make requests without first re-requesting solana accounts
from the solana provider (not the EVM provider). This is because the
permission granted via window.ethereum has `isMultichainOrigin: false`
where as the solana provider's granted permissions go through the
multichain api which will have them set `true` which then gets caught in
this `isMultichainOrigin` guard in `wallet_invokeMethod` handler.

The original purpose of this guard was to make the multichain api
granted permissions equivalent to a window.ethereum set of permissions,
but not the other way around. Trying to encourage multichain api usage
over window.ethereum usage in this manner doesn't really make sense / is
not worth this hassle anymore.

Subject: [PATCH 1058/1148] feat(multichain-account-service): add timeout to
 Solana account creation (#6704)

## Explanation

Currently, we don't have an implicit SLA around Solana account creation,
so the account creation process can hang and generally degrade the UX.
I've added a new property to the `SolAccountProviderConfig`,
`createAccounts`, which has a `timeoutMs` property which can be used to
timeout Solana account creation. The default for the creation process is
3 seconds, but this can be configured on a per client basis.

Subject: [PATCH 1060/1148] fix(account-tree-controller): add account ordering
 logic with account groups (#6683)

## Explanation

It's been periodically observed that the accounts displayed in an
account group can be "out of order". This can result from two scenarios:

1. **Account Creation Race via `createNextMultichainAccountGroup`** -
Account creation takes longer than expected for a certain provider and
thus the faster provider gets to the account tree controller state first
which can lead to a scenario where e.g. you have Solana added before an
EVM account.
2. **Account Discovery** - Discovery for a certain provider might not
yield any results on a certain group index and an "out of order"
provider creates an account within the group first, with the "in order"
provider creating its account through the alignment process.

In order to always maintain order and avoid adding complicated logic
around trying to prevent a race condition or force account creation in a
certain order during discovery, I added the `sortOrder` property to an
account's context object. This `sortOrder` property is used in sorting a
group's accounts at the insertion level.

### Added

- Types: `AccountTypeKey`.
- Map: `ACCOUNT_TYPE_TO_SORT_ORDER`.
- Property: Added `sortOrder` to an account's context object to track
its sort order.

### Pros

1. No need for complicated logic where we try to control the account
creation process to eliminate out of ordered accounts in the above two
scenarios at the `MultichainAccountService` level.
2. The `MultichainAccountService` doesn't care about the order of
accounts and thus this should be dealt with at the
`AccountTreeController` level; the controller that is responsible for UI
state.
3. Easy to update the ordering we want to show in the UI through the
`ACCOUNT_TYPE_TO_SORT_ORDER` map.

### Cons

1. The changes will have a slight increase in memory footprint with a
new `sortOrder` property in an account's context mapping.
2. The `AccountTreeController` will have to re-calculate at every
insertion of an account, which is necessary considering an account can
be added in any order (cost is at best $O(n)$ and at worst $O(nlogn)$
where $n$ is the number of providers in a type of group).

Subject: [PATCH 1063/1148] fix: Fix `isFirstTimeInteraction` to be correctly
 settled when transferring ERCX tokens (#6686)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Currently we are deriving `isFirstTimeInteraction` property by asking
account - address relationship API with `txParams.to` as recipient. This
PR aims to fix the cases where recipient is in the data - for example
ERC20 / ERC721 / ERC1155 transfers.

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

For example:

* Fixes #12345
* Related to #67890
-->

* Fixes https://github.com/MetaMask/metamask-extension/issues/35595

Subject: [PATCH 1064/1148] fix(account-tree-controller): fix duplicate names
 for out-of-order accounts (#6706)

## Explanation

We were not re-using the persisted group name when checking for the next
available name during group metadata updates.

Meaning that if somehow, we were receiving a `:accountAdded` before
`init` was called, then the groups metadata would be empty, leading to
some duplicate names.

I spotted this issue with mobile E2E and our fixture system.

## References

E2E were failing on this PR, because of this bug:

Subject: [PATCH 1065/1148] feat(account-tree-controller): force-init before
 any account insertion/removal (#6709)

## Explanation

We now enforce that `init` got called before making any change to the
tree to avoid having out-of-order account groups.

I stumbled upon this bug when running E2E on mobile. Basically, the way
the fixture are setup on mobile were triggering `:accountAdded` before
calling `AccountTreeController.init`, which resulted in having "Account
2" inserted before "Account 1".

But, since "Account 1" was already part of the initial
`internalAccounts` it should have been inserted before any new accounts.

Thus, forcing `init` to be called implicitly fixes this order/sequence.

## References

E2E were failing on this PR, because of this bug:

 ## [Unreleased]
 
+### Added
+
+- Add `reinit` method ([#6709](https://github.com/MetaMask/core/pull/6709))
+  - This method can be used if we change the entire list of accounts of the `AccountsController` and want to re-initilize the tree with it.
+
+### Changed
+
+- Implicitly call `init` before mutating the tree ([#6709](https://github.com/MetaMask/core/pull/6709))
+  - This ensure the tree is always using existing accounts before inserting/removing any new accounts if `init` has not been called yet.
+
 ### Fixed
 
 - Fix use of unknown `group.metadata.name` when checking for group name uniqueness ([#6706](https://github.com/MetaMask/core/pull/6706))

Subject: [PATCH 1067/1148] feat: Integrate bulk token screening into
 transaction simulation flow within runAfterSimulateHook (#6617)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR integrates the bulk token screening functionality from the
`PhishingController` into the TransactionController's transaction
simulation workflow. When a transaction simulation completes with
received tokens, those tokens are scanned in a fire and forget method.

Changes introduced

- Added `#bulkScanReceivedTokens` method that scans tokens received
during transaction simulation
- Added `PhishingController:bulkScanTokens` to the
TransactionController's allowed actions
- Integrated token screening into the `#afterSimulate` workflow as a
fire and forget
- Filters received tokens from simulation data and passes them to
PhishingController for bulk screening

Screenshot showcasing the `tokenScanCache` is implemented as expected

This is grabbed via the extension console using await
stateHooks.getPersistedState() after triggering a swap in uniswap. You
will notice i was doing a swap for USDC which is the only token address
stored in the cache.

Subject: [PATCH 1069/1148] SWAPS-2839 bridge controller changes for bitcoin
 beta (#6705)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

This PR extends the bridge controller to support Bitcoin transactions,
building on the existing Solana support to create a more generic non-EVM
chain handling system.

Current state: The bridge controller currently only supports EVM chains
and Solana for cross-chain transactions.

Solution: This PR:

Renames Solana-specific functions and types to be generic for all
non-EVM chains (NonEvmFees
instead of SolanaFees, handleNonEvmTx instead of handleSolanaTx)
Adds support for Bitcoin transactions using PSBT (Partially Signed
Bitcoin Transaction) format
Updates the Snap interface to use the new unified computeFee and
signAndSendTransaction methods
that work across all non-EVM chains
Maintains backward compatibility while deprecating Solana-specific
naming
Key changes:

The nonEvmFeesInNative field now stores fees in the smallest units for
each chain
Transaction handling now detects Bitcoin PSBT format alongside string
trade data

 ## [Unreleased]
 
+### Added
+
+- Add support for Bitcoin bridge transactions ([#6705](https://github.com/MetaMask/core/pull/6705))
+  - Handle Bitcoin PSBT (Partially Signed Bitcoin Transaction) format in trade data
+  - Support Bitcoin chain ID (`ChainId.BTC = 20000000000001`) and CAIP format (`bip122:000000000019d6689c085ae165831e93`)
+- Export `isNonEvmChainId` utility function to check for non-EVM chains (Solana, Bitcoin) ([#6705](https://github.com/MetaMask/core/pull/6705))
+
+### Changed
+
+- **BREAKING:** Rename fee handling for non-EVM chains ([#6705](https://github.com/MetaMask/core/pull/6705))
+  - Replace `SolanaFees` type with `NonEvmFees` type (exported type)
+  - Replace `solanaFeesInLamports` property in quote responses with `nonEvmFeesInNative` property
+  - The `nonEvmFeesInNative` property stores fees in the native units for each chain (SOL for Solana, BTC for Bitcoin)
+- **BREAKING:** Update Snap methods to use new unified interface for non-EVM chains ([#6705](https://github.com/MetaMask/core/pull/6705))
+  - Snaps must now implement `computeFee` method instead of `getFeeForTransaction` for fee calculation
+  - The `computeFee` method returns fees in native token units rather than smallest units

 ## [Unreleased]
 
+### Added
+
+- Add support for Bitcoin bridge transactions ([#6705](https://github.com/MetaMask/core/pull/6705))
+  - Handle Bitcoin PSBT (Partially Signed Bitcoin Transaction) format in trade data
+  - Support Bitcoin transaction submission through unified Snap interface
+
+### Changed
+
+- **BREAKING:** Update transaction submission to use new unified Snap interface for all non-EVM chains ([#6705](https://github.com/MetaMask/core/pull/6705))
+  - Replace `signAndSendTransactionWithoutConfirmation` with `ClientRequest:signAndSendTransaction` method for Snap communication
+  - This changes the expected Snap interface but maintains backward compatibility through response handling
+- Export `handleSolanaTxResponse` as an alias for `handleNonEvmTxResponse` for backward compatibility (deprecated) ([#6705](https://github.com/MetaMask/core/pull/6705))
+- Rename `createClientTransactionRequest` from `signAndSendTransactionRequest` for clarity ([#6705](https://github.com/MetaMask/core/pull/6705))
+
+### Removed
+
+- Remove direct dependency on `@metamask/keyring-api` ([#6705](https://github.com/MetaMask/core/pull/6705))
+
+### Fixed
+
+- Fix invalid fallback chain ID for non-EVM chains in transaction metadata ([#6705](https://github.com/MetaMask/core/pull/6705))
+  - Changed from invalid `0x0` to `0x1` as temporary workaround for activity list display
+
 ## [45.0.0]

Subject: [PATCH 1072/1148] fix(account-tree-controller): prevent
 `:account{Added,Removed}` if `init` has not been called yet (#6717)

## Explanation

I initially thought calling `init` implicitly would solve some issues,
but it actually adds one when it comes to automatically migrating
accounts from v1 state.

In the clients we usually use the tree like so:
```ts
this.accountsController.updateAccounts();
this.accountTreeController.init();
```

The `updateAccounts` part re-creates the list of internal accounts and
potentially migrate them if needed (in the case of BIP-44, this is
needed to inject the `options.entropy` for those accounts).

If a `KeyingController:stateChange` happens before `updateAccounts`,
this might trigger some `:accountAdded` event, but some accounts might
not have been automatically migrated yet (since `updateAccounts` has not
been called at this point). Thus, this can lead the
`AccountTreeController` to misuse those accounts and put them in wrong
wallet (like older HD accounts had not `options.entropy` objects, thus
they are not considered BIP-44 accounts yet).

To avoid such issues (which seems to mainly happen for E2E), we wait for
`init` to have been called explicitly.

In anyway, calling `updateAccounts` right before `init` would make sure
that the list of accounts is up-to-date AND migrated.

When merging the patched changes from mobile, we missed changing the
default of `showMultiRpcModal` to `false`.

This is the link to the patch showing what the default is currently set
to.

https://github.com/MetaMask/metamask-mobile/blob/main/patches/%40metamask%2Bpreferences-controller%2B19.0.0.patch#L44

This PR corrects that.

Subject: [PATCH 1078/1148] chore(account-tree-controller): add logs (#6730)

## Explanation

Adding more debug logs to the service so we can diagnose potential
issues better (since it's not always easy to guess what happened only
with states)

Subject: [PATCH 1080/1148] fix(account-tree-controller): sort accounts by
 `importTime` to preserve groups order (#6727)

## Explanation

The `listMultichainAccounts` action has no guarantee about the accounts
ordering.

And when you combine this with `updateAccounts` that re-creates the list
of internal accounts based on each keyring states, we can have a
completely different ordering.

Usually `updateAccounts` goes from:
1. Primary HD keyring
2. Snap keyring
3. Other keyrings...

The problem with our new account models is that we're building the tree
from single accounts, so while the "Primary HD keyring" should be
re-built the same way everytime, other HD keyrings might not. Mainly
because the `listMultichainAccounts` will go through Snap accounts
(Solana here) before using the other HD keyrings.

And since Solana accounts can be easily "misaligned" (meaning their
associated account group could live before they are being created), this
can lead to some bad ordering when re-building up the group.

A concrete example would be:
- We import a 2nd SRP
- This creates the first EVM account everytime for this new wallet
  * But we don't necessarily creates its first Solana account right away
- We run account discovery on that SRP
  * Some accounts got found, let say until "group index 3"
    - This both created EVM and Solana accounts this time
- We run account alignment after the discovery to "re-align" all created
groups
  * This will create the missing (first) Solana account

Then, if you iterate over `listMultichainAccounts`, you would have
Solana accounts for that 2nd SRP coming first and then you would have
the (first) Solana account coming right after. This would create the
"Account group index 0" after the others...

 ### Fixed
 
+- Preverve import time for account groups ([#6727](https://github.com/MetaMask/core/pull/6727))
+  - We now wait sort accounts by their `importTime` before re-building the tree.
 - Prevent `:account{Added,Removed}` to be used if `init` has not been called yet ([#6717](https://github.com/MetaMask/core/pull/6717))
   - We now wait for `init` to have been called at least once. Clients will need to ensure internal accounts are fully ready before calling `init`.
   - This should also enforce account group ordering, since all accounts will be ready to consume right away.

Subject: [PATCH 1083/1148] fix: read selectedAccount from quote request and
 submitTx args (#6719)

## Explanation

This change replaces `getSelectedMultichainAccount` calls with
`getAccountByAddress(walletAddress)`, which mitigates tx submission
issues that happen when the selected account is different from the
account for which the quotes were fetched

Note that there are breaking changes (see changelogs) in the `submitTx`
and `updateBridgeQuoteParams` handlers.

 ### Changed
 
 - Bump `@metamask/utils` from `^11.8.0` to `^11.8.1` ([#6708](https://github.com/MetaMask/core/pull/6708))
+- **BREAKING** Add a required `accountAddress` parameter to the `submitTx` handler ([#6719](https://github.com/MetaMask/core/pull/6719))
+
+### Removed
+
+- Deprecate the unused `SnapConfirmationViewed` event ([#6719](https://github.com/MetaMask/core/pull/6719))
+
+### Fixed
+
+- Replace `AccountsController:getSelectedMultichainAccount` usages with AccountsController:getAccountByAddress` when reading account details required for submitting Solana transactions ([#6719](https://github.com/MetaMask/core/pull/6719))

Subject: [PATCH 1089/1148] fix: getCryptoApproveTransactionParams pricing from
 state (#6735)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Get pricing from state instead of fetching pricing from server in
`getCryptoApproveTransactionParams` since that method would be called
frequently by clients

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Use cached `state.pricing` in `getCryptoApproveTransactionParams`
(with new missing-pricing error) and add/register/export the
`getBillingPortalUrl` messaging action; update tests and changelog.
>
> - **SubscriptionController**:
> - Use `state.pricing` in `getCryptoApproveTransactionParams` instead
of fetching; throw `Subscription pricing not found` if absent.
> - Register new action handler
`SubscriptionController:getBillingPortalUrl`.
> - **Exports**:
> - Export `SubscriptionControllerGetBillingPortalUrlAction`,
`AllowedActions`, and `AllowedEvents` in `src/index.ts`.
> - **Tests**:
> - Update `getCryptoApproveTransactionParams` tests to seed
`state.pricing` and add case for missing pricing.
> - **Changelog**:
> - Note change to read pricing from state in
`getCryptoApproveTransactionParams`.

Subject: [PATCH 1090/1148] fix: improve balance fetch and not reset to 0
 (#6743)

## Explanation

### Current State and Problem
Previously, the `TokenBalancesController` would update token balances,
native balances, and staked balances regardless of whether the values
had actually changed. This led to several inefficiencies:

1. **Unnecessary state updates**: The controller would trigger state
changes even when balance values remained the same
2. **Performance overhead**: Unchanged balances would still go through
the entire update pipeline, causing unnecessary re-renders and
processing
3. **Reset behavior**: Balances could be reset to zero and then
immediately updated with the same value, creating unnecessary
intermediate states

### Solution
This PR implements value comparison logic to skip updates when balances
haven't actually changed:

1. **Token Balance Updates**: Added comparison between `currentBalance`
and `newBalance` before updating the state. Only updates are applied
when values differ, preventing unnecessary state mutations.

2. **Native Balance Updates**: Enhanced the filter logic to compare
existing balances from `AccountTrackerController` state with new balance
values. Only balances that have actually changed are included in the
update batch sent to `AccountTrackerController:updateNativeBalances`.

3. **Staked Balance Updates**: Similar optimization for staked balances,
comparing current staked balance values with new ones before including
them in the update batch sent to
`AccountTrackerController:updateStakedBalances`.

### Key Improvements
- **Reduced State Mutations**: Prevents unnecessary state updates when
balance values are identical
- **Better Performance**: Eliminates redundant processing and re-renders
caused by unchanged balance updates
- **Cleaner State Management**: Avoids intermediate states where
balances are reset to zero before being set to the same value
- **Batch Optimization**: Only sends actual changes to the
AccountTracker, reducing the payload size and processing overhead

### Technical Details
The implementation uses `isEqual` comparison for the main state update
check and direct value comparison (`currentBalance !== newBalance`) for
individual balance updates. This ensures that both the overall state
update and individual balance updates are optimized to only occur when
necessary.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Avoids unnecessary token/native/staked balance updates by comparing
existing values and only updating when changed, reducing state mutations
and calls.
>
> - **Fixed: Balance update churn**
>   - `TokenBalancesController`
> - Initialize missing entries without overwriting existing balances;
only set balances when values change.
> - Filter `updateNativeBalances`/`updateStakedBalances` calls by
diffing against `AccountTrackerController:getState` and only send
changed entries.
>     - Add `AccountTrackerController:getState` to allowed actions.
>   - `AccountTrackerController`
> - Optimize `updateNativeBalances` and `updateStakedBalances` to clone
state, compare current values, and call `update` only if changes exist.
> - **Tests**: Permit and stub `AccountTrackerController:getState`;
update messenger setups accordingly.
> - **Changelog**: Note fix for unnecessary balance updates to improve
performance.

Subject: [PATCH 1092/1148] feat(user-storage-controller): use deferred
 promises cache for KDF operations (#6736)

## Explanation

```md
- Use deferred promises for encryption/decryption KDF operations ([#6736](https://github.com/MetaMask/core/pull/6736))
  - That will prevent duplicate KDF operations from being computed if one with the same options is already in progress.
  - For operations that already completed, we use the already existing cache.
```

This improves startup performance on mobile by ~70%; going from an
average of ~6s to an average of ~2s for the time it takes to derive the
key.

## References

Fixes: https://consensyssoftware.atlassian.net/browse/MUL-1100

Subject: [PATCH 1094/1148] Release/589.0.0 (#6748)

## Explanation

Release for `@metamask/profile-sync-controller` &
`@metamask/multichain-account-service`.

```md
## [25.1.0]

### Changed

- Use deferred promises for encryption/decryption KDF operations ([#6736](https://github.com/MetaMask/core/pull/6736))
  - That will prevent duplicate KDF operations from being computed if one with the same options is already in progress.
  - For operations that already completed, we use the already existing cache.
- Bump `@metamask/utils` from `^11.8.0` to `^11.8.1` ([#6708](https://github.com/MetaMask/core/pull/6708))
- Bump `@metamask/keyring-api` from `^20.1.0` to `^21.0.0` ([#6560](https://github.com/MetaMask/core/pull/6560))
- Bump `@metamask/keyring-internal-api` from `^8.1.0` to `^9.0.0` ([#6560](https://github.com/MetaMask/core/pull/6560))
- Strip `srpSessionData.token.accessToken` from state logs ([#6553](https://github.com/MetaMask/core/pull/6553))
  - We haven't started using the `includeInStateLogs` metadata yet in clients, so this will have no functional impact. This change brings this metadata into alignment with the hard-coded state log generation performed by clients.today.
- Add dependency on `@metamask/utils` ([#6553](https://github.com/MetaMask/core/pull/6553))
- Bump `@metamask/base-controller` from `^8.3.0` to `^8.4.0` ([#6632](https://github.com/MetaMask/core/pull/6632))
```

Subject: [PATCH 1100/1148] fix: skip event publishing for txs submitted
 outside of the swap flow (#6739)

## Explanation

Propagates `featureId` into QuoteResponse objects and preserves its
value in txHistory. This prevents event publishing for transactions
submitted outside of the Unified Swap/Bridge experience (i.e., MM Pay).
See Bugbot note below for more details

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Skips publishing swap/bridge metrics for feature-tagged (e.g., PERPS)
txs, threads featureId from quote requests through fetch/results and
history, relaxes metadata typing, and updates tests accordingly.
>
> - **Bridge Status Controller**:
> - Skip tracking Submitted/Completed/Failed events when `featureId` is
present; always track `StatusValidationFailed`.
> - Store `featureId` in `txHistory` items; add perps-specific test
cases for confirmed/failed flows.
> - Make quote metadata handling more defensive (use optional
fields/Partial types) across submission, metrics, and USDT reset
helpers.
> - **Bridge Controller / Fetch**:
> - Add `featureId` param to `fetchBridgeQuotes` call path and append
`featureId` to each returned `QuoteResponse`.
> - Sort PERPS quotes by ETA when fetching; support LD overrides via
`featureId`.
> - **Types**:
> - Extend `QuoteResponse` with optional `featureId`; relax several
signatures to `Partial<QuoteMetadata>`.
> - **Tests**:
> - Update expectations to include `featureId`; add PERPS scenarios;
adjust snapshots and validation failure paths; minor param additions in
spies.

Subject: [PATCH 1101/1148] fix: token balance updates not respecting account
 selection (#6738)

## Explanation

This PR fixes the account processing logic in `TokenBalancesController`
to properly respect the `queryAllAccounts` parameter passed to the
`#updateBalances` method.

**Current state**: The controller was ignoring the `queryAllAccounts`
parameter passed to `#updateBalances` and always using the
instance-level `#queryAllAccounts` property instead. This meant that
callers couldn't override the default behavior on a per-call basis.

**Solution**: Enhanced the account processing logic to use the passed
`queryAllAccounts` parameter as a fallback to the instance property
using nullish coalescing (`??`). This allows:

- Method callers to explicitly override the default behavior by passing
`queryAllAccounts: true/false`
- The controller to fall back to its instance-level setting when no
parameter is provided
- Maintains backward compatibility while providing the expected
flexibility

**Technical details**: The change uses `(queryAllAccounts ??
this.#queryAllAccounts)` to properly handle the parameter precedence,
ensuring that when a caller explicitly passes `queryAllAccounts`, it
takes precedence over the instance setting.

Mobile PR: https://github.com/MetaMask/metamask-mobile/pull/20417

## References

This fix addresses an issue where the `queryAllAccounts` parameter in
the `#updateBalances` method was not being respected, limiting the
flexibility of balance update operations.

Subject: [PATCH 1104/1148] fix: await only EVM provider create accounts
 (#6755)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

This PR changes the way
`MultichainAccountWallet.createMultichainAccountGroup` works, by only
awaiting the EVM provider account creation, and moving the other
provider account creations to the background.
This will improve performance (measured as well as user felt) on
clients.

> [!NOTE]
> Only await EVM account creation in `createMultichainAccountGroup`;
start other providers in background with non-fatal errors, plus updated
logging/tests and changelog.
>
> - **MultichainAccountWallet**:
> - Await EVM provider `createAccounts` first; other providers run in
background and log warnings on failure.
> - Assert first provider is `EvmAccountProvider`; improved error
message includes provider name; remove `Promise.allSettled`/console.warn
path.
> - Minor import/typing refactors and use of
`ERROR_PREFIX`/`WARNING_PREFIX`.
> - **Tests**:
> - Update group-creation tests: failure only when EVM provider fails;
non-EVM failures don’t reject.
> - Ensure first mock provider is treated as EVM (prototype/index);
adjust helpers accordingly.
> - **Logger**: add `ERROR_PREFIX`.
> - **Changelog**: document new behavior (await EVM only, background
creation for others, brief misalignment possible).

 ## [Unreleased]
 
+### Changed
+
+- Only await for EVM account creation in `MultichainAccountWallet.createMultichainAccountGroup()` instead of all types of providers ([#6755](https://github.com/MetaMask/core/pull/6755))
+  - Other type of providers will create accounts in the background and won't throw errors in case they fail to do so.
+  - Multichain account groups will now be "misaligned" for a short period of time, until each of the other providers finish creating their accounts.

Subject: [PATCH 1106/1148] fix(account-tree-controller): re-use computed names
 for groups (#6758)

## Explanation

Re-enable computed names for account group names.

This allow to automatically migrate previous EVM names back to their
account group. This won't apply for newly added accounts though.

Once account groups are named at least once, they won't be renamed
again, so that should be enough to not rely on any migrations for this.

> [!NOTE]
> Re-enables computed account group names from legacy EVM account names
on first init, with fallback/default naming and conflict resolution;
updates tests and changelog.
>
> - **AccountTreeController**:
> - Re-introduces computed group names via
`#getComputedAccountGroupName`, using legacy EVM account names on first
init; ignores non-EVM names.
> - Refactors default naming into `#getDefaultAccountGroupName` and
updates `#applyAccountGroupMetadata` to accept `{ allowComputedName,
nextNaturalNameIndex }`.
> - During `init`, applies group metadata with `allowComputedName: true`
and natural indexing; retains uniqueness via `resolveNameConflict`.
> - **Tests**:
> - Adjust fixtures to empty per-account names; update expectations to
explicit default names (e.g., `Account 1`).
> - Add tests for computed names, non-EVM ignore, and automatic conflict
suffixing.
> - **Changelog**:
> - Notes re-introduction of computed names for account groups and
related behavior.

 ### Changed
 
+- Re-introduce computed names for account groups ([#6758](https://github.com/MetaMask/core/pull/6758))
+  - Those names are computed using the old internal account names, allowing to automatically migrate them.
+  - We only consider EVM account names.
+  - This automatically handles conflicting names, similarly to backup & sync (adding a suffix ` (n)` in case of conflicts.
 - Bump `@metamask/utils` from `^11.8.0` to `^11.8.1` ([#6708](https://github.com/MetaMask/core/pull/6708))

Subject: [PATCH 1108/1148] Fix CODEOWNERS to use new UX team identifiers
 (#6765)

Replace `@MetaMask/wallet-ux` with `@MetaMask/core-extension-ux` and
`@MetaMask/mobile-core-ux` so `CODEOWNERS` will validate successfully.

Subject: [PATCH 1111/1148] feat(multichain-account-service): add option to
 decide what to await for when creating group (#6759)

## Explanation

```md
- Add an optional `options` parameter to `MultichainAccountWallet.createMultichainAccountGroup()`
  - Introduces `options.waitForAllProvidersToFinishCreatingAccounts`, that will make `createMultichainAccountGroup` await either only the EVM provider or all the providers to have created their accounts depending on the value. Defaults to `false` (only awaits for EVM accounts creation by default).

Subject: [PATCH 1115/1148] feat: add feature announcement max version
 filtering (#6773)

## Explanation

Adds max version filtering for feature announcements. This will allow us
to show specific content below a version (e.g. prompt to update), and
new content for the newer versions.

> [!NOTE]
> Introduce maximum version fields and switch announcement filtering to
bounded (min/max) semver checks with comprehensive tests.
>
> - **Feature announcements filtering**:
> - Switch from minimum-only `gte` check to bounded checks using `gt`
(min) and `lt` (max) in `services/feature-announcements.ts`.
> - Always show when no `platformVersion`; hide on semver parse errors;
equality to bounds excluded.
> - **Data model**:
> - Add `extensionMaximumVersionNumber` and `mobileMaximumVersionNumber`
to `TypeFeatureAnnouncementFields` and include them in returned
notification `data`.
> - **Tests** (`services/feature-announcements.test.ts`):
> - Refactor to test both `minVersionField` and `maxVersionField` per
platform.
> - Add schemas covering min-only, max-only, combined bounds, undefined
versions, malformed versions, and no `platformVersion`.
> - **Changelog**:
> - Document addition of max bound version segmentation and new max
version fields.

There has been an advent of sites such as `sites.google.com` being used
maliciously that bypass the checks as they contain an allowlisted
hostname. This PR aims to enable the Phishing Controller to block URL
paths so that we can maintain the same allowlist but also block
malicious websites that use allowlisted hostnames.

> [!NOTE]
> Introduce path-based blocking to phishing detection using a PathTrie,
adding `blocklistPaths` and `whitelistPaths`, updating
controller/detector logic, API parsing, diffs handling, and tests.
>
> - **Phishing Controller**:
> - Add path-based blocking via `PathTrie` with new state fields
`blocklistPaths` and `whitelistPaths` in `PhishingControllerState` and
`PhishingListState`.
> - Update `test` and `bypass` to respect path whitelist and to add
matched blocking paths to `whitelistPaths`.
> - Parse stalelist from new API shape (`allowlist`, `blocklist`,
`blocklistPaths`, `fuzzylist`, etc.); convert `blocklistPaths` to trie
on load.
> - Extend `applyDiffs` to insert/delete path entries in
`blocklistPaths` using trie ops.
> - **Phishing Detector**:
> - Support `blocklistPaths` checks (hostname+path) and return matched
path; add `blockingPath(url)` helper.
> - **Utils**:
> - Add `PathTrie` module (`insertToTrie`, `deleteFromTrie`,
`matchedPathPrefix`, `convertListToTrie`, deep copy) and
`getHostnameAndPathComponents`, `getPathnameFromUrl` helpers.
> - **Tests/Docs**:
> - Add comprehensive tests for trie, detector/controller path behavior,
and utils; update changelog to note path-based blocking.

 ## [Unreleased]
 
+### Added
+
+- Add path-based blocking [#6416](https://github.com/MetaMask/core/pull/6416)
+  - Add `blocklistPaths` to `PhishingDetectorList`
+  - Add `blocklistPaths` to `PhishingDetectorConfiguration`
+  - Add `whitelistPaths` to `PhishingControllerState`
+  - Adds a type called PathTrie
+
 ### Fixed
 
 - Fixed phishing detector initialization failure when domain lists contain invalid values (numbers, null, undefined) by filtering them out ([#6767](https://github.com/MetaMask/core/pull/6767))

Subject: [PATCH 1119/1148] chore: Update `eth-json-rpc-middleware` (#6714)

## Explanation

Update `@metamask/eth-json-rpc-middleware` from v17 to v18. The breaking
changes relate to dropping support for the legacy middleware function
that pre-dates the creation of the RPC service, and some minor type
changes regarding that RPC service parameter.

Changelog:
https://github.com/MetaMask/eth-json-rpc-middleware/blob/main/CHANGELOG.md#1800

Subject: [PATCH 1120/1148] Fix: fix staked balances update (#6776)

## Explanation

### Current State & Problem
The `TokenBalancesController` had several issues that needed to be
addressed:

1. **Staked Balance Filtering Issue**: The controller was attempting to
fetch staked balances for all chains, including those that don't support
staking (like Polygon). This could lead to unnecessary network calls and
potential errors when trying to fetch staking data from chains that
don't have staking contracts.

2. **Static Chain Configuration**: The `accountsApiChainIds` parameter
was previously a static array (`ChainIdHex[]`), which made it difficult
to dynamically determine which chains should use the Accounts API
strategy at runtime.

### Solution
This PR implements three key improvements:

1. **Dynamic Chain Filtering for Staked Balances**:
- Added proper filtering to ensure staked balance updates only occur for
chains that actually support staking
- This prevents unnecessary API calls and potential errors for
unsupported chains like Polygon (0x89)

2. **Dynamic Chain ID Configuration**:
- **BREAKING CHANGE**: Changed `accountsApiChainIds` parameter from
`ChainIdHex[]` to `() => ChainIdHex[]` in both
`AccountTrackerController` and `TokenBalancesController`
- This enables dynamic configuration of chains that should use the
Accounts API strategy
- Allows runtime determination of supported chain IDs instead of
requiring a static array at initialization

### Implementation Details
- The staking balance filtering logic now checks against
`STAKING_CONTRACT_ADDRESS_BY_CHAINID` to only process chains that have
defined staking contracts
- The function-based `accountsApiChainIds` allows for dynamic
evaluation, enabling more flexible configuration based on runtime
conditions
- Comprehensive test coverage has been added to ensure the filtering
works correctly for both supported and unsupported chains

## References

* Fixes the staked balance update issue in TokenBalancesController

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate

- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Switch `accountsApiChainIds` to a function for dynamic Accounts API
chain support and filter staked balance updates by supported chains.
>
> - **Controllers**:
> - **API config (BREAKING)**: Change `accountsApiChainIds` from
`ChainIdHex[]` to `() => ChainIdHex[]` in `AccountTrackerController` and
`TokenBalancesController`; update internal usage
(`accountsApiChainIds()` in strategy setup and `supports`).
> - **Staked balances**: In `TokenBalancesController.updateBalances`,
filter staked balances by per-chain
`STAKING_CONTRACT_ADDRESS_BY_CHAINID` and update
`AccountTrackerController` via batched calls only when values change.
> - **Tests**: Update all tests to use function form of
`accountsApiChainIds` and cover API/RPC selection, error/timeout
handling, and staked-balance filtering by supported chains.
> - **Changelog**: Document breaking change and staked balance fix under
Unreleased.

@@ -11,6 +11,17 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 - add `platform` property to `TokenBalancesController` to send better analytics for which platform is hitting out APIs ([#6768](https://github.com/MetaMask/core/pull/6768))
 
+### Changed
+
+- **BREAKING:** Change `accountsApiChainIds` parameter from `ChainIdHex[]` to `() => ChainIdHex[]` in both `AccountTrackerController` and `TokenBalancesController` ([#6776](https://github.com/MetaMask/core/pull/6776))
+
+  - Enables dynamic configuration of chains that should use Accounts API strategy
+  - Allows runtime determination of supported chain IDs instead of static array
+
+### Fixed
+
+- Fix staked balance update on the `TokenBalancesController` , it's now filtered by supported chains ([#6776](https://github.com/MetaMask/core/pull/6776))
+
 ## [77.0.2]

Subject: [PATCH 1124/1148] chore: update wallet-integrations team code
 ownership (#6778)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Wallet API Platform team has recently merged with the SDK team to become
the Wallet Integrations team. This is simply updating the team name in
the `CODEOWNERS.md` file

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?
Are there client or consumer pull requests to adopt any breaking
changes?

Subject: [PATCH 1125/1148] chore: Add `name` and `state` properties to
 `ErrorReportingService` to support modular initialisation (#6781)

## Explanation

By adding a `name` and `state` (always `null`) property to a service, we
can make it work with modular initialisation in the clients.

Subject: [PATCH 1127/1148] chore:  BtcAccountProvider only creates native
 SegWit accounts (#6783)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Explanation

Update `BtcAccountProvider` to support only Native SegWit (`P2wpkh`)
accounts and removes Taproot handling. The account creation and
discovery will provision a `P2wpkh` account now.
This aligns the behavior with Solana/Tron providers.

> [!NOTE]
> Limit Bitcoin account creation/discovery to Native SegWit (P2wpkh) and
remove Taproot handling; update tests and changelog accordingly.
>
> - **Providers**:
>   - **`src/providers/BtcAccountProvider.ts`**:
> - `createAccounts` now creates only one `P2wpkh` account (removes
parallel `P2tr` creation).
> - `isAccountCompatible` restricted to `BtcAccountType.P2wpkh` (drops
`KeyringTypes.snap` check).
> - Discovery still calls `createAccounts`, thus provisioning only
`P2wpkh`.
> - **Tests**:
> - **`src/providers/BtcAccountProvider.test.ts`** updates expectations
to only handle `P2wpkh` accounts (lengths from 2→1, fixtures switched to
`MOCK_BTC_P2WPKH_ACCOUNT_1`).
> - **Changelog**:
> - Note that BTC provider now only creates/discovers Native SegWit
(`P2wpkh`) accounts.

Subject: [PATCH 1128/1148] initiate shield subscriptions polling (#6770)

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Implemented Polling mechanism for SubscriptionController.
This PR includes the following changes
- **BREAKING**: The `SubscriptionController` now extends
`StaticIntervalPollingController`, and the new polling API
`startPolling` must be used to initiate polling (`startPolling`,
`stopPollingByPollingToken`).
([#6770](https://github.com/MetaMask/core/pull/6770))
- **BREAKING**: The `SubscriptionController` now accepts an optional
`pollingInterval` property in the constructor argument, to enable the
configurable polling interval.
([#6770](https://github.com/MetaMask/core/pull/6770))
- Prevent unnecessary state updates to avoid emitting `:stateChange` in
`getSubscriptions` method.

> [!NOTE]
> Adds polling to `SubscriptionController` with configurable interval
and `getSubscriptionByProduct`, while optimizing state updates;
BREAKING: controller now extends polling controller and requires
`startPolling`.
>
> - **SubscriptionController**
> - **BREAKING**: Extends `StaticIntervalPollingController`; use
`startPolling`/`stopPollingByPollingToken` to manage polling.
> - Adds optional `pollingInterval` (defaults to
`DEFAULT_POLLING_INTERVAL`).
> - Implements `_executePoll` to fetch subscriptions and trigger
`triggerAccessTokenRefresh` on state changes.
> - Adds `getSubscriptionByProduct(product)` and corresponding action
export.
> - Optimizes `getSubscriptions` to avoid unnecessary state updates via
equality checks (subscriptions, trialed products, customerId).
> - **Dependencies/Config**
> - Adds `@metamask/polling-controller`; updates TS project references.
> - Test updates incl. polling behavior and order-insensitive state
checks; adds `sinon` for fake timers.
> - **Docs**
>   - Changelog updated with new method and breaking changes.

Subject: [PATCH 1132/1148] feat: shield: log not shown (#6667)

## Explanation

Adds the following feature to `shield-controller`:
When there is not coverage result for a transaction or signature,
`status: not_shown` is logged.

packages to resolve any breaking changes

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Logs status not_shown when no coverage result is available, switches
logging APIs to send full request context, and enforces coverageId
consistency.
>
> - **ShieldController**:
> - Logs signatures/transactions with `status` derived from coverage
presence (`shown` vs `not_shown`); no longer requires `coverageId` to
log.
> - Adds coverage ID consistency check; throws if latest `coverageId`
changes.
> - Refactors helpers: `#getCoverageStatus` introduced; minor internal
test helpers return updated entities.
> - **Backend**:
> - `logSignature`/`logTransaction` now accept `{ signatureRequest,
signature, status }` and `{ txMeta, transactionHash, status }`; request
bodies are constructed from these via new helpers.
> - Extracts `makeInitCoverageCheckBody` and
`makeInitSignatureCoverageCheckBody`; reuses them for init and log
endpoints.
> - **Types**:
> - Update `LogSignatureRequest` and `LogTransactionRequest` to use
`signatureRequest`/`txMeta` instead of `coverageId`.
> - **Tests**:
> - Updated to reflect new logging contracts and `not_shown` status;
added test for changed `coverageId` error.
> - **Changelog**:
>   - Notes logging `not_shown` when result is unavailable.
>

Subject: [PATCH 1133/1148] fix: fix check sum addresses on api fetcher (#6794)

## Explanation

**Current State & Problem:**
The `AccountsApiBalanceFetcher` was creating duplicate native token
entries in balance results - one with a checksummed address and another
with the original mixed/lowercase address from the API response. This
occurred because of inconsistent address casing handling when processing
balance data from the multi-chain accounts API.

**Root Cause:**
On line 299 in `api-balance-fetcher.ts`, the account address extracted
from the API response (`b.accountAddress?.split(':')[2]`) was not being
checksummed before use. This led to:

1. **Storage**: Mixed-case addresses were used as keys in the
`nativeBalancesFromAPI` Map (e.g., `0xabc123...`)
2. **Lookup**: Checksummed addresses from `addressChainMap` were used
for lookups (e.g., `0xAbC123...`)
3. **Result**: Key mismatch caused lookup failures, leading to duplicate
balance entries for the same native token

**Solution:**
The fix ensures consistent address formatting by applying the
`checksum()` function to the account address immediately after
extraction from the API response. This guarantees that:

- All addresses stored in `nativeBalancesFromAPI` are consistently
checksummed
- Subsequent lookups using checksummed addresses from `addressChainMap`
will find existing entries
- Eliminates duplicate native token balance entries

**Technical Details:**
The change is minimal but critical - replacing
`b.accountAddress?.split(':')[2] as ChecksumAddress` with
`checksum(b.accountAddress?.split(':')[2] || '')` ensures the extracted
address is properly checksummed before being used as a map key or in
balance processing logic.

## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate

Subject: [PATCH 1136/1148] Skip init if coverage id is available (#6792)

## Explanation

Currently the Shield Controller calls the `/init` endpoint every time a
coverage request is made.
This PR implements an optimization where the `/init` endpoint is skipped
if the coverage Id is already available.

> [!NOTE]
> Coverage checks now accept a request object with optional coverageId
to skip /init; controller, backend, types, tests, and changelog updated
accordingly.
>
> - **Breaking API**:
> - Update `ShieldBackend` to accept request objects: `checkCoverage({
txMeta, coverageId? })`, `checkSignatureCoverage({ signatureRequest,
coverageId? })` with new types `CheckCoverageRequest` and
`CheckSignatureCoverageRequest`.
>   - `CHANGELOG.md`: note breaking change for `checkCoverage`.
> - **Backend** (`src/backend.ts`):
> - `ShieldRemoteBackend` skips `v1/*/coverage/init` when `coverageId`
is provided; otherwise performs init then polls result.
> - **Controller** (`src/ShieldController.ts`):
> - Pass latest stored `coverageId` via `#getLatestCoverageId` to
`checkCoverage` and `checkSignatureCoverage` to enable init-skip.
> - **Tests/Utils**:
> - Update expectations to new call shape and add
`setupCoverageResultReceived` helper; adjust simulation flow and mocks
(e.g., `MOCK_COVERAGE_ID`).

Subject: [PATCH 1137/1148] feat(core-backend): add package (#6722)

Follow-up of https://github.com/MetaMask/core/pull/6490
PR focusing on merging the core-backend package first

## Explanation

### What is the current state, and why does it need to change?

Currently, MetaMask relies on polling-based HTTP requests to fetch
blockchain data like account balances and transaction updates. This
approach has several limitations:
- **Performance inefficiency**: Constant polling creates unnecessary
network requests and server load
- **User experience delays**: Users must wait for the next polling cycle
to see updates (typically 20 seconds to 10 minutes)
- **Resource consumption**: Mobile devices waste battery on frequent
HTTP requests
- **Scalability concerns**: As MetaMask grows, polling doesn't scale
well for real-time data needs

### What is the solution and how does it work?

This PR introduces the **`@metamask/core-backend`** package - a new data
layer platform that bridges backend services with MetaMask frontend
applications through efficient WebSocket-based real-time communication.

The solution provides:

1. **BackendWebSocketService**: Low-level WebSocket connection
management with automatic reconnection, authentication integration, and
intelligent message routing

2. **AccountActivityService**: High-level service for real-time account
activity monitoring

3. **Intelligent Fallback Strategy**: Dynamic coordination with existing
HTTP polling controllers - when WebSocket is connected, polling
intervals increase from 20s to 10 minutes; when disconnected, polling
returns to 20s with immediate balance fetches


### Key architectural benefits:

- **Real-time Performance**: Instant delivery of transaction and balance
updates via WebSocket push notifications
- **Resource Efficiency**: Reduces HTTP requests by 95% when WebSocket
is active (10min polling vs 20s polling)
- **Multi-chain Support**: CAIP-10 address format support for blockchain
interoperability
- **Mobile-Optimized**: Lifecycle-aware connection management for
background/foreground transitions
- **Extensible Design**: Platform foundation for future services (price
updates, etc.)

## Checklist

- [x] I've updated the test suite for new or updated code as appropriate
- High test coverage across BackendWebSocketService and
AccountActivityService
- Tests cover WebSocket lifecycle, reconnection scenarios, subscription
management, and integration patterns
  - Mobile-specific lifecycle testing included

- [x] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- 427-line comprehensive README with architecture diagrams, sequence
diagrams, and integration examples
  - Full JSDoc coverage for all public APIs
  - TypeDoc configuration for API documentation generation

- [x] I've communicated my changes to consumers by updating changelogs
for packages I've changed, highlighting breaking changes as necessary
  - CHANGELOG.md created following Keep a Changelog format
- Version 0.0.0 initial release - no breaking changes as this is a new
package

- [x] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes
  - No breaking changes - this is an additive new package
- Integration examples provided in README for Extension and Mobile
consumers
- Backward compatible - existing polling continues to work alongside
WebSocket enhancement

+## Installation
+
+```bash
+yarn add @metamask/core-backend
+```
+
+or
+
+```bash
+npm install @metamask/core-backend
+```
+
+## Quick Start
+
+### Basic Usage
+
+```typescript
+import {
+  BackendWebSocketService,
+  AccountActivityService,
+} from '@metamask/core-backend';
+
+// Initialize Backend WebSocket service
+const backendWebSocketService = new BackendWebSocketService({
+  messenger: backendWebSocketServiceMessenger,
+  url: 'wss://api.metamask.io/ws',
+  timeout: 15000,
+  requestTimeout: 20000,
+});
+
+// Initialize Account Activity service
+const accountActivityService = new AccountActivityService({
+  messenger: accountActivityMessenger,
+});
+
+// Connect and subscribe to account activity
+await backendWebSocketService.connect();
+await accountActivityService.subscribe({
+  address: 'eip155:0:0x742d35cc6634c0532925a3b8d40c4e0e2c6e4e6',
+});
+
+// Listen for real-time updates
+messenger.subscribe('AccountActivityService:transactionUpdated', (tx) => {
+  console.log('New transaction:', tx);
+});
+
+messenger.subscribe(
+  'AccountActivityService:balanceUpdated',
+  ({ address, updates }) => {
+    console.log(`Balance updated for ${address}:`, updates);
+  },
+);
+```
+
+### Integration with Controllers
+
+```typescript
+// Coordinate with TokenBalancesController for fallback polling
+messenger.subscribe(
+  'BackendWebSocketService:connectionStateChanged',
+  (info) => {
+    if (info.state === 'CONNECTED') {
+      // Reduce polling when WebSocket is active
+      messenger.call(
+        'TokenBalancesController:updateChainPollingConfigs',
+        { '0x1': { interval: 600000 } }, // 10 min backup polling
+        { immediateUpdate: false },
+      );
+    } else {
+      // Increase polling when WebSocket is down
+      const defaultInterval = messenger.call(
+        'TokenBalancesController:getDefaultPollingInterval',
+      );
+      messenger.call(
+        'TokenBalancesController:updateChainPollingConfigs',
+        { '0x1': { interval: defaultInterval } },
+        { immediateUpdate: true },
+      );
+    }
+  },
+);
+
+// Listen for account changes and manage subscriptions
+messenger.subscribe(
+  'AccountsController:selectedAccountChange',
+  async (selectedAccount) => {
+    if (selectedAccount) {
+      await accountActivityService.subscribe({
+        address: selectedAccount.address,
+      });
+    }
+  },
+);

+
+#### Key Flow Characteristics
+
+1. **Initial Setup**: BackendWebSocketService establishes connection, then AccountActivityService simultaneously notifies all chains are up AND subscribes to selected account, TokenBalancesController increases polling interval to 10 min, then makes initial HTTP request for current balance state
+2. **User Account Changes**: When users switch accounts, AccountActivityService unsubscribes from old account, TokenBalancesController makes HTTP calls to fill data gaps, then AccountActivityService subscribes to new account
+3. **Real-time Updates**: Backend pushes data through: Backend → BackendWebSocketService → AccountActivityService → TokenBalancesController (+ future TransactionController integration)
+4. **System Notifications**: Backend sends chain status updates (up/down) through WebSocket, AccountActivityService processes and forwards to TokenBalancesController which adjusts polling intervals and fetches balances immediately on chain down (chain down: 10min→20s + immediate fetch, chain up: 20s→10min)
+5. **Parallel Processing**: Transaction and balance updates processed simultaneously - AccountActivityService publishes both transactionUpdated (future) and balanceUpdated events in parallel
+6. **Dynamic Polling**: TokenBalancesController adjusts HTTP polling intervals based on WebSocket connection health (10 min when connected, 20s when disconnected)
+7. **Direct Balance Processing**: Real-time balance updates bypass HTTP polling and update TokenBalancesController state directly
+8. **Connection Resilience**: Automatic reconnection with resubscription to selected account
+9. **Ultra-Simple Error Handling**: Any error anywhere → force reconnection (no nested try-catch)

+
+/**
+ * High-performance service for real-time account activity monitoring using optimized
+ * WebSocket subscriptions with direct callback routing. Automatically subscribes to
+ * the currently selected account and switches subscriptions when the selected account changes.
+ * Receives transactions and balance updates using the comprehensive AccountActivityMessage format.
+ *
+ * Performance Features:
+ * - Direct callback routing (no EventEmitter overhead)
+ * - Minimal subscription tracking (no duplication with BackendWebSocketService)
+ * - Optimized cleanup for mobile environments
+ * - Single-account subscription (only selected account)
+ * - Comprehensive balance updates with transfer tracking
+ *
+ * Architecture:
+ * - Uses messenger pattern to communicate with BackendWebSocketService
+ * - AccountActivityService tracks channel-to-subscriptionId mappings via messenger calls
+ * - Automatically subscribes to selected account on initialization
+ * - Switches subscriptions when selected account changes
+ * - No direct dependency on BackendWebSocketService (uses messenger instead)
+ *
+ * @example
+ * ```typescript
+ * const service = new AccountActivityService({
+ *   messenger: activityMessenger,
+ * });
+ *
+ * // Service automatically subscribes to the currently selected account
+ * // When user switches accounts, service automatically resubscribes
+ *
+ * // All transactions and balance updates are received via optimized
+ * // WebSocket callbacks and processed with zero-allocation routing
+ * // Balance updates include comprehensive transfer details and post-transaction balances
+ * ```

Subject: [PATCH 1140/1148] Expose message and reason code (#6797)

## Explanation

The Shield backend returns `message` and `reasonCode` from the `/result`
endpoint, but we currently don't expose it.
This PR exposes these.

<!--

that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

## References

<!--
Are there any issues that this pull request is tied to?
Are there other links that reviewers should consult to understand these
changes better?

highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

Subject: [PATCH 1144/1148] chore: Add the optional "Client-Version" header in
 the Bridge Controller (#6791)

## Explanation
Adds the optional "Client-Version" header into API calls from the Bridge
Controller. E.g. `"Client-Version": "13.5.0"`

## References


## Checklist

- [ ] I've updated the test suite for new or updated code as appropriate
- [ ] I've updated documentation (JSDoc, Markdown, etc.) for new or
updated code as appropriate
- [ ] I've communicated my changes to consumers by [updating changelogs
for packages I've
changed](https://github.com/MetaMask/core/tree/main/docs/contributing.md#updating-changelogs),
highlighting breaking changes as necessary
- [ ] I've prepared draft pull requests for clients and consumer
packages to resolve any breaking changes

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Propagates optional client version through BridgeController and fetch
utils to send a Client-Version header on bridge/price API calls, with
tests and exports updated.
>
> - **Bridge Controller**:
> - Accepts optional `clientVersion` in constructor; stores and forwards
to `fetchBridgeQuotes` and `fetchAssetPrices`.
> - **Utils**:
> - Replace `getClientIdHeader` with `getClientHeaders` to include
`Client-Version` when provided.
> - `fetchBridgeTokens` and `fetchBridgeQuotes` accept/forward
`clientVersion` and send it in request headers.
> - `fetchAssetPrices`/internal price fetch use `Client-Version` header.
> - **Exports**:
>   - Export `getClientHeaders` from `index.ts`.
> - **Tests**:
> - Update tests to pass `clientVersion` and assert `Client-Version`
header; minor console spy restores.
> - **Changelog**:
> - Note addition of optional `Client-Version` header in API requests
under Unreleased.

## Explanation

<!--
Thanks for your contribution! Take a moment to answer these questions so
that reviewers have the information they need to properly understand
your changes:

* What is the current state of things and why does it need to change?
* What is the solution your changes offer and how does it work?
* Are there any changes whose purpose might not obvious to those
unfamiliar with the domain?
* If your primary goal was to update one package but you found you had
to update another one along the way, why did you do so?
* If you had to upgrade a dependency, why did you do so?
-->

Change field name so that we can easily use the new selector result
without doing a cumbersome mapping, as it currently clashes with a field
on an interface that uses the same name.

   - This controller manages the retrieval and caching of remote feature flags. It fetches feature flags from a remote API, caches them, and provides methods to access and manage these flags. The controller ensures that feature flags are refreshed based on a specified interval and handles cases where the controller is disabled or the network is unavailable.
