+SMOLDOT is not exactly a substrate client. It is mainly designed to work with Polkadot. But with

+This has to do with the fact that consensus and a few other bits of the client and runtime are not
+100% independent. For example, GRANDPA has a pallet on the runtime side, but is mostly in the

-
-- Emphasize more: SMALDOT is not the _substrate client itself compiled to Wasm_, it is another
-  codebase, which can do most of the things that substrate client can do.
-
-- Wasm runtime can allocate memory, it just does't have an allocator itself out of the box.
