Testnet4 demo on Trustchain Mobile app

App Download

Install from Google Drive (account trustchain.devs@gmail.com) by scanning this QR code (requires enabling "Install unknown apps" on the Android device):

Trustchain Mobile configuration

After installing the app and following the initial onboarding process, go to Settings and set these fields:

• Trustchain endpoint (this must be set first!): https://trustchain.ddns.net
• Root event date: 27 January 2026, with confirmation code: 6c8

Demo

Scan the first three QR codes above to demonstrate issuance & verification of credentials. With a second device running the same app, these credentials can be presented, scanned and verified (in the case of the driving license, with redactable fields).

Scan the last two QR codes (safeparking.co.ok & safe-parking.co.ok) to demonstrate URL verification as defence against QR code scams.

See the docs for the demo storyboard.
