Description

I was surprised to see this when testing out the BCUR2 additions, but it looks like we don't have address verification for coldcards. probably want to add this.

It would require:

  • Enabling it in this dropdown
  • Including a step/button to register if not done already
  • added to the test suite

Until we have proper message signing interactions, this can be done by just giving instructions for the address explorer (after registration)

Contributor guide

Research direction
Examine existing address verification for other hardware wallets, understand Coldcard's address explorer API, and implement the UI dropdown and test suite accordingly.
