And for those of you still allowed on the bird app, here's the announcement post over there: https://twitter.com/unchainedcap/status/1636395076866781184
We've been working on a lot of important things at Unchained but it's been a while since we've been able to give open source as much resources as we would have liked. Really excited and proud of the set of features we're announcing this week supporting Ledger 2.0 wallet policy registration.
This is not just about new features for Unchained clients, but also for the ecosystem. Caravan now has the ability to persist Ledger policy registrations, which is an improvement for security and usability. Ledger users can now verify addresses on their device. Any other coordinators that support the config file serialization can also use the registrations.
We also released the first (to our knowledge) PSBTv2 tooling in JavaScript as part of this as Ledger 2.0 only accepts the newer encoding.
And our HWI-like library for interfacing with signing devices has drop-in backwards and forwards compatible support for all new Ledger interactions: registrations, address verification, and signing with registrations.
