So fired up to announce another major open-source contribution from the Unchained engineers. We've helped make the world's most popular hardware wallet a 1st class citizen for multisig

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.
