📝 Original message:Note that a number of wallet companies are now supporting the UR encoded
version of PSBTs, allowing for better QR & Airgap solutions, and also
leverage CBOR which is an IETF standard.
We have a community of Airgap wallet developers at
https://github.com/BlockchainCommons/Airgapped-Wallet-Community
…and libraries at
https://github.com/BlockchainCommons/crypto-commons#urs
We’d love for you to register UR as well, maybe as bitcoin/psbt+ur
Can you bring this up in our community for further discussion?

Thanks!
