PSBT [BIP174] based signing interface

Open thomaseizinger opened this issue 5 years ago • 1 comments

Currently, signing a transaction involves a stateful protocol in which bits and pieces of the transactions need to be sent over.

Are there any plans of creating an interface that accepts a PSBT and does all the signing in one go?

As per the spec (https://github.com/bitcoin/bips/blob/master/bip-0174.mediawiki#Signer) no additional data sources should be required if the PSBT is constructed correctly.

HWI (https://github.com/bitcoin-core/HWI) should be the reference to do that and compare against
