HW multisig message signing #524

Open mandelbit opened 2 years ago

mandelbit commented 2 years ago

Am I correct in stating there is currently no standard for signing messages with multisig HW cosigners?

It'd be nice if HWI supported this feature.

Correct, there is no standard for signing messages with a multisig. There is, in general, no standard for signing messages with anything other than a p2pkh address. BIP 322 aims to solve that, but it seems like progress has stalled on it.
