Bitcoin Taproot Multisig Signing

Passport Core
1

Hi,
I want to sign a taproot multisig transaction where the taproot can be described with miniscript.
The internal key is an unspendable key: 50929b74c1a04954b78b4b6035e97a5e078a5a0f28ec96d547bfee9ace803ac0

  1. Is it possible to sign these kind of transactions with Passport Core?
  2. Can this feature be added?
  3. Are there any guidelines to update the firmware with a fork of the open source code?

Hi @ekrembal,

  1. Passport does not yet support taproot multisig or miniscript
  2. We plan to add Miniscript later this year.
  3. You’ll need to build and sign the firmware yourself, then upload your pubkey to the device. More info here.
