Question: Does signPsbt API support for signing a taproot P2TR multi-sig transaction?

[mint-pz]

Xverse wallet does support it following their example: secretkeylabs/xverse-core#388 (comment)

But when I tried the same code with Unisat wallet, I got the error finalize/taproot: unknown input. So, I'd to know if the Unisat wallet supports for signing a taproot P2TR multi-sig transaction via signPsbt method?

My bad, I am able to sign with Unisat but got error when broadcasting

I found that, I used account #.1 #.2 #.3 to sign, but the tx included the pubkey of #.4, not #.2

Please check your code carefully to ensure you didn't make anything wrong. Then try again. If your issue persisted, please upload the related code for check. @mint-pz

Thanks for your response, @cloud6605. I'll check it later. But I'd like to know if Unisat theoretically supports this type of signing like Xverse did?

We support sign multiple transactions at once. You may use signPsbts function.
