What is the best method to verify the multisig addresses on all devices that are part of the set up?
When I signed a tx with cold card, it became aware of the other XPUB and I was able to export the addresses to a file and compare them to what sparrow was showing.
Is the same possible with nostr:npub17tyke9lkgxd98ruyeul6wt3pj3s9uxzgp9hxu5tsenjmweue6sqq4y3mgl
?
Yes, definitely supported. Best practice is to print one or more copies of the wallet descriptor at the time of initial wallet creation, so you have durable documentation instead of having to trust the coordinator later on. Change address verification is part of our standard transaction workflow, or you can also scan change/receive addresses to initiate a verification routine. You can also browse change/receive addresses in index-order within the UI. The key part is to have the descriptor as a QR code so you can scan it into the signer.
The seed signer device/project is good for bitcoin. Thank You. 🙏
Check out this tool. It's in Beta. It lets you challenge your key holders by getting them to sign a message. They need the private key but they don't need the multisig xpub.
From the GitHub: "Confirm that cosigners to multisignature bitcoin wallets can sign using signatures. Do they have a key that works?"
