Collaboration in a Multisig
Collaborative signing of a 2-of-3 Multisig wallet using Bitcoin Safe ā across different computers, hardware wallets, and secure communication via Nostr.
This video shows how two users collaboratively sign a Bitcoin transaction using a 2-of-3 multisig wallet setup in Bitcoin Safe. Each participant is on a different computer, using different hardware wallets (Jade and Bitbox02). They coordinate through the appās built-in Chat & Sync feature, which uses Nostr to relay messages privately and securely.
The process supports both synchronous and asynchronous signing ā perfect for users who arenāt online at the same time.
