cool! Joinstr wallet library in Rust. I'm excited with Nostr as a protocol for wallets to communicate and Bull Bitcoin is happy to support projects that leverage nostr for this purpose.

Bull Bitcoin has also been working (stealth) on our own protocol for wallets to communicate over Nostr for another purpose which doesn't have anything to do with collaborative transactions... I think it will be a huge breakthrough in Bitcoin wallet user experience. coming soon... but yes the Bull Bitcoin will have a Nostr component soon (but it won't be for social media, since that area is already well covered by Primal Damus etc.)
