AI UTXO management. Connect to your bot and manage your labels. Currently leaks a lot of data and only testing this on signet, but in a future with a local specialized LLM, this can be done privately and for free.

If you're hanging out on github starring stuff go ahead and star this too!

Privacy-first Bitcoin signer with complete UTXO control - satsigner/satsigner

A wallet should work with all hardware, and vice versa.

Nostr enabled interoperability Inspired by @Andreas Griffin and @Bitcoin Safe NIP-17 messages for label sync and group chat. Coming soon to multisig PSBT signer.

Too specific is useless Too broad is meaningless Do anything As long as it’s in sats

Multisig is hard? Picture this: You're a dad who has set up an education fund for your son. You establish a 3-of-5 multisig wallet where you hold 2 keys, your son's mother holds 2 other keys, and your son holds the fifth key. You keep one of your keys in a hot wallet to cover ongoing expenses, while the other key is hidden away in case you need to sign twice. Your wife has the same setup, and your son has his key in a hot wallet. You, your wife, and your son can sign transactions using your hot wallets if there are no issues. However, if you or your wife have a disagreement or are incapacitated, your son will need to convince both of you to sign twice. You coordinate all of this via a NIP-17 Nostr group chat directly on the wallet. The group is derived from the wallet descriptor following the protocol developed by @Andreas Griffin for @Bitcoin Safe , ensuring interoperability. The focus is on providing a frictionless user experience for multisig transactions. #bitcoinuxui #uxui
