use Flexible Round Optimized Schnorr Threshold (FROST) signatures to create a joint nostr account with your friends.

FROST is a threshold multisignature (t-of-n), so to make a post/event you require t parties to individually sign and contribute signature shares. These signature shares are then combined into a single schnorr signature which is valid under the joint public key.

Extremely unsafe and violently untested

Please do not add this to any nostr client list.

git clone https://github.com/nickfarrow/frostr

then cargo run or

cargo install --path .
frostr

Choose menu options 0-1, copy-paste and share things between participants. Take care to only share "secrets" with the intended recipient!

FROST Paper

Docs for our implementation & some important notes

• Sign a valid nostr event using FROST
• Refactor requests for input, buffers, and whitespace
• Proper CLI
• Colorful terminal
• Allow users to sign more arbitrary events (e.g. change profile)
• Allow users to sign non-nostr related messages
• Remove unwraps everywhere
• Show list of available frost keys
