Here's a diagram I made for NIP-46 signing flow with Frostr... - nostr client sends nip46 request to relay - igloo server listens for nip46 request - approves - passes to other signer (igloo-cli) for partial sig - gets response from cli and completes sig - passes back to relay - nostr client receives signed note and publishes to relays All of thise happens within like 2 seconds wtf

Key rotation is done manually still - you need the threshold of shares within that keyset (2/3 for example) locally in order to recover the nsec, this does not happen over nostr in some fancy protocol manner (only signing does) shares are only valid within a keyset meaning that if you have a 2/3 and you lose a share IF you destroy the other 2 shares than the third stolen share is ORPHANED. So to rotate at this time the steps are: - Recover nsec with threshold of shares - Use that nsec to generate a new keyset (can be any threshold) - DESTROY the shares in the old keyset TLDR; DESTROY AND OPRHAN View quoted note →

Here is our demo from Bitcoin 2025 this might help! View quoted note →

Split your nsec into a multisig The keys of that multisig talk to each other over nostr to sign notes View quoted note →

Also yes, frostr uses frostr for nostr. We eating our dogfood now! View quoted note →

Hello world! Frostr is a fully open-source protocol + app suite that lets you: • Split your existing Nostr key into any threshold (2/3, 3/5, etc)
 • Sign notes using simple Frostr apps that coordinate over Nostr
 • Use NIP-07 + NIP-46 in any Nostr client
 • Recover your nsec on any device with your threshold
 • Rotate / expand your setup anytime
 • And do it all without creating a new key
 We’ve got some cool updates shipping soon! Keep an eye out
