NIP-46: Nostr Connect

NIP-46 defines remote signing, allowing a signer application to hold keys while clients request signatures over Nostr relays.

How It Works

1. Signer generates a connection URI (bunker:// or nostrconnect://)
2. User pastes the URI into a client
3. Client sends signing requests as encrypted events to the signer’s relay
4. Signer prompts user for approval, returns signed events

Connection Methods

• bunker:// - Signer-initiated connection
• nostrconnect:// - Client-initiated connection via QR code or deep link

Supported Operations

• sign_event - Sign an arbitrary event
• get_public_key - Retrieve the signer’s public key
• nip04_encrypt/decrypt - NIP-04 encryption operations
• nip44_encrypt/decrypt - NIP-44 encryption operations
