Remote Signing (NIP-46)

Remote signing keeps your private keys on a separate device — like your phone running Amber. The browser extension never sees your keys.

How it works

1. Your signer app (e.g., Amber) holds your private key
2. Buho Jump sends signing requests over Nostr relays
3. Your signer app approves and returns the signed event
4. The website gets the result — your keys never touched the browser

Setting up

QR Code method

1. Choose Connect Remote Signer during account setup
2. Select QR Code
3. A QR code appears — scan it with your signer app
4. Approve the connection on your phone

Bunker URI method

1. Copy the Bunker URI from your signer app (bunker://...)
2. Choose Connect Remote Signer during account setup
3. Paste the URI
4. The connection is established

Limitations

Remote signer accounts have one limitation: they cannot use NIP-17 encrypted messaging (which requires direct key access for gift-wrap encryption). Chat falls back to NIP-04 messaging, which still works but uses an older encryption standard.

Everything else works the same — signing events, permissions, wallet connections, and website interactions.
