nostr-connect-demo

Demo app pair for Nostr Connect NIP-46, including a client with UI.

Warning

This a sample demo, the signer does blind signing, use only with test keys (never with personal or other keys in production)!

How to run

  • Run the client
cd noco-client
cargo run

OR

cd noco-client-ui
cargo run
  • Run the server (from another session)
cd noco-signer
cargo run
  • Optionally you may want to set your own relay, in noco-client/src/main.rs APP_RELAY
  • You may want to use a different client app key (APP_SECRET_KEY)
  • If you do any change like the above, you need to copy paste the Nostr Connect URI from the output of the client, to noco-signer/src/main.rs SAMPLE_NOSTR_CONNECT_URL
  • You may want to use different keys for the signer (USER_SECRET_KEY)

Flow

The flow of events is something like this:

  • Signer connects to the client
  • Client accepts the connection
  • Client sends a Describe request
  • Signer replies
  • Client sends a GetPublicKey request
  • Signer replies
  • Client sends a SignEvent request -- on UI version this is triggered by a button
  • Signer signs and replies
  • Client publiches the resulting signed message

The NIP-46 + NIP-26 combo is also supported (client-ui):

  • Signer connects to the client
  • Client sends a Delegate request
  • Signer replies with a delegation tag, that is stored
  • Client can post a message directly, with the delegation tag
