## Nostr Wallet Connect (NWC)
|
|
|
|
Nostr Wallet Connect is like a bridge between your Lightning wallet and Nostr apps. It essentially works over three simple steps.
|
|
|
|
|
|
|
|
1. **Set up the connection**: Generate a connection string with your wallet. This connection string contains a public key, relay information, and a secret. This connection string is pasted into the Nostr app you want to use.
|
|
|
|
2. **Message over relays**: When you want to make a payment in the Nostr app, for example to send a zap, the app sends a request to the relay encrypted with the secret from the previous step. Your wallet listens on the same relay and picks up the request.
|
|
|
|
3. **Payment**: After receiving the request, the wallet makes the payment. This can be done automatically or require approval.

## Set up
|
|
|
|
Now that we have an understanding of how it works, let's configure some Nostr apps to use our Lightning wallet over NWC with the NWC Service Provider extension in LNbits.
|
|
|
|
0. **Enable the extension**: In the Extensions section in the sidebar, enable the NWC Service Provider extension. After enabling it, open it.
|
|
1. **Select a wallet**: It's a decent idea to create a wallet just for NWC if you want to separate it from your main wallet. You can easily do this by selecting "+ Add a new wallet" in the sidebar.
|
|
2. **Add a connection**: Click on the "+" and you can configure your connection settings, or just leave them at the default and add a description so you can later identify the connection. Once you're happy with the settings, click "Connect".
|
|
3. **Pairing**: You can now pair the Nostr app by pasting the connection string ("Pairing URL") or scanning the QR code with a compatible app.
|
|
|
|
That's it! Try it out by sending a zap.
