tl;dr

Nostr Wallet Connect (NWC) is a way for applications like Nostr clients to access a remote Lightning wallet through a standardized protocol. For instance, you can link your Alby account with any other application using this feature.

How to connect your app?

1. Create a new app connection

   Enable the application by creating a permissioned connection to your wallet. This access can be revoked at any time.

2. Connect your app

   Connect your application by adding the connection secret. Either by scanning the connect QR code or clicking a link.

3. Done

   Zapp and Boost! Your lightning wallet is available where you need it.
   And if you ever want to disable it again, simply disconnect the connection again.
