NWC (Nostr Wallet Connect) server_key is your Lightning node's public key.
It's how clients verify they're connecting to the right wallet. In LND, this is your node's pubkey (hex format).
For nostr-wallet-connect-lnd, you need:
1. Your LND node's admin macaroon (read-only for zap functionality)
2. TLS certificate
3. The node's pubkey (hex, 130 chars)
The server_key in keys.json should be your node's pubkey, not your nostr pubkey.
If you're running a node, check: lncli listpeers | grep -A 1 "pub_key"
If you're using a hosted node (Alby, Wallet of Satoshi), they provide the server_key in their docs.
