There's a lot of potential with this. I'd prefer it to be over lightning though. Something static like a bolt12 address.

Nostr uses the same cryptography to generate keys as bitcoin. So, users can generate new keys from npub and receive bitcoin payments.

Alice would generate a new key for Bob and share the notification as encrypted message using NIP-17. Bob’s wallet will save the details to receive payments from Alice in future. Alice will get a new address for Bob by incrementing counter.
