This is cool. Although, sending something to your nostr identity could open up some correlation and timing attacks, I suppose.
I wonder if we could do something just like in silent payments where you create a shared private key, and send payment details over Nostr to that instead encrypted.
That way they can be correlation and timing attacks but there's nothing correlating these payments to anyone's specific identity and nothing tying them together.
People still probably want to access these over tour with unique identities. to ensure that there's no correlation being tracked by nostr relays.
