How do you think those other options look?
My brain can only think as far as NFC sends or Nostr DM retrievals. As a side note, I’m surprised someone hasn’t come up with a way to send a lightning payment to meatspace geo-coordinates yet, to be collected or returned if not collected. But that’s probably insecure & gimmicky.
Nostr native browsers may help us close that gap too. Something Will and I’m sure others are working on. But that’s mostly just the same concept bundled into a different delivery method.
Alby has moved us forward immensely but I sense is about to come under custodial and security pressures, hence the question. But now you have me thinking bigger.
