This is a #nostr #safebox zap to a nip05 address. Doesn't look like much but there is a lot going behind the scenes. The npub is resolved using nip05, the kind 0 event is looked up and the lud16 is taken from the profile. A lightning invoice is requested for the zap amount, the #safebox wallet gets the right proofs to melt from the mint and provides the invoice to pay.
