RFC: Cashu zaps NIP https://wikifreedia.xyz/cashu-zap-nip/f7z.io Proposal to make cashu zaps where the payment itself is the zap (instead of waiting for a zap receipt from the zapper) The sender locks a zap to the recipient's pubkey, optionally sending to a mint the user has recommended before (kind:38000).
