📄️ AltZap Request
A kind 9520 AltZap Request is what a wallet signs to zap someone. It plays the role of NIP-57 ↗'s zap request (kind 9734), with two differences:
📄️ AltZap Receipt
A kind 9521 AltZap Receipt is what the recipient's LNURL server publishes once an invoice is paid. It is the public proof that a zap happened, like NIP-57's kind 9735.
📄️ On-Behalf AltZap Request
An AltZap request a proxy agent signs for someone without a Nostr key
📄️ Identity Connection
A kind 35521 Identity Connection is what a user publishes to say "my Nostr key owns this Discord (or X, email, …) account". On its own it proves nothing: it points to an IA Attestation (kind 35522), signed by an Identity Authority that checked the claim.
📄️ IA Attestation
A kind 35522 IA Attestation is an Identity Authority's signed statement: "Nostr key X owns web identity account Y." Users point to it from their Identity Connection (kind 35521).
📄️ LNURL Integration
AltZap implements the open LUD-06 and LUD-16 standards to bridge Lightning Network wallets with Nostr identity resolution. The protocol rules — chain advertisement and the callback — are in NIP-AZ; this page is how Zapf applies them.
