Nostr Zap Integration

Overview

Build correct Lightning Zap and Nutzap flows for Nostr applications. This skill covers the full NIP-57 lifecycle (LNURL discovery, zap request construction, invoice handling, zap receipt validation) and the NIP-61 Cashu alternative (nutzap configuration, P2PK token minting, nutzap publishing and redemption).

When to Use

• The task involves NIP-57 zaps or NIP-61 nutzaps in a Nostr application.
• The user needs zap requests, receipts, LNURL-pay integration, zap splits, recipient config, or Cashu token flow tied to Nostr events.
• The problem is payment interoperability between Nostr and Lightning/Cashu, not general wallet construction.
• The request is about end-to-end zap behavior or zap validation.
