## Nutzap event ## Nutzap event
Event `kind:7337` is a nutzap event published by the sender, p-tagging the recipient. The outputs are P2PK-locked to the pubkey the recipient indicated in their `kind:10019` event or to the recipient pubkey if the `kind:10019` event doesn't have a explicit pubkey. Event `kind:7337` is a nutzap event published by the sender, p-tagging the recipient. The outputs are P2PK-locked to the pubkey the recipient indicated in their `kind:10019` event or to the recipient pubkey if the `kind:10019` event doesn't have a explicit pubkey.
Clients MUST prefix the recipient pubkey with `"02"` (for nostr<>cashu pubkey compatibility). Clients MUST prefix the pubkey they p2pk-lock with `"02"` (for nostr<>cashu pubkey compatibility).
