@ -166,18 +166,22 @@ A client can retrieve `zap receipt`s on events and pubkeys using a NIP-01 filter
- The `invoiceAmount` contained in the `bolt11` tag of the `zap receipt` MUST equal the `amount` tag of the `zap request` (if present). - The `invoiceAmount` contained in the `bolt11` tag of the `zap receipt` MUST equal the `amount` tag of the `zap request` (if present).
- The `lnurl` tag of the `zap request` (if present) SHOULD equal the recipient's `lnurl`. - The `lnurl` tag of the `zap request` (if present) SHOULD equal the recipient's `lnurl`.
### Appendix G: `zap` tag on zapped event ### Appendix G: `zap` tag on other events
When an event includes a `zap` tag, clients SHOULD calculate the lnurl pay request based on its value instead of the profile's field. An optional third argument on the tag specifies the type of value, either `lud06` or `lud16`. When an event includes one or more `zap` tags, clients wishing to zap it SHOULD calculate the lnurl pay request based on the tags value instead of the event author's profile field. The tag's second argument is the `hex` string of the receiver's pub key and the third argument is the relay to download the receiver's metadata (Kind-0). An optional fourth parameter specifies the weight (a generalization of a percentage) assigned to the respective receiver. Clients should parse all weights, calculate a sum, and then a percentage to each receiver. If weights are not present, CLIENTS should equally divide the zap amount to all receivers. If weights are only partially present, receivers without a weight should not be zapped (`weight = 0`).
```json ```js

"tags": [ "tags": [

} }
``` ```
Clients MAY display the zap split configuration in the note.

Zaps can be extended to be more private by encrypting `zap request` notes to the target user, but for simplicity it has been left out of this initial draft.
