## Zap Goals
|
||
|
|

|
`draft` `optional` `author:verbiricha`
|
||
|
|
||
|
This NIP defines an event for creating fundraising goals. Users can contribute funds towards the goal by zapping the goal event.
|
||
|
|
||
|
## Nostr Event
|
||
|
|
||
|
A `kind:9041` event is used.
|
||
|
|
||
|
The `.content` contains a human-readable description of the goal.
|
||
|
|
||
|
The following tags are defined as REQUIRED.
|
||
|
|
||
|
- `amount` - target amount in milisats.
|
||
|
- `relays` - a list of relays the zaps to this goal will be sent to and tallied from.
|
||
|
|
||
|
Example event:
|
||
|
|
||
|
```json
|
||
|
{
|
||
|
"kind": 9041,
|
||
|
"tags": [
|
||
|
["relays", "wss://alicerelay.example.com", "wss://bobrelay.example.com", ...],
|
||
|
["amount", "210000"],
|
||
|
],
|
||
|
"content": "Nostrasia travel expenses",
|
||
|
...other fields
|
||
|
```
|
||
|
|
||
|
The following tags are OPTIONAL.
|
||
|
|
||
|
- `closed_at` - timestamp for determining which zaps are included in the tally. Zap receipts published after the `closed_at` timestamp SHOULD NOT count towards the goal progress.
|
||
|
|
||
|
```json
|
||
|
{
|
||
|
"kind": 9041,
|
||
|
"tags": [
|
||
|
["relays", "wss://alicerelay.example.com", "wss://bobrelay.example.com", ...],
|
||
|
["amount", "210000"],
|
||
|
["closed_at", "<unix timestamp in seconds>"],
|
||
|
],
|
||
|
"content": "Nostrasia travel expenses",
|
||
|
...other fields
|
||
|
```
|
||
|
|
||
|
The goal MAY include an `r` or `a` tag linking to a URL or parameterized replaceable event.
|
||
|
|
||
|
The goal MAY include multiple beneficiary pubkeys by specifying [`zap` tags](57.md#appendix-g-zap-tag-on-other-events).
|
||
|
|
||
|
Parameterized replaceable events can link to a goal by using a `goal` tag specifying the event id and an optional relay hint.
|
||
|
|
||
|
```json
|
||
|
{
|
||
|
"kind": 3XXXX,
|
||
|
"tags": [
|
||
|
...
|
||
|
["goal", "<event id>", "<Relay URL (optional)>"],
|
||
|
],
|
||
|
...other fields
|
||
|
```
|
||
|
|
||
|
## Client behavior
|
||
|
|
||
|
Clients MAY display funding goals on user profiles.
|
||
|
|
||
|
When zapping a goal event, clients MUST include the relays in the `relays` tag of the goal event in the zap request `relays` tag.
|
||
|
|
||
|
When zapping a parameterized replaceable event with a `goal` tag, clients SHOULD tag the goal event id in the `e` tag of the zap request.
|
||
|
|
||
|
## Use cases
|
||
|
|
||
|
- Fundraising clients
|
||
|
- Adding funding goals to events such as long form posts, badges or live streams
