Nostr Connect
|
|
-------------
|
|
|
|
`draft` `optional`
|
|
|
|
This NIP describes a method for 2-way communication between a **remote signer** and a normal Nostr client. The remote signer could be, for example, a hardware device dedicated to signing Nostr events, while the client is a normal Nostr client.
|
|
|
|
## Signer Discovery
|
|
|
|
The client must somehow be able to contact the signer through a common relay.
|
|
|
|
### Started by the signer
|
|
|
|
The remote signer generates a connection token in the form
|
|
|
|
```
|
|
<npub1...>#<secret>?relay=wss://...&relay=wss://...
|
|
```
|
|
|
|
The user copies that token and pastes it in the client UI somehow. Then the client can send events of kind `24133` to the specified relays and wait for responses from the remote signer.
|
|
|
|
### Started by the client
|
|
|
|
The client generates a QR code in the following form (URL-encoded):
|
|
|
|
```
|
|
nostrconnect://<client-key-hex>?relay=wss://...&metadata={"name":"client-name"}
|
|
```
|
|
|
|
The signer scans the QR code and sends a `connect` message to the client in the specified relays.
|
|
|
|
## Event payloads
|
|
|
|
Event payloads are [NIP-04](04.md)-encrypted JSON blobs that look like JSONRPC.
|
|
|
|
Events sent by the client to the remote signer have the following format:
|
|
|
|
```js
|
|
{
|
|
"pubkey": "<client-key-hex>"
|
|
"kind": 24133,
|
|
"tags": [
|
|
["p", "<signer-key-hex>"]
|
|
],
|
|
"content": "nip04_encrypted_json({id: <random-string>, method: <see-below>, params: []})",
|
|
...
|
|
}
|
|
```
|
|
|
|
And the events the remote signer sends to the client have the following format:
|
|
|
|
```js
|
|
"pubkey": "<signer-key-hex>"
|
|
"kind": 24133,
|
|
"tags": [
|
|
["p", "<client-key-hex>"]
|
|
],
|
|
"content": "nip04_encrypted_json({id: <request-id>, result: <any>, error: <reason-string>})",
|
|
...
|
|
```
|
|
|
|
