This project provides a robust NIP-42 proxy for Nostr relays, creating an authentication layer to ensure only authorized users can connect and interact with a public relay.
## ✨ Features
- **NIP-42 Authentication**: Enforces NIP-42 authentication, securing your relay from unauthorized access.
- **Proxy Layer**: Seamlessly forwards messages between authenticated clients and the main relay.
- **Dynamic Whitelist**: Manage allowed public keys and event kinds on-the-fly via an admin RPC interface.
- **Admin RPC Interface**: A NIP-98-protected RPC interface for easy administration.
- **Containerized**: Comes with a `Dockerfile` for easy and consistent deployment.
- **Fast & Modern**: Built with Bun for optimal performance.
## 🚀 Getting Started
### Prerequisites
- [Bun](https://bun.sh/)
- [Docker](https://www.docker.com/) (Optional)
### Installation & Running
1. **Clone the repository:**
```bash
git clone https://git.arx-ccn.com/Arx/nip42-proxy.git
cd nip42-proxy
```
2. **Install dependencies:**
```bash
bun install
```
3. **Run the proxy:**
* **With Bun:**
```bash
RELAY_URL="wss://my-relay.com" ADMIN_PUBKEY="my-admin-pubkey" bun run index.ts
```
* **With Docker:**
1. Build the image:
```bash
docker build -t nip42-proxy .
```
2. Run the container:
```bash
docker run -p 3000:3000 -e RELAY_URL="wss://your-relay-url.com" -e ADMIN_PUBKEY="my-admin-pubkey" --name nip42-proxy nip42-proxy
```
The server will start, and you can connect to it using a Nostr client that supports NIP-42 authentication.
## ⚙️ Configuration
The proxy is configured through environment variables.

| Variable | Description | Default |
| ----------------------- | ------------------------------------------------------------------------------------------------------- | --------- |
| `ALLOW_UNAUTHED_PUBLISH`| Set to `true` to allow unauthenticated clients to publish events. | `false` |
| `RELAY_URL` | The URL of the relay that the proxy will connect to. | |
| `RELAY_OUTSIDE_URL` | The URL that clients use to connect to the proxy. | `RELAY_URL` |
| `RELAY_NAME` | The name of the relay. | |
| `RELAY_DESCRIPTION` | A description of the relay. | |
| `RELAY_BANNER` | A URL to a banner image for the relay. | |
| `RELAY_ICON` | A URL to an icon for the relay. | |
| `RELAY_CONTACT` | A contact email or address for the relay. | |
| `RELAY_POLICY` | A URL to the relay's policy document. | |
| `ADMIN_PUBKEY` | The public key of the administrator of the relay. | |
## 🔧 Admin RPC Interface
The proxy exposes a NIP-98-protected RPC interface for administration. Send a `POST` request to the root URL (`/`) with `Content-Type: application/nostr+json+rpc` and a NIP-98 token in the `Authorization` header.
**Available Methods:**
- `supportedmethods`: Get a list of supported RPC methods.
- `getinfo`: Get the relay's information document.
- `banpubkey`: Ban a public key.
- `allowpubkey`: Allow a public key.
- `listallowedpubkeys`: List all allowed public keys.
- `allowkind`: Allow a specific event kind.
- `disallowkind`: Disallow a specific event kind.
- `listallowedkinds`: List all allowed event kinds.
## 🤔 How It Works
1. **Client Connection**: A client connects to the proxy and is initially unauthenticated.
2. **Authentication Request**: The proxy sends an `AUTH` challenge.
3. **Client Authentication**: The client responds with a valid `AUTH` event, signed with an allowed public key.
4. **Authenticated State**: The client is now authenticated and can interact with the relay.
5. **Message Forwarding**: Messages are forwarded between the client and the main relay.
