# RPC
The JSON-RPC endpoint is `https://testrpc.dinx.io`. The chain ID inherited from ethereum is 1.
#### Add DINX RPC to MetaMask
You can add the DINX RPC endpoint in two ways: **automatically** or **manually**.
1. **Manual Setup via MetaMask:**
* Click on the MetaMask settings and add DINX as your RPC provider.
2. **Automatic Setup via URL:**
* You can switch to DINX by visiting[`https://explorer.dinx.io`](https://explorer.dinx.io) to easily configure your RPC.
Below is an example of how to add the DINX RPC programmatically:
```javascript
try {
await provider // Or window.ethereum if you don't support EIP-6963.
.request({
method: "wallet_switchEthereumChain",
params: [{ chainId: "0x1" }],
});
} catch (switchError) {
// This error code indicates that the chain has not been added to MetaMask.
if (switchError.code === 4902) {
try {
await provider // Or window.ethereum if you don't support EIP-6963.
.request({
method: "wallet_addEthereumChain",
params: [
{
chainId: "0x1",
chainName: "DINX",
rpcUrls: ["https://testrpc.dinx.io"], // DINX RPC endpoint
},
],
});
} catch (addError) {
// Handle any "add" error.
}
}
// Handle other "switch" errors.
}
```
**Note:** This process is just for switching your RPC provider and does not collect any personal information or introduce additional security risks.
