# Custom RPC URLs

# EVM

You can override the RPC url of any EVM network by using the [`overrideNetworkRpcUrl`](/react-sdk/utilities/overridenetworkrpcurl) method in combination with the `overrides.evmNetworks` settings.

## Example

The following example overrides the RPC url of the Ethereum mainnet and Polygon set in the dashboard with the ones set in the `rpcUrlOverrides` object.

```TypeScript
const rpcUrlOverrides = {
    "1": ["https://eth.customrpc.com"],
    "137": ["https://polygon.customrpc.com"]
}

const App = () => (
  <DynamicContextProvider
    settings={{
      environmentId: 'REPLACE_WITH_YOUR_ENV_ID',
      overrides: {
        evmNetworks: (networks) => overrideNetworkRpcUrl(networks, rpcUrlOverrides),
      }
    }}
  >
    <Home />
  </DynamicContextProvider>
);

export default App;
```

# SVM (sdk v4.8.0+)

You can override the RPC url of any SVM network by using the [`overrideNetworkRpcUrl`](/react-sdk/utilities/overridenetworkrpcurl) method in combination with the `overrides.solNetworks` settings.

## Example

The following example overrides the RPC url of the Solana mainnet and Eclipse mainnet set in the dashboard with the ones set in the `rpcUrlOverrides` object.

```TypeScript
const rpcUrlOverrides = {
    "101": ["https://sol.customrpc.com"],
    "201": ["https://eclipse.customrpc.com"]
}

const App = () => (
  <DynamicContextProvider
    settings={{
      environmentId: 'REPLACE_WITH_YOUR_ENV_ID',
      overrides: {
        solNetworks: (networks) => overrideNetworkRpcUrl(networks, rpcUrlOverrides),
      }
    }}
  >
    <Home />
  </DynamicContextProvider>
);

export default App;
```
