# WalletConnect Unsupported Chain

<img width="700px" src="https://mintlify.s3.us-west-1.amazonaws.com/dynamic-docs-feat-sidebar-revamp/images/walletconnect-unsupported-chain.png" alt="walletconnect-unsupported-chain" />

A common error encountered when using WalletConnect is `Unsupported chain`. This error occurs when the chain ID of the network you are trying to connect to is different than the chain specified by the WalletConnect provider.

```
UnknownRPCError: An unknown RPC error occurred.

Details: Unsupported chain
```

To resolve the above error, the `DynamicContextProvider` can be configured to dynamically change the desired WalletConnect chain ID of the network you are trying to connect to using the `walletConnectPreferredChains` property. [See here](/react-sdk/providers/dynamiccontextprovider#settings)

```jsx
<DynamicContextProvider
walletConnectPreferredChains={['eip155:1']}
... // additional parameters
/>
```
