To switch the network of a connected wallet, first find the corresponding ConnectedWallet object from the wallets array.

const {wallets} = useWallets();
const wallet = wallets[0]; // Replace this with your desired wallet

Then, call the wallet’s switchChain method. As a parameter to the method, pass the chain ID for your desired network as a number or hexadecimal string:

await wallet.switchChain(7777777);

For embedded wallets, switchChain will update the network of the embedded wallet behind the scenes. For external wallets, switchChain will prompt the user to switch to the target network within the external wallet’s client (e.g. their browser extension or mobile app).

switchChain returns a Promise that resolves to void once the wallet has successfully been switched to the target network. The Promise will reject with an error if:

• The target chain has not been configured.
• The user declines the request to switch their network, if using an external wallet.

By default, embedded wallets will be connected to the first network specified in your supportedChains array, and to Ethereum mainnet if no supportedChains are specified.

To switch the embedded wallet to a different network, send a wallet_switchEthereumChain JSON-RPC request to the wallet’s EIP-1193 provider. In the request’s params, specify your target chainId as a hexadecimal string.

const provider = await wallet.getProvider();
await provider.request({
  method: 'wallet_switchEthereumChain',
  // Replace '0x5' with the chainId of your target network
  params: [{chainId: '0x5'}]
});

You can also use the eth_chainId request (with no params) to get the current network of the embedded wallet.
