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.
