    { name: "Talisman", url: "https://www.talisman.xyz/" },
    { name: "MetaMask", url: "https://metamask.io" },

// initialize Onboard
init({
  wallets,
  chains,
  appMetadata,
});

const [{ wallet, connecting }, connect, disconnect] = useConnectWallet();

// create an ethers provider
let ethersProvider;

if (wallet) {
  ethersProvider = new ethers.providers.Web3Provider(wallet.provider, "any");
}

Use​

Now you only need a button to connect and activate the wallet.

<button
  disabled={connecting}
  onClick={() => (wallet ? disconnect(wallet) : connect())}
>
  {connecting ? "connecting" : wallet ? "disconnect" : "connect"}
</button>

And of course if you want to know how to tweak this library more, just look at the Web3-Onboard documentation.
