JavaScript

const connectWallet = async () => {
  if (window.ethereum) {
    try {
      const addresses = await window.ethereum.request({
        method: 'eth_requestAccounts'
      });
      setAccount(addresses[0]);
    } catch (err) {
      console.error(err);
    }
  } else {
    alert('Install MetaMask!');
  }
