Connect to Wallet

This feature allows you to connect to a user's Ethereum wallet using various connectors like MetaMask. The code sample demonstrates how to use the `connect` function to establish a connection.

const { connect } = require('@wagmi/core');

async function connectWallet() {
  const { data, error } = await connect({ connector: new InjectedConnector() });
  if (error) console.error(error);
  else console.log('Connected:', data);
}

Fetch Blockchain Data

This feature allows you to fetch data from the blockchain, such as account balances. The code sample shows how to use the `useAccount` and `useBalance` hooks to retrieve and log the balance of the connected account.

const { useAccount, useBalance } = require('@wagmi/core');

function fetchBalance() {
  const { data: accountData } = useAccount();
  const { data: balanceData } = useBalance({ addressOrName: accountData?.address });
  console.log('Balance:', balanceData);
}

Execute Transactions

This feature allows you to execute transactions on the Ethereum blockchain. The code sample demonstrates how to use the `useSendTransaction` hook to send 1 ETH to a specified address.

const { useSendTransaction } = require('@wagmi/core');

function sendTransaction() {
  const { sendTransaction } = useSendTransaction();
  sendTransaction({
    request: {
      to: '0xRecipientAddress',
      value: '1000000000000000000', // 1 ETH in wei
    },
  }).then((result) => console.log('Transaction sent:', result));
