const Connection = solanaWeb3.Connection
const Transaction = solanaWeb3.Transaction
const network = "<NETWORK_URL>";
const connection = new Connection(network);
const transaction = new Transaction();
const { signature } = window.solana.signAndSendTransaction(transaction);
connection.confirmTransaction(signature);
console.log(solanaWeb3);
