const run = async () => {
  const connection = new Connection(
    `https://rpc.hellomoon.io/${process.env.HELLOMOON_API_KEY}`, // REPLACE process.env.HELLOMOON_API_KEY with your API key
  );

  const balance = await connection.getBalance(
    new PublicKey("ANY_PUBLIC_KEY")
  );
  console.log(`Your Solana Balance is ${balance / LAMPORTS_PER_SOL} SOL`);
