async function getWalletBalance(walletAddress) {

    const publicKey = new solanaWeb3.PublicKey(walletAddress);
    const balance = await connection.getBalance(publicKey);
    console.log(`Wallet Balance: ${balance / solanaWeb3.LAMPORTS_PER_SOL} SOL`);
  } catch (error) {
    console.error('Error fetching wallet balance:', error);
  }
}

// Replace with your Solana wallet address
const walletAddress = 'YourWalletAddressHere';
getWalletBalance(walletAddress);
