    // Fund the sending wallet.

    // Check the account balances before making the transfer.
    final balance = await connection.getBalance(wallet1.pubkey);
    print('Account $address1 has an initial balance of $balance lamports.');

    // Fetch the latest blockhash.

    // Create a System Program instruction to transfer 0.5 SOL from [address1] to [address2].
