Main code

src/handler/tipping.ts

  );
  let amount: number = 0,
    receivers: User[] = [];

    context.reply("Sender or receiver or amount not found.");
    return;
  }
  const receiverAddresses = receivers.map((receiver) => receiver.address);
  // Process sending tokens to each receiver
  context.sendTo(
