send_bulk ========= .. code-block:: python async def send_bulk(mnemonic: str, destinations: list[dict] ) -> str: Send TON tokens to multiple recipients in a single transaction using the HighloadWalletV2Contract. **Important:** Before using the `send_bulk` method, you must create and deploy a HighloadWalletV2Contract wallet. The default wallet will not work with this method. Ensure that the wallet has sufficient balance to deploy itself and cover the transaction fees. Parameters: - **mnemonic** (str): The mnemonic phrase of the sender's HighloadWalletV2Contract wallet. - **destinations** (list[dict]): A list of dictionaries representing the recipient information. Each dictionary should contain the following keys: - **address** (str): The TON blockchain address of the recipient. - **amount** (int): The amount of TON tokens to send to the recipient, in nano grams. - **payload** (str, optional): The payload (memo) to include with the transaction for the recipient. - **send_mode** (int, optional): The send mode for the transaction (default is 1). Returns: - **str**: The transaction hash of the sent bulk transaction. Example usage: .. code-block:: python from aiotx.utils.tonsdk.contract.wallet import WalletVersionEnum from aiotx.clients import AioTxTONClient import asyncio # Create a TON client with HighloadWalletV2Contract bulk_ton_client = AioTxTONClient( "https://testnet.toncenter.com/api/v2", workchain=0, wallet_version=WalletVersionEnum.hv2, ) # Define the list of recipients recipients_list = [ { "address": "0QAEhA1CupMp7uMOUfHHoh7sqAMNu1xQOydf8fQf-ATpkbpT", "amount": 1, "payload": "Hello, recipient 1!", "send_mode": 1, }, { "address": "UQDlTHD4T79EyT96gkYNKd3iuRd2__6gGh2PCKpU57jSWQ7j", "amount": 10, "payload": "Hello, recipient 5!", "send_mode": 1, }, ] # Deploy the HighloadWalletV2Contract wallet (required before sending) tx_id = await bulk_ton_client.deploy_wallet("your mnemonic phrase here") # Send TON tokens to multiple recipients using the send_bulk method tx_id = await bulk_ton_client.send_bulk( "your mnemonic phrase here", recipients_list, ) print("Transaction ID:", tx_id) In this example, we create a TON client with the HighloadWalletV2Contract wallet version. We define a list of recipients, each with their address, amount to send, payload (memo), and send mode. Before using the `send_bulk` method, we deploy the HighloadWalletV2Contract wallet using the `deploy_wallet` method and the sender's mnemonic phrase. This step is necessary to ensure the wallet is ready to send transactions. Finally, we call the `send_bulk` method with the sender's mnemonic phrase and the list of recipients. The method returns the transaction hash of the sent bulk transaction. Note: - Make sure to replace `"your mnemonic phrase here"` with the actual mnemonic phrase of the sender's HighloadWalletV2Contract wallet. - Ensure that the wallet has sufficient balance to cover the deployment costs and transaction fees.
