Binance BSC Smart Chain Token Creation Tutorial – Batch Transfer Tool and Detailed Operation Guide on BSC Chain

Preparation

1. Wallet Setup:

   • Prepare a dedicated wallet for batch transfers.
   • Ensure the wallet has sufficient BNB to cover gas fees.

2. Security Note:

   • Use a wallet exclusively for batch transfers (no stored assets).
   • Private key submission is required for tool authorization.

3. Transfer Limits:

   • Supports up to 30 simultaneous transfers to different addresses per batch.

Implementation Methods

Option 1: Third-Party Tools

• Pros: User-friendly interface.
• Cons: Requires private key submission, potential security risks.

Option 2: Built-In Contract Functionality

• Pros: No external tool dependency.
• Cons: Requires advanced contract coding.

Key Purposes of Batch Transfers

1. Gas Optimization: Consolidate multiple transactions.
2. Efficiency: Rapid token distribution without manual redundancy.

Step-by-Step Process

1. Token Quantity Authorization

• Enter authorization parameters (ensure values include token precision).

  • Example: For 100 tokens with 9 decimals, input 100000000000.

2. Authorization Verification

• Query the transaction hash on BSC Block Explorer.
• Confirmation: "Authorization Successful."

3. Execute Batch Transfers

• Input quantities in minimal units (including precision).
• Ensure total transfers ≤ authorized amount.

4. Transfer Verification

• Confirm successful transfers via block explorer.
• Example: "20,000 tokens received" across 30 wallets.

Batch Transfer Contract Code

pragma solidity ^0.4.23;
import './Erc20.sol';
import './SafeMath.sol';

contract BatchTransferContract {
    using SafeMath for uint256;
    address owner;

    constructor() public {
        owner = msg.sender;
    }

    function sendToken(address token, address[] recipients, uint256[] values) public payable {
        ERC20 erc20 = ERC20(token);
        uint256 total = 0;
        for (uint256 i = 0; i < recipients.length; i++) {
            erc20.transferFrom(msg.sender, recipients[i], values[i]);
            total += values[i];
        }
    }
}

FAQs

Q1: Is private key submission safe?

A: While convenient, it poses risks. Use dedicated wallets and revoke permissions post-transfer.

Q2: How to handle failed transfers?

A: Verify gas fees and authorized amounts. Retry with adjusted parameters.

Q3: Can I customize transfer limits?

A: Yes, modify the recipients.length loop in the contract.
