Token Sending Bot with Low Gas Fee

A Node.js bot for minting and sending ERC20 tokens with optimized gas fees on the Ethereum network.

Features

• Mint new ERC20 tokens to multiple addresses
• Send existing tokens to multiple addresses
• Optimized gas fee calculations
• Transaction tracking and retry mechanism
• Environment-based configuration
• Support for custom RPC endpoints
• Automatic tracking of sent tokens to prevent duplicate transactions

Installation

npm install token-sending-bot

Configuration

Create a .env file in your project root:

# Ethereum Configuration
ETH_NODE_RPC_URL=https://rpc.katla.taiko.xyz
SENDER_ADDRESS=your_wallet_address_here
PRIVATE_KEY=your_private_key_here
CONTRACT_ADDRESS=your_token_contract_address_here

Usage

1. Create a wallets.js file with recipient addresses:

const wallets = [
    '0x742d35Cc6634C0532925a3b844Bc454e4438f44e',
    '0x123f681646d4A755815f9CB19e1aCc8565a0c2AC'
];

module.exports = wallets;

2. Run the bot:

npm start

How It Works

The bot performs the following operations:

1. Token Minting:

   • Mints random amounts of tokens (1-1000) to each address in the wallets list
   • Automatically handles token decimals
   • Tracks minted addresses to prevent duplicate minting

2. Transaction Management:

   • Calculates optimal gas fees
   • Handles transaction retries if needed
   • Maintains a record of successful transactions

3. Progress Tracking:

   • Creates a received_addresses.json file to track successful transactions
   • Skips addresses that have already received tokens
   • Provides console output for monitoring progress

Important Notes

• The sender address must have minting permissions on the token contract
• The sender address must have enough ETH for gas fees
• The bot will automatically retry failed transactions
• Each address will receive a random amount of tokens between 1 and 1000

Security

• Never commit your .env file
• Keep your private keys secure
• Use environment variables for sensitive data
• The bot automatically tracks sent tokens to prevent duplicate transactions
