Setup

Environment Variables

To run this bot, you will need to configure the following environment variables:

Required Variables

• GRPC_ENDPOINT - Your Yellowstone gRPC endpoint URL
• GRPC_X_TOKEN - Your Yellowstone authentication token
• `` - Wallet address(es) to monitor for trades (comma-separated for multiple addresses)

Telegram Notifications

To enable Telegram notifications:

• TELEGRAM_BOT_TOKEN - Your Telegram bot token
• TELEGRAM_CHAT_ID - Your chat ID for receiving notifications

Optional Variables

• PROTOCOL_PREFERENCE - Preferred protocol to use (pumpfun, pumpswap, or auto for automatic detection)
• COUNTER_LIMIT - Maximum number of trades to execute

New Token Tracking System

The bot now includes a comprehensive token tracking system that:

1. Tracks Bought Tokens: When the bot successfully buys a token, it's added to a tracking system
2. Prevents Invalid Sells: The bot will only attempt to sell tokens it actually owns
3. Monitors Balances: A background service checks token balances every 30 seconds
4. Auto-Cleanup: Tokens with zero or very low balances are automatically removed from tracking

Commands

• --check-tokens: Display current token tracking status
• --wrap: Wrap SOL to WSOL
• --unwrap: Unwrap WSOL to SOL
• --close: Close all token accounts

Usage

# Build the project
cargo build --release

# Run the bot
cargo run --release

Once started, the bot will:

1. Connect to the Yellowstone gRPC endpoint
2. Monitor transactions from the specified wallet address(es)
3. Automatically copy buy and sell transactions as they occur
4. Send notifications via Telegram for detected transactions and executed trades

Recent Updates

• Added PumpSwap notification mode (can monitor without executing trades)
• Implemented concurrent transaction processing using tokio tasks
• Enhanced error handling and reporting
• Improved selling strategy implementation
