High-performance TypeScript bot that monitors wallets and DEX activity on Solana and automatically copies/snipes trades. Supports PumpFun, PumpSwap (notify-only by default), Raydium launchpad, configurable selling engine with dynamic trailing stops, and Jupiter for token liquidation.

Key Features

• Real-time monitoring: Yellowstone gRPC stream, parallel target-wallet + DEX monitors
• Redis queue: ioredis decouples stream detection from trade execution
• Protocols: PumpFun (trade), PumpSwap (notify-only by default)
• Copy trading: Follow one or many target wallets with exclusions
• Risk & selling: Take profit, stop loss, dynamic trailing stop, copy-selling
• Tx landing: ZeroSlot or normal mode, configurable priority fees
• Utilities: Wrap/unwrap SOL, close empty token accounts, sell all tokens via Jupiter
