Liquidity Sniper Bot

A precision liquidity sniper bot that detects the exact moment liquidity is added to a DEX pair and buys in block 0 before anyone else.

Liquidity Detection:

• Monitor PairCreated() events in real-time
• AddLiquidity() transaction detection
• Mempool monitoring for pending liquidity txns
• Multi-DEX: Uniswap, Pancake, Raydium, Jupiter
• Custom token address watchlist

Block 0 Sniping:

• Pre-signed transaction ready to fire
• Gas bidding strategy for priority inclusion
• Flashbots/Jito bundle submission
• Sub-second execution from detection to buy
• Configurable buy amount and slippage

Anti-Rug Protection:

• Contract source code verification check
• Honeypot detection (simulate sell before buy)
• Tax analysis (buy/sell tax check)
• Liquidity lock verification
• Owner renounce check
• Blacklist function detection

Auto-Sell Triggers:

• Take profit at 2x, 5x, 10x (configurable)
• Trailing stop loss
• Liquidity removal detection → instant sell
• Time-based sell (sell after X minutes)
• Rug detection → emergency sell

Tech Stack:

• TypeScript + ethers.js
• WebSocket mempool monitoring
• Flashbots/Jito SDK
