Architecture

Helius WebSocket → whale tx detected
        ↓
parseTransaction() → decode token changes
        ↓
Jupiter quote → can we route? 
        ↓ (if no route)
Pump.fun DAS check → bonding curve token?
        ↓
safety check → price impact < 50%?
        ↓
paper: log trade | live: executeRealSwap()
        ↓
Telegram alert sent

Key Files

• src/copy_trade.js — Core copy trader engine
• src/wallet_tracker.js — Helius WebSocket + tx parsing
• src/arbitrage.js — Jupiter arb scanner
• src/pumpfun.js — Pump.fun token metadata via Helius DAS
• src/sniper.js — New token sniper (paper mode)
• src/config.js — Wallet + connection setup

Live → Paper Switch

In copy_trade.js startCopyTrader():

paper: true   // paper mode (safe, no real money)
paper: false  // LIVE mode — real trades

Or use index.js mode copy (always paper) vs direct startCopyTrader({ paper: false }).

Safety Limits

• MAX_TRADE_SOL — max SOL per trade (default 0.01)
• maxPositions: 3 — max open positions at once
• priceImpact > 50% → skip (rug protection)
• Pump safety score < 40 → skip
