Documentation
Polymarket Auto-Trader
Fully autonomous prediction market trading agent for Polymarket. Evaluates markets using LLM probability estimation, sizes positions with Kelly criterion, and executes trades via the Polymarket CLOB API from a non-US VPS.
Prerequisites
Non-US VPS โ Polymarket blocks US IPs. Use DigitalOcean Amsterdam, Hetzner EU, etc. Polygon wallet with USDC.e (bridged USDC, NOT native USDC) MATIC for gas (~0.1 MATIC sufficient for hundreds of trades) Anthropic API key (uses Haiku at ~$0.001/evaluation)
1. VPS Environment
SSH into your non-US VPS and run: python3 {baseDir}/scripts/setup_vps.sh Or manually: apt update && apt install -y python3 python3-venv python3 -m venv /opt/trader /opt/trader/bin/pip install py-clob-client python-dotenv web3 requests
2. Configuration
Create /opt/trader/app/.env: PRIVATE_KEY=<your-polygon-wallet-private-key> LLM_API_KEY=<your-anthropic-api-key>
3. Blockchain Approvals
Before trading, approve USDC.e and CTF tokens for Polymarket contracts. Run: python3 {baseDir}/scripts/approve_contracts.py Required approvals (6 total): USDC.e โ CTF Exchange, Neg Risk Exchange, Neg Risk Adapter CTF โ CTF Exchange, Neg Risk Exchange, Neg Risk Adapter
4. Deploy Trading Script
cp {baseDir}/scripts/run_trade.py /opt/trader/app/ cp {baseDir}/scripts/pnl_tracker.py /opt/trader/app/
5. Cron Automation
crontab -e # Add: */10 * * * * cd /opt/trader/app && /opt/trader/bin/python3 run_trade.py >> cron.log 2>&1
How It Works
Market Scan โ Fetches active markets from Gamma API, filters by liquidity and time horizon LLM Evaluation โ Asks Claude Haiku to estimate true probability for each market Edge Detection โ Compares LLM fair value vs market price (min 5% edge threshold) Kelly Sizing โ Half-Kelly criterion with 25% max position size cap Order Execution โ Places limit orders via CLOB API with GTC (good-till-cancelled) Dedup โ Tracks all trades in trades.jsonl, skips already-traded markets Budget Control โ Tracks LLM inference costs separately from trading capital
Trading Parameters
Configurable in run_trade.py: EDGE_THRESHOLD โ Minimum edge to trade (default: 0.05 = 5%) MIN_SHARES โ Minimum order size (Polymarket requires โฅ5 shares) Bankroll allocation: 80% usable, 25% max per trade, 30% cap per single position Market horizon: Prioritizes markets ending within 30 days
Monitoring
Check P&L anytime: python3 /opt/trader/app/pnl_tracker.py Check recent activity: tail -50 /opt/trader/app/cron.log
Key Technical Details
Wallet type: EOA (signature_type=0), NOT proxy wallet Token: USDC.e (0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174), not native USDC Neg-risk markets (elections, sports leagues) require USDC.e approval for Neg Risk Adapter (0xd91E80cF2E7be2e162c6513ceD06f1dD0dA35296) US geoblock โ All API calls must originate from non-US IP. VPN insufficient; use actual non-US VPS.
Cost
LLM inference: ~$0.001 per market evaluation (Haiku) Typical cycle (40 evals): ~$0.04 Gas: negligible on Polygon (~$0.001 per trade)
โ ๏ธ Security Considerations
Use a DEDICATED wallet with minimal funds. Never use your main wallet's private key. Create a fresh wallet and fund it only with what you're willing to risk. PRIVATE_KEY is stored on disk in .env. Harden your VPS: strict file permissions (chmod 600 .env), no shared access, firewall, SSH keys only. MAX_UINT approvals are standard in DeFi but grant broad spending rights. The approved contracts are official Polymarket contracts. Review addresses in references/contract-addresses.md before running. Test with tiny amounts first ($5-10) before scaling up. Monitor actively โ check cron.log and run pnl_tracker.py regularly. LLM_API_KEY billing โ each cycle costs ~$0.04 (Haiku). Set billing alerts on your Anthropic account. This is autonomous trading software. Bugs or market conditions can cause losses. Use at your own risk.
