What is polymarket-arbitrage-bot?

This TypeScript bot automates a dump-and-hedge arbitrage strategy on Polymarket's 15-minute Up/Down markets for assets like BTC, ETH, SOL, and XRP. It polls orderbooks via Polymarket's CLOB and Gamma APIs, detects sharp price dumps in the opening minutes, buys the dipped side, then hedges the opposite when the combined cost hits your target (e.g., under $0.95 per pair) for locked-in profit on resolution. Run it in simulation mode by default with `npm start` to test without risk, or flip to production via `.env` for real Polygon wallet trades and USDC redemptions.

Why is it gaining traction?

With 93 stars on GitHub, this polymarket arbitrage trading bot stands out for its dead-simple `.env` setup—no code changes needed for shares, thresholds, or multi-asset monitoring—and built-in safeguards like time-based stop-loss hedging and P&L tracking in append-only logs. Developers dig the dry-run mode that mirrors real execution, plus proxy wallet support for GnosisSafe users, making it a quick pivot from manual Polymarket trading bots to automated crypto arbitrage on prediction markets.

Who should use this?

Polymarket traders hunting low-risk arb ops on 15m sports betting-style markets, or Polygon devs scripting CLOB order flows without starting from scratch. Ideal for quant hobbyists tweaking dump thresholds for BTC/ETH volatility, or teams backtesting strategies before live deployment on Polymarket's websocket-enabled API.

Verdict

Solid starter for Polymarket github bot experiments—excellent README and config docs make it approachable despite 93 stars and 1.0% credibility score signaling early maturity. Test extensively in sim mode first; add your own backtesting for production confidence.
