This is a comprehensive integration for building on Polymarket's prediction markets on Polygon. It covers the full stack: L1/L2 authentication with EIP-712 and HMAC signatures, order placement with all the standard types (GTC, GTD, FOK, FAK), real-time WebSocket feeds for orderbook and user events, and CTF token operations for splitting and merging positions. The skill includes contract addresses, both TypeScript and Python SDK examples, and detailed references for gasless transactions through their relayer. If you're building an AI trading agent or a custom prediction market interface, this gets you up and running without hunting through docs. The negative risk market support is a nice touch for multi-outcome events.
