  Polymarket is a decentralized prediction-market platform built on Polygon
  where users buy and sell binary outcome shares in real-world events.
  Settlement is on-chain via the UMA optimistic oracle, while order matching
  runs through a hybrid central-limit order book (CLOB). Developer surface
  includes the CLOB API for order placement and market data, the Gamma API for
  market and event metadata, a Data API for historical and analytical reads, a
  WebSocket stream, and official CLOB client SDKs in TypeScript, Python, and
  Rust.
