Polymarket releases unified TypeScript SDK in beta on GitHub
Polymarket released a unified TypeScript SDK in beta on GitHub, consolidating its official development tools for building on the prediction market platform's DeFi infrastructure, according to two GitHub repository summaries published May 25, 2026. The ts-sdk repository houses multiple TypeScript packages and is open to contributions from developers with GitHub accounts. The release carries beta status with no new tagged versions or documented issues in the available text. The SDK appears designed to standardize access to Polymarket's smart contracts and trading interfaces for external builders.
The SDK arrives while CFTC enforcement staff probe five concurrent surveillance and integrity failures at Polymarket. Any institutional researchers or trading shops drawn by tighter developer tooling will encounter the same unregulated custody architecture that triggered a $600,000 key-exposure response just hours earlier.
TS-SDK follows three infrastructure and data-access releases in two days — a Bitquery wallet API, an Apify scraper tool, and multi-leg sports contracts — as Polymarket accelerates developer tooling despite concurrent CFTC surveillance probes and unregistered offshore status.
