Overview

  • Integration pairs Chainlink Data Streams’ low-latency, timestamped prices with Chainlink Automation to trigger on-chain settlement at preset times.
  • The rollout is live on Polygon for crypto price markets, including 15-minute up-or-down contracts across hundreds of trading pairs.
  • Outcomes now anchor to deterministic oracle data to reduce delays, disputes, and governance attacks seen under UMA’s optimistic oracle.
  • Both firms are researching ways to extend automated resolution to subjective questions, which they acknowledge remain technically challenging.
  • The upgrade aligns with Polymarket’s expansion plans, following its $112 million purchase of CFTC-licensed QCEX to support a U.S. return, as Chainlink cites nearly $100 billion in DeFi value secured.
