Polymarket Hack Suspected After $520K Exploit on Polygon

Blockchain investigator ZachXBT flagged a suspected attack targeting Polymarket on the Polygon network. The exploit reportedly affected the platform’s UMA CTF Adapter contract and caused losses exceeding $520,000. The attacker’s wallet and impacted contract addresses have already been identified by on-chain analysts. The incident matters because Polymarket is the world’s largest crypto prediction market, and another security breach could raise fresh concerns about smart contract risks and user fund protection in decentralized platforms.
