Polymarket said user funds and market resolution were safe after a suspected private key compromise tied to top-up operations.
Polymarket confirmed a security exploit affected part of its infrastructure, pointing to a possible private key compromise involving a wallet used for top-up operations, while saying user funds and market resolution were safe.
In a Friday X post, Polymarket developers said contracts and core infrastructure were unaffected. Polymarket product lead Akanshu Jain and multiple other Polymarket employees also said user funds and market resolution are safe.
Blockchain investigator ZachXBT first flagged the exploit as a compromise to the Polymarket-linked UMA Conditional Tokens Framework (CTF) Adapter contract on Polygon, with the exploiter draining at least $520,000.
