Popular on-chain sleuth ZachXBT warned earlier today that an admin address of Polymarket appeared to have been compromised on the Polygon blockchain.

At first, he noted that the stolen amount was around $520,000. However, follow-up updates from Bubblemaps and Lookonchain explained that the actual amount might have surpassed $600,000.

The attacker split the funds across 15 addresses after exploiting Polymarket’s UMA CFT adapter contract.

Polymarket’s Shantikiran Chanal acknowledged the attack on X, saying that the team is “aware of the security reports linked to rewards payout” before adding that “user funds and market resolutions are safe.”

Chanal also explained that the team is investigating whether any other internal secrets may have been affected and that they are rotating their backend services.
