PANews reported on May 22 that, according to Bubblemaps, a contract related to the prediction market platform Polymarket was suspected of being compromised. Attackers transferred approximately 5,000 POL every 30 seconds, resulting in a total theft of about $600,000. On-chain analyst zachxbt pointed out that the affected address was a Polymarket UMA CTF adapter contract, and the attackers had dispersed the funds across 15 addresses. Polymarket subsequently responded that the issue stemmed from the leakage of a wallet private key used for internal operations and reward distribution. User funds and market settlement contracts were unaffected, and core infrastructure remains secure. Further updates will be released later.
