Polymarket Freezes $164,000 After Private Key Leak Triggers Unauthorized Transfers

Polymarket engineering VP Josh Stevens said $164,000 of the $573,200 moved after a private key was compromised has been frozen, following coordination among ZachXBT, Bitcoin Vietnam and ChangeNOW. Stevens reiterated that the incident did not involve an exploit of Polymarket or the UMA contract. He said user funds remain safe and Polymarket.com continues to operate normally. The transfers were traced to an internal funding setup tied to a six-year-old private key that was leaked, allowing funds to be sent to the address associated with that key.
