Polymarket halts trading for an hour after DebugBear vendor breach
Polymarket paused trading on its international platform for nearly an hour Thursday after discovering that software from third-party vendor DebugBear had been compromised. The company said affected users would be fully reimbursed and referred the incident to UK law enforcement, while The Block reported roughly $2.65 million in crypto was drained from user wallets, citing Arkham data. Polymarket's US platform was reportedly unaffected, and trading resumed around 3 p.m. ET.
