Polymarket is probing a security incident after attackers used a compromised internal Polygon wallet to siphon roughly $700,000 worth of POL.
Blockchain sleuth ZachXBT first flagged the exploit and identified connections to a Polymarket UMA CTF adapter contract.
The stolen funds were split across at least 15 addresses and routed through centralized exchanges and other services. According to onchain analytics platform Bubblemaps, attackers extracted around 5,000 POL every 30 seconds before suspicious withdrawals ceased.
UPDATE: ~$700k exploited
• Suspected withdrawals have stopped• Polymarket said the incident was isolated and user funds are safe
