Polymarket Restores Order Book Following Breach
Key Summary
Polymarket restored order-book trading on its international platform Tuesday afternoon after a third-party vendor security breach drained an estimated $2.7M in customer funds.
Key Bullets
- Polymarket restored active order-book trading on its international venue after an external security incident forced an emergency trading halt on October 29.
- On-chain forensic data compiled by Bubblemaps confirmed that hackers drained an estimated $2.71M through malicious code injected via a third-party monitoring service.
- Stolen user funds were converted directly into POL tokens and Ethereum before being fanned out across hundreds of distinct destination wallet addresses.
- Exchange operators promised full reimbursements to all impacted traders but omitted any specific claim filing procedures or compensation payout schedules.
Emergency Trading Halt Follows Breach
Polymarket restored trading operations on its international prediction platform Tuesday following an urgent security incident that forced an emergency shutdown. The platform restricted its order book to cancel-only mode moments after detecting unauthorized outflows. Transactions submitted on behalf of users were paused immediately. Order execution halted across all active prediction markets.
Exchange operators traced the vulnerability to an outside service provider. External monitoring tools compromised user sessions directly. Asset drainage followed within minutes. Trading resumed only after engineers severed the compromised vendor connection.
On-Chain Forensics Trace Stolen Funds
On-chain transaction data monitored by Bubblemaps confirmed that attackers stole roughly $2.71M from user accounts during the security lapse. Forensic traces followed hundreds of individual deposit wallets funneling assets into a primary attacker address. Stolen capital was converted directly into POL tokens. The converted assets were then distributed across multiple separate Ethereum wallets.
Independent code auditors linked the exploit vector to a compromised website performance-monitoring tool. Malicious scripts hijacked active user trading sessions. Unauthorized transactions executed silently behind the scenes. Polymarket administrators have yet to publish their internal post-mortem findings.
Full Reimbursement Promised To Users
Polymarket management published an update confirming that all affected traders will receive full financial compensation for their losses. Official statements guaranteed complete repayment without specifying an exact timeline or claim submission criteria. Traders continue awaiting operational guidelines from the exchange. Balance sheet impacts remain contained for now.
International platform users regained standard deposit and withdrawal access Tuesday afternoon. Order matching returned to normal speeds across major prediction contracts. Security teams continue monitoring blockchain networks for asset laundering activity. Affected account holders await further instructions on claim verification.
