Polymarket's third-party service provider was hacked this morning, with trading suspended for about an hour.

BlockBeats news, October 30, according to the Polymarket status page, at 2:05 AM Beijing time on October 30, the platform entered cancel-only mode and suspended relay operations. About an hour later, Polymarket stated it had identified and fixed the issue on the international site, saying a third-party service provider was compromised, the incident has been referred to law enforcement, and affected users will receive full compensation. Trading subsequently resumed, and the status page marked the incident as resolved.

According to Bubblemaps monitoring, over 700 users were affected in this theft incident, with approximately $2.7 million in funds stolen. This is already Polymarket's third security incident this year: in May, an internal operations wallet of Polymarket was stolen due to a private key from six years ago, resulting in a loss of about $700,000; on June 25, a third-party vendor was compromised, leading to the injection of malicious scripts into the frontend, and approximately $3 million in user funds were stolen, affecting fewer than 15 accounts, with the platform promising full compensation.

There is currently no evidence indicating that this incident is related to the Binance incident.
