In response to the attack, Polyhedra Network said that after investigation, the incident had nothing to do with the security of Polyhedra Network's bridge. Its bridge has been audited by multiple auditing companies and is currently operating normally, and users do not have any asset security issues. This incident was a man-made theft and was not caused by a contract loophole, and the relevant personnel will be held legally responsible.
According to Paidun monitoring, the attack was caused by a key leak.
