Regarding the hacking incident, the officials from Polyhedra Network have confirmed through investigation on their Discord channel that the incident is unrelated to the security of Polyhedra zkBridge. The incident was caused by deliberate theft rather than any vulnerabilities in the contract itself. Polyhedra will take legal action against the individuals involved. The officials emphasize that their cross-chain bridge is secure and user funds are safe. This is a case of theft rather than a technical flaw.
