Polymarket executive: Private key rotation has been completed, and all private keys are planned to be migrated to KMS in the future.

According to Odaily Planet Daily, Josh, VP of Engineering and DeFi at prediction market Polymarket, stated in an article on the X platform that the security incident stemmed from the leakage of a 6-year-old private key. This private key was used for internal top-up configuration, which explains why some funds were sent to that address. Josh added that the Polymarket team has completed private key rotation, revoked all production environment permissions, and plans to migrate all private keys to a Key Management Service (KMS) instead of continuing to store them in the traditional way. Furthermore, Polymarket and its UMA contracts were not compromised, all user funds are safe, and the platform is functioning normally.
