SlowMist stated ZetaChain has been exploited. Preliminary analysis indicates the root cause of the vulnerability lies in the lack of access control and input validation in the call function of the GatewayZEVM contract.

The relevant attack transactions have been disclosed.
Simon Dedic, founder of Moonrock Capital, posted on X: “It's quite interesting how people get furious about 'insiders' on Polymarket, completely ignoring the fact that prediction markets simply cannot function without them.

Remove them, and you won't get a fairer market; you'll get a completely useless one.”
