ZetaChain disclosed in a post on X that its GatewayEVM contract was attacked today, affecting only wallets belonging to the internal ZetaChain team. The attack vector has been blocked to prevent further loss of funds. As a precautionary measure, cross-chain transactions on ZetaChain are currently suspended. The investigation is still ongoing, and no user funds have been affected so far. On April 29, ZetaChain announced on X that on April 27 it had suffered a premeditated and targeted attack. The attacker funded addresses using Tornado Cash and impersonated wallet addresses. Cross-chain ZETA transfers were not affected, and user funds remained safe. All impacted wallets were controlled by ZetaChain. A mainnet patch has been deployed, and cross-chain transactions will be re-enabled after continued monitoring. The attack impacted the arbitrary call functionality of GatewayEVM, resulting in an estimated loss of approximately $334,000 across four connected chains.
