ZetaChain halts cross-chain transactions after GatewayEVM contract attack, no user funds lost

ZetaChain paused all cross-chain transactions on its mainnet after detecting an attack on its GatewayEVM smart contract, which routes interactions between connected blockchain networks. The attack affected only internal team wallets, with no user funds compromised, and the team has closed the attack path. DefiLlama reported losses of about $300,000, but ZetaChain is preparing a detailed post-mortem and continues investigating. This incident highlights ongoing security challenges in DeFi and blockchain interoperability projects.
