Zetachain Pauses Mainnet Following GatewayZEVM Contract Exploit
- Zetachain halted cross-chain transactions after an exploit impacted internal team wallets, valued at approximately $300k.
- The vulnerability was traced to the GatewayZEVM contract’s call function, which lacked access control and input validation.
- This incident is the second major cross-chain exploit in April, following the KelpDAO hack that caused significant liquidity issues in DeFi protocols.
- The Arbitrum Security Council intervened by freezing over 30,766 ETH linked to the KelpDAO exploiter.
Zetachain’s security breach highlights ongoing vulnerabilities in cross-chain infrastructure due to insufficient access controls in smart contracts. The protocol has paused operations to assess the breach’s full impact while ensuring user funds remain secure.
The recurring pattern of missing access controls underscores a critical area for improvement in smart contract security, as evidenced by recent exploits affecting Zetachain and KelpDAO. (Source)
