Incident Overview
Blockchain security firm Defimon Alerts identified that the attack vector exploited a gateway verification bypass vulnerability in CrossCurve’s ReceiverAxelar contract. Analysis shows that anyone could use a forged cross-chain message to call the contract’s expressExecute function, thereby bypassing the intended gateway verification and triggering unauthorized token unlocks on the protocol’s PortalV2 contract. Subsequently, CrossCurve issued a security update regarding the $EYWA token, stating that the exploitation has been successfully contained.
