Significance of Ethermint in Cosmos
Ethermint is an essential part of the Cosmos ecosystem, enabling Ethereum smart contracts to operate on various chains like Cronos, Kava, and Canto. This cross-chain functionality increases the overall value and attractiveness of the involved platforms.
Uncovering the Vulnerability
If left undiscovered, the bug would have allowed attackers to exploit the weakness and circumvent specific smart contract functions called handlers. This would have facilitated the theft of transaction fees and triggered denial of service for users, considerably affecting the operations of impacted chains.
Joint Efforts to Resolve the Issue
Upon learning of the vulnerability from Jump Crypto, the Evmos Core Development team and the Cronos team united to address the issue. Rapid actions led to the deployment of a patch that blocked transactions containing ‘MsgEthereumTx’ messages, effectively neutralizing the threat.
