CoW Swap, an Ethereum-based decentralized change aggregator, warned customers on Tuesday to keep away from utilizing the protocol, disclosing that its front-end interface had been compromised.
“We at the moment are actively working to resolve the scenario,” the challenge steadily utilized by Ethereum co-founder Vitalik Buterin stated in a publish to X. “The CoW Protocol backend and APIs weren’t impacted, however we now have paused them quickly as a precaution.”
CoW Swap indicated that attackers had gained management of the web site area that customers usually go to earlier than participating with the protocol.
