Incident Overview
Blockaid warned that users who have previously connected their wallets to CoW Swap should immediately revoke any related contract approvals via their wallets or security tools, and refrain from interacting with cow.fi until the issue is resolved to prevent potential asset loss. Subsequently, CoW DAO issued a statement confirming that the CoW Swap front end (swap.cow.fi) is currently experiencing issues. The team is actively investigating and advised users to temporarily avoid using the platform for trading. On April 16, it was reported that CoW Swap announced on X (formerly Twitter) that it has regained control of the cow.fi domain and has been operating normally on cow.finance for some time. The platform is now gradually transitioning back to its original domain.
