Incident Overview
Now the vulnerability has been successfully repaired, and all users' assets are safe and cross-chain. Transactions will not be affected. However, if the user has authorized these six assets, he needs to log in as soon as possible to revoke the authorization, otherwise the assets may be at risk. According to the official announcement on the 19th, because some users did not cancel the authorization in time, the stolen funds were about 445 WETH, worth about 1.43 million US dollars.
