[Unverified Contract on Base Attacked, User Loses 55 WETH] CertiK Alert monitoring indicates that an unverified contract on Base was attacked, causing a user who had previously authorized the contract to lose 55 WETH (approximately $220,000). Users are advised to revoke authorization for the address 0xE143b486ab0413Df0D6DAd2caf6d2f61CAC54730.
