Ethereum Layer 2 protocol Loopring has released a security update for Loopring Smart Wallet on the X platform, saying that the "Loopring Official Guardian Service" has returned to normal, and now users can access services related to two-factor authentication (2FA) again through the wallet. To enhance security, all approvals by Loopring Official Guardian will not take effect immediately. After passing 2FA verification, requests will only take effect after passing additional internal security checks.
