According to Odaily, the Ethereum Layer2 protocol, Loopring, has announced a delay in its scheduled automatic upgrade on the Ethereum mainnet. The upgrade, originally set for June 12, has been postponed due to a recent security flaw in Loopring's two-factor authentication (2FA) service. The upgrade will be carried out at a later date, which will be announced in advance.
Despite the security flaw, it is important to note that the safety of our smart contracts is not compromised. Both existing and new smart contracts remain secure. The security flaw in the 2FA service does not affect the security of the smart contracts. The team behind Loopring is working diligently to address the issue and ensure the smooth implementation of the upgrade when it is rescheduled.
