The Ethereum Layer2 protocol Loopring posted on social media that due to a security vulnerability in Loopring's two-factor authentication (2FA) service, the scheduled automatic upgrade of the smart contract on the Ethereum mainnet on June 12 has been postponed. The upgrade will be carried out later, and the upgrade date will be announced in advance. Please note that this security vulnerability will not affect the security of our smart contracts. Existing and new smart contracts remain secure.
