According to Odaily Planet Daily, Ethereum Layer2 protocol Loopring recently discovered a security vulnerability in its two-factor authentication (2FA) service, so the automatic smart contract upgrade originally scheduled for June 12 on the Ethereum mainnet has been postponed. Loopring will upgrade later and announce the upgrade date in advance. Despite this security vulnerability, it does not affect the security of smart contracts. Both existing and new smart contracts remain secure.
