HashKey Chain administrator temporarily replaced contract transfer 142,818 USDT

According to The Defiant, the HashKey Chain administrator transferred 142,818 USDT by temporarily replacing the contract, and about six minutes later, the original deposit code was restored. HashKey Chain is an Ethereum Layer 2 network launched by HashKey Group, primarily aimed at compliance and institutional-level application scenarios.

The report shows that this temporary replacement did not change the final state of the deposit code, but a multi-signature composed of five members, requiring three signatures, still retains the immediate upgrade authority, allowing upgrades to the contract to be executed without a time lock delay.
