Hacken claims that the Tron network's $91.3 billion USDT is controlled by 2-of-3 multi signature, posing a risk of contract authority being taken over

Blockchain security company Hacken pointed out that the USDT worth $91.3 billion on the Tron network is controlled by 2-of-3 multi signature contracts, and holders of two signature keys can take over contract management privileges, and the contracts lack mechanisms for delay, cancellation, or revocation. Attackers can change the contract owner to mint USDT, freeze addresses, destroy balances, or charge transfer fees. The multi signature wallet controls the USDT contract itself, rather than directly holding user funds.
