According to a report by BlockBeats, the compliance company AMLBot shows that Tether's wallet blacklist mechanism has significant delays, allowing over $78 million in illegal funds to be successfully transferred before the freeze took effect.
The report indicates that Tether's multi-signature contract setup on the Ethereum and Tron blockchains results in an average delay of 44 minutes from submission to activation of the blacklist. On the Ethereum chain, approximately 28.5 million USDT were transferred during the blacklist delay, with an average transfer exceeding $365,000.
On the Tron chain, $49.6 million was transferred to evade the freeze, with about 4.88% of the flagged wallets exploiting this loophole to carry out 2-3 transfers, averaging $292,000 per wallet.
