According to a report by BlockBeats, the blockchain compliance company AMLBot shows that Tether's wallet blacklisting mechanism has significant delays, allowing over $78 million in illegal funds to be successfully transferred before the freezing took effect.
The report indicates that Tether's multi-signature contract setup on the Ethereum and Tron blockchains causes an average delay of 44 minutes from submission to the blacklisting taking effect. During the blacklisting delay on the Ethereum chain, approximately 28.5 million USDT were transferred, averaging over $365,000 per transfer.
On the Tron chain, there is $49.6 million that evaded freezing, with approximately 4.88% of the flagged wallets taking advantage of this loophole to conduct 2-3 transfers, averaging $292,000 per wallet.
