ChainCatcher reports that according to the blockchain compliance company AMLBot, since 2017, Tether has experienced delays in blacklisting suspicious addresses, resulting in over $78 million in USDT being transferred before freezing could take effect.
The delay stems from Tether's multi-signature contract mechanism on Ethereum and TRON, where the blacklisting process requires two multi-signature transaction confirmations, with an average time gap of 44 minutes. During this window, attackers can monitor blacklist submission transactions in real-time and quickly transfer assets, thus avoiding freezing measures.
The report indicates that approximately 170 TRON addresses exploited this delay, with an average of nearly $290,000 transferred per address before being officially blacklisted. This incident has raised questions about Tether's compliance execution efficiency.
