Recent data from BlockSec’s $USDT Freeze Tracker revealed that Tether blacklisted hundreds of wallet addresses and froze approximately $515 million in $USDT over the last 30 days, with Tron accounting for the majority of activity.

Investigators linked part of the frozen funds to suspected fraudulent schemes, while coordinated actions reportedly involved exchanges, Tether, and U.S. authorities.

The development reflects the increasing role of compliance monitoring and on-chain enforcement mechanisms within the stablecoin sector.
