Tether has executed a massive wave of asset freezes over the last 30 days, blacklisting 371 addresses and locking approximately $515 million in USDT across the Ethereum and Tron blockchains. According to data from BlockSec’s USDT Freeze Tracker as of May 7, 2026, the enforcement activity was heavily skewed toward the Tron network. Tron accounted for 329 of the blacklisted addresses and nearly $506 million of the frozen capital, while Ethereum saw 42 addresses restricted, totaling roughly $8.73 million in blocked funds.
The surge in blacklisting highlights Tron’s growing role as a primary corridor for stablecoin activity, as the network’s high liquidity and frequent exchange transfers often attract both legitimate and illicit high-value movements. This latest crackdown follows a highly active 2025, during which Tether blacklisted more than 4,100 unique addresses and secured $1.26 billion in USDT. BlockSec’s monitoring tools, which track on-chain freeze and destroy events, suggest that Tether is increasingly aggressive in its efforts to police the stablecoin’s ecosystem.
A significant portion of the recent freezes has been linked to the collapse of the DSJ Exchange and BG Wealth Sharing scheme. On-chain investigator ZachXBT reported that the alleged Ponzi scheme shuttered after defrauding users of more than $150 million. Following a flurry of illicit cross-chain movements totaling $92 million in late April, a collaborative effort between ZachXBT, Tether, Binance Security, OKX, and U.S. law enforcement resulted in the freezing of $38.4 million on May 4. Additional funds were subsequently locked by various exchanges and service providers.
This enforcement wave also coincides with broader geopolitical crackdowns, including “Operation Economic Fury,” a U.S.-led campaign targeting Iranian financial flows. Tether recently froze $344 million in USDT across two Tron addresses linked by authorities to Iran’s IRGC, contributing to total U.S. seizures of Iranian-tied crypto assets approaching the $500 million mark. Tether maintains that these actions are part of its ongoing partnership with over 340 law enforcement agencies globally to curb sanctions evasion and criminal activity.
