Tether has frozen approximately $515 million worth of USDT across the TRON and Ethereum networks over the past 30 days, according to BlockSec’s USDT Freeze Tracker. The enforcement action blacklisted a total of 371 wallet addresses — 329 on Tron and 42 on Ethereum — as of May 7, 2026. Roughly $506 million of the frozen funds were on Tron, with the remaining $8.73 million on Ethereum, highlighting the growing concentration of stablecoin enforcement activity on the Tron network due to its high USDT supply and transaction volume.
The wave of freezes gained additional context as on-chain investigator ZachXBT linked $38.4 million of the blocked USDT to the collapsed DSJ Exchange and BG Wealth Sharing scheme. The alleged Ponzi scheme reportedly took over $150 million from users before disabling withdrawals. ZachXBT said illicit actors moved more than $92 million across chains between April 27 and May 3, and he collaborated with Tether, Binance Security, OKX, and U.S. law enforcement to trace and freeze assets. The coordinated effort led to the $38.4 million freeze on May 4, with additional funds blocked by exchanges and service providers.
This latest enforcement push follows a prior high-profile freeze of $344 million in USDT on two Tron addresses linked to Iran’s Islamic Revolutionary Guard Corps (IRGC) as part of Operation Economic Fury. Tether has stated it works with more than 340 law enforcement agencies across 65 countries and can restrict assets tied to sanctions evasion, criminal networks, or other unlawful activity. BlockSec’s earlier data showed that in 2025, Tether blacklisted 4,163 unique addresses and locked $1.26 billion in USDT, underscoring a clear trend of intensified compliance measures.
