Tether froze approximately $515 million worth of USDT across the Ethereum and Tron networks over the past 30 days, according to data from BlockSec’s USDT Freeze Tracker.
Summary
Tether blacklisted 371 wallet addresses across Ethereum and Tron, freezing nearly $515 million in USDT.
Tron accounted for the majority of enforcement activity, with 329 frozen addresses and roughly $506 million in blocked USDT.
Blockchain investigator ZachXBT linked $38.4 million in frozen USDT to the collapsed DSJ Exchange and BG Wealth Sharing scheme.
According to BlockSec’s tracking data, 371 wallet addresses had been blacklisted as of May 7, 2026. Of those, 329 were on the Tron network, while 42 were on Ethereum.
The overwhelming majority of the frozen assets were tied to Tron-based wallets. Approximately $506 million in USDT was frozen on Tron, compared with around $8.73 million on Ethereum. BlockSec said its monitoring system tracks USDT freeze, unfreeze, and token destruction events using on-chain data from both blockchains.
Tron dominates the latest blacklist activity
The latest enforcement wave highlights Tron’s growing role in stablecoin activity. The network currently hosts a substantial share of the global USDT supply, making it one of the most frequently used chains for transfers, exchange deposits, and high-value transactions.
Earlier reports from BlockSec showed that during 2025, Tether blacklisted 4,163 unique wallet addresses across Ethereum and Tron. Those actions reportedly froze about $1.26 billion in USDT over the course of the year.
DSJ and BG Wealth case draws attention
The recent blacklist activity also coincided with investigations into the collapse of DSJ Exchange and BG Wealth Sharing. Blockchain investigator ZachXBT said the alleged Ponzi-style scheme collapsed after reportedly collecting more than $150 million from users before disabling withdrawals.
According to ZachXBT, illicit actors moved over $92 million across multiple blockchain networks between April 27 and May 3. He stated that he coordinated efforts with Tether, Binance Security, OKX, and U.S. law enforcement agencies. The operation reportedly resulted in $38.4 million in USDT being frozen by Tether on May 4, alongside additional freezes carried out by exchanges and other services.
USDT freezes expand under global enforcement efforts
The latest action follows a broader crackdown involving crypto-related sanctions enforcement. Earlier, Tether froze $344 million in USDT connected to two Tron wallet addresses after U.S. authorities linked them to Iran’s Islamic Revolutionary Guard Corps under Operation Economic Fury.
Subsequent reports indicated that total U.S. seizures related to Iranian crypto-linked assets had approached $500 million, exceeding the original $344 million freeze publicly confirmed by Tether.
Tether has previously stated that it works alongside more than 340 law enforcement agencies across 65 countries. In an April statement, the company said it reserves the ability to freeze or restrict assets tied to sanctions evasion, organized crime, or other illegal activities.
