Tether froze about $515 million in USDT across Ethereum and Tron over the past 30 days, according to BlockSec’s USDT Freeze Tracker.
Summary
- Tether blacklisted 371 Ethereum and Tron addresses, freezing about $515 million in USDT over 30 days.
- Tron accounted for most freezes, with 329 addresses and around $506 million in blocked USDT.
- ZachXBT linked $38.4 million in frozen USDT to the collapsed DSJ and BG Wealth scheme.
The data showed 371 blacklisted addresses as of May 7, 2026, with 329 on Tron and 42 on Ethereum.
The freeze activity was heavily concentrated on Tron. Around $506 million was frozen on Tron, while Ethereum accounted for about $8.73 million. BlockSec says its tracker monitors USDT freeze, unfreeze, and destroy events on Ethereum and Tron using on-chain sources.
Tron leads the latest blacklist wave
The latest figures show how much stablecoin enforcement activity now runs through Tron. The network holds a large share of USDT supply, which makes it a frequent chain for transfers, exchange deposits, and high-value wallet movements.
BlockSec’s earlier 2025 report said Tether blacklisted 4,163 unique Ethereum and Tron addresses last year. It said those freezes locked $1.26 billion in USDT, with Tron and Ethereum covering the main areas of USDT activity.
DSJ and BG case adds fresh context
The freeze data comes as on-chain investigator ZachXBT reported action tied to the DSJ Exchange and BG Wealth Sharing case. He said the alleged Ponzi scheme collapsed after taking more than $150 million from users and disabling withdrawals.
ZachXBT said illicit actors moved more than $92 million across chains between April 27 and May 3. He said he worked with Tether, Binance Security, OKX, and U.S. law enforcement. The effort led to “$38.4M frozen by Tether” on May 4, with more funds frozen by exchanges and services.
Wider enforcement wave puts USDT freezes in focus
As previously reported, Tether froze $344 million in USDT across two Tron addresses after U.S. authorities linked the wallets to Iran’s IRGC. The freeze formed part of Operation Economic Fury, a U.S. campaign targeting Iran-linked crypto flows.
A later crypto.news report said U.S. seizures tied to Iranian crypto assets had neared $500 million. That figure was higher than the earlier $344 million USDT freeze confirmed by Tether.
Tether has also said it works with more than 340 law enforcement agencies across 65 countries. In an April statement, the company said it can restrict assets when wallets are linked to sanctions evasion, criminal networks, or other unlawful activity.
