T3 Unit’s Global Footprint Expands
Since launching in September 2024, the T3 Financial Crime Unit (T3 FCU) has become one of the most proactive forces in combating financial crime in the blockchain ecosystem. It operates with the goal of cleaning up stablecoin activity, especially on the TRON blockchain where most Tether transactions happen.
Some of the unit’s most notable achievements include:
- Operation Lusocoin in Brazil, where authorities froze over R$3 billion in assets, including 4.3 million USDT linked to a sophisticated money laundering ring. The unit was formally recognized by the Brazilian Federal Police for its support.
- Collaboration with U.S. authorities that resulted in $83 million in frozen assets across 37 cases, making the U.S. the most active jurisdiction so far.
- Seizures tied to North Korean-linked hacks, including a $19 million asset block from the Bybit hack.
- Real-time coordination with major exchanges, like Binance, via the T3+ Global Collaborator Program launched in August 2025, which already led to an additional $6 million in scam-related asset freezes.
Crimes and Trends Being Tracked
The crimes targeted by the unit paint a disturbing picture of the evolving threats in crypto finance:
- Illicit goods and services top the list, making up 39 percent of cases.
- Fraud and scams, often involving “pig butchering” romance cons, remain a persistent issue.
- Hacks and exploits, increasingly sophisticated and sometimes state-sponsored, continue to pose global risks.
- A worrying rise in “wrench attacks” physical coercion involving crypto holders highlights the urgent need for rapid intervention and better security.
Industry and Law Enforcement Working Hand in Hand
The success of the T3 initiative is largely due to its close coordination with over 280 law enforcement agencies around the world. Its backers believe that such collaborations are essential to making crypto ecosystems safer.

SQ Magazine’s Takeaway
I’m impressed. This is more than just a PR moment. It’s proof that crypto doesn’t have to be lawless. Seeing Tether and its partners step up to clean house shows that with the right tools and cooperation, digital finance can become safer for everyone. Freezing $300 million in a year is no small feat. This unit is not just reacting to crime, it’s reshaping how the industry deals with it. If you ever doubted whether blockchain tech could serve justice, this is your wake-up call.
