Global Collaboration in Action
Since its inception, T3 FCU has supported law enforcement agencies across 23 jurisdictions, assisting in cases involving money laundering, fraud, hacks, terrorism financing, and organized crime. A notable example is its work with the Brazilian Federal Police in Operation Lusocoin, which targeted large-scale money laundering and currency evasion through crypto. The operation resulted in the freezing of over R$3 billion in assets, including 4.3 million USDT linked to the criminal group, demonstrating the effectiveness of combining blockchain analytics with law enforcement expertise.
The largest volumes of assistance were recorded in the United States, Spain, Germany, Albania, Brazil, Australia, Poland, and the United Kingdom. Common investigations included illicit goods and services, scams, and crimes linked to banned substances. The unit has also observed a rise in "wrench attacks," incidents of violent coercion connected to crypto, underlining the need for timely international intervention.

Paolo Ardoino, Tether CEO, emphasized that stablecoins can be a force for transparency when combined with rigorous monitoring and collaboration with over 280 law enforcement agencies worldwide. Justin Sun, Founder of TRON, noted that the $300 million milestone proves progress occurs when cross-sector partnerships operate in sync. TRM Labs’ Esteban Castaño added that no single entity can combat financial crime alone, highlighting the importance of a shared, real-time approach to investigations.
