Tether, TRON, and TRM Labs Freeze $300M in Criminal Crypto Assets Through T3 FCU

T3 FCU, a joint initiative from Tether, TRON, and TRM Labs, has frozen more than $300 million in criminal assets worldwide, accoridng to a recent report. The unit, formed in late 2024, aims to clean up onchain activity by targeting scams, hacks, and money-laundering networks operating through stablecoins — primarily USDT on the TRON blockchain.

In its first year, the T3 Financial Crime Unit (FCU) has become a model for blockchain security enforcement. It has collaborated with over 280 law enforcement agencies globally, supporting major investigations across five continents.

From Stablecoin Oversight to Global Enforcement

Initially, T3 FCU focused on monitoring suspicious activity tied to stablecoin transactions on TRON, which has become one of the most used networks for USDT transfers. Over time, the initiative grew into a global enforcement model that supports investigations into organized crime, cyber theft, and scams.

“Tether is deeply committed to maintaining the integrity of the financial ecosystem by collaborating with over 280 law enforcement agencies globally,” Tether CEO Paolo Ardoino, said.

By January 2025, T3 had already frozen $100 million in illicit USDT, including $3 million linked to North Korean networks. By August, the total had surpassed $250 million, supported by the launch of the T3+ Global Collaborator Program, a new framework designed to deepen industry–law enforcement cooperation.

Expanding Global Collaboration

The T3+ Global Collaborator Program

The T3+ Global Collaborator Program, launched in August 2025, is the latest phase of the initiative. It brings exchanges, blockchain projects, and law enforcement into real-time coordination.

Binance was the first exchange to join, helping authorities freeze $6 million linked to a pig-butchering scam. 

The program was also presented at Vienna’s 9th Global Conference on Criminal Finances and Cryptocurrencies, co-hosted by Europol and the Basel Institute on Governance. Executives from TRON DAO, Tether, TRM Labs, and Binance met with Europol officials to explore how the T3 framework could guide future public-private partnerships in crypto crime prevention.

Tracking Criminal Networks Across Continents

The T3 FCU has become central to several high-profile cases:

• Operation Lusocoin (Brazil): Supported by T3, this investigation led to the freezing of R$3 billion (roughly $600 million) in criminal assets, including 4.3 million USDT connected to an organized crime group.
• Pig-butchering scams: T3 tracked and froze millions in USDT tied to romance and investment frauds operating in Asia and Europe.
• North Korean-linked cybercrime: The unit intercepted $3 million connected to the Lazarus Group, a North Korean hacking syndicate responsible for multiple global crypto thefts.

Despite these successes, some criminal funds continue to slip through. In February 2025, the Lazarus Group carried out a $1.5 billion hack on Bybit, laundering roughly $1 billion by midyear. The incident remains the largest successful crypto hack to date, highlighting that even with improved surveillance, enforcement remains an ongoing challenge.

Mapping Global Enforcement: Key Jurisdictions

T3’s efforts span 23 regions, with the United States ranked as the most active jurisdiction, recording $83 million frozen across 37 cases. Other key enforcement areas include Europe and South America, where local agencies have increased their reliance on blockchain analytics tools developed by TRM Labs.

According to internal reports:

• 39% of T3’s workload involves the illegal sale of goods and services.
• The rest covers fraud, terrorism financing, extortion, and money laundering cases.
• Individual seizures, such as the $19 million confiscation tied to the Bybit hack, show how the task force coordinates with global police agencies in real time.

A Closer Look at the T3 Financial Crime Unit

The T3 FCU operates as a multi-party enforcement and monitoring body. Each partner contributes a unique capability:

• Tether: Provides transaction-level visibility across USDT activity and executes asset freezes when funds are flagged.
• TRON: Supplies the blockchain infrastructure and coordinates network-level compliance signals.
• TRM Labs: Delivers the analytics, investigation tools, and blockchain intelligence used to identify illicit activity.

Together, these organizations have built a real-time enforcement loop where suspicious transactions are flagged, verified, and acted upon in collaboration with law enforcement agencies.

The FCU’s tools enable the freezing of stablecoins at the contract level, allowing immediate disruption of laundering routes. This technical capacity gives regulators a clearer view of how illicit funds move — something traditional banking often struggles to achieve.

Challenges Ahead

Despite its progress, T3 faces several hurdles:

• Jurisdictional differences make it difficult to apply uniform enforcement standards globally.
• Privacy concerns remain around how onchain data is shared with authorities.
• Technical limits in tracking assets across multi-chain ecosystems can slow investigations.

Nevertheless, the continued expansion of the T3+ Collaborator Program indicates the industry’s willingness to address these gaps collectively.

Conclusion

The T3 Financial Crime Unit’s $300 million milestone demonstrates that blockchain technology can deliver measurable results in fighting financial crime. Instead of waiting for regulators to dictate terms, Tether, TRON, and TRM Labs have built a framework where enforcement, analytics, and compliance work hand in hand.

The model proves that crypto infrastructure, when paired with responsible oversight, can serve both innovation and accountability.
