According to data from the BlockSec USDT Freeze Tracker, as of May 7, 2026, stablecoin issuer Tether has reportedly added 371 wallet addresses to its blacklist over the past 30 days. The action involved freezing approximately US$515 million worth of USDT, equivalent to around Rp8.94 trillion.

Most of the blocked addresses originated from the Tron network, accounting for 329 addresses with roughly US$506 million in frozen funds. Meanwhile, on the Ethereum network, 42 addresses were blacklisted with a total of around US$8.73 million frozen.

The move once again highlights increasing scrutiny over stablecoin transaction activities, particularly those linked to suspected money laundering, fraud, exploits, and illegal cross-chain operations.

Majority of Funds Frozen on the Tron Network

According to BlockSec data, more than 98% of the frozen assets originated from the Tron blockchain. This indicates that the network remains one of the primary channels for large-scale USDT transfers, especially for cross-border transactions and OTC (over-the-counter) activities.

In detail:

• 329 Tron addresses were frozen
• Total blocked funds reached approximately US$506 million or Rp8.78 trillion
• 42 Ethereum addresses were frozen
• Total blocked funds reached around US$8.73 million or Rp151.5 billion

Tether has the capability to freeze USDT directly at the smart contract level. This feature is typically used when the company receives requests from law enforcement authorities, findings from on-chain investigations, or reports of suspicious activity.

In recent years, Tether has become increasingly active in cooperating with global law enforcement agencies to monitor crypto fund flows associated with illegal activities.

Alleged Links to Illegal Activities and Stablecoin Oversight

Although Tether has not disclosed the identities of the owners behind the blocked addresses, on-chain analysts believe the large-scale freezes are likely related to investigations involving money laundering networks, investment scams, and crypto platform exploits.

According to blockchain security analysts, Tron frequently attracts regulatory attention due to its low transaction fees and fast transfer speeds, making it widely used for large stablecoin transfers.

In addition, the trend of mass blacklisting shows that stablecoin issuers are increasingly playing roles similar to traditional financial institutions, particularly in terms of compliance and transaction monitoring.

Based on on-chain data, Tether has previously frozen assets linked to major hacking incidents, DeFi exploits, and illegal financing activities.

Impact on the Stablecoin Ecosystem

Although the address freezes do not directly affect USDT’s market price, the move reinforces the narrative that centralized stablecoins can be controlled by their issuers.

For some industry participants, the ability to freeze assets is considered important for supporting ecosystem security and regulatory compliance. However, parts of the crypto community also view it as evidence of the high level of centralization within stablecoins such as USDT.

Amid growing global regulatory scrutiny toward stablecoins, Tether’s actions are expected to strengthen calls for stricter compliance standards, particularly for cross-chain transactions and institutional activities.

As context, USDT remains the largest stablecoin in the crypto market, with a market capitalization exceeding US$100 billion and daily transaction volumes dominating global digital asset trading.

Conclusion

The freezing of approximately US$515 million in USDT over the past 30 days reflects the increasing intensity of oversight on fund flows within the crypto industry. With most cases concentrated on the Tron network, the data also demonstrates how low-cost blockchains continue to serve as central hubs for global stablecoin activity.

At the same time, Tether’s actions underline the growing strategic role of stablecoin issuers in supporting investigations and regulatory compliance, while also reigniting debates over centralization within the digital asset ecosystem.
