Tether Freezes $5.2M in USDT from 12 Suspicious Addresses

As an experienced financial analyst following the cryptocurrency industry, I have observed with great interest Tether’s proactive stance against money laundering and other illegal activities involving its USDT stablecoin. The recent freezing of $5.2 million worth of USDT in 12 suspect addresses by blockchain security platforms is yet another testament to the company’s unwavering commitment to upholding regulatory compliance.


Tether, a prominent issuer of stablecoins on a global scale, has taken steps to freeze funds linked to crypto wallets under suspicion for money laundering and other unlawful activities, including violations of government-imposed sanctions. On May 14, MistTrack, a blockchain security firm, disclosed that they had blocked access to $5.2 million worth of USDT stablecoins tied to 12 specific addresses. These addresses have been flagged as “USDT restricted addresses” by MistTrack, signaling potential involvement in illicit activities.

Suspicion of Money Laundering

As a security analyst at a firm, I’ve come across the recommendation from SlowMist, a reputable blockchain security company, suggesting potential links between the frozen addresses and money laundering activities concerning Tether. Yet, Tether has not released an official statement on this matter.

In the previous year, TRM Labs, a business specializing in blockchain investigation for US law enforcement, identified Tether’s USDT as a preferred means for terrorist financing transactions. This revelation led Tether to reinforce their compliance procedures in response.

The stablecoin issuer reaffirmed its dedication to collaborate with international law enforcement in their efforts to prevent terrorism and armed conflicts from being financed through cryptocurrencies.

After that point, Tether has taken proactive measures to prevent suspected fraudulent accounts from utilizing its USDT for illicit activities and circumventing regulatory penalties.

In April, Tether disclosed their plan to prevent certain wallet addresses from accessing their stablecoin, USDT, due to allegations that Venezuela’s national oil company, PDVSA, aimed to employ USDT for evading newly imposed US sanctions on their oil industry.

For more than a year, the Venezuelan company has employed digital assets to carry out its business activities. However, in response to the economic hardships brought about by the sanctions, the firm intends to expand its utilization of these assets.

A representative from Tether explained that their action to prohibit transactions involving USDT for purchasing oil from PDVSA aligns with their dedication to thwarting payments connected to OFAC-sanctioned entities.

Past Actions Against Illicit Activity

In the past, Tether has blacklisted several crypto wallets linked to illicit activities.

In the previous year, the firm seized 32 digital wallets holding a total of $873,118.34 due to their involvement in unlawful activities in Israel and Ukraine. This action was initiated following Israeli authorities’ freezing of cryptocurrency accounts employed for Hamas fundraising on social media after the tragic October 7 attack that claimed over 1,300 lives.

In that very year, the corporation blocked access to 160 cryptocurrency wallets identified as being connected to individuals or entities on the Office of Foreign Assets Control (OFAC) sanctions list. Among these wallets, a limited number contained approximately $3.9 million worth of USDT stablecoin.

In the second half of 2022, I came across an unexpected situation where over $1 million worth of USDT and other cryptocurrencies in an Ethereum address I held got frozen by Tether. This was the largest seizure from a single address reported so far. However, it’s important to note that apart from freezing addresses, Tether has been proactive in helping recover funds lost due to hacking incidents exploiting vulnerabilities in the crypto market for personal gain.
