Tether has frozen over $5 Billion in USDT: here’s how

Since November 2017, Tether has frozen USDT stablecoins on 9,856 crypto addresses. The total value of frozen funds has surpassed $5.17 billion. Only around $602 million — roughly 11.6% of the total — has ever been unfrozen. The remaining $4.57 billion is still locked. GetBlock AML Research examined how Tether’s freezing system works and what happens to funds after they are blocked.

The Scale of Freezes Is Far Bigger Than Most Realized

Tether’s wallet-freezing system has been operating for nearly eight years. During that time, the company froze funds on almost 10,000 addresses, but only 744 were later unlocked. In other words, just 7.5% of affected wallets ever regained access.

The numbers become even more striking when looking at the value involved. Out of more than $5 billion frozen, only $602 million has been released. The remaining funds appear to be locked indefinitely. The amount still frozen exceeds the foreign currency reserves of some countries.

Most frozen funds are located on the TRON network. TRON accounts for roughly 70% of all blocked addresses and about 62% of all frozen USDT — around 6,945 wallets holding more than $3 billion.

USDT primarily exists on just two blockchains: Ethereum and TRON. Together, they represent more than 97% of the token’s circulating supply.

TRON became especially popular because of its low fees and fast transfers. It is widely used for international payments, OTC trading, and transactions in regions with weaker financial oversight. However, those same characteristics have also drawn increased attention from regulators and anti-money laundering authorities.

“Pig butchering” scams rely on Tron thanks to near-zero fees and transaction speeds of about 3 seconds. This allows criminals to move stolen funds through dozens of wallets before the victim even realizes the money is gone

Two Very Different Types of Freezes

The data shows that Tether’s freezes tend to follow two distinct patterns.

The largest freeze by wallet count occurred on July 12, 2025, when 796 addresses were blocked. Yet the total value involved was only about $1.99 million.

Shortly afterward, reports linked the action to a terrorism financing investigation. According to U.S. authorities, the funds may have been connected to a network tied to Gaza. The total amount under investigation was approximately $2 million.

The largest freeze by value looked entirely different. On April 23, 2026, Tether froze just 18 wallets — but the total reached nearly $349 million.

That same day, the company announced cooperation with U.S. authorities in a major operation involving the freezing of $344 million in USDT.

The contrast between these cases highlights an important pattern. In 2025, the freeze involved a large number of small wallets averaging roughly $2,500 each, suggesting a fragmented network of smaller transactions.

In 2026, the picture was the opposite: each wallet held nearly $19.4 million on average. Amounts of that size are typically associated with exchanges, large intermediaries, or OTC trading operations.

Ethereum Wallets Recover Funds More Often Than TRON Users

The unfreezing data reveals another major trend. Since June 2018, Tether has restored access to 744 wallets holding a combined $602 million. But the gap between Ethereum and TRON is significant.

On TRON, 456 wallets were unfrozen — more than 61% of all restored addresses. However, the total value returned was only around $141 million.

Ethereum showed the opposite pattern. Only 288 wallets were restored, yet they accounted for more than $461 million returned — over 76% of all unfrozen funds.

This suggests that users on the two networks differ substantially.

TRON is dominated by smaller wallets and lower-value transfers. Owners of those addresses may be less likely to challenge freezes or pursue legal procedures to recover funds.

Ethereum, by contrast, is more commonly used by large companies, exchanges, and professional market participants with the resources and legal teams needed to work with authorities and seek asset recovery.

The Strangest Unfreeze in Tether’s History

On March 24, 2025, Tether carried out an unusual action: the company unfroze 96 addresses in a single day — 95 on Ethereum and one on TRON. It became the largest mass unfreeze by wallet count in Tether’s history.

Notably, the move came shortly after several high-profile investigations involving the company. Tether had assisted the U.S. Secret Service in freezing $23 million connected to a sanctioned Russian crypto exchange. Separately, another $9 million linked to the Bybit hack was blocked.

Yet the total value held across all 96 restored wallets was surprisingly small — just around $34,000. On average, each wallet contained only about $355.

Tether never officially explained the reason for the mass unfreeze. Two possibilities stand out: either the system incorrectly flagged a large number of addresses, or wallet owners successfully challenged the freezes together.

What Happens to Funds That Are Never Released?

The biggest question remains unanswered: what happens to billions of dollars that stay frozen for years?

Technically, frozen USDT remains visible on-chain, but the owner can no longer transfer, exchange, or use it. The funds still exist on the blockchain, yet they are effectively inaccessible.

In 2023, Tether confirmed that freezes are carried out in accordance with U.S. sanctions lists and other regulatory requirements. However, the company has never published a detailed policy explaining the long-term fate of frozen assets.

What is known is that funds are typically unfrozen only after approval from law enforcement agencies or through legal recovery procedures.

Additional data reveals another important detail: some blocked USDT was not merely frozen — it was permanently destroyed.

Since monitoring began, more than $1.32 billion in USDT has been destroyed across 2,105 addresses on Ethereum and TRON. That is nearly three times the number of wallets ever unfrozen and more than double the amount of funds returned to users.

Even when combining destroyed and restored addresses, they still account for less than 29% of all frozen wallets. The fate of the remaining $3.25 billion spread across roughly 7,000 addresses remains publicly unexplained.

Why Information About Freezes Appears So Random

Tether does not publish regular reports covering every freeze. Information usually surfaces only in major cases involving cooperation with U.S. or international law enforcement, fraud investigations, sanctions violations, or the seizure of large amounts.

As a result, the process often appears chaotic: news about freezes emerges irregularly, yet frequently enough to attract attention.

At the same time, the company’s approach has clearly evolved over the past few years. What once looked like isolated and rare enforcement actions increasingly resembled a permanent compliance framework by 2025–2026 — one built around ongoing cooperation with law enforcement agencies and financial regulators.
