Tether, the issuer of the USDT stablecoin, has frozen approximately $182 million in USDT across five wallets on the Tron blockchain. This occurred on January 11, 2026, in what appears to be one of its largest single-day enforcement actions recently.
The affected wallets held balances ranging from roughly $12 million to $50 million each. Blockchain monitoring service Whale Alert flagged the freezes in real time, showing the addresses being blacklisted via Tether’s admin controls on the Tron network where a significant portion of USDT circulates—over $80 billion.
Tether confirmed the action was in response to a formal request from U.S. law enforcement likely involving agencies like the DOJ or FBI as part of an ongoing investigation. While specific details of the probe remain undisclosed, such freezes typically target suspected illicit activities, including money laundering, scams, sanctions evasion, or other criminal use of crypto.

Some reports speculate links to efforts bypassing U.S. sanctions in contexts like Venezuelan oil transactions or similar patterns seen with Iran but this is not officially confirmed. This aligns with Tether’s formal wallet-freezing policy introduced in late 2023, which allows blacklisting addresses to comply with regulations like the U.S. Treasury’s OFAC sanctions list.
Since 2023, Tether has frozen over $3.3 billion in USDT across thousands of addresses around 7,268 wallets blacklisted, per analytics firm AMLBot, with a substantial portion on Tron about $1.75 billion. This far exceeds competitors like Circle’s USDC, which has frozen around $109 million in the same period—highlighting Tether’s dominant market position— USDT holds ~60-64% of the stablecoin market, with total circulation over $180-187 billion.
The event underscores the centralized nature of stablecoins like USDT: issuers maintain admin keys to freeze tokens, enabling quick compliance but raising debates about censorship resistance and user control in crypto.
No immediate major market disruption was reported from this freeze, though it contributes to broader discussions on stablecoin oversight and regulatory tightening in 2026. Tether emphasizes these actions target only high-risk or illicit funds and do not impact ordinary users.
Tether’s freezing policy for USDT, its USD-pegged stablecoin allows the company to blacklist or freeze specific wallet addresses, rendering the USDT held in those addresses unable to be transferred, spent, or redeemed. This is a centralized control mechanism built into the smart contracts on supported blockchains especially prominent on Tron, where much USDT volume occurs.
Tether formalized a voluntary wallet-freezing framework in December 2023. This was primarily to comply with U.S. Treasury’s Office of Foreign Assets Control (OFAC) sanctions requirements, including automatically freezing wallets on the Specially Designated Nationals (SDN) list.
According to Tether’s terms available on their legal page, under sections like law enforcement requests, the company reserves the right to: Freeze addresses or share user information when ordered to do so by authorities e.g., court orders, law enforcement requests from agencies like the DOJ, FBI, Secret Service, IRS-CI, or international equivalents.
Do so voluntarily “if this appears reasonable and necessary” to Tether, such as in cases of suspected illicit activity, fraud, money laundering, terrorism financing, sanctions evasion, or other high-risk behaviors. Tether uses admin/privileged functions in the USDT smart contracts to add addresses to a blacklist. Once blacklisted:The tokens remain visible on-chain and part of the total supply.
Transfers from or to the address are blocked. Redemption for fiat is prevented. This applies across chains but has been most active on Tron due to its dominance in USDT circulation. Tether has emphasized that freezes target only high-risk or illicit funds and do not affect ordinary users. Key stats from recent reports and Tether announcements as of mid-2025 to early 2026: Over $3 billion some sources cite up to $3.3 billion in USDT frozen since 2023.
Thousands of wallets blacklisted around 7,268 per AMLBot analytics, with over 5,000–7,000 total reported in various updates. Collaboration with hundreds of law enforcement agencies e.g., over 310 agencies across 62 jurisdictions, including more than 2,750–2,800 coordinated with U.S. agencies alone.
This far outpaces competitors like Circle’s USDC around $109 million frozen in the same period, reflecting USDT’s larger market share ~60–65% of stablecoins. Examples of use cases include: Freezes tied to terrorism financing e.g., Gaza-based networks.
Sanctions violations like those in Russian exchange Garantex, or broader evasion efforts.Scams (pig butchering, tech support). Money laundering and drug trafficking investigations. Tether often reissues equivalent clean USDT to authorities after freezes in forfeiture cases, aiding recovery.
This policy highlights the centralized nature of fiat-pegged stablecoins like USDT—unlike truly decentralized assets, issuers hold keys/controls for compliance. Tether positions it as essential for fighting crime and maintaining regulatory goodwill, especially amid increasing scrutiny in 2025–2026.
Critics argue it undermines crypto’s censorship resistance and user sovereignty. The policy evolves with regulations, but the dual mandatory/voluntary approach has remained consistent since late 2023.
