Tether has frozen nearly $550 million in USDT associated with Iran-related sanctions networks throughout 2026 as the firm maintains its collaboration with domestic and international regulators. These freezes came in response to law enforcement requests and measures tied to sanctions enforcement.
The restrictions targeted digital wallets that authorities connected to Iran’s financial infrastructure. Additionally, the firm revealed initiatives with Shiga to broaden self-custodial wallet offerings throughout Africa as well as the Gulf Cooperation Council territory.
USDT Addresses Linked to Iran Come Under Restrictions
In April 2026, Tether restricted over $344 million in USDT spanning two distinct addresses following intelligence supplied by the Office of Foreign Assets Control alongside U.S. law enforcement divisions. Afterward, OFAC designated those specific addresses as virtual currency identifiers tied to the Central Bank of Iran.
Later in July 2026, Tether blocked upwards of $130 million in USDT distributed across four extra wallets after U.S. officials broadened sanctions-related listings concerning TRON addresses. These steps elevated the cumulative volume of Iran-associated USDT frozen over the course of 2026 to roughly $550 million.
Tether noted that its assistance with officials spans in excess of 2,900 worldwide inquiries, featuring upwards of 1,600 involving American law enforcement. The enterprise also highlighted cooperation with bodies such as the Department of Justice, the Federal Bureau of Investigation, the U.S. Secret Service, Homeland Security Investigations, and OFAC.
Tether Compliance Partnerships Grow
Tether has additionally collaborated with overseas regulators on matters pertaining to terrorism financing, fraud, and sanctions-related infractions. The organization has worked alongside Israel’s National Bureau for Counter Terror Financing regarding situations involving cryptocurrency addresses implicated in unlawful operations.
Back in 2023, Tether blacklisted 32 addresses holding more than $873,000 in USDT following synchronization with Israeli officials. The corporation subsequently disclosed supplementary blocks exceeding 22 million USDT across upwards of 640 addresses tied to cases directed by that identical bureau.
Tether’s broader cooperative efforts have aided in locking more than $4.9 billion in capital across diverse inquiries. Furthermore, the organization indicated that greater than $2.4 billion of those funds involved investigations linked to American authorities.
Recent instances feature a $225.3 million cryptocurrency forfeiture inquiry backed by Tether, a $61 million fraud-focused freeze, and a $52 million operation involving suspected scam networks.
Crypto Investigations Rely on Blockchain Transaction Records
Tether has aligned its wallet-freezing mechanism with the OFAC Specially Designated Nationals List. This strategy enables the enterprise to block digital wallets flagged under American sanctions directives.
CEO Paolo Ardoino stated,
“Public blockchains provide authorities with a level of visibility into the movement of funds that simply does not exist with cash, and Tether can act when credible information is provided by law enforcement.”
Tether’s actions transpire as administrations elevate scrutiny on virtual currencies utilized within sanctions evasion and financial crime inquiries. Officials persistently evaluate how blockchain metrics can reinforce regulatory enforcement.
Africa Wallet Expansion Adds New Digital Asset Access
Simultaneously, Tether and Shiga revealed strategies to engineer self-custodial wallets catering to consumers and institutions throughout Africa and the Gulf Cooperation Council territory. The solutions will leverage Tether’s open-source Wallet Development Kit, recognized as WDK.
Shiga intends to roll out ENTA for individual users, high-net-worth participants, and enterprises, whereas Pulse will focus on banks, fintech entities, and institutional clients. ENTA customers will have the ability to fund wallets utilizing local fiat, U.S. dollars, or Bitcoin, prior to holding and transferring USDT, Bitcoin, and Tether Gold.
Pulse will permit institutions to utilize wallet infrastructure supervised by Shiga or deploy the program within their proprietary environments. This configuration grants corporations governance over cryptographic keys, data, and transaction signing routines.
Tether took an equity stake in Shiga Digital during 2025 as the entity crafted services concerning virtual accounts, foreign exchange, treasury administration, and over-the-counter transactions. Shiga noted that its Nigerian Digital Asset Intermediary permit remains under evaluation.
