Summary
- The Office of Foreign Assets Control (OFAC) imposed sanctions on several cryptocurrency wallets linked to Iran's central bank and military, leading Tether to freeze over $131 million across four Tron blockchain addresses.
- On-chain analysts traced the frozen assets back to previous transactions from DTC Pay and Bitso.
- The Treasury also sanctioned seven individuals and entities involved in a global arms procurement network for Iran.
The U.S. Treasury's Office of Foreign Assets Control has sanctioned a number of cryptocurrency wallets connected to Iran's Central Bank and the Islamic Revolutionary Guard Corps, prompting Tether to freeze assets exceeding $131 million across four addresses on the Tron blockchain.
Scott Bessent, the Treasury Secretary, announced the sanctions via a post on X, stating that the U.S. would “aggressively follow the money to deny the Iranian regime access” to illicit funds. In a separate action, the Treasury sanctioned seven individuals tied to a network procuring weapons for the Iranian armed forces, which included a drone parts supplier in Tehran, a Nigerian intermediary, and Russian nationals associated with a Moscow aviation company.

Understanding the significance of this action requires some knowledge of how cryptocurrency operates. USDT, a stablecoin issued by Tether that maintains a one-to-one peg with the U.S. dollar, operates on blockchains like Ethereum and Tron, which Iran has largely been cut off from due to sanctions. Tether has the capability to freeze specific wallet addresses at the software level, making the funds in those wallets inaccessible.
On-chain analyst Specter identified the four affected addresses before the announcement by Bessent, linking them to both the IRGC and the Central Bank of Iran. His findings indicated that most of the funds had been withdrawn from DTC Pay, a payment service provider, and Bitso, a cryptocurrency exchange in Latin America, before they were deposited into the sanctioned wallets.

The transparency of blockchain technology enables such enforcement actions and highlights the vulnerabilities of Iran's crypto strategies. Transactions on public networks like Tron are permanently recorded, allowing U.S. agencies to collaborate with analytics firms in tracking the flow of funds. The more centralized a crypto solution is, the more susceptible it becomes to censorship.
Ari Redford from TRM Labs stated in April that law enforcement can "track and trace the flow of funds to build cases—and potentially seize them” when individuals attempt to cash out at regulated exchanges that must adhere to U.S. regulations.
“It has become this cat and mouse game between the IRGC financial facilitators and National Security (Agencies) to try to stop Iran from off-ramps,” he explained.
Iran has invested years into establishing a crypto framework to bypass sanctions. The nation legalized Bitcoin mining in 2019 and has utilized USDT to stabilize its local currency, the rial, which has been experiencing significant devaluation, while also facilitating international trade. Blockchain analytics firm Chainalysis reported nearly $8 billion in Iranian crypto activity in 2026, while TRM estimates it to be close to $10 billion, with addresses linked to the IRGC making up over half of the country's inflows during the last quarter of that year.
Tuesday's asset freeze is part of a broader initiative known as Operation Economic Fury. Earlier this year, in April, Tether had already frozen $344 million in USDT across two other Tron addresses associated with Iran's central bank. By May, Bessent noted that the U.S. had seized approximately $1 billion in Iranian crypto since the operation commenced. In June, the Treasury placed sanctions on Iran's four largest exchanges, including Nobitex, which alone accounted for over half of the country’s digital asset transactions in 2025.
Tether claims it now collaborates with over 340 law enforcement agencies across 65 nations and has frozen more than $4.4 billion in assets since it began its cooperation with authorities, including over $2.1 billion related to U.S. enforcement actions.
