Tether has frozen USDT balances in all 131 TRON wallets linked to ISIS-K after the U.S. Treasury’s Office of Foreign Assets Control added the addresses to its sanctions list. Chainalysis said the TRON wallets had received more than $1.4 million since 2023 and sent out over $880,000.
OFAC Adds ISIS-K Crypto Wallets To Sanctions List
OFAC updated its designation of ISIL Khorasan, also known as ISIS-K, by adding 134 cryptocurrency wallet identifiers tied to the group. The update included 131 TRON addresses and three Monero addresses, according to the details cited by Chainalysis.
ISIS-K is the Afghanistan and Pakistan affiliate of the Islamic State network, and the group has operated across parts of Central and South Asia. Its media arm, al-Azaim Media Foundation, has historically used online channels to spread propaganda and solicit crypto donations.
The designation means U.S. persons must block property and interests in property connected to the listed identifiers. Regulated firms are also expected to screen for exposure to the wallets and prevent transactions involving sanctioned parties.
Chainalysis Tracks $1.4M In TRON Wallet Activity
Chainalysis reported that the sanctioned TRON wallets received more than $1.4 million in cryptocurrency since 2023. The firm also said the addresses sent over $880,000 during the same period, including transfers involving mainstream services and Syria-based crypto exchangers.
The presence of TRON addresses points to the role of low-cost blockchain networks in illicit finance monitoring. TRON has become widely used for stablecoin transfers, especially USDT, because transaction costs are often lower than on some other networks.
OFAC also added three Monero addresses to the ISIS-K designation. Monero’s privacy features make tracing more difficult, although the inclusion shows that regulators continue to identify privacy-coin addresses linked to sanctioned entities.
Tether Freeze Shows Stablecoin Compliance Controls
Tether’s freeze affects USDT balances held in all 131 listed TRON wallets. The action demonstrates how centralized stablecoin issuers can restrict sanctioned addresses when tokens are issued on networks that support issuer-level blocking.
The case also adds to earlier U.S. actions involving ISIS-linked crypto financing. Chainalysis cited previous sanctions connected to Maldives-based ISIS-K operative Ali Shafiu and Syrian money service businesses accused of serving ISIS financiers.
OFAC separately sanctioned two Brazilian nationals and four companies tied to Primeiro Comando da Capital, a Latin American criminal organization. According to OFAC, that network laundered more than $30 million in illicit proceeds and used cryptocurrency to move funds back to Brazil.
The latest action places fresh compliance pressure on crypto exchanges, stablecoin firms, and virtual asset service providers. For investors and market participants, the development shows that blockchain activity tied to sanctioned groups remains a core focus for regulators, while stablecoin issuers continue to face demands to act quickly when sanctioned wallets are identified.
