OFAC sanctions 134 ISIS-K crypto wallets as Tether freezes funds

TL;DRAI · 60 sec read

The US Department of the Treasury's Office of Foreign Assets Control has sanctioned 134 cryptocurrency wallet addresses linked to ISIS-Khorasan, with Tether freezing the balances on 131 of them.

OFAC adds ISIS-K wallets to its sanctions list. The addresses were placed on the Specially Designated Nationals list on July 1, 2026. This includes individuals, entities and digital asset addresses connected to terrorism and other illicit activity. ISIS-K has been designated a Specially Designated Global Terrorist since September 2015.

Some wallets sent funds to Syria-based cryptocurrency exchanges, showing significant exposure to mainstream services.

The sanctions cover 131 Tron addresses and three on the Monero network. Blockchain forensics firm Chainalysis reported the action in a report published the same day.

Tron addresses received over $1.4 million in donations. The 131 Tron wallets received more than $1.4 million in crypto donations since 2023, according to Chainalysis. Those addresses sent over $880,000 during the same period. ISIS-K has solicited crypto through donation campaigns on websites and messaging platforms.

Chainalysis identified multiple donation addresses used by the group on Tron, Monero and Bitcoin networks. Some wallets sent funds to Syria-based cryptocurrency exchanges, showing significant exposure to mainstream services.

Indonesian courts treated wallet addresses, transaction histories and on-chain flows as admissible evidence that can anchor prosecutions.

Tether freezes sanctioned Tron balances. Stablecoin issuer Tether has frozen the balances associated with the 131 Tron addresses. The three Monero addresses remain on the sanctions list without similar freezing reported. The action follows OFAC's prior sanctions on June 22 targeting ISIS-supporting financiers.

The June 22 measures hit three individuals and six entities across Europe, the Middle East and West Africa. Those included the Syria-based MSB Bitcoin Xchange and Turkish MSB Spider. OFAC described them as key facilitators enabling ISIS to move funds among regional affiliates.

Blockchain analytics tools gain role in sanctions enforcement. The latest sanctions highlight the growing use of blockchain intelligence in targeting illicit finance. In April, blockchain intelligence company TRM Labs noted that onchain evidence helped secure terrorism financing convictions in Indonesia in 2024 and 2025. Indonesian courts treated wallet addresses, transaction histories and on-chain flows as admissible evidence that can anchor prosecutions.
