The U.S. Treasury’s Office of Foreign Assets Control added 134 cryptocurrency addresses linked to Islamic State Khorasan Province, or ISIS-K, to its sanctions list on July 1. The update covers 131 addresses on TRON and three Monero addresses.
The action extends sanctions compliance obligations to identifiable parts of the group’s crypto network. Exchanges, stablecoin issuers and other service providers must screen for the listed addresses and restrict transactions where required.
Blockchain analytics firm Chainalysis said the designated TRON addresses had received more than $1.4 million since 2023 and sent more than $880,000 over the same period. The firm identified transfers involving crypto exchangers in Syria among the activity.
Tether froze balances associated with all 131 listed TRON addresses after the designation. The response illustrates how centralized stablecoin issuers can restrict tokens held at sanctioned blockchain addresses.
ISIS-K is the Islamic State affiliate operating primarily in Afghanistan and Pakistan. The latest Treasury update builds on its existing designation of the group and targets cryptocurrency infrastructure allegedly used to collect and move funds.
