The U.S. Treasury's Office of Foreign Assets Control on July 1, 2026 added 134 cryptocurrency wallet addresses tied to ISIS-Khorasan as identifiers in a broader sanctions action targeting financial networks associated with ISIS. Chainalysis said the addresses included 131 on TRON and three on Monero; the TRON wallets had received more than $1.4 million since 2023 and sent over $880,000, and Tether froze balances in all 131 TRON addresses. The action follows earlier OFAC moves against Syrian money service businesses and other ISIS-linked facilitators, underscoring continued regulatory and compliance pressure on crypto networks used for illicit finance.
