Tether froze every dollar of USDT held across 131 TRON wallet addresses linked to ISIS-K on July 1, acting within hours of the US Treasury’s Office of Foreign Assets Control adding those wallets to its sanctions blacklist. The move effectively turned those funds into digital paperweights, inaccessible and unmovable.
OFAC’s designation covered 134 crypto wallet addresses in total: 131 on the TRON blockchain and 3 on the Monero network. The Monero addresses present a different problem entirely, since Monero is a privacy-focused cryptocurrency with no central issuer capable of freezing funds. But on the TRON side, Tether’s compliance machinery kicked in fast.
Following the money
According to analysis from Chainalysis, the 131 TRON wallets received over $1.4 million in funds since 2023. Outflows exceeded $880,000, with some of those transactions routed to exchanges based in Syria.
ISIS-K, formally known as ISIL Khorasan, has been designated as a terrorist organization by the US since September 2015. The group has leveraged crypto for fundraising through its media wing, al-Azaim Media Foundation, using digital assets as a way to move money across borders without touching traditional banking rails.
