The US Treasury just took a sledgehammer to Iran’s crypto infrastructure. On June 2, the Office of Foreign Assets Control designated Nobitex, Iran’s largest digital asset exchange, alongside three other platforms, in a move designed to choke off one of the regime’s most important financial lifelines.

Nobitex alone handled over 50% of all Iranian digital asset inflows in 2025. More than half of every crypto dollar flowing into Iran passed through a single exchange that the US government says has direct ties to the regime’s inner circle.

Four exchanges, one message

OFAC didn’t stop at Nobitex. The designations, issued under Executive Orders 13224 and 13902, also hit Wallex, Bitpin, and Ramzinex.

Wallex accounted for 12% of total Iranian crypto inflows in 2025. Bitpin handled 10%. Ramzinex has historically processed over $2.45B in digital assets. And Nobitex, at its peak, managed roughly 70% of Iran’s entire digital asset activity with approximately 11 million users.
