When customers of Iran¡¯s largest crypto exchange needed to move billions of dollars, networks created by two of the industry¡¯s biggest players served as conduits.

And from the early stages of U.S. President Donald Trump¡¯s flagship digital currency ?venture, the same two players lent credibility to the startup. According to data, Iran¡¯s Nobitex exchange has processed at least $2.3 billion since 2023 on Tron and BNB Chain, blockchains established respectively under crypto billionaires Justin Sun and Changpeng Zhao. Users of Tron and BNB Chain pay fees to use the blockchains, which serve as secure, tamper-resistant record keepers.

Iranian money has kept moving through those two digital ledgers during the U.S. and Israeli war against the Islamic Republic.
