When customers of Iran’s largest cryptocurrency exchange needed to move billions of dollars discreetly and efficiently, they turned to two blockchain networks that would later become deeply intertwined with President Donald Trump’s own digital currency business. On the surface, the Islamic Republic’s sanctioned financial system and a former president’s family enterprise could not appear more disconnected. Yet a closer look at the underlying infrastructure reveals a surprising overlap: the same technological rails that have processed massive volumes for Tehran’s leading exchange were also the ones that helped lend early credibility and reach to Trump’s World Liberty Financial venture.
According to data examined by Reuters, Iran’s Nobitex exchange has processed no less than two point three billion dollars since 2023 using the Tron and BNB Chain ledgers. These blockchains, created respectively by crypto billionaires Justin Sun and Changpeng Zhao, function as tamper-resistant digital record keepers. Every transaction on these networks incurs a fee, which flows to validators and indirectly supports the ecosystems built by Sun and Zhao. For Nobitex, which sits at the heart of Iran’s sanctioned economy, these networks offered a practical solution. They are fast, relatively cheap, and operate outside traditional banking channels that remain largely closed to Iranian entities.
What makes this situation particularly striking is the timeline. Iranian money has continued moving across the Tron and BNB Chain networks during the ongoing military and economic confrontation between the United States and Iran. While the U.S. government has steadily tightened sanctions and pursued a policy of maximum pressure, digital value has quietly flowed through blockchains whose leading figures maintain close ties to the Trump family’s own crypto ambitions. One official familiar with sanctions enforcement, speaking on condition of anonymity, described the situation as a regulatory blind spot that has frustrated multiple administrations. “You can freeze a bank account,” the official said, “but you cannot easily freeze a decentralized ledger. That is the dilemma.”
Adding another layer to this complex picture, both Justin Sun and Binance’s Changpeng Zhao have emerged as prominent backers of World Liberty Financial, the crypto firm co-founded by Trump and his family. Early promotional materials for the venture listed these two figures as key supporters, lending a veneer of industry legitimacy to a project that might otherwise have struggled to gain traction among serious crypto veterans. A former adviser to World Liberty Financial, who left the project before its public launch, recalled internal discussions about the optics of these relationships. “Nobody wanted to turn down capital or credibility from the biggest names in the space,” the former adviser said. “But there were quiet conversations about whether tying the Trump brand so closely to Sun and Zhao could become a political liability down the road.”
For Nobitex, the practical benefits of using Tron and BNB Chain are straightforward. Both networks offer high throughput and low fees compared to Ethereum, which remains the most widely used smart contract platform but suffers from congestion and higher costs during peak periods. Iranian users looking to move value in and out of the country have found these blockchains to be reliable alternatives to formal banking channels, which remain largely inaccessible to Iranian businesses and individuals. A Tehran-based crypto trader who has used Nobitex regularly over the past two years explained the local perspective. “We do not think about who founded the blockchain or where they are from,” the trader said. “We care about whether the transaction settles, how much it costs, and whether our funds arrive safely.”
The juxtaposition is awkward for the Trump administration, which has maintained an aggressive stance toward Iran while simultaneously allowing its principal to remain associated with a crypto venture backed by individuals who indirectly facilitate Iranian capital flows. Critics have pointed to this as an example of how digital assets can undermine traditional sanctions enforcement. Supporters of crypto, however, argue that blockchains are neutral technologies. A blockchain does not check passports or screen for sanctioned entities. It simply processes valid transactions according to its protocol rules.
