Iran's biggest crypto exchange processed at least $2.3 billion in transactions since 2023 using Tron and BNB Chain, the two blockchain networks whose founders are also the most prominent financial backers of World Liberty Financial (WLFI), the crypto company co-founded by members of the Trump and Witkoff families. Trump's three sons, Donald Jr., Eric, and Barron, launched the venture alongside the sons of Steve Witkoff, a Trump special envoy, with Zach Witkoff serving as CEO. Forbes has estimated that Donald Trump has personally earned approximately $550 million from WLFI. According to a Reuters investigation published May 19, 2026, the findings have drawn scrutiny from ethics watchdogs, a sitting U.S. senator, and regulators tracking sanctions compliance across multiple continents.

Reuters reporters Tom Wilson and Gavin Finch documented that Nobitex, an Iranian exchange with 11 million users, routed more than $2 billion through Tron and roughly $317 million through BNB Chain during that period. Separately, Iran's Central Bank used Tron to purchase USDT (Tether's dollar-pegged stablecoin) worth more than $500 million between November 2024 and June 2025. The flows continued after the escalation of U.S. and Israeli military strikes against Iran in early 2026, with an additional $22.6 million moving through BNB Chain and $550,000 through Tron in the period that followed. Reuters noted explicitly that no evidence exists linking Trump or his family members to any knowledge of Nobitex's activity on those networks.

The conflict-of-interest concern centers on the two men who built those networks. Justin Sun, founder of Tron, invested $30 million in WLFI tokens in November 2024 and was named a formal advisor to the company; he later increased his total position to approximately $75 million, accumulating around 4 billion tokens valued at roughly $266 million. Changpeng Zhao (widely known as CZ), founder of Binance which operates BNB Chain, holds a structurally deeper connection: as of October 2025, Binance controlled approximately 84 percent of the USD1 stablecoin supply, which then stood at approximately $4.25 billion, according to a Public Citizen report published around the time of CZ's pardon. Whether that concentration has shifted as the supply has grown to approximately $4.5 billion by May 2026 requires independent verification. USD1 is WLFI's own dollar-pegged token. To put that concentration in context, the industry median for stablecoin supply held by a single entity is 23 percent. In May 2025, MGX, an Abu Dhabi-backed sovereign investment fund, settled a $2 billion Binance investment entirely in USD1, marking the first time a sovereign fund of that scale used a private stablecoin to close such a deal. That relationship carries an additional dimension of concern: a UAE official tied to Sheikh Tahnoon bin Zayed Al Nahyan purchased a 49 percent stake in a related entity four days before Trump's inauguration, routing $187 million to Trump family entities and $31 million to Witkoff entities, raising Foreign Emoluments Clause concerns flagged by Public Citizen.

Binance's sanctions history adds another layer of complexity. Between 2018 and 2022, Nobitex and Binance had an estimated $7.8 billion in direct transaction flows, a figure that contextualizes the structural depth of the Binance-Iran relationship well before the exchange faced U.S. legal action. Binance pleaded guilty in November 2023 to U.S. anti-money laundering and sanctions violations, including transactions involving Iran, and paid a $4.3 billion penalty. CZ served four months in prison. President Trump pardoned CZ in October 2025. Five months later, in March 2026, the Department of Justice was reported to be investigating approximately 2,000 Binance accounts connected to Iranian entities, covering an estimated $1.7 billion in transfers that allegedly occurred after the 2023 settlement. CZ publicly dismissed the renewed scrutiny as politically motivated. The Trump administration separately withdrew more than 21 crypto enforcement cases, including the SEC's lawsuit against Binance, following a Deputy Attorney General memo in April 2025 that directed prosecutors to limit crypto platform enforcement to exceptional circumstances.

The relationship between Sun and WLFI did not hold. In September 2025, WLFI blacklisted Sun's wallet, freezing approximately $107 million in governance tokens after he attempted to transfer them. Sun filed a federal lawsuit against WLFI in April 2026. WLFI, for its part, stated that it "has no relationship with Nobitex," follows U.S. law, and "does not own, operate, or control Tron." White House spokeswoman Anna Kelly dismissed what she described as "bizarre attempts to link President Trump to Iran's banking system," calling them "totally laughable." Nobitex said the flagged transactions moved through its platform "without management approval or awareness." That denial is complicated by a June 2025 cyberattack on Nobitex carried out by a group called Predatory Sparrow, which resulted in approximately $90 million in stolen assets. The breach exposed internal architecture with differentiated controls for high-value or politically connected clients, suggesting a degree of operational sophistication inconsistent with the exchange's claim of institutional unawareness.

The story carries direct consequences for users far outside the United States. In January 2026, Pakistan's government signed a memorandum of understanding with SC Financial Technologies, a Delaware-registered WLFI affiliate, to pilot USD1 for cross-border payments. The agreement was negotiated directly by Zach Witkoff, WLFI's CEO and son of Trump special envoy Steve Witkoff, with Pakistani Finance Minister Muhammad Aurangzeb. Pakistan receives more than $36 billion in annual remittances and has an estimated 40 million crypto users, making the practical case for stablecoin rails straightforward. The MOU was signed in January 2026; two months later, Binance faced a new DOJ investigation into Iran-linked flows, putting the USD1 infrastructure Pakistan had just committed to pilot at renewed legal risk. If USD1 infrastructure were disrupted by an OFAC enforcement action, Pakistani developers and users building on those rails would have limited warning and no ready alternative at comparable scale.

In Nigeria, Kenya, and across Sub-Saharan Africa, Tron-based USDT is the dominant infrastructure for peer-to-peer crypto activity. Transaction fees on Tron often fall below $0.01, making it genuinely irreplaceable for remittances and savings in markets where traditional banking access is limited. The exposure extends into South Asia as well. India ranked first in the 2025 Global Crypto Adoption Index and carries significant Tron and BNB Chain exposure; India's Financial Intelligence Unit is widely anticipated to face new scrutiny pressure in the wake of this investigation, given the scale of Indian participation on both networks. A major enforcement action targeting Tron's or BNB Chain's core infrastructure would affect millions of users engaged in entirely lawful activity, simply because permissionless blockchains make no technical distinction between a migrant worker's $200 transfer and a state-directed $500 million settlement. Public Citizen, a Washington watchdog group, put it plainly: "The same exchange that helped build the infrastructure for and holds the vast majority of Trump's USD1 stablecoin has facilitated billions of dollars in transactions for Iran and designated terrorist organizations." Senator Richard Blumenthal (D-CT) opened a Senate inquiry in February 2026, pressing Treasury and the DOJ to investigate the Binance flows. Nigerian and Kenyan regulators are currently drafting new crypto frameworks. Both processes may accelerate following this investigation, though the direction of enforcement remains uncertain. How regulators respond, particularly whether they target infrastructure-level actors rather than individual wallets, will determine whether the millions of ordinary users who depend on Tron and BNB Chain face collateral disruption from a geopolitical conflict they have no part in.
