The US Treasury took a sledgehammer to Iran’s crypto infrastructure on Tuesday. In a single coordinated action, OFAC designated Nobitex, Wallex, Bitpin, and Ramzinex, the four largest cryptocurrency exchanges operating inside Iran, alongside four individuals connected to their leadership.
Combined, these four platforms processed approximately 72% of all Iranian digital asset inflows in 2025. Nobitex alone handled over 50% and served roughly 11 million users. Wallex accounted for 12%. Bitpin handled 10%. Ramzinex processed over $2.45 billion in lifetime transactions.
In a single filing, the Treasury Department cut off nearly three-quarters of Iran’s domestic crypto ecosystem from the global financial system. Every wallet associated with these exchanges is now blacklisted. Every US person or business that interacts with them faces civil or criminal penalties. And any foreign financial institution that continues to process transactions for them risks secondary sanctions that could restrict its access to the American banking system.
Treasury Secretary Scott Bessent framed the action as part of the administration’s “Economic Fury” campaign. “While Iran’s economy is in free fall,” he said, “the regime has chosen to co-opt digital asset technologies for its own corrupt agenda, including evading sanctions and transferring wealth out of the country.”
The sanctions arrive less than a week after Bessent announced the US had seized approximately $1 billion in Iranian cryptocurrency since the enforcement campaign began.
Why Nobitex Matters More Than Any Other Target
Nobitex isn’t just another exchange that processed some sanctioned transactions. It was the backbone of Iran’s entire crypto financial system.
At its peak, the platform handled roughly 70% of Iran’s digital asset activity and served approximately 11 million users in a country of 88 million people. For context, that’s the equivalent of a single exchange serving one in eight Iranians.
OFAC’s designation documents paint a picture of an exchange that served as a core component of the Iranian government’s sanctions-evasion architecture. Nobitex allegedly facilitated hundreds of millions of dollars in stablecoin transactions for the Central Bank of Iran. It processed payments linked to the Islamic Revolutionary Guard Corps. It enabled IRGC-affiliated ransomware operators to move funds. And during internet blackouts that followed US bombing campaigns earlier this year, Nobitex helped the regime move wealth offshore while ordinary Iranians lost connectivity.
The exchange has processed over $2.3 billion in transactions since 2023 for sanctioned Iranian entities, including direct flows linked to the IRGC, which the US has designated as a foreign terrorist organization.
Chainalysis, the blockchain analytics firm that works directly with OFAC, estimates that IRGC-associated addresses accounted for over 50% of total value received by the Iranian crypto ecosystem in the fourth quarter of 2025. Nobitex was the primary platform through which those flows moved.
The People Behind the Platforms
OFAC didn’t just sanction the exchanges. It named and designated their leaders individually.
Amir Hossein Rad, Nobitex’s chairman, co-founder, and former CEO, was designated to help reconstitute the exchange’s operations after a devastating $90 million hack in June 2025. That hack, attributed to a group called Predatory Sparrow (widely believed to be an Israeli cyber unit), crippled Nobitex’s systems and drained significant funds. Rad led the effort to rebuild the platform, keeping Iran’s primary crypto gateway operational despite the attack.
Two co-founders, Ali Kharrazi and Mohammad Kharrazi, were designated as members of the Kharrazi family, which sits inside former Supreme Leader Khamenei’s inner circle. The connection between Nobitex’s ownership and Iran’s highest political leadership directly links the exchange to the regime’s power structure.
Current CEO Seyed Ali Khoee, who previously served as Nobitex’s director of product and marketing, was also designated.
The individual designations matter because they make it personally illegal for these four people to conduct business with any US person or entity, hold property in the US, or transact through any institution that touches the American financial system. Their assets are frozen globally to the extent that US jurisdiction reaches. And any company that employs or contracts with them risks being sanctioned itself.
The Three Other Exchanges and What They Did
Nobitex grabbed the headlines, but the three other sanctioned platforms are significant in their own right.
Wallex, Iran’s second-largest exchange by volume, received approximately 12% of Iranian digital asset inflows in 2025. OFAC alleged that the platform facilitated IRGC-linked transactions and operated as part of a broader sanctions-evasion network that moved value between Iran and international markets.
Bitpin processed roughly 10% of Iranian crypto inflows and allegedly handled millions of dollars in transactions directly linked to the IRGC. The Treasury’s filing described specific transaction patterns linking Bitpin wallets to designated terrorist-financing entities.
Ramzinex, a Tehran-based exchange founded in 2018, has processed over $2.45 billion in lifetime transaction volume. OFAC linked its activity to both the IRGC and a government-backed financial institution, suggesting the exchange served as an intermediary between Iran’s formal banking sector and its crypto ecosystem.
All four exchanges were designated under Executive Order 13224 (counterterrorism) and Executive Order 13902 (Iran’s financial sector). The dual designation means the sanctions apply to both the exchanges’ alleged terrorism financing and their broader role in Iran’s financial system. Any entity owned 50% or more by any of the designated platforms is automatically sanctioned as well.
Together, the four platforms represent the overwhelming majority of Iran’s crypto infrastructure. Sanctioning all four simultaneously is designed to collapse the system rather than force activity to migrate from one platform to another.
The $1 Billion Seizure Number
Treasury Secretary Bessent told Fox Business last month that the US had seized approximately $1 billion in Iranian cryptocurrency since the enforcement campaign began. Tuesday’s Treasury announcement, however, referenced the earlier estimate of nearly $500 million in crypto assets seized.
The discrepancy between the two figures hasn’t been officially explained. It may reflect the difference between assets that are frozen (still held in wallets that have been blacklisted but not yet converted or moved to government control) and assets that are seized (transferred to US government custody). Or it may reflect ongoing operations that haven’t been fully disclosed.
What’s clear is the scale of the financial warfare. In April 2026, Tether froze $344.2 million in stablecoins held across two wallets attributed to the Central Bank of Iran. Those wallets had documented ties to the IRGC-Qods Force and Hizballah. TRM Labs described the freeze as the largest on-chain seizure of Iranian sovereign crypto reserves on record.
The PGSA shipping toll sanctions on May 27 targeted the Bitcoin and USDT collection infrastructure that Iran used to charge commercial vessels for passage through the Strait of Hormuz. And now, the Nobitex designation cuts off the domestic exchange infrastructure that the regime used to convert, store, and move crypto assets.
Each action targets a different node in Iran’s crypto financial network. The toll collection wallets. The central bank’s stablecoin reserves. The domestic exchanges that connected Iranian users to global markets. Taken together, the enforcement campaign has systematically dismantled the infrastructure that Iran built to circumvent traditional financial sanctions through cryptocurrency.
What This Means for the Global Crypto Industry
OFAC’s decision to treat large crypto exchanges in sanctioned jurisdictions as financial infrastructure rather than fringe trading platforms has implications that extend far beyond Iran.
Every global exchange, market maker, OTC desk, and wallet provider that has ever processed a transaction touching an Iranian address now faces heightened compliance risk. The secondary sanctions provisions mean that foreign entities that continue transacting with designated platforms risk losing access to the US financial system, the most powerful economic penalty the Treasury can impose short of military action.
Chainalysis noted that the Iranian crypto ecosystem reached a total value of $7.78 billion in 2025. That money didn’t stay within Iran’s borders. It flowed through international exchanges, DeFi protocols, bridges, and mixing services. Every platform that touches those flows now needs to assess whether it has exposure to the newly sanctioned entities.
For compliance teams at Binance, OKX, Kraken, Coinbase, and every other major exchange, Tuesday’s designations mean updating screening rules, reviewing historical transaction data for Iranian-linked flows, and potentially freezing assets traceable to the sanctioned platforms.
The Nobitex sanctions also establish a template for how the US might approach crypto exchanges in other sanctioned jurisdictions. Russia, North Korea, Venezuela, and Syria all have domestic crypto ecosystems that serve similar functions. If the Treasury decides to apply the same “infrastructure designation” approach to exchanges in those countries, the compliance burden on the global crypto industry would expand significantly.
11 Million Iranians Just Lost Their Primary Crypto Gateway
The human impact of these sanctions is worth acknowledging alongside the enforcement rationale.
Nobitex served approximately 11 million users. Many of them are ordinary Iranians who used the platform not for sanctions evasion or terrorism financing, but for the same reasons people everywhere use crypto: to protect savings from currency depreciation, to send money to family abroad, and to access financial services that their banking system can’t provide.
The Iranian rial has been in freefall for years. Inflation has ravaged purchasing power. The traditional banking system is cut off from international networks. For millions of Iranians, crypto wasn’t a speculative investment. It was a survival tool.
The sanctions don’t distinguish between an IRGC operative moving millions in stablecoins and a teacher in Tehran trying to protect her savings from 50% annual inflation. Both lose access to the same platform. Both face the same restrictions.
That tension between cutting off regime financing and harming ordinary citizens is inherent in every sanctions regime. The Treasury’s position is that the exchanges’ leadership knowingly facilitated terrorist financing and sanctions evasion, making designation necessary regardless of the collateral impact on individual users. Critics argue that broad platform sanctions punish populations for the actions of their governments.
The 11 million Nobitex users will now need to find alternative platforms, migrate to peer-to-peer trading, or abandon crypto entirely. For Iran’s regime, the sanctions represent an economic blow. Iran’s people represent the loss of one of their few remaining connections to the global financial system.
FAQ
Which Iranian exchanges were sanctioned?
OFAC designated four platforms on June 2, 2026: Nobitex (50%+ of Iranian crypto inflows), Wallex (12%), Bitpin (10%), and Ramzinex ($2.45 billion in lifetime volume). Four individuals connected to the exchanges’ leadership were also designated, including Nobitex’s chairman, current CEO, and two co-founders from Supreme Leader Khamenei’s inner circle.
How much Iranian crypto has the US seized?
Treasury Secretary Bessent said the US has seized approximately $1 billion in Iranian cryptocurrency, though Tuesday’s official filing referenced the earlier estimate of nearly $500 million. In April, Tether froze $344.2 million in stablecoins attributed to the Central Bank of Iran. The total includes assets frozen through sanctions, seized through enforcement, and blocked through cooperation with stablecoin issuers.
Does this affect non-Iranian crypto users?
Not directly, but the secondary sanctions provisions create compliance risks for global exchanges and financial institutions. Any entity that processes transactions for the designated Iranian platforms risks losing access to the US financial system. Global exchanges need to update screening rules and review historical data for Iranian-linked flows. The designations also establish a template that the US could apply to crypto exchanges in other sanctioned jurisdictions.
