CoinEx Rejects $3.84 Billion Iran Sanctions Gateway Allegations Firmly

CoinEx Pushes Back Against TRM Labs’ Allegations

Crypto exchange CoinEx has rejected allegations that it acted as a $3.84 billion gateway for sanctioned Iranian cryptocurrency firms, disputing findings published by blockchain intelligence company TRM Labs. The dispute follows a report claiming the Seychelles-based exchange processed billions of dollars in blockchain-traced transactions involving Iranian entities that have been targeted by U.S. sanctions.

According to TRM Labs, more than $3.84 billion in cryptocurrency flows moved between CoinEx and over 60 Iranian crypto platforms during the past seven years. The report identified Iran’s largest exchange, Nobitex, as CoinEx’s biggest counterparty, accounting for approximately $2.7 billion of those transactions.

CoinEx strongly disputed those conclusions, stating that blockchain transactions alone cannot establish intent, awareness, or active facilitation of sanctions violations.

Exchange Says On-Chain Activity Does Not Prove Wrongdoing

In its official response, CoinEx said it has never maintained commercial relationships with Iranian government entities or domestic Iranian exchanges. The company argued that blockchain networks are inherently open and that digital assets routinely pass through multiple wallets and exchanges without implying knowledge or participation by every intermediary.

CoinEx also questioned the methodology used by blockchain analytics firms, noting that different providers often generate varying transaction estimates because they rely on different attribution models and data sets. The exchange emphasized that on-chain flows should not automatically be interpreted as evidence of sanctions evasion.

Sanctions Pressure Intensifies Across Iranian Crypto Markets

The allegations arrive during heightened regulatory scrutiny of Iran’s cryptocurrency ecosystem.

Earlier this month, the U.S. Treasury expanded sanctions targeting several Iranian cryptocurrency exchanges, including Nobitex, as part of broader efforts to disrupt financial networks allegedly supporting sanctioned organizations. These measures have increased pressure on global exchanges to strengthen compliance controls and customer screening procedures.

TRM Labs further claimed that CoinEx had transaction exposure involving wallets allegedly connected to sanctioned organizations, although the report stopped short of accusing the exchange of intentionally facilitating illegal activity. Instead, the findings focused on blockchain-traced fund movements between wallets associated with sanctioned entities and the exchange.

CoinEx Says It Is Reducing Iran-Related Exposure

CoinEx stated that it has already begun reviewing and exiting remaining Iran-related business following the latest U.S. sanctions announcements.

The exchange said its compliance program continues to evolve alongside changing international regulations and reiterated that it actively monitors sanctioned addresses while strengthening risk controls. According to the company, compliance decisions are updated whenever new regulatory requirements emerge.

The company also stressed that many blockchain transactions involve indirect routing across multiple platforms, making attribution significantly more complex than traditional financial transfers.

Broader Implications for the Crypto Industry

The dispute highlights one of the cryptocurrency industry’s most persistent regulatory challenges: distinguishing between passive blockchain exposure and active facilitation of sanctioned transactions.

Blockchain intelligence firms increasingly use transaction tracing to identify fund flows across exchanges, while exchanges argue that open blockchain infrastructure means assets frequently transit through platforms without operator knowledge or approval.

As regulators worldwide tighten anti-money laundering and sanctions enforcement, centralized exchanges face growing expectations to enhance transaction monitoring, customer verification, and blockchain analytics capabilities. The outcome of debates such as the one involving CoinEx and TRM Labs may influence future compliance standards across the digital asset industry.

For now, the allegations remain disputed. TRM Labs maintains that its blockchain analysis demonstrates extensive financial connections between CoinEx and sanctioned Iranian entities, while CoinEx insists the reported transaction flows do not establish complicity and denies any intentional assistance to sanctioned parties.
