New internal documents obtained by Fortune reveal that Binance investigators discovered a network of accounts, including those belonging to VIP Chinese traders and a suspected Iranian gold smuggler, facilitated the movement of approximately $1 billion to groups linked to Iran.

According to the documents, these transactions occurred during early 2025 as Iran's regime increasingly turned to cryptocurrency to circumvent economic sanctions. The investigation identified specific accounts that acted as conduits for moving substantial sums through the platform.

Key Findings from the Documents

VIP Chinese Traders Involved: The documents show that high-value Chinese traders on Binance played a role in the transaction network, though the exact nature of their involvement remains under investigation.

Suspected Iranian Gold Smuggler: One account was linked to an individual suspected of being involved in gold smuggling operations, suggesting potential connections between traditional illicit finance and cryptocurrency channels.

Scale of Activity: The $1 billion figure represents a significant volume of transactions that investigators believe were structured to obscure their ultimate destination and purpose.

Context and Implications

The revelations come amid heightened scrutiny of cryptocurrency exchanges' compliance with international sanctions. Binance has faced regulatory pressure globally over its anti-money laundering practices and has previously settled with regulators for billions in fines.

Iran has been under comprehensive economic sanctions for years, and the regime has increasingly explored cryptocurrency as a means to access international markets and finance operations. The use of major exchanges like Binance for such purposes raises questions about platform oversight and compliance mechanisms.

Regulatory Response

While the documents don't indicate Binance's current stance on these findings, the exchange has historically cooperated with law enforcement investigations. The scale and sophistication of the network described in the documents suggest organized efforts to exploit cryptocurrency platforms for sanctions evasion.

Financial regulators worldwide have been working to strengthen oversight of cryptocurrency transactions, particularly those that might facilitate sanctions violations or other illicit activities. This case highlights the ongoing challenges in balancing crypto innovation with compliance requirements.

Broader Crypto Compliance Landscape

This investigation is part of a larger pattern of concerns about cryptocurrency's role in international finance. Major exchanges have invested heavily in compliance infrastructure, but determined actors continue to seek ways to use digital assets for purposes that violate sanctions and other regulations.

The documents underscore the complex intersection of cryptocurrency, international sanctions, and illicit finance networks, demonstrating how digital assets can be exploited for purposes that regulators and law enforcement agencies are working to prevent.

The full details of the investigation and Binance's response to these findings remain under review, but the documents provide a concerning window into how cryptocurrency platforms can be used to facilitate large-scale financial flows that may violate international law.
