Senator Richard Blumenthal has intensified his examination of Binance, the world’s largest cryptocurrency exchange, by sending a follow-up letter to co-CEO Richard Teng on April 1. This inquiry emerges amidst growing concerns over potential misrepresentations made by Binance in its previous testimonies to the Senate, particularly regarding financial transactions linked to Iran. Blumenthal’s scrutiny is underscored by recent reports from Fortune and The New York Times, which uncovered that approximately $1.7 billion in transactions flowed from Binance-associated accounts to entities with ties to Iran, a stark contrast to the $110,000 figure Binance previously cited for direct dealings with Iranian exchanges.
The senator expressed alarm over this discrepancy, suggesting it raises serious questions about Binance’s transparency and compliance with Congressional oversight. In his letter, Blumenthal laid out a comprehensive list of inquiries and document requests aimed at uncovering the truth behind these financial flows. He has demanded that Binance disclose whether any accounts were involved in transactions with wallets linked to Iran and provide detailed wallet addresses. Furthermore, he requested a year-over-year breakdown of transactions between Binance and recognized Iranian exchanges, as well as an explanation of the methodology used to arrive at the previously mentioned $110,000 figure.
In addition to financial queries, Blumenthal pressed Binance on its internal compliance mechanisms. He sought clarity on whether the exchange has relaxed its screening processes since January 1, 2025, and whether it has ever chosen not to investigate accounts connected to individuals within Iran, including those using VPNs. The senator also raised concerns about reports of internal compliance staff being dismissed for raising alarms about potential illicit activities, further questioning the exchange’s commitment to regulatory compliance.
Blumenthal’s letter highlights a timeline of alleged inaction by Binance, including delays in responding to law enforcement regarding suspected terrorist financing activities. For instance, he noted that it took the exchange two months to act on warnings about certain entities and a lengthy five months to terminate relationships with a vendor involved in dubious financial activities. As the deadline for Binance to respond approaches on April 14, the implications of this inquiry could have significant ramifications for the exchange and the wider cryptocurrency market, which is already grappling with regulatory scrutiny and calls for greater transparency. The outcome of this investigation may influence public trust in cryptocurrency exchanges and set a precedent for future regulatory measures.
