Binance, the world’s largest cryptocurrency exchange when we look at how much money people trade each day, has sent a formal reply to a letter from United States Senator Richard Blumenthal. The letter asks U.S. government agencies to investigate possible violations of sanctions rules on the Binance platform. Sanctions are government rules that limit who can trade with certain countries. In this case, the focus is on Iran and how people might have used Binance to move money in ways that are not allowed by the law. The Senate inquiry is looking at whether Binance helped anyone break these rules.
Binance’s response says the media reports used in the Senate inquiry contain claims that are false, not supported, and defamatory. “Defamatory” means making statements that could harm a person or company’s reputation. Binance says these claims are not true about its sanctions controls or its anti-money laundering procedures.
Binance emphasizes that it runs a strong compliance program. A compliance program is a system of rules and checks that help a company follow the law and stay out of trouble. Binance says it has more than 1,500 specialists working all over the world. These experts use advanced tools to monitor activity on the platform and to catch anything suspicious early. Binance also says it has been very cooperative with law enforcement agencies. In 2025 alone, the company says it processed more than 71,000 requests from law enforcement. This means the police and other authorities asked Binance for information or help many times, and Binance provided it.
The company adds that its actions helped authorities seize more than $750 million in illicit assets. Of this amount, almost $580 million went to United States agencies. This is money that criminals tried to move or use in illegal ways, and Binance helped stop or recover it.
Binance also claims that its exposure to wallets (digital wallets store cryptocurrency) tied to illegal activity has dropped a lot since early 2024. The drop is about 97% overall, and 97.3% for exposure to major Iranian crypto trading platforms. In simple terms, Binance says it is now less involved with or linked to these bad wallets and platforms than it was before.
Two entities named in the inquiry—Hexa Whale and Blessed Trust—were investigated by Binance and removed from the platform after internal reviews. These reviews were started because law enforcement asked for information. Binance says these steps show the platform is taking the issue seriously. It also says no Binance account carried out direct transactions with Iran-based entities. Binance rejects claims about internal whistleblowers. A whistleblower is someone who reports illegal or improper behavior inside a company. Binance explains that employee departures are a normal part of how companies change over time, not a sign of a problem.
Binance does acknowledge a reality about the digital world. It says that absolute zero risk is impossible on public blockchains. A public blockchain is a type of technology that records all transactions in a way that everyone can see. But Binance says it uses strong monitoring and controls to minimize and reduce risk as much as possible.
The Inquiry Details
In late February, 11 Democratic senators, led by Senator Richard Blumenthal, sent a letter to two U.S. government agencies—the Department of Justice (DOJ) and the U.S. Treasury. They asked for a prompt and thorough review of Binance’s sanctions compliance on the platform. The goal is to make sure Binance is not breaking the law and is not posing a risk to U.S. national security.
The senators cited findings from Binance’s own compliance team from the previous year. These findings claimed that $1.7 billion in digital assets moved to entities linked to Iran. That is a lot of money moving in ways that could violate sanctions rules.
The senators mentioned specific groups to illustrate the risk. They named Iran-backed groups such as the Houthis and the Islamic Revolutionary Guard Corps (IRGC). They also claimed that a Binance vendor directed $1.2 billion in one instance to Iran-linked accounts. The senators wrote that they want a full review to make sure Binance is following the sanctions and does not threaten U.S. national security.
The letter also said that Iranians had access to more than 1,500 Binance accounts. It further claimed that Binance could have been used to help Russia avoid United States sanctions. The senators asked for action to prevent this from happening again and to protect U.S. interests.
