The seized assets include cryptocurrencies, real estate and other monetary assets related to Helix’s operations. Mixing services like Helix are designed to mix multiple users’ cryptocurrencies and route funds through complex transactions, making it difficult to trace their origins or destinations.
Helix operator Larry Dean Harmon previously pleaded guilty in August 2021 to conspiracy to commit money laundering. In November 2024, he was sentenced to 36 months in prison, three years of supervised release, and sentenced to forfeiture of his property and a money judgment. On January 21, Judge Beryl A. Howell of the District Court for the District of Columbia issued a final order of forfeiture, officially transferring the assets to the government.
Helix’s Role in Darknet Markets
According to court documents, Helix was one of the most popular mixing services on the darknet. He processed at least 354,468 bitcoins, or about $300 million at the time, for clients who often traded on darknet drug markets. Harmon charged fees for these transactions, making Helix a lucrative operation. He also developed Grams, a darknet search engine and application programming interface, or API, that allowed major darknet marketplaces to integrate Helix directly into their bitcoin withdrawal systems. Investigators traced tens of millions of dollars to illegal markets through Helix.

This case highlights the growing sophistication of cybercrime and the tools used to launder digital assets. Helix’s integration with several darknet platforms shows how criminal networks have exploited the technology to hide illicit funds. It also reflects a broader trend in cryptocurrency enforcement, with U.S. authorities increasingly focusing on tracing crypto flows to recover stolen or illicit funds. Since 2020, the Criminal Division’s Computer Crime and Intellectual Property Section has secured convictions for more than 180 cybercriminals and returned more than $350 million to victims.
Implications for Crypto and Investors
The Helix affair is a reminder that digital assets are still closely monitored by the authorities. Although cryptocurrency provides privacy and security, it does not protect illegal activities from law enforcement. Regulatory monitoring and investigation tools are evolving alongside blockchain technology. Create a landscape where compliance and transparency matter.

A concrete example is the use of blockchain analysis companies, which have made it possible to trace transactions between mixers and identify illicit activities. These tools are now standard in surveys. This means that exchanges and users may face greater responsibility for the origin and destination of funds.
