Crypto Clarity Act Sparks Debate Over Developer Liability in Human Trafficking Cases

The Alliance to End Human Trafficking is urging U.S. lawmakers to reconsider a key provision in the proposed Clarity Act, warning that it could make it more difficult to hold certain cryptocurrency platform developers accountable if their technology is used to facilitate human trafficking or other financial crimes.

The debate centers on Section 604 of the Clarity Act, which states that software developers who do not control customer funds should not be classified as money transmitters. Supporters say the provision merely reflects existing U.S. anti-money laundering policy, while critics fear it could unintentionally create legal loopholes that criminals may exploit in the future.

Katie Boller Gosewisch, executive director of the Alliance to End Human Trafficking, said the organization is concerned that developers could potentially avoid responsibility by arguing they lack direct control over user assets, even if their software is used to process trafficking-related transactions.

The Alliance, together with Catholic Charities, recently sent a letter to Senate Majority Leader John Thune and Senate Minority Leader Chuck Schumer asking lawmakers to revisit the language before the legislation advances.

Speaking on CoinDesk’s The Policy Protocol alongside Rebecca Rettig and Renato Mariotti, Boller Gosewisch said Congress should consider not only how the law applies today but also how sophisticated criminal organizations could use the language in future court cases.

Although she acknowledged she is not an attorney, Boller Gosewisch argued that statutory wording could eventually create reasonable doubt during prosecutions involving developers whose software is linked to illicit financial activity. She compared the issue to civil lawsuits involving hotels, where businesses may have a broader duty of care even if they are not directly involved in criminal conduct.

Rettig, however, rejected the argument that Section 604 creates a new legal shield for crypto developers. She said the provision simply codifies longstanding guidance under the Bank Secrecy Act and interpretations issued by the U.S. Financial Crimes Enforcement Network (FinCEN), which distinguish software developers from money transmitters when they do not take custody of customer assets.

According to Rettig, the proposed legislation does not eliminate criminal liability for individuals who knowingly assist illegal activity. She noted that developers who intentionally facilitate money laundering or other crimes can still be prosecuted under existing federal statutes, including 18 U.S.C. § 1956, as well as other criminal laws.

The discussion reflects a broader policy debate over how cryptocurrency regulation should evolve alongside decentralized technologies. Critics of Section 604 argue lawmakers should anticipate future misuse of blockchain platforms, while supporters believe legislation should remain consistent with existing legal standards and avoid imposing liability on developers who merely create software.

Despite their differing views on the Clarity Act, both sides agreed that combating human trafficking should remain a national priority. Boller Gosewisch called for restoring a federal human trafficking coordinator and increasing financial crime investigations targeting trafficking networks, alongside any legislative changes.

Rettig also emphasized that blockchain technology can strengthen law enforcement efforts because transactions recorded on public ledgers are often traceable, providing investigators with valuable evidence in criminal cases.

As Congress continues to evaluate the Clarity Act and courts consider cases involving decentralized cryptocurrency protocols, the question of developer liability is expected to remain a central issue in the ongoing debate over crypto regulation, anti-money laundering compliance, and efforts to combat human trafficking.
