Key Takeaways
- Four law enforcement groups warned that the Clarity Act’s developer safe harbor could create oversight gaps in crypto crime investigations.
- The DOJ pushed back, saying the letter contained factual inaccuracies and that investigative access would not change under the bill.
- Prediction market odds for the Clarity Act’s passage have dropped from above 75% to around 42% as the controversy intensifies.
Four major U.S. law enforcement organizations sent a joint letter to Acting Attorney General Todd Blanche and White House crypto adviser Patrick Witt on June 23, warning that Section 604 of the Clarity Act could create oversight gaps and weaken investigative tools used in crypto crime cases.
The Department of Justice pushed back the following day, saying the letter contained factual inaccuracies and mischaracterized administration policy.
Letter Targets Developer Safe Harbor in Section 604
The letter was signed by the National District Attorneys Association, the National Association of Assistant United States Attorneys, the International Association of Chiefs of Police, and the National Sheriffs’ Association, organizations representing more than 70,000 law enforcement professionals.
Section 604, also known as the Blockchain Regulatory Certainty Act, began as a standalone bill before being incorporated into the Clarity Act. It establishes that non-custodial developers and infrastructure providers are not money transmitters when they do not hold customer funds or control transactions. The groups warned the provision’s language is too broad.
“Our concern is not with individuals who merely write or publish software code, nor with responsible technological innovation,” the letter said.
“Rather, our concern is with broad exemptions that may shield individuals or entities whose activities facilitate the movement of digital assets, create obstacles to legitimate oversight, or weaken longstanding investigative and enforcement authorities relied upon by law enforcement.”
The groups also argued that additional provisions in the bill could reduce transparency, limit accountability, and create gaps in the anti-money laundering framework more broadly.
DOJ Rejects Claims That Clarity Act Weakens Crypto Crime Probes
A DOJ spokesperson responded on June 24, saying the letter contained factual inaccuracies and mischaracterized administration policy. The spokesperson said law enforcement’s access to relevant information would not change under the Clarity Act.
White House crypto adviser Patrick Witt has previously described the bill as a “pro-regulatory, pro-enforcement” measure.
“Money is moving faster globally, and if we are not setting standards as the United States, then we are going to be receivers of somebody else’s playbook,” he said earlier this month.
The Blockchain Association’s chief policy officer Lindsay Fraser also rejected the criticism, arguing that Section 604 only exempts non-custodial software developers who cannot move, freeze, or control user assets.
Blockchain analytics firm TRM Labs separately published a section-by-section analysis arguing that Section 604 preserves criminal liability under 18 U.S.C. § 1960(b)(1)(C), which applies to those who knowingly transfer funds derived from or intended for unlawful activity, meaning the carve-out does not extend to knowing facilitators of illicit finance.
Anti-Trafficking Advocates Warn Section 604 Could Aid Illicit Finance
More than 80 Catholic leaders, women religious, anti-trafficking advocates, and survivor leaders signed a separate letter the same day to Senate Republican Leader John Thune and Senate Democratic Leader Chuck Schumer, urging lawmakers to reconsider Section 604.
The Alliance to End Human Trafficking said the provision could create regulatory ambiguities that make it harder to monitor financial flows tied to human trafficking, child exploitation, organized crime, and sanctions evasion.
Senator Cynthia Lummis, a principal sponsor of the Clarity Act, pushed back on those concerns in a separate statement, saying the legislation makes clear that writing software code does not constitute money transmission and that the bill closes the gaps bad actors exploit.
Section 604 Dispute Pushes Clarity Act Passage Odds Down to 42%
The Clarity Act cleared the Senate Banking Committee on a 15-9 vote earlier this month and is on the Senate calendar but requires 60 votes to advance to a floor vote before the August recess. Section 604 has emerged as one of several unresolved disputes alongside debates over DeFi oversight, stablecoin yield provisions, and Democratic support.
Prediction market data showed approval odds for the Clarity Act falling from above 75% to around 42% as the Section 604 controversy intensified through late June.
