The National Sheriffs’ Association is renewing its opposition to the CLARITY Act’s decentralized finance (DeFi) provisions, and the Blockchain Association says the law enforcement group has it backwards.
Key Takeaways
The National Sheriffs’ Association sent Thune and Schumer a fresh CLARITY Act warning.Blockchain Association’s Lindsay Fraser believes the NSA’s position comes from a place of “fundamental misunderstanding.”The dispute centers on Section 604, which shields non-custodial software developers.The National Sheriffs’ Association sent a letter to Senate Majority Leader John Thune and Democratic Leader Chuck Schumer warning that the CLARITY Act, as currently written, would create broad exemptions from registration, know-your-customer, anti-money-laundering, and sanctions-law requirements for certain decentralized-finance participants, potentially allowing illicit actors to exploit platforms and services designed to obscure digital-asset transactions.
The sheriffs’ group is not acting alone, joining the National District Attorneys Association, the National Association of Assistant United States Attorneys, and the International Association of Chiefs of Police in warning that the bill’s treatment of DeFi could open gaps traffickers, sanctions evaders, and money launderers would exploit, a coalition whose joint letter dates to late June and whose core argument has been echoed in each NSA letter since.
The specific target of the coalition’s objection is Section 604 of the bill, a provision commonly referred to as the Blockchain Regulatory Certainty Act, which carves out protections for developers who build non-custodial software, wallets, and protocols without ever taking control of user funds.
Law enforcement groups argue that carve-out is written broadly enough to let genuinely custodial or laundering-facilitating operations claim the same shield, weakening Know-Your-Customer and Anti-Money-Laundering standards relative to what traditional financial institutions must follow.
The Industry’s RebuttalThe Blockchain Association has not let the argument go unanswered, sending out a message of clear pushback.
Section 604 does one narrow thing: it prevents non-custodial software developers from being misclassified as money transmitters when they do not custody assets or control transactions.
She went further in rejecting the idea that the provision creates a loophole for bad actors, stating plainly that it “does not immunize criminals,” “does not limit sanctions enforcement,” and “does not stop prosecutions for money laundering, fraud, or terrorist financing.”
A Split That Could Decide the VoteThe standoff illustrates why the CLARITY Act’s law enforcement question has become its own subplot inside the broader Senate fight. Unlike the ethics dispute over Trump’s crypto business ties or the stablecoin oversight questions that have separately slowed negotiations, the Section 604 fight pits working law enforcement organizations directly against the industry group lobbying hardest for passage, with both sides claiming to represent public safety.
