Senator Ron Wyden (D-OR) has formally written to Senate leaders urging them to keep Section 604 of the CLARITY Act intact as the bill moves toward a floor vote. <cite>In a letter addressed to Senate Majority Whip John Thune and Senate Minority Leader Chuck Schumer, Wyden argued that removing Section 604, known as the Blockchain Regulatory Certainty Act (BRCA), would undermine both innovation and sensible law enforcement.</cite>
<cite>The BRCA was originally introduced as a standalone bill by Senator Cynthia Lummis (R-WY) earlier this year before being integrated into the broader CLARITY Act. Wyden is the sole Democratic co-sponsor of the provision.</cite>
<h2 id="what-section-604-would-do">What Section 604 Would Do</h2>
<cite>At its core, the BRCA would create a legal safe harbor ensuring that developers of non-custodial blockchain software, code that never holds or controls user funds, are not classified as money transmitters under the Bank Secrecy Act, a designation that carries licensing, know-your-customer, and anti-money-laundering obligations.</cite>
<cite>Wyden argued the provision simply codifies existing federal policy, clarifying that developers should not be treated as money transmitters solely because they create or publish software. That position, he wrote, reflects established guidance from the Financial Crimes Enforcement Network (FinCEN) and is consistent with emerging case law.</cite>
<cite>Crucially, Wyden pointed to a built-in exception: any non-custodial developer found to be transferring or using funds originating from illicit activity would not be protected, so bad actors can still be held accountable while neutral software developers are not treated as financial intermediaries.</cite>
<h2 id="a-contested-provision-with-high-stakes">A Contested Provision With High Stakes</h2>
<cite>Despite industry support, some law enforcement agencies have voiced opposition to the BRCA, with their primary concern being that the provision could weaken safeguards used to combat human trafficking, money laundering, and other illicit activities.</cite> Wyden pushed back on those claims directly, <cite>arguing that critics have been inaccurately claiming that the bill would weaken anti-money-laundering and counter-terrorism-financing laws.</cite>
<cite>Without the provision, he warned, blockchain innovation risks migrating offshore to jurisdictions with clearer rules.</cite> The CLARITY Act is targeting a Senate floor vote on July 17, after lawmakers return from recess, though <cite>passage odds have been hovering around 40 to 50 percent</cite> amid several unresolved disputes.
<cite>For the DeFi protocol ecosystem, where developers currently face sustained legal uncertainty, Section 604 represents the bill's most practically significant innovation.</cite>
