Section 604 on the Line as Senate Returns to CLARITY Act Clock

The Senate returned July 13 with roughly three weeks before the August recess. Section 604, the provision that would bar the federal government from treating non-custodial Bitcoin developers as money transmitters, is one of three live disputes blocking the 60 votes needed for cloture.

The provision that would protect Bitcoin developers from money-transmitter prosecution is one vote-count dispute away from being traded away.

Key takeaways

The Senate returned from recess July 13 with roughly 20 working days before the August break. No cloture motion has been filed on H.R. 3633, the CLARITY Act, as of today.
Section 604, which would bar the federal government from classifying non-custodial Bitcoin developers and node operators as money transmitters, is one of three unresolved disputes blocking the seven-to-nine Democratic crossover votes needed to reach the 60-vote filibuster threshold.
Galaxy Research puts Senate passage odds at roughly 50%, Polymarket at 41-48%. Senator Cynthia Lummis has warned that failure before August recess could push meaningful legislation to 2030.

The Senate returned from its July recess with the CLARITY Act sitting on the Legislative Calendar at General Orders No. 423 and three weeks to act before August. No cloture motion has been filed. The merged text from the Senate Banking and Senate Agriculture Committees, expected the week of July 13, has not been published as of today, meaning the exact language of Section 604 in the Senate version remains unconfirmed.

The House passed H.R. 3633 on July 17, 2025, by a vote of 294-134, per the House roll call record. The Senate Banking Committee cleared a substitute version 15-9 on May 14, 2026, per Congress.gov. Only two Democrats, Ruben Gallego (AZ) and Angela Alsobrooks (MD), voted yes in committee. Both are considered conditional floor votes. Republicans hold 53 seats; Josh Hawley and Rand Paul are expected to vote no. The math requires seven to nine Democratic crossovers.

What Section 604 Actually Does

Section 604, drawn from the Blockchain Regulatory Certainty Act, codifies in statute that non-controlling blockchain developers and infrastructure providers who do not custody or control user funds are not money transmitters under federal law, per the bill text at Congress.gov. It explicitly covers writing or publishing code, providing self-custody hardware or software, and running infrastructure. Bank Secrecy Act registration requirements do not apply.

The provision matters because the legal exposure it addresses is not theoretical. Roman Storm, co-founder of Tornado Cash, was convicted in August 2025 of conspiracy to operate an unlicensed money transmitting business for writing non-custodial code. The DOJ's theory in that case directly implicates Samourai Wallet's developers under the same logic: Keonne Rodriguez and William Lonergan Hill were each prosecuted and sentenced for conspiracy to operate an unlicensed money-transmitting business in connection with non-custodial software, per the DOJ press release. Section 604 closes that gap by turning FinCEN's own 2019 guidance into black-letter law.

The Senate Banking Committee's own myth-vs-fact sheet confirms that the bill includes an explicit "Keep Your Coins" self-custody protection and that DeFi activities including validating, mining, and staking are excluded from intermediary registration requirements, with anti-fraud authority retained separately.

Senator Wyden's push to preserve Section 604 as a safe harbor has kept the provision in the conversation, but the National District Attorneys' Association and allied law enforcement groups are actively lobbying to strip or dilute it. Senators Warner and Cortez Masto have publicly tied their floor votes to law enforcement sign-off on the final language. The White House brokered an endorsement from the National Organization of Black Law Enforcement Executives, but core language remains disputed.

The Three Disputes Blocking 60 Votes

Section 604 is one of three live blockages. The others:

The ethics dispute. Trump's July 1, 2026 financial disclosure put approximately $1.4 billion in 2025 crypto-related income on record, including roughly $635 million from the $TRUMP meme coin and roughly $500 million from World Liberty Financial. Democratic senators have demanded an enforceable conflict-of-interest provision. The White House has refused anything targeting a specific officeholder. A Van Hollen amendment addressing this failed 11-13 in committee.

The stablecoin yield dispute. The American Bankers Association is lobbying to strip yield and rewards language from the bill. This is a fight about altcoin and stablecoin business models and is the least relevant of the three to Bitcoin's position under the final bill.

Sixty-plus industry CEOs and founders have signed a letter to Senate leadership calling Section 604 a non-negotiable condition of industry support. The Davis Wright Tremaine markup analysis tracks the Senate Banking substitute text including Section 604 and the "Keep Your Coins" provision in detail.

Bitcoin's Position If the Bill Survives Intact

Bitcoin is the cleanest beneficiary in this legislation regardless of how the altcoin fights resolve. A blockchain qualifies as "mature" under the bill if it is not controlled by any person or group under common control. Bitcoin satisfies that standard without argument. Mature-blockchain digital commodities receive CFTC-exclusive oversight in spot markets, terminating any theoretical SEC jurisdictional claim permanently. The self-custody protections and the Section 604 developer carve-out compound that: Bitcoin nodes, open-source wallet software, and mining infrastructure all sit explicitly outside the money-transmitter perimeter if the provision holds.

The commodity-pool implications for Bitcoin treasury companies remain a watch item in the Senate substitute text, but the core Bitcoin regulatory picture improves materially if the bill clears without Section 604 being gutted.

The Latham & Watkins US Crypto Policy Tracker pegs the calendar tightly. Stifel analyst Brian Gardner has reportedly indicated the bill likely needs Senate passage by end of July or prospects deteriorate materially. Senator Lummis's warning about 2030 reflects political arithmetic: a November 2026 election that shifts the Senate majority restarts this process from scratch in a new Congress with different priorities.

What to Watch This Week

The merged Senate Banking and Agriculture Committee text is the first gate. When it drops, the Section 604 language will show immediately whether law enforcement pressure has already altered the provision before any floor debate begins. If the merged draft weakens the developer carve-out, the floor fight becomes a rearguard action. If it holds, the question shifts to whether Majority Leader Thune files a cloture motion with enough time for debate, amendments, and a final vote before August 7.

Frequently Asked Questions

The bill as approved by the Senate Banking Committee contains an explicit "Keep Your Coins" self-custody protection and Section 604's developer carve-out covering self-custody hardware and software providers. Regulators retain anti-fraud authority. The Senate's merged text has not been published as of July 13, so any dilution of those provisions will only be visible once that draft is public.

Without Section 604, the legal precedent from the Roman Storm conviction remains live. A Bitcoin wallet developer, Lightning node software maintainer, or mining pool software author could still be prosecuted as an unlicensed money transmitter under existing Bank Secrecy Act interpretation. Section 604 was designed to close that gap by statute. Its removal would leave the DOJ's prosecutorial theory intact and applicable to anyone building non-custodial Bitcoin tools.

Senator Lummis has publicly warned the next viable legislative window could be 2030. If Republicans lose Senate seats in the November 2026 midterms, the coalition that moved this bill to Calendar No. 423 fractures. A new Congress in 2027 restarts the process from the beginning with no guarantee the same provisions survive.
