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

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.

Update, July 14, 2026

Senate Majority Leader John Thune has not allocated floor time for H.R. 3633 as of today, and no cloture motion has been filed, even as negotiators aim to drop the merged Banking-Agriculture text this week and push toward a July 20 floor vote target. Getting from two Democratic committee votes to seven or more on the floor requires resolving the conflict-of-interest provision, filing cloture, and burning the better part of a Senate work week on debate and passage before August 7. The official Senate schedule lists August 10 through September 11 as the next state work period, making Friday, August 7 the final day of the pre-recess window.

The names are now on record. A trio of Senate Democrats made a public opposition case at a Washington press conference, arguing that unless the bill directly addresses President Trump's personal crypto ties it should not advance. Senators Chris Murphy, Chris Van Hollen, and Jeff Merkley solidified that position, one also associated with Senator Elizabeth Warren.

Senators Kirsten Gillibrand, Murphy, Van Hollen, and Merkley have collectively conditioned their support on inclusion of a crypto ethics provision that would bar sitting presidents, members of Congress, and their spouses from issuing, sponsoring, owning, or profiting from digital assets. This is the faction that controls the margin: the bill cannot reach 60 votes without peeling some of them off or replacing them with other Democratic crossovers who have not yet surfaced.

The merged draft expected this week is not going to solve that problem on its own. The forthcoming draft omits the ethics provision Democrats have made a precondition, and without that language, securing the seven or more Democratic votes needed to clear the 60-vote cloture threshold looks structurally difficult before the August recess.

Even the two Democrats who voted to advance the Banking Committee version warned that they may not approve the final version if it does not address their outstanding concerns, including the ethics provision, and the White House has not signed off on the merged text or engaged in the most recent negotiations.

According to Fox Business reporter Eleanor Terrett, "an ethics agreement is the key to unlocking the rest of the negotiations."

What is not under serious threat is Section 604. The developer carve-out that would bar FinCEN from classifying non-custodial Bitcoin developers and node operators as money transmitters remains in the bill and is not the provision Democrats are using as their blocking instrument. The competing Senate floor calendar is further crowded by FISA reauthorization and the NDAA. Stifel's Brian Gardner wrote that "in order for the CLARITY Act to pass in 2026, it probably needs to get through the Senate by the end of July, preferably in June," adding that "if the Senate fails to pass the bill before the August recess, the bill's prospects would deteriorate materially." After August 7, the fall calendar bends toward midterm campaigning and must-pass spending fights, and the structural conditions for a bipartisan deal only get harder from there.

Update, July 21, 2026

The ethics logjam broke. The White House reached an agreement on the CLARITY Act's ethics provision and began sharing the language with Republican senators, according to Eleanor Terrett of Crypto in America, one of the more reliable primary sources tracking the bill's progress through Congress. The ethics provision was discussed during a July 16 meeting between President Trump, Republican Senators Bernie Moreno, Cynthia Lummis, Tom Tillis, and Bill Hagerty, and White House crypto adviser Patrick Witt. No agreement was reached at that meeting, but The Block reports the measure received the president's sign-off later that Monday evening. The specifics of the compromise have not been made public, and revised legislative language is expected in the coming days. Context matters here: a prior compromise that would have authorized state attorneys general to enforce ethics rules collapsed after Democrats rejected it as inadequate, and a Senate committee amendment from Senator Chris Van Hollen failed 13-11 along party lines, meaning the July 20 agreement is the third attempt to thread this needle.

Trump's sign-off settles the Republican side of the ledger. It does nothing yet to move the Democrats who determine whether this bill lives. Democrats said Monday that they have been largely excluded from the ethics negotiations in recent weeks, including the White House meeting last Thursday. A separate faction of Senate Democrats held a press conference characterizing the CLARITY Act as a corrupt bill and threatening to block it, but that group notably excluded both Gallego and Alsobrooks, meaning the bipartisan path to 60 votes remains structurally intact if the ethics language satisfies the two Democrats who actually matter to the arithmetic. Senator Kevin Cramer told Fox Business the bill grows "clearer" as each issue gets resolved and pointed to DOJ as the likely prevailing enforcer on ethics. Treasury Secretary Scott Bessent added his voice Tuesday, telling Bloomberg that lawmakers stood at the "1-yard line" and urging Congress to pass the bill before the recess. That is not cheerleading from Treasury. It signals that principal-level resistance has cleared.

Prediction markets registered the shift. Polymarket's contract on the CLARITY Act being signed into law in 2026 moved to 42% following the reports, recovering from the mid-to-high thirties earlier in the week, though still well below the roughly 80% it commanded in February. House Financial Services Committee Chairman Bryan Steil said the bill could pass within days. Senate Majority Leader Thune has said he intends to press forward with a floor vote before the August break regardless of whether every detail is nailed down, though Senator Cramer stopped short of a firm date, saying "I don't know that we get to it this week."

One more signal worth noting on the execution side. Patrick Witt, executive director of the White House Crypto Council, had been reported set to leave for mandatory Georgia Army National Guard training just as the bill reached the Senate floor. Witt confirmed on July 20 that his training has been deferred and that he remains committed to helping complete the effort. David Sacks also noted Witt's continued involvement. Administrations do not reschedule military obligations for legislation they expect to fail. Three things still need to occur in sequence: the revised bill text must be released with the ethics language included, Democrats must see it and decide whether it meets the standard they set, and Thune must find floor time before August 7. The merged Banking-Agriculture text remains unpublished, but between Bessent's on-record framing, the ethics resolution, and the narrowing calendar, the bill is closer to the finish line today than at any point this cycle.

Update, July 23, 2026

Senate Republicans dropped an updated CLARITY Act draft on July 22 following morning briefing calls with stakeholders. The revised text carries a crypto ethics provision for the first time, barring the president, vice president, members of Congress, federal judges, and other covered officials from issuing or sponsoring digital assets.

Covered officials would be required to sell their crypto holdings and investments in crypto-related companies or place them in a blind trust they do not control, and the Department of Justice would hold civil enforcement authority over violations.

The ethics provisions carry no force after noon on January 20, 2029, and the timing aligns with the end of the current presidential term.

Eleanor Terrett reported the package was negotiated between the White House and Republican Senators Cynthia Lummis and Bernie Moreno, and that it does not carry Democratic sign-off. That last part is the sticking point. Lummis told CoinDesk that having state attorneys general bring criminal or private cases under the ethics provision was a "red line" for Republican negotiators, and that the ethics language is likely to be discussed through the weekend alongside a few other issues in the bill.

Draft language has been shown to crypto industry insiders, and the Senate has only days remaining before the August recess.

Section 604 is intact in the new draft. The legislation retains the Blockchain Regulatory Certainty Act provisions, stablecoin measures, and adds a new law enforcement section.

Polymarket odds of the CLARITY Act passing dropped to 39% after Senate Republicans released the new draft , a signal that markets read the Democratic exclusion from negotiations as a real obstacle, not a procedural formality. The draft's existence is progress. Democrats without a seat at the table when the language was written is not.

Update, July 29, 2026

Senate Republicans circulated a merged draft on July 22 that included an ethics provision barring the president, vice president, members of Congress, federal judges, and their spouses from issuing or sponsoring digital assets for compensation while in office -- with the restriction set to expire at noon on January 20, 2029.

Democrats countered that the Justice Department should not be the sole enforcer of a ban on elected officials issuing crypto, and senators who had supported earlier versions of the bill vowed to oppose this one.

Senator Thom Tillis also signaled he would not support the bill without changes to the ethics section, compressing the GOP coalition's room to maneuver, and Polymarket odds on 2026 passage fell to approximately 38% by the morning of July 23.

Now, per CoinDesk's July 29 reporting, a bipartisan pair of senators has been working a counter-proposal aimed at toughening the ethics concession Trump accepted -- an effort that was subsequently walked back in negotiations. That back-and-forth is the clearest signal yet that the ethics section remains live and contested at the staff level even as the pre-recess clock winds down.

Majority Leader Thune moved to a Russia sanctions bill and federal nominations ahead of the CLARITY Act, with floor action on crypto potentially shifting the next window to September.

While some floor time returns in September, lawmakers will be increasingly focused on November midterms, and the first week of August is widely considered the last moment the CLARITY Act could advance from the Senate in the normal course of business. Section 604's developer protections remain in the merged text and are not the disputed provision, but every day the ethics fight drags is a day closer to the bill losing its 2026 runway entirely.

Update, August 7, 2026

The pre-recess floor vote is dead. Senate Majority Leader John Thune confirmed the chamber would not vote on the legislation before the recess, citing Democratic opposition, and said it would be prioritized when senators return next month.

Thune said, "The Dems are insistent on no Clarity vote,"

adding that "we're getting that queued up first thing when we come back."

The procedural picture is more specific than Thune's public statement suggests. Thune's office is telling crypto industry leaders that the Majority Leader still intends to file cloture on the motion to proceed to the CLARITY Act before lawmakers leave for August recess.

If he files before the Senate leaves town, lawmakers can hold the first procedural vote on the bill as soon as Tuesday, September 15; if he files after the Senate returns, the first vote could be held no earlier than Wednesday, September 16, under Senate procedure.

Thune declined to file the cloture motion required to start a floor vote, instead filing on the motion to proceed to the Protect College Sports Act, on a substitute amendment to the continuing-resolution vehicle, and on Todd Blanche's nomination for attorney general, with no corresponding filing for CLARITY.

The underlying vote math remains unsolved. Republicans have not yet secured the votes needed to invoke cloture, and disagreements remain over yield-related issues such as stablecoin rewards and over a bipartisan ethics provision.

According to Politico, a bipartisan counteroffer would force Trump and other officials to divest when a stake exceeds $1 million and represents 10% or more of a company's value. Prediction markets have absorbed the delay: Polymarket contracts on a 2026 signing trade near 15%, down from more than 70% in early May, across $5.16 million in volume. Section 604 and the developer safe harbor remain intact inside the bill, the ethics and yield disputes are the live blockages, and September is now the last realistic window before the fall calendar bends fully toward midterm positioning.

Update, August 8, 2026

The procedural dam broke overnight. Thune formally started the Senate floor process by filing cloture on the motion to proceed to H.R. 3633 early Saturday, shortly before the Senate adjourned for its summer recess.

The vote is expected after the Senate reconvenes on September 15, giving lawmakers several more weeks to resolve disagreements that prevented a deal before the August break.

Each cloture sequence in the Senate requires roughly a week of floor time; the CLARITY Act requires two.

The filing is meaningful but it does not change the headcount math. Republicans hold 53 seats, meaning roughly seven Democratic votes are needed to reach the 60-vote threshold, and the bill currently has none committed on the floor.

Democrats have signaled they intend to block the motion unless bipartisan consensus is reached on two sticking points: stablecoin yields and ethics rules for government officials with ties to digital assets. A new wrinkle on the Republican side has also surfaced: at least two Republican senators have stated they will vote against the bill if there are no changes to protect community banks from being hit by stablecoin yields.

The strategic logic behind filing without the votes in hand is preservation. Thune had indicated that the chamber lacked enough time to finish CLARITY Act consideration before the August break, and filing the motion preserves a faster path when senators return instead of restarting the procedure.

The key advance comes after the bill missed its window to get a vote before the Senate's summer break, leaving it in a long-shot position to get approval in September, though it would likely have been declared dead for 2026 without at least this first important movement. Thune himself confirmed the punt publicly, saying "we're getting that queued up first thing when we come back." Polymarket traders have cut the CLARITY Act's 2026 passage odds to just 23%.
