Senate Revises Clarity Act, Adds DeFi Rules Ahead of Vote

Senate GOP releases revised 630‑page Clarity Act before procedural vote

Five days before a scheduled September 15 procedural vote, Senate Republicans circulated a revised 630‑page draft of the Clarity Act that introduces new federal rules for certain decentralized finance (DeFi) trading protocols. The updated text, disclosed on Sept. 10, aims to define and regulate protocols that federal lawmakers determine are not sufficiently decentralized and would require registration with the Commodity Futures Trading Commission (CFTC).

The procedural vote is a threshold decision: 60 senators must back the motion to move the bill into formal debate, where amendments can be offered and the legislative text can be negotiated further. With Republicans holding 53 Senate seats, GOP leaders need some Democratic support to clear the cloture hurdle and begin consideration of this landmark crypto market structure bill.

Key takeaways

• The revised draft creates a new legal category labeled a “non‑decentralized finance trading protocol,” targeting systems where individuals or coordinated groups retain practical control.
• Protocols meeting that definition would be required to register with the CFTC; the bill tasks the CFTC and Treasury with designing implementing rules.
• Sponsors say more than 114 provisions requested by Democratic senators were folded into the new draft, but no Democratic senator had publicly endorsed the text at publication.
• An ethics provision restricting public officials and their spouses from issuing or sponsoring digital assets remains in place, enforced primarily by the Department of Justice and set to expire in January 2029.
• The bill confines its DeFi language to spot and cash transactions in digital commodities and reallocates regulatory authority between the CFTC and the Securities and Exchange Commission (SEC).

Defining controlled protocols: what the new language does

The updated Clarity Act introduces a statutory test to distinguish genuinely permissionless systems from projects that are marketed as decentralized but retain identifiable management or upgrade authority. Under the draft’s proposed definition, a "non‑decentralized finance trading protocol" would include situations where one or more people or coordinated groups have direct or indirect power to materially change a protocol’s operations, functions or consensus rules.

If a protocol meets that standard, it would fall under CFTC registration rules and oversight. The bill directs the CFTC and the Treasury Department to write implementing guidance, acknowledging the technical and governance complexities that separate truly decentralized networks from protocols with human or organizational control points.

This approach attempts to align regulatory treatment with economic reality: where a protocol is effectively controlled by identifiable actors, the law would treat it more like an exchange or trading platform rather than an independent, permissionless network.

Why control debates matter for DeFi

Questions about who controls a blockchain or DeFi application have been central to the congressional debate. Lawmakers and stakeholders have disputed whether roles such as software developers, interface operators, and governance token holders should face financial compliance duties when they do not custody user assets. The new definition addresses one aspect of that debate by targeting practical control, but it leaves many operational details to regulators.

Limiting the provisions to spot and cash transactions for digital commodities narrows the bill’s footprint, but it does not resolve broader disputes regarding custody, liability, or whether nodes, maintainers and governance participants could be treated as regulated entities.

Ethics language remains a sticking point for Democrats

The revised bill keeps an ethics restriction barring public officials, government employees and their spouses from issuing or sponsoring digital assets. Enforcement authority would rest primarily with the Department of Justice, and the restriction would sunset in January 2029. President Donald Trump previously accepted an ethics clause, but many Democrats have criticized the provision as too weak, citing its limited scope, short expiration, and narrow enforcement mechanism.

Democratic senators had proposed a stronger alternative with Republican Sen. Thom Tillis that included more stringent conflict‑of‑interest controls. The Sept. 10 draft did not adopt major elements of that proposal, and at the time of publication no Democratic senator had publicly committed to supporting the revised bill. The absence of bipartisan backing leaves Republicans short of the 60 votes required to proceed if the chamber lines up by party.

Political and reputational context

The ethics debate is politically charged because of public scrutiny over senior officials’ financial ties, including high‑profile memecoin and token projects. Critics argue that meaningful crypto market legislation should include robust conflict‑of‑interest rules to prevent officials from directly benefiting from regulatory changes they help shape.

Stablecoin rewards, bank deposits and industry lobbying

Another unresolved issue in the Clarity Act concerns rewards paid on stablecoin balances. Banking groups warn that reward programs resembling interest could encourage customers to shift funds out of federally insured bank deposits, weakening deposit bases that lenders use to underwrite loans. Crypto firms counter that many stablecoin rewards are transaction‑based or part of loyalty programs, and therefore differ materially from deposit interest.

Earlier versions of the bill tried to strike a middle ground by barring payments solely for holding stablecoins while allowing rewards tied to payments, loyalty incentives and other qualifying activities. Nevertheless, the dispute has triggered active lobbying: local bankers met with senators during recess, while industry groups such as Stand With Crypto — backed by Coinbase and others — organized outreach campaigns and public advocacy across multiple states.

Senators from both parties have expressed concerns. Some Republicans and several Democrats worry the bill could allow certain tokens or programs to compete too closely with traditional deposit products, raising financial stability, consumer protection and bank regulatory issues.

Regulatory allocation: CFTC vs. SEC

The Clarity Act would create statutory classifications for digital assets and split oversight between the CFTC and the SEC. Under the draft, the CFTC would assume authority over spot markets for assets designated as digital commodities, while the SEC would retain jurisdiction over securities. Sponsors say this allocation delivers clearer, more durable governance for digital asset markets than agency rulemaking alone.

However, the dividing lines between commodities and securities remain legally and technically complex. The bill’s passage would not end litigation or regulatory friction, but it could reshape the operating environment for exchanges, custodians, and DeFi platforms by clarifying which federal regulator oversees which activity.

Industry implications

If enacted, the Clarity Act would force businesses that operate or interact with trading protocols to reassess compliance frameworks, potentially registering as trading platforms or changing governance models to avoid falling into the CFTC registration category. Developers, governance participants, and interface providers may need to adopt new operational safeguards to limit perceived control, or else face registration and oversight requirements.

What happens next: the Sept. 15 procedural vote and beyond

Senate Majority Leader John Thune scheduled the procedural vote for Sept. 15, immediately after senators return from recess. A successful 60‑vote result would move the Clarity Act into floor debate and open it up to amendments addressing the ethics language, stablecoin rules, DeFi definitions, or the SEC‑CFTC jurisdictional split.

If the motion fails to reach 60 votes, Senate leaders would either renegotiate terms to attract additional support or delay further action. Time is constrained by the upcoming November midterm elections, and many congressional staffers and industry observers see the remaining 2026 legislative calendar as a critical — and possibly final — window to pass comprehensive federal crypto legislation this year.

Sen. Lummis’ position and political timetable

Sen. Cynthia Lummis, a principal sponsor of the measure, said the revision incorporated more than 114 items requested by Democratic senators and argued the bill would create a durable statutory framework that future administrations could not easily overturn through agency rulemaking. Lummis is not seeking re‑election and will leave the Senate in January 2027; she has urged colleagues to act so the U.S. sets its own crypto rules rather than ceding influence to other jurisdictions such as Singapore or the United Arab Emirates.

Bottom line for crypto markets

The Clarity Act’s revised text represents a major step toward congressional regulation of digital asset markets, but the path to passage remains uncertain. The new definition of controlled DeFi protocols and the CFTC registration requirement would materially affect how trading platforms and some DeFi projects are structured and governed. Stablecoin rules, ethics provisions and the SEC‑CFTC split are unresolved flashpoints that could determine whether the bill secures the bipartisan backing needed to advance.

Market participants should monitor the Sept. 15 procedural vote closely. A successful cloture vote would initiate a high‑stakes floor debate with amendment votes that could reshape the final bill — and, if enacted, alter the regulatory landscape for decentralized finance, stablecoins, exchanges and custodial services across the United States.
