Senate Republicans have released a 630-page update to the crypto market structure bill, adding proposed federal oversight for certain trading protocols while leaving major disagreements over ethics, stablecoin rewards and regulatory authority unresolved.
Senate Republicans have unveiled a revised version of the Clarity Act just days before a scheduled September 15 procedural vote that could determine whether the legislation advances to formal floor debate.
The updated bill contains new provisions addressing decentralized finance trading protocols, while also incorporating more than 114 provisions requested by Democratic senators, according to Sen. Cynthia Lummis.
Despite the changes, the revised legislation had not secured a public endorsement from a Democratic senator when it was released. Republicans hold 53 Senate seats, meaning at least 60 votes are required to move the bill forward.
The September 15 vote would not represent final passage. Instead, it would determine whether the Senate can begin debate and consider amendments.
What Changed in the New Clarity Act?
The revised legislation introduces a new category called a “non-decentralized finance trading protocol.”
The provision focuses on protocols where an individual or coordinated group retains direct or indirect authority to control or materially alter the system’s:
- Functions
- Operations
- Governance
- Consensus rules
Protocols falling within the proposed definition would be required to register with the Commodity Futures Trading Commission (CFTC).
The legislation directs the CFTC and Treasury Department to develop rules implementing the framework. That leaves regulators with significant responsibility for determining how the decentralization test would apply to different blockchain architectures and governance models.
The goal is to distinguish genuinely decentralized systems from projects that retain identifiable individuals or organizations capable of making substantial changes to their protocols.
DeFi Developers Could Face Greater Regulatory Responsibilities
The treatment of decentralized finance has been one of the most contentious issues surrounding the Clarity Act.
A central question has been whether developers, governance participants or interface operators should face financial regulatory obligations when they do not directly control or custody customers’ assets.
The latest version attempts to narrow the scope of its DeFi provisions by applying them to spot and cash digital commodity transactions.
Lummis said the clarification also addresses concerns raised by tribal governments about the potential interaction between the bill and prediction markets.
The revised text additionally provides clarification concerning certain digital asset activities by credit unions.
However, public summaries of the bill do not identify every modification contained in the 630-page document, leaving some details to be examined as lawmakers review the full text.
Ethics Rules Remain a Major Obstacle
One of the biggest unresolved political issues involves restrictions on government officials and digital assets.
The revised legislation retains language that would restrict public officials, government employees and their spouses from issuing or sponsoring digital assets.
The provision would primarily be enforced by the Justice Department and would expire in January 2029.
Democratic lawmakers have previously argued that the provision does not go far enough. Their concerns include the scope of the restrictions, enforcement mechanisms and the relatively short duration of the provision.
The issue has additional political significance because President Donald Trump and members of his family have financial connections to World Liberty Financial and the TRUMP memecoin.
Critics have argued that legislation establishing the rules for the cryptocurrency industry should include stronger safeguards concerning digital asset interests held by senior government officials.
A separate proposal developed by Democratic senators with Republican Sen. Thom Tillis included tougher ethics provisions, but major elements of that alternative were not incorporated into the September 10 revision, according to the supplied reporting.
Bipartisan Support Has Yet to Materialize
Lummis has described the revised legislation as the product of bipartisan negotiations and said Republicans incorporated more than 114 Democratic requests.
However, no Democratic senator had publicly committed to supporting the updated version at the time of its release.
That leaves the bill facing a significant mathematical challenge.
Republicans control 53 Senate seats, meaning they need at least seven Democratic votes if all 53 Republicans support the procedural motion.
The absence of publicly committed Democratic support therefore remains one of the most immediate hurdles facing the legislation.
Stablecoin Rewards Remain Contentious
Another major dispute concerns whether stablecoin issuers and other companies should be allowed to provide rewards to users.
Traditional banking groups argue that attractive stablecoin rewards could encourage customers to move money out of insured bank deposits.
That could reduce the pool of deposits available to banks for lending.
Crypto companies take a different position, arguing that transaction-related incentives are not necessarily equivalent to interest paid simply for maintaining a bank deposit.
Earlier versions of the legislation sought to distinguish between rewards based solely on holding stablecoins and incentives connected to activities such as payments or loyalty programs.
Banks Fear a Shift Away From Deposits
The debate has expanded beyond Washington as banking and cryptocurrency organizations campaign for support among senators.
The Independent Community Bankers of America has warned that substantial movement of funds from bank deposits into stablecoins could have consequences for community lending.
Reuters reported that the group arranged meetings between local bankers and senators during the August recess.
Meanwhile, crypto advocacy organization Stand With Crypto, backed by Coinbase, said its supporters contacted members of Congress nearly 50,000 times during August in support of crypto legislation.
The issue has also generated concerns among some Republicans.
Sens. James Lankford and Mike Rounds have questioned whether the legislation could enable certain digital assets to compete with conventional bank deposits.
Democrats have raised additional concerns involving money laundering, consumer protection and market integrity.
SEC and CFTC Responsibilities Would Be Redefined
At the center of the Clarity Act is an attempt to establish a clearer federal division of authority over digital assets.
The legislation would establish federal classifications for cryptocurrencies and determine which regulator oversees different types of activity.
Under the proposed framework, the CFTC would receive authority over spot markets involving assets classified as digital commodities, while the Securities and Exchange Commission (SEC) would continue overseeing assets and activities falling under securities law.
The new DeFi provisions would therefore add another layer to the proposed regulatory framework by establishing circumstances in which certain trading protocols would have to register with the CFTC.
September 15 Vote Is Only the Beginning
Senate Majority Leader John Thune has scheduled the procedural vote for September 15.
The vote requires 60 senators to support advancing the legislation.
If that threshold is reached, lawmakers could begin formal debate and propose amendments.
Potential areas for further changes include:
- DeFi registration requirements
- Stablecoin reward restrictions
- Government ethics provisions
- SEC and CFTC jurisdiction
- Consumer protection requirements
- Anti-money-laundering provisions
If fewer than 60 senators support the motion, the current version would not advance to floor debate unless lawmakers reach a new agreement and schedule another procedural vote.
House Approval Does Not Guarantee Final Passage
The House of Representatives has already passed its own version of the Clarity Act with bipartisan support.
However, the Senate is working from its own version, meaning any differences between the two bills would have to be resolved before identical legislation could reach the president.
That makes the Senate’s upcoming debate particularly important.
Even if the procedural vote succeeds, lawmakers would still need to negotiate amendments and ultimately reconcile the legislation with the House version.
Lummis Pushes for Crypto Legislation Before 2027
Sen. Lummis has continued advocating for passage of comprehensive cryptocurrency market structure legislation before the end of the congressional session.
She has argued that the United States needs a durable statutory framework for digital assets rather than relying primarily on regulatory policies that could change when administrations change.
The timing is particularly significant because lawmakers face the approaching November midterm elections, leaving a limited legislative window for completing major cryptocurrency legislation.
Lummis, who is not seeking another Senate term, is scheduled to leave Congress in January 2027.
The Senate Vote Could Set the Direction of US Crypto Regulation
The revised Clarity Act represents another attempt to establish a comprehensive regulatory framework for the US digital asset industry.
The addition of specific DeFi provisions could have significant consequences for blockchain protocols that maintain identifiable governance or upgrade authority.
At the same time, unresolved disagreements over stablecoin rewards, government ethics, consumer protections and regulatory jurisdiction could determine whether the legislation attracts enough bipartisan support.
The immediate question is therefore not whether the Clarity Act will become law.
It is whether lawmakers can secure the 60 votes needed on September 15 to begin the next stage of the legislative process.
If they do, the debate over how the United States regulates crypto markets, DeFi protocols and digital commodities will move from negotiations behind closed doors to a much more public Senate floor battle.
