The CLARITY Act changed again this week, just five days ahead of a crucial Senate procedural vote on September 10. The new 630-page draft includes updated rules for crypto protocols that describe themselves as decentralized but continue to be controlled by a company, founder, or coordinated group. Those platforms may be forced to register with the Commodity Futures Trading Commission (CFTC).
The bill’s effect on genuinely decentralized DeFi is significantly more nuanced. The CLARITY Act preserves protections for non-custodial software development and self-custody while trying to draw a clearer legal line between autonomous protocols and centralized businesses operating under DeFi branding. That distinction may well be the most consequential part of the new CLARITY Act.

What Changed in the Latest CLARITY Act?
The September revision makes three important changes related to DeFi.
First, it includes clearer rules for what the bill calls a “non-decentralized finance trading protocol.” If an individual or coordinated group can control or materially alter a protocol, then the project may no longer receive the same treatment as genuinely decentralized DeFi.
Second, those controlled protocols could be required to register with the CFTC. The bill also instructs the CFTC and Treasury to develop more detailed rules for them.
Finally, the new CLARITY Act narrows its DeFi provisions to spot and cash digital commodity transactions. Senator Cynthia Lummis said this was done in part to address concerns that the previous language could impact prediction markets.
The revision therefore does not abandon DeFi’s carve-outs. It tries to further protect them from being exploited by centralized businesses.

What Is a “Non-Decentralized Finance Trading Protocol”?
This wording is the biggest change for DeFi.
Under the revised language, a protocol would count as non-decentralized when a person or group acting together has direct or indirect authority to control or materially alter its functionality, operations, or rules.
That creates a control test rather than simply determining if software runs through smart contracts.
A project could call itself decentralized while using a DAO and issuing governance tokens and executing trades onchain but retain meaningful centralized control. The CLARITY Act is increasingly focused on seeing through that.
The practical question then becomes: who can actually change the system?
Why the Control Test Matters for DeFi
Many DeFi protocols exist somewhere between complete decentralization and a traditional centralized exchange.
A development company may retain upgrade keys. A small multisig may control emergency functions. Token governance may technically vote on proposals while a small group controls most meaningful decisions. A team may be able to change fees, halt contracts, replace components, or alter access to the protocol.
None of these necessarily make a project “controlled” under the new guidelines. But they may become pertinent in determining whether anyone has the power to materially control the system.
This should create a strong incentive for DeFi projects to demonstrate that their decentralization is real.
Could Controlled DeFi Platforms Have to Register With the CFTC?
Yes.
The revised CLARITY Act would establish a regulatory basis for non-decentralized finance trading protocols under CFTC oversight.
The CFTC and Treasury will then be tasked with writing tailored rules on how those requirements apply.
That matters as the bill seeks to prevent a centralized trading business from merely avoiding exchange regulation through using smart contracts.
For genuinely decentralized protocols, there may be no conventional operator capable of registering. For a protocol effectively controlled by a company or identifiable team, Congress is signaling that someone can still be held responsible.
What Does the CLARITY Act Mean for Truly Decentralized DeFi?
The bill remains considerably more favorable towards genuinely decentralized software.
Its broader structure protects developers and infrastructure providers who publish or maintain software without taking control of customer assets. It also protects peer-to-peer transactions and the right of users to keep digital assets in self-hosted wallets.
That means writing smart-contract code does not automatically make a developer a financial intermediary.
This is an important distinction for open-source DeFi.
Under the CLARITY Act, regulation is increasingly supposed to follow control and intermediation rather than software publication itself.

Does the CLARITY Act Protect Crypto Developers?
Yes, although the protections are not unlimited.
The bill incorporates principles from the Blockchain Regulatory Certainty Act. Developers who create or maintain blockchain software without controlling customer funds would generally not be treated as money transmitters simply because others use their code.
The legislation also directs regulators to distinguish software development from running a financial intermediary.
Fraud, sanctions violations, or actually controlling a trading business would not be protected simply because smart contracts are involved.
For developers, the key question therefore shifts from “Did you write the code?” towards “What do you actually control?”
What Happens to Self-Custody?
The CLARITY Act continues to protect self-custody.
Users would retain the ability to hold digital assets directly rather than being forced to use a regulated custodian or exchange.
That protection matters for DeFi because self hosted wallets are the normal way users interact directly with decentralized applications.
At the same time, centralized companies connecting users to DeFi would still have to fulfill compliance requirements. Treasury would also have the option to issue risk-based guidance covering how regulated intermediaries interact with self-hosted wallets.
The bill therefore tries to preserve direct wallet ownership without making every gateway into DeFi regulation-free.
What Happens to DeFi Front Ends and Development Companies?
This is where the new language could create difficult cases.
A decentralized smart contract may operate autonomously while a company controls the main interface through which users access it. Another protocol may have decentralized governance but retain emergency upgrade powers. A foundation could have no custody over user funds but still exercise substantial influence over development.
The latest CLARITY Act does not reduce those situations to a simple checklist.
Instead, regulators would have to determine whether the relevant person or group has enough authority to control or materially alter the trading protocol.
That means governance design, upgrade mechanisms, admin keys, ownership structure, and operational control could matter much more than the “DeFi” label itself.
Why Were Prediction Markets Added to the DeFi Fight?
The September draft also narrows the DeFi provisions so they only apply to spot and cash digital commodity transactions.
The change responds partly to concerns from tribal governments that broader language could impact prediction markets.
Prediction platforms can involve event contracts rather than simple purchases and sales of crypto assets. Their legal treatment already overlaps with gambling, derivatives, commodity regulation, and tribal gaming interests.
By narrowing the DeFi provisions, lawmakers are trying to prevent the CLARITY Act from accidentally re-writing prediction-market rules through a section primarily designed for decentralized crypto trading.

What Does the Bill Mean for the SEC and CFTC?
The larger purpose of the CLARITY Act remains dividing responsibility for crypto between the Securities and Exchange Commission (SEC) and CFTC.
The CFTC would become the principal regulator for digital commodity spot markets and registered digital commodity intermediaries.
The SEC would retain authority over securities and certain token fundraising arrangements that fall within securities law.
That division is especially important for DeFi because protocols may support dozens or hundreds of assets with different legal characteristics.
The bill also creates mechanisms for greater SEC-CFTC coordination instead of forcing projects to guess which regulator will claim jurisdiction after launch.
What About AML and Sanctions Rules?
The bill does not create a blanket AML requirement for every smart contract. Instead, it focuses much of its compliance framework on identifiable intermediaries and controlled protocols.
Centralized digital asset firms interacting with DeFi can face risk-management, sanctions, and illicit-finance obligations. Treasury would also receive additional powers and rulemaking responsibilities.
This remains one of the most disputed sections of the CLARITY Act.
Supporters argue that the framework targets businesses and people who can realistically implement compliance controls without imposing impossible obligations on autonomous software.
Critics, including Senate Banking Committee Democrats, argue that the DeFi exemptions remain broad enough to create loopholes for mixers, sanctions evasion, and illicit finance.
Why DeFi Mixers Remain Controversial
Decentralized mixers present the toughest version of the problem.
If nobody operates a protocol and nobody controls customer funds, conventional financial regulation becomes difficult to apply. Yet the same infrastructure can be used to obscure transactions connected with hacks, sanctions evasion, or criminal activity.
Senate Republicans argue that the CLARITY Act preserves legitimate privacy technology while giving Treasury and law enforcement targeted tools against illicit activity.
Democratic critics argue that the latest bill still weakens authorities against decentralized mixers.
The September revision does not completely resolve that disagreement.
What Has Not Changed in the New CLARITY Act?
Not every contentious issue is resolved.
Most notably, the latest draft did not make significant changes to its ethics provisions covering crypto activity by government officials.
That remains a major obstacle to Democratic support.
The dispute over stablecoin rewards and their impact on bank deposits also continues to influence negotiations between the crypto and banking industries.
These issues matter for DeFi because the Senate needs 60 votes to move the legislation forward. Technical agreement on decentralized protocols does not guarantee that the wider bill can pass.
Will the CLARITY Act Pass the Senate?
The first major test comes September 15 at 2:15 p.m. ET, when the Senate is scheduled to vote on cloture on the motion to proceed to H.R. 3633.
That is not a final vote on passage. It is a procedural vote, determining whether the Senate can move towards debating the bill. Sixty votes are required.
Republicans hold 53 seats, so the CLARITY Act cannot clear that threshold without support from Democrats or independents.
The Senate Banking Committee previously approved the legislation 15–9 in May with some bipartisan support. But the latest September text had not yet secured a broader bipartisan agreement when it was released.
What Should DeFi Projects Watch Next?
For DeFi builders, the vote on September 15 matters, but the eventual regulatory definitions matter even more.
The biggest question is how regulators will interpret “control.”
A protocol with immutable contracts and no privileged administrator does not pose as much risk against Coinbase or Binance. The difficult cases are protocols with upgradeable contracts, foundations, concentrated governance, front-end operators, emergency councils, or development teams that still retain important powers.
If the CLARITY Act becomes law, then those structures may determine whether a project receives decentralized-software protections or becomes a regulated intermediary.
Final Verdict: What the New CLARITY Act Means for DeFi
The new CLARITY Act is neither a blanket DeFi exemption nor an attempt to regulate every developer like an exchange.
Its emerging compromise is more specific: decentralized software receives more protections, but centralized control cannot hide behind smart contracts and a DAO.
That could be a major win for permissionless protocols and open source developers.
It could force many projects to answer a question that the industry has spent years avoiding: how decentralized are they really?
The September 15 Senate vote will determine whether such a framework gets a chance to move forward—or whether U.S. DeFi regulation remains in the hands of the SEC, CFTC, Treasury, courts, and future administrations.
FAQ
What Is the CLARITY Act?
The CLARITY Act is U.S. crypto market-structure legislation designed to divide regulatory responsibility between the SEC and CFTC and establish federal rules for digital asset markets.
What Changed in the CLARITY Act in September 2026?
The September 10 draft added clearer rules for “non-decentralized finance trading protocols,” potentially requiring controlled DeFi platforms to register with the CFTC. It also narrowed DeFi provisions to spot and cash digital commodity transactions.
Does the CLARITY Act Ban DeFi?
No. The bill explicitly protects genuinely decentralized software, non-custodial developers, peer-to-peer transactions, and self-custody while creating rules for platforms that retain meaningful centralized control.
Will DeFi Developers Have to Register With the CFTC?
Not simply because they write or maintain code. Registration would depend on whether a person or group actually controls a covered trading protocol and on the detailed rules that regulators develop.
When Is the Next CLARITY Act Vote?
The Senate is scheduled to hold a cloture vote on the motion to proceed to H.R. 3633 on September 15, 2026, at 2:15 p.m. ET. Sixty votes are required.
