DeFi Firms Press SEC for Binding Broker Rules on Non-Custodial Interfaces

Major DeFi players are asking the SEC to turn its new guidance on non-custodial user interfaces into formal, binding broker rules — and fast. Their message is blunt: if a neutral front end isn’t a broker, it shouldn’t be left hanging on a temporary staff interpretation that can be reversed by the next round of regulators with a taste for paperwork and punishment.

• DeFi firms want formal SEC broker rules
• Neutral self-custody front ends shouldn’t be treated like brokers
• Vague language could hit validators, RPCs, oracles, and cloud providers
• Congress is stalled, so SEC rulemaking looks like the only near-term path

A coalition including the DeFi Education Fund, Aave Labs, Uniswap Labs, Paradigm, Andreessen Horowitz, and other crypto industry participants has urged the SEC to convert its April 13 staff guidance into formal notice-and-comment rulemaking, according to recent industry reporting. The guidance came from the SEC Division of Trading and Markets and focuses on when crypto asset front ends must register as brokers.

For readers new to the terminology: a non-custodial user interface is basically a website or app that helps users interact with a blockchain protocol without ever taking control of their funds. Think storefront, not vault. The interface may make the system usable, but it doesn’t hold your keys or decide what happens to your assets. That difference matters a lot when regulators start waving around the word broker.

A broker is normally a middleman who arranges trades for clients. The industry’s argument is simple: a neutral front end that merely helps users submit blockchain transactions is not acting like a traditional broker-dealer. It’s software. It’s infrastructure. It’s not your financial advisor, and it’s not sitting in the middle skimming off the top like some greasy toll booth operator in a silk tie.

The SEC’s guidance does mark a real shift. Under its five-year no-action framework for Covered User Interface Providers, certain providers can operate without broker registration if they meet 12 conditions. The framework also allows some transaction-based fees, but only if compensation is flat, objective, and agnostic to product or venue. In plain English: you can charge in a limited, rule-based way, but you don’t get to juice the model by steering users to a favorite trade path. And yes, payment for order flow remains banned — meaning platforms still can’t get paid for routing user trades to a particular venue, a setup that can create ugly conflicts of interest.

That said, the coalition isn’t celebrating and moving on. Its core complaint is that staff guidance is not the same thing as a binding rule. A memo can be reinterpreted, narrowed, or tossed in the bin later. That’s no way to build serious infrastructure in the United States, especially when the industry is being asked to plan years ahead under a legal framework that changes with every new political mood swing.

The coalition wants a more permanent regulatory approach through formal SEC rulemaking, because only Commission-level action can provide lasting legal certainty. The guidance itself is temporary, and if the Commission does nothing, the framework can be withdrawn in 2031. That’s not exactly the sort of horizon that makes builders want to pour capital into U.S. DeFi infrastructure. You don’t build the future of finance on regulatory temporary vibes.

There’s also a bigger problem lurking under the surface: vague language can spread like mold. The coalition warns that unclear rules could sweep up infrastructure that has nothing to do with brokerage activity, including validators, RPC/API providers, oracle networks, and cloud services. These are the plumbing of blockchain systems, not shady intermediaries trying to route users into a trap.

For those less familiar:

• Validators help secure and confirm blockchain transactions.
• RPC/API providers let wallets and apps communicate with blockchains.
• Oracle networks bring outside data onto chains.
• Cloud infrastructure hosts the servers many apps depend on.

None of those are brokers in the conventional sense. They don’t hold customer funds, they don’t make discretionary trade decisions, and they’re not brokering trades like a Wall Street firm. If the SEC’s broker definition gets stretched far enough to catch them anyway, the likely result is not investor protection — it’s a regulatory gut punch that pushes core U.S. infrastructure offshore.

“Absent clear, technology-neutral rules, future staff or Commissions could reinterpret the broker definition in ways that chill innovation and push core U.S. infrastructure offshore”

That line gets to the heart of the fight. This is not just about one staff statement or one class of front ends. It’s about whether old securities-law language can be applied sensibly to decentralized systems without turning every useful piece of software into a compliance liability. The SEC’s job is to protect investors and stop firms from disguising themselves as harmless code while functioning like financial intermediaries. Fair enough. But there’s a line between guarding the public and treating every protocol layer like it’s one bad actor in a fake mustache.

The coalition’s position is not that the SEC got nothing right. It explicitly accepts the idea that neutral, self-custodial front ends should not be swept into broker registration. That matters. The industry is not asking for a pass to build a lawless casino. It’s asking for a regulatory framework that can tell the difference between actual financial intermediation and software that simply converts user instructions into blockchain-legible commands.

That exact wording shows up in the broader discussion around the guidance, and it’s important because it reflects how these tools actually work. A self-custodial interface may help a user interact with a protocol, but it doesn’t custody assets. It doesn’t necessarily direct trades. It doesn’t magically become a broker just because it makes a decentralized protocol easier to use. If the law can’t distinguish the front end from the machine behind it, then the law needs tightening — not a bigger hammer.

The April 13 guidance has been treated as a significant first step, including by legal firms such as Sidley, Jones Day, and Deloitte, which framed it as a useful path forward. But that support came with an important caveat: the guidance is useful for broker-dealer questions, not for the broader mess of crypto compliance. That’s the trap here. A step forward is still just a step if the foundation underneath can be pulled away later.

The political backdrop only makes the issue more urgent. The CLARITY Act, a crypto market structure bill that could settle a lot of these questions, is stalled in the Senate Banking Committee. Senator Bernie Moreno has set a hard end-of-May deadline, putting pressure on lawmakers to move, but deadlines in Washington often function more like decorative signage than actual constraints. Until Congress stops dragging its feet, the SEC remains the main battlefield for defining what counts as a broker in crypto.

That’s why this isn’t just another policy letter from industry lobbyists looking for a softer touch. It’s a warning that if the U.S. keeps relying on temporary staff-level guidance instead of durable rules, the people building decentralized infrastructure will take the hint and build somewhere else. And once those engineers, validators, app teams, and infra providers leave, good luck begging them back with a handful of committee hearings and a new round of slogans.

Hester Peirce, one of the SEC’s most crypto-friendly commissioners, has long argued for a more durable and technology-neutral approach. That framing lines up neatly with what the coalition is asking for here: rules that are clear, predictable, and hard to reinterpret into oblivion later. The industry doesn’t want special treatment. It wants the government to stop pretending that all software touching a blockchain is secretly a broker in a hoodie.

What the SEC guidance says in practice

• Some non-custodial front ends can avoid broker registration if they meet specific conditions.
• Covered User Interface Providers get a five-year no-action framework.
• Fees are allowed only if they are flat, objective, and not tied to product favoritism or venue routing.
• Payment for order flow is still prohibited.
• The framework is temporary and can be withdrawn in 2031 if the Commission doesn’t make it permanent.

Why DeFi builders are pushing back

Because temporary guidance is not the same thing as legal certainty. A staff statement can help today and vanish tomorrow. A binding rule, created through notice-and-comment rulemaking, is harder to reverse and gives builders something solid to design around. That matters for developers, investors, exchanges, wallet providers, and users who don’t want to wake up one morning and discover their favorite interface has been relabeled as a regulated broker because some lawyer decided the vibe changed.

Why users should care

If regulators overreach and catch neutral infrastructure in the net, the damage won’t stop at startup balance sheets. Users could end up with fewer access points, more compliance friction, and more reasons to rely on offshore products that are harder for U.S. law to touch. That’s a terrible trade: less transparency, less consumer protection, and more power concentrated in places where the average user gets fewer rights and fewer remedies.

Why the SEC still believes oversight is justified

The regulator’s likely view is not hard to understand. Interfaces can influence how orders are submitted, how fees are structured, and how users access financial products. If a front end materially shapes trade execution or helps route activity in a way that resembles brokerage, the SEC will argue oversight is appropriate. That’s the core tension: protecting users without forcing a 20th-century legal template onto 21st-century software.

Key questions and takeaways

What do DeFi heavyweights want from the SEC?
They want the staff guidance on non-custodial user interfaces turned into formal broker rules through notice-and-comment rulemaking.

Why isn’t staff guidance enough?
Because staff guidance can be changed or withdrawn later. Formal Commission rules would give builders more durable regulatory certainty.

What could get caught in the crossfire?
Validators, RPC/API providers, oracle networks, cloud infrastructure, and other neutral parts of blockchain infrastructure if the broker definition is stretched too far.

What does the SEC’s current framework allow?
Some Covered User Interface Providers can avoid broker registration if they satisfy 12 conditions, with limited transaction-based fees allowed under strict terms.

What is still banned?
Payment for order flow remains banned under the guidance.

Why does the CLARITY Act matter?
Because it is stalled in Congress, leaving SEC rulemaking as the most realistic near-term path to legal clarity for U.S. DeFi infrastructure.

Is the SEC guidance a win for crypto?
Yes, but only partially. It’s a meaningful step for non-custodial front ends, but it still leaves too much uncertainty for the broader DeFi stack.

What is the real fight here?
Whether decentralized software and neutral infrastructure should be treated like old-school financial intermediaries just because they help users interact with blockchain systems.

The bottom line is simple: DeFi builders are willing to work with the SEC, but they’re not interested in constructing the future of finance on a regulatory sticky note. They want rules that are clear, technology-neutral, and durable enough to survive the next bureaucratic mood swing. That’s not radical. That’s basic sanity.
