The SEC wants new rules for onchain trading. Big shift coming.
Paul Atkins chairs the agency now, and he laid out plans on May 8 to build a framework covering trading systems that run on blockchains, broker-dealer work in crypto, and how vaults store digital assets. The agency sees hybrid platforms—ones mixing traditional finance rails with blockchain tech—as needing clearer treatment under securities law. Atkins said the SEC needs to figure out how these platforms fit into existing rules, or whether new ones make more sense. The move comes as more trading activity migrates onchain and custody providers handle billions in crypto assets without clear federal oversight. Regulators want to catch up.
Hybrid Platforms Face Compliance Pressure
Platforms operating between traditional finance and decentralized systems will probably see the biggest changes. The SEC’s looking at how to apply securities rules to systems that don’t fit neatly into old categories. A broker-dealer running settlement on Ethereum, for example, doesn’t match the template regulators used for Nasdaq or the NYSE. Same goes for custody. Crypto vaults don’t work like bank safe deposit boxes, and the SEC knows it. Atkins pointed out that the agency needs to adapt frameworks to accommodate blockchain’s unique traits while keeping investor protection intact. That’s a hard balance.
Hybrid platforms grew fast over the past few years. Some let users trade tokenized stocks. Others offer derivatives settled onchain. A few combine order books with automated market makers. The SEC didn’t write rules for any of that, so firms built products in a gray zone. Now the agency wants clarity, which could mean compliance costs rise sharply for platforms that assumed they could operate outside traditional broker-dealer registration. Atkins didn’t specify which platforms the SEC’s eyeing, but the industry’s watching closely.
What Comes Next
Details remain scarce. The SEC hasn’t published draft rules or a timeline for public comment. Atkins said the work’s in early stages, so don’t expect finalized regulations soon. The agency will probably consult with industry players, though past crypto rulemakings didn’t always involve much collaboration. Some firms worry the SEC will impose traditional broker-dealer requirements on decentralized protocols, which can’t really comply. Others think the agency will create a separate category for onchain systems, similar to how it treats alternative trading systems now. Unclear which path Atkins prefers.
The focus on crypto vaults matters a lot. Custody providers hold assets for exchanges, funds, and institutions. Right now, most operate under state money transmission licenses, not SEC oversight. If the agency decides vaults handling tokenized securities need federal registration, compliance costs jump. Smaller custody shops might exit the market. Bigger ones like Coinbase Custody or Anchorage already deal with regulators, so they’d adapt faster. But the SEC hasn’t said whether it plans to require registration or just wants reporting standards. Atkins mentioned oversight without getting specific.
Onchain trading rules could reshape how decentralized exchanges work. Platforms like Uniswap or Curve don’t have traditional order books or intermediaries. Users trade directly from wallets. The SEC’s struggled to fit these into securities law because there’s no obvious entity to regulate. Atkins hinted the agency’s thinking about how to bring these systems into compliance without breaking their core design. That’s tricky. If the SEC requires KYC for every wallet interacting with a protocol, it kills the decentralized model. If it doesn’t, bad actors keep using the platforms for fraud. No easy answers.
Broker-dealer rules complicate things further. Traditional broker-dealers register with the SEC, join FINRA, keep detailed records, and follow capital requirements. Onchain platforms don’t do any of that. Some don’t even have corporate entities—they’re just smart contracts governed by token holders. Atkins said the SEC’s considering how to apply broker-dealer frameworks to these setups, but he didn’t offer solutions. Industry lawyers think the agency might create a lighter registration tier for onchain intermediaries, similar to what it did for funding portals under crowdfunding rules. That’d let platforms operate legally without full broker-dealer burdens.
Clearing and settlement also got mentioned. Trades on traditional exchanges settle through clearinghouses like DTCC. Onchain trades settle instantly through smart contracts. The SEC wants to figure out if that instant settlement needs oversight, or if the code itself provides enough protection. Atkins noted that blockchain’s transparency and immutability change the risk profile compared to traditional systems. But he also said the agency can’t ignore settlement risk entirely, especially if tokenized securities start trading at scale. The SEC might require audit trails or real-time reporting even for onchain settlement.
Stakeholders will need to track this closely. The crypto industry’s been waiting for clear rules since 2017, and the SEC’s moved slowly. Atkins seems more willing to engage than past chairs, but that doesn’t guarantee favorable rules. Some firms might face registration requirements they can’t meet. Others could get carve-outs if they lobby effectively. The regulatory outcome will shape which business models survive and which platforms shut down or move offshore. No timeline yet, so the waiting continues.
Frequently Asked Questions
What specific platforms is the SEC planning to regulate?
The SEC hasn’t named specific platforms yet. Atkins said the agency’s developing rules for hybrid systems that combine traditional and blockchain-based trading, but details on which firms face new requirements remain undisclosed.
When will the SEC finalize these onchain trading rules?
No timeline has been announced. Atkins said the work’s in preliminary stages, so draft rules and public comment periods likely won’t happen soon.
