SEC sets rules for DeFi interfaces

TLDR

The SEC has issued temporary guidance that lets some DeFi and wallet interfaces avoid US broker-dealer registration if they stay neutral, non-custodial, and highly transparent.

1. The SEC created a five-year safe harbor for Covered User Interfaces - DeFi front-ends, wallet apps, and aggregators tied to self-custodial wallets - that meet strict conditions.
2. To qualify, interfaces cannot hold funds, route or execute orders, or give investment advice, and must use fixed neutral fees and objective sorting of venues with detailed disclosures.
3. This is staff guidance, not permanent law, so public comments, future rulemaking, and how the SEC treats DeFi protocols and tokens themselves remain key things to watch.

Deep Dive

1. What The SEC Actually Did

The SECs Division of Trading and Markets issued a staff statement on 13 Apr 2026 describing when Covered User Interface Providers can facilitate crypto asset securities trades without registering as broker-dealers, for up to five years.[^1]

Covered user interfaces are websites, wallet extensions, or mobile apps that help users prepare on-chain transactions from self-custodial wallets, including DeFi front-ends and aggregators.[^2]

The statement is effectively a conditional no-enforcement framework rather than a full rulemaking, and it is scheduled to expire in 2031 unless the Commission acts earlier.[^3]

2. Key Conditions For DeFi And Wallet UIs

To avoid broker-dealer registration, an interface must not execute or settle trades, hold or control user funds or keys, route orders, arrange financing, or solicit specific transactions.[^1][^4]

It must remain neutral: charging fixed or flat fees that do not vary by asset, venue, or route, avoiding best price style endorsements, and using only objective criteria such as price or speed when listing execution options.[^2][^3]

Providers must disclose all fees and fee formulas, conflicts of interest, MEV risks, cybersecurity practices, connected venues and affiliations, and clearly state that they are not SEC-registered for these activities.[^3][^4]

3. Open Questions And What To Watch Next

The guidance explicitly does not address whether particular tokens are securities or how other regimes (like money transmitter or AML rules) apply, so broader regulatory risk remains.[^4]

It is an interim staff position, not a Commission rule, and can be withdrawn or revised; Commissioner Hester Peirce has already called for permanent, tailored broker rules for crypto interfaces and wallets.[^5]

The SEC is soliciting public comments, and how developers adapt designs, plus whether Congress advances a broader market structure bill, will determine how durable this DeFi interface path really is.[^2][^5]

Conclusion

The SECs new DeFi interface guidance carves out a narrow space where non-custodial, neutral front-ends can operate without broker-dealer registration, reducing one major compliance overhang.

At the same time, it leaves core questions about token classification and protocol-level liability unresolved, so DeFi risk shifts from any UI might be a broker toward stay within strict UI guardrails while waiting for fuller rulemaking.
