SEC Crypto Task Force member Hester Peirce has issued a stark warning to decentralized finance (DeFi) developers: onchain lending and vaults remain subject to federal securities laws, regardless of the underlying technology's decentralized architecture.

In a Wednesday blog post, Peirce insisted that builders should focus on the function and design of their tools rather than on how their technology might shield them from legal obligations. She urged developers to stop twisting and bending established laws to carve out special exceptions for crypto activities.

"You will have a painful fall," she cautioned.

Peirce's comments come as the SEC continues to re-examine its approach to digital asset regulation. In March, the agency issued guidance on the application of federal securities laws to protocol staking, airdrops, protocol mining, and wrapped crypto assets. That guidance also established a new taxonomy distinguishing between digital securities and crypto assets that may not qualify as securities. The guidance marked one of the most detailed SEC efforts to map traditional securities frameworks onto decentralized protocols, which collectively manage tens of billions of dollars in user deposits.

Although the SEC has adopted a more collaborative tone toward the crypto industry under its current leadership, Peirce emphasized that compliance expectations remain fully in force for products carrying out regulated financial functions. Her latest remarks reinforce a position she has maintained in previous speeches: blockchain innovation should not be confused with regulatory immunity. Known in the crypto community as "Crypto Mom" for her longstanding advocacy of clearer digital asset rules, Peirce has often argued for tailored regulation rather than blanket enforcement.

Peirce Acknowledges Differences in Vaults and Lending Platforms

The warning is particularly relevant for DeFi developers building yield-generating vaults, lending markets, and other automated investment products. These protocols — which include lending pools, liquidity vaults, and yield aggregators — allow users to deposit crypto assets that are then lent or deployed according to smart contract rules, often generating returns without a traditional financial intermediary. While many DeFi protocols rely on smart contracts rather than traditional intermediaries, Peirce indicated that regulators will assess the economic substance of a product rather than its decentralized architecture.

Peirce advised developers that if their activities involve securities, they need to work with the commission to remain compliant. Her comments build on earlier remarks about tokenized securities, in which she noted that such assets remain securities regardless of whether they are issued or traded on blockchain networks. A Reuters report from July 2025 similarly covered her position that tokenized securities do not escape SEC jurisdiction.

Those prior statements clarified that the SEC's jurisdiction is not diminished by the fact that securities trade on conventional systems or on blockchain technology. The same logic extends to crypto vaults, where users earn interest on deposited tokens. Vault governance spans a spectrum from full automation to full human management, and Peirce noted that these distinctions matter because managing the underlying asset or delegating investment powers could bring the securities in question under SEC regulation.

"For example, onchain loans, depending on the parties' motivations, the plan of distribution, and other relevant factors, can bear the hallmarks of notes that are securities," Peirce remarked. "Involvement in managing vaults and lending strategies also may implicate investment adviser issues."

She added that the SEC's approach is not "one size fits all." The commission will evaluate each crypto asset on its own merits to determine the applicability of the law. She also urged developers to consult the commission on the limits of regulation and to propose ways to modernize existing rules.

Peirce is planning to depart the SEC in November to join the faculty at Regent University School of Law. She has led the commission's Crypto Task Force since January 2025. Her departure means the agency will lose one of its most visible advocates for crypto regulatory clarity at a time when foundational rules for digital assets are still being shaped.

SEC and Congress Pursue Additional Regulatory Frameworks

Separately, the SEC is currently reviewing tokenization. Recent calls from Wall Street transfer agents have urged the agency to pay closer attention to tokens issued by companies themselves, as third-party tokens do not necessarily guarantee shareholders' rights. The review reflects broader institutional interest in moving traditional financial instruments onto blockchain infrastructure, a trend that major banks and asset managers have increasingly explored.

Meanwhile, the CLARITY Act is under consideration in Congress, aiming to clarify the respective regulatory jurisdictions of the SEC and the CFTC over digital assets. The divide between the two agencies — with the SEC overseeing securities and the CFTC regulating commodities and derivatives — has long created uncertainty about which rules apply to tokens that may fall somewhere in between. The legislation adds further momentum to the ongoing debate over U.S. cryptocurrency regulation.

Ultimately, Peirce's position leaves the door open for unregulated vaults and lending mechanisms, but she made clear that blockchain technology alone does not equate to securities compliance.
