Letter Regarding Wallet Providers and Broker Dealer Regulation
Custody, Safe Harbor, Security Status, Tokenization, Trading
  • Wallet providers performing broker-dealer functions for tokenized securities must register under the Exchange Act; exemptions or no-action relief are inappropriate as they undermine investor protection and market integrity.
  • Clear regulatory distinctions are required between true non-custodial wallet services and models involving custody or safekeeping, as the latter may trigger broker-dealer or other regulatory obligations.
  • Regulatory clarity should be achieved through durable, notice-and-comment rulemaking that defines when wallet providers are or are not brokers, rather than through ad hoc exemptions or safe harbors.

Custody, Public Offerings, Safe Harbor, Security Status, Tokenization, Trading
  • The SEC should mandate DTCC cooperation to enable near real-time movement of registered ownership between direct and intermediated holding, creating a level playing field for tokenized securities.
  • Infrastructure reform is necessary to remove regulatory and market barriers to direct holding and self-custody, ensuring benefits equivalent to intermediated accounts for direct holders.
  • The SEC should request proposals for a reformed infrastructure and clarify broker-dealer authority to execute transfers of directly held securities for trading in traditional markets.

Re: Request for Information Regarding National Securities Exchanges and Alternative Trading Systems Trading Crypto Assets — Request No. 16
Custody, Regulatory Sandbox, RFI Responses, Safe Harbor, Tokenization, Trading
  • The SEC should adopt a technology-neutral framework that distinguishes true intermediaries (those holding funds or controlling execution) from developers of non-custodial, non-discretionary software tools.
  • Interpretive guidance should confirm that publishing or maintaining non-custodial software (wallets, smart contracts, passive interfaces) does not constitute operating an exchange, clearing agency, or effecting transactions for others.
  • The definition of “exchange” should exclude non-custodial, non-discretionary software that does not perform marketplace functions, ensuring communication layers and read-only tools remain outside regulatory scope.

Re: Tokenized U.S. Equity Securities & DeFi Trading Protocols
Custody, Regulatory Sandbox, RFI Responses, Safe Harbor, Security Status, Tokenization, Trading
  • The SEC should apply existing statutory definitions of “exchange,” “broker,” and “dealer” to DeFi participants and assess compliance under the Securities Exchange Act of 1934.
  • The SEC lacks authority and policy basis to grant broad exemptive relief from these definitions, as doing so would undermine investor protections and market resiliency measures.
  • Instead of disapplying the regulatory framework, the SEC should conduct rule-by-rule analysis and address impediments through notice-and-comment rulemaking to preserve investor protections.

  • All pilot participants—including broker-dealers, custodians, and technology providers—must undergo structured conformance testing and certification to validate adherence to operational playbooks and reference implementation profiles. Certification is a prerequisite for participation and includes baseline and enhanced tiers with annual recertification requirements.
  • The pilot establishes a multi-tiered governance framework, including a Pilot Steering Committee and Change Control Board, with defined authority over standards evolution, incident coordination, and regulatory engagement. Supervisory access is governed by tiered models (Tier 0–2) to ensure due process, privacy, and non-surveillance principles.
  • The Operationalization Track is strictly limited to U.S. domestic institutional markets and does not create new legal obligations beyond those required for pilot participation. It complements existing federal securities laws and SRO rules, focusing on operational specificity for tokenized securities without replacing existing infrastructure or extending to retail or cross-border markets.

Technical Risk Analysis of Privacy Preserving Assets & Complex Financial Technology
Custody, RFI Responses, Safe Harbor, Security Status
  • Zcash and Aleo rely on zkSNARKs requiring a “trusted setup,” which introduces a permanent trust assumption. If the setup’s entropy (“toxic waste”) is not securely destroyed, it could allow undetectable token counterfeiting, undermining supply integrity.
  • Zcash’s opt-in privacy model results in most transactions being transparent, enabling deanonymization through statistical analysis. This undermines its claim to privacy-preserving status and exposes users to surveillance risks.
  • Aleo’s programmable privacy increases protocol complexity, which has led to real-world data leaks (e.g., unencrypted KYC data). This complexity heightens the likelihood of implementation flaws, expanding the attack surface and compromising user privacy.

RE: Additional Input to the SEC Crypto Task Force on the Regulation of Tokenized Securities Markets
Crypto Lending, Custody, Public Offerings, Regulatory Sandbox, RFI Responses, Safe Harbor, Security Status, Tokenization, Trading
  • Tokenized securities traded via DeFi or CeDeFi platforms must comply with U.S. securities laws, including the Exchange Act, regardless of claims of decentralization or minimal intermediary involvement.
  • A clear and nuanced taxonomy is essential to distinguish between natively issued digital securities, wrapped tokens, SBS, and non-security instruments, ensuring proper application of securities laws and investor protections.
  • Fragmentation between tokenized and traditional securities markets poses risks to market integrity, and regulators must ensure fungibility, consistent trade reporting, and integration with existing infrastructures like Reg NMS, CAT, and SIPC.

  • The framework enforces strict adherence to the Illinois Biometric Information Privacy Act (BIPA) and California Consumer Privacy Act (CCPA/CPRA) by implementing local-only biometric processing, purpose limitation, and secure destruction protocols for biometric data.
  • It aligns institutional authentication procedures with the Uniform Commercial Code Article 4A by incorporating phishing-resistant authentication, dual control, and hardware-backed cryptographic protocols, establishing a benchmark for commercially reasonable security procedures.
  • The framework embeds appealable, time-bounded attestations and dispute resolution pathways, ensuring representatives can challenge erroneous integrity flags and maintain employment rights, consistent with regulatory expectations for procedural fairness.

Re: Request for Comment on Innovative Methods to Detect Illicit Activity Involving Digital Assets (Docket No. TREAS-DO-2025-0009)
Custody, RFI Responses, Safe Harbor, Security Status, Tokenization
  • The "Chains of Trust" model enables cryptographic self-certification of digital identities and data, which can enhance customer due diligence and reduce synthetic identity fraud in digital asset markets.
  • Institutions can use VDCs to attest to a customer’s compliance status without transmitting sensitive personal data repeatedly, supporting privacy and interoperability across financial institutions.
  • Linking legal entity identifiers to VDCs provides cryptographic proofs of beneficial ownership, while immutable provenance records offer regulators and law enforcement reliable audit trails for supervisory and enforcement purposes.

  • The SEC has jurisdiction over leveraged crypto ETFs and related securities products, and has previously blocked filings for extreme 5x leveraged ETFs to protect investors.
  • Leveraged crypto instruments offered to U.S. persons via unregistered platforms may fall under SEC oversight, especially when tied to assets potentially classified as securities.
  • Joint SEC-CFTC efforts in 2025 have initiated regulation of onshore perpetual contracts with leverage limits, but offshore platforms remain largely unregulated, posing risks to U.S. retail investors.
