SEC Opens Public Comment on Crypto and On-Chain ETF Rules

The SEC is asking market participants how it should regulate ETFs that hold crypto assets or settle on blockchain networks. Chairman Paul Atkins issued a statement outlining the scope of the inquiry, which explicitly covers crypto-linked and on-chain product designs.

For ETF issuers, the comment period is a chance to shape rules before they are written. For investors, clarity could accelerate the launch of products that currently sit in regulatory limbo. The request covers structures that go beyond traditional equity and fixed-income wrappers, according to the SEC statement.

What the SEC Is Asking

The SEC's request centers on the regulatory treatment of ETF structures that do not fit neatly into existing fund categories. These include products that hold digital assets directly, use on-chain settlement mechanisms, or provide exposure to crypto markets through novel wrapper designs. The agency is casting a wide net across the full spectrum of novel ETF innovation, rather than focusing on a single asset class.

Crypto ETFs raise questions about custody and valuation that existing rules were not designed to address. On-chain products add another layer: settlement outside traditional financial infrastructure. The SEC has historically cited concerns about market manipulation as a reason to delay or reject crypto ETF applications. The public input process may seek to establish what surveillance-sharing agreements and market integrity standards should apply to novel products.

The Custody and Pricing Hurdles

How digital assets are held, secured, and verified remains one of the most contested issues in crypto ETF regulation. Traditional ETF custody arrangements rely on qualified custodians under existing securities rules. Crypto custody introduces unique risks around private key management and blockchain-specific vulnerabilities.

ETFs require reliable, real-time pricing for creation and redemption. Crypto markets operate across fragmented global venues with varying liquidity, creating challenges for establishing a consistent net asset value. On-chain products that reference decentralized exchange pricing face additional scrutiny.

Novel ETF structures may require new disclosure frameworks. Products that interact with smart contracts, on-chain protocols, or decentralized governance systems introduce risks that existing prospectus templates do not adequately cover.

The SEC's inclusion of these products in the public input request does not signal approval or rejection of any specific proposal. It reflects recognition that the pipeline of novel ETF filings now includes a significant number of crypto and on-chain designs, and that the agency needs a coherent framework to evaluate them.

Timeline and Next Steps

The public comment period will run for a defined window, after which SEC staff will review submissions and determine next steps. Possible outcomes include formal rulemaking proposals, updated staff guidance, or additional roundtable discussions. Issuers should not expect near-term approvals as a direct result of this input period.

For ETF issuers, the process creates an opportunity to influence the rules before they are written. Firms that submit detailed comments on custody standards, disclosure requirements, and market structure considerations could shape how the SEC draws the boundaries for permissible product designs.

The SEC has also been reviewing adjacent product categories. The Block reported that the agency is examining prediction market ETFs, another novel product type that stretches existing regulatory definitions.

Comment requests of this nature do not trigger immediate rule changes. The process typically unfolds over months, with the SEC reviewing submissions, potentially holding roundtables, and then deciding whether to propose formal rulemaking.

Atkins said the agency is seeking input to ensure its rules keep pace with innovation. The SEC's crypto task force page will host submission details and deadlines.
