Hester Peirce is fueling a regulatory clash inside the SEC after new guidance on crypto interfaces raised fresh questions about whether wallets and front-end tools should be treated as broker-dealers.

The pro-crypto SEC commissioner urges public comments to help refine regulations, aiming to preserve innovation in user tools for self-custody and blockchain interactions without overly broad securities law interpretations.

Hester Peirce Calls for Formal Rulemaking In SEC’s New Crypto Interface Guidance

The SEC Division of Trading and Markets has released interim guidance addressing how broker-dealer rules apply to crypto user interfaces.

The statement focuses on “covered user interfaces” used to prepare and transmit blockchain-based transactions.

Under the framework, certain wallet-connected interfaces would not be classified as broker-dealers if they meet strict conditions.

These include allowing users full control over transaction parameters, avoiding trade solicitation, and relying on objective routing and pricing mechanisms.

The SEC said the guidance is temporary and may be withdrawn within five years if not formalized through rulemaking. Officials described it as an interim step while broader crypto regulatory questions remain under review.

Commissioner Hester Peirce responded by welcoming the clarity but warning that staff guidance is not enough to resolve deeper legal uncertainty.

She argued that relying on temporary statements leaves developers exposed to shifting interpretations of the broker definition under securities law.

Peirce emphasized that wallets and interfaces should not automatically be treated as brokers simply for transmitting user instructions or displaying market data.

Peirce also called for full Commission rulemaking to modernize the broker definition in line with blockchain based market structures.

“Crypto is forcing the Commission to confront its inner demons that have driven it toward ever more expansive readings of the securities laws,” wrote Peirce in a statement.

She said fragmented enforcement and guidance have created long standing uncertainty for innovators.

Crypto Developers Face Regulatory Gray Area

The SEC framework attempts to distinguish between neutral software providers and firms that actively execute trades, route orders, or manage customer funds.

Entities that provide custody, investment advice, or transaction execution remain subject to broker dealer requirements.

Industry participants have repeatedly argued that unclear classification rules have slowed innovation in self custodial wallets and decentralized finance interfaces.

This new guidance is intended to provide temporary clarity but does not permanently resolve legal definitions.

The SEC is now soliciting public input on how broker definitions should apply to emerging blockchain technologies. The outcome could determine whether crypto interfaces are treated as neutral software tools or regulated financial intermediaries.

The next phase of rulemaking may prove decisive in shaping how digital asset markets evolve in the United States.
