The U.S. SEC's Division of Trading and Markets has issued a staff statement allowing specific user interfaces for crypto asset securities trading, such as websites, wallet plugins, and mobile front-ends, to operate without broker-dealer registration under certain conditions. These conditions include not providing investment advice, not routing orders on behalf of users, and not holding user assets. The interfaces can charge fixed fees or transaction-based fees. This guidance applies to self-custody wallet trading front-ends and is set to expire in five years unless the SEC takes further formal action.
