On May 17, 2023, Prometheum Ember Capital LLC (Prometheum Ember Capital), a subsidiary of Prometheum Inc., received approval from the Financial Industry Regulatory Authority (FINRA) to operate as a special purpose broker-dealer (SPBD) for digital assets. Prometheum Ember Capital is the first SPBD allowed to operate as a broker-dealer and as a qualified custodian in the United States. This approval follows guidance issued by the U.S. Securities and Exchange Commission (the Commission) permitting an SPBD to custody digital assets so long as it complies with the Securities and Exchange Act (SEA) rule 15c3-3 (the Customer Protection Rule). This SPBD addresses the lack of investor protection in the digital assets space by offering both retail and institutional investors an opportunity to custody their digital assets with an SEC-registered SPBD and a FINRA-member firm.
