Kimber Digital Securities LLC, the broker-dealer affiliate of Kimber Labs, which operates as Plume, has completed registration with the U.S. Securities and Exchange Commission and received approval for membership in the Financial Industry Regulatory Authority. The approvals allow KDS to buy and sell securities for customers and, once it launches, provide eligible investors access to the Depository Trust Company, the central securities depository for U.S. markets. The company says investors will be able to hold digital claims on eligible stocks, exchange-traded funds and bonds in self-custody wallets while retaining book-entry claims recorded at DTC, which it says safeguards more than $100 trillion in assets. KDS says those DTC entitlements would carry the same rights associated with conventional assets, including dividends, voting entitlements and a direct claim on the underlying security, rather than relying on synthetic wrapped tokens. The platform is designed to connect traditional securities infrastructure with a public EVM-compatible blockchain and support stablecoin applications offering SEC-regulated, yield-bearing products, including tokenized interests in funds managed by leading U.S. asset managers, as rules under the GENIUS Act come online. The firm is also designed to provide protections associated with regulated brokerage, including best execution, independent oversight of operational and cyber risk, and continuing disclosure. The development follows Plume affiliates Kimber Transfer Agency, which registered with the SEC in September 2025, and Kimber Digital Assets Bermuda, which became a regulated vault curator in May. Plume said its vault protocols held $250 million in total value locked and processed approximately $1 billion in volume as of September 30, 2026.
