Plume Affiliate Kimber Digital Securities Wins SEC Registration and FINRA Membership

Kimber Digital Securities LLC, a broker-dealer subsidiary of Plume developer Kimber Labs Inc., has gained membership in the Financial Industry Regulatory Authority (FINRA) and registered as a broker-dealer with the Securities and Exchange Commission (SEC) on Nov. 10, 2026 ¹. The milestone permits the firm to legally intermediate tokenized US securities, connecting onchain digital wallets with traditional market clearing rails ¹.

Under the registered broker-dealer framework, the firm intends to offer retail and institutional investors access to unwrapped securities entitlements backed by the Depository Trust Company (DTC) ¹. Instead of relying on offchain synthetic wrappers, the onchain tokens will represent base-tier security entitlements against the broker-dealer, which holds corresponding positions through DTC book-entry records under nominee Cede & Co. ¹. The architecture is designed to support conventional shareholder protections, including dividends and voting rights, alongside automated customer account transfers via the Automated Customer Account Transfer Service (ACATS) between onchain wallets and traditional accounts ¹.

Expanding Regulated Real-World Asset Rails

The regulatory approval expands Kimber Labs' existing compliance stack across multiple jurisdictions ¹. Kimber Transfer Agency secured SEC registration as a transfer agent in September 2025 to manage on- and offchain cap tables, while Bermuda subsidiary Kimber Digital Assets Bermuda received authorization as a vault curator from the Bermuda Monetary Authority in May 2026 ¹. As of Sept. 30, 2026, the Plume Vaults protocol accounted for $250 million in total value locked and approximately $1 billion in cumulative volume ¹. The institutional push mirrors broader industry efforts to bridge Wall Street infrastructure with onchain ledgers, comparable to initiatives like Blockchain.com and the NYSE's tokenized trading partnership.

Looking ahead, Kimber Digital Securities plans to interface with payment stablecoin applications anticipating implementation of the GENIUS Act, distributing SEC-regulated yield-bearing instruments and mutual fund shares directly to self-custodial wallets ¹. The firm has also participated in the Depository Trust & Clearing Corporation's (DTCC) Digital Assets Solutions Industry Working Group since August 2026 ¹. At the time of writing, broader markets traded lower, with $BTC slipping 2.5% to $73,219 and $ETH dropping 5.1% to $2,029 amid a market sentiment score of 32.
