Plume’s Broker-Dealer Unit Opens Path to Onchain U.S. Securities

Kimber Digital Securities (KDS), an affiliate of Kimber Labs that operates the Plume brand, has secured FINRA membership and SEC registration as a broker-dealer. The status lets it buy and sell securities for clients and access the Depository Trust Company (DTC). The thesis: tokenized U.S. equities are being built on the existing legal plumbing, not around it.

A Broker-Dealer Designed to Link the Chain to the U.S. System

On November 10, 2026, in New York, Kimber Digital Securities LLC (KDS) announced approval of its membership in the Financial Industry Regulatory Authority (FINRA) and its registration with the Securities and Exchange Commission (SEC) as a broker-dealer. According to the release, KDS can now buy and sell securities on behalf of its clients. The registration also gives it access to the DTC, the depository for U.S. securities markets, which Plume says holds more than $100 trillion in assets.

The setup relies on existing U.S. market structure. An investor does not directly hold legal title to a security. Instead, the investor holds a “security entitlement” with its broker-dealer, representing a proportional share of the pool of securities the broker-dealer holds for its clients. The broker-dealer holds a matching entitlement at the DTC, which records the position in its book-entry system. The DTC holds the securities through its nominee, Cede & Co., which appears as registered holder on the issuer’s register and on the cap table kept by the transfer agent.

What the registration changes

• Buying and selling securities for clients under FINRA supervision.
• Transfers between off-chain and onchain formats through the DTCC’s ACATS system.
• A stated best-execution principle, independent oversight of operational and cyber risks, and continuous disclosure.

Tokens at the First Level of the Chain, Under DTC Control

The technical core is the nature of the token. According to Plume, it is not a simple wrapper, meaning a representation of an asset held off-chain. The tokens are meant to record a position inside this existing structure and to keep the rights attached to traditional securities: dividends, voting rights and a direct claim on the underlying equity, ETF or eligible bond.

“The token records a position inside this existing chain. It is not a wrapper around an asset held outside the chain.”

Self-custody comes with a trade-off. Salman Banaei, Plume’s chief executive, says KDS never takes possession of customer assets. However, the DTC keeps a “root wallet” with authority to convert, transfer, mint or burn any token, including without the holder’s private key. The mechanism is designed to reverse erroneous transfers and replace lost or stolen tokens. Plume links this to the SEC no-action framework of December 2025, under which the token is not a bearer instrument outside DTC control.

A second major caveat: only blockchains that meet DTC eligibility criteria and are approved by the DTC can carry these tokens. The sources do not say whether the Plume blockchain has received that approval. For investors, this is the most important open question in the announcement.

A Stablecoin-First Distribution Strategy

The first target is stablecoin applications and holders of tokens backed by an external reference, notably the U.S. dollar. As the GENIUS Act’s rules for payment stablecoins take effect, KDS wants these applications to offer clients access to SEC-regulated yield-bearing products, including tokenized shares in funds run by major U.S. asset managers.

“Stablecoins are bringing a new generation onchain. What keeps them there is yield and access to real investment opportunities with full regulatory protections.”

Banaei says KDS is a new platform and that no Kimber-developed platform previously offered access to U.S. users. The first offerings, which may still change, are expected to include regulated asset management products issued by registered investment companies and DTCC securities entitlements. The compliant U.S. products already issued on the Plume chain are WisdomTree’s tokenized funds, governed by the Investment Company Act of 1940.

The business model rests mainly on commissions and transaction fees. KDS also plans integration and platform fees charged to distribution partners, including payment apps, crypto wallet providers and other broker-dealers. The release cites a universe of more than 700 million crypto wallet holders, more than 700 applications connected through WalletConnect, and a projection of more than 5 billion digital wallet users in 2026. These figures describe a potential market, not volumes captured by KDS.

Traction: Figures That Do Not Line Up

Plume’s metrics come from three documents with different dates and scopes. Holders, wallets, distributed value, TVL and volume are not defined in the same way, which rules out a clean time series.

The September memo cites roughly 60,000 holders since June 2025 and about $30 million more in Nest on other blockchains. In March, Plume attributed to its network close to half of the world’s real-world asset wallets excluding stablecoins, based on the data cited. These amounts remain at the scale of a nascent market, and the move from testimony to release does not follow a common methodology.

Competition and Regulatory Build-Out

Banaei contrasts Plume with BlackRock, Franklin Templeton, Securitize and Ondo, describing the gap as “primarily one of emphasis, not kind”. In his view, these players have concentrated tokenization of U.S. assets on institutional channels, permissioned or offshore, while KDS targets U.S. users and compliant distribution on U.S. soil.

The regulatory build-out is incremental. Kimber Transfer Agency registered with the SEC as a transfer agent in September 2025. In May 2026, the Bermuda subsidiary Kimber Digital Assets became a vault curator regulated by the Bermuda Monetary Authority. In August 2026, Plume joined the DTCC’s Digital Assets Solutions Industry Working Group. The September 22 memo still described KDS as pending registration and referred to a planned ATS based on a non-custodial automated market protocol. The November release confirms the broker-dealer status but does not mention ATS approval.

Plume’s investors include Apollo Global Management, Brevan Howard, F-Prime Capital (affiliated with Fidelity Investments), Galaxy Digital, Haun Ventures, Laser Digital (affiliated with Nomura) and SV Angel. The chain, live on mainnet since June 2025, is an Ethereum Layer 2 with sanctions and anti-money-laundering screening built into the protocol.

Outlook and Scenarios

KDS’s registration is a regulatory milestone, not a commercial launch. Plume presents it as a step toward U.S. capital markets that are truly onchain, yet no KDS product is available to U.S. clients yet. The sources provide no price data, trading volumes or quantified analyst reactions, so this assessment rests on the legal architecture and the reported metrics.

• Base case: gradual ramp-up through stablecoin applications, conditioned on GENIUS Act rules and DTC approval of the chain.
• Bull case: more asset managers and distribution partners, with verifiable growth in TVL and holders.
• Bear case: delayed chain approval, limits tied to DTC correction powers, or weak uptake of regulated products.
