Kimber Digital Securities, Plume’s affiliated broker-dealer, has been approved for Financial Industry Regulatory Authority (FINRA) membership and is now registered as a broker-dealer with the Securities and Exchange Commission (SEC). Kimber Digital Securities is a subsidiary of Kimber Labs Inc. (“Plume”), the developer of the Plume blockchain.

We’re announcing that Kimber Digital Securities, Plume’s affiliated broker-dealer, has been approved for Financial Industry Regulatory Authority (FINRA) membership and is now registered as a broker-dealer with the Securities and Exchange Commission (SEC). Kimber Digital Securities is a subsidiary of Kimber Labs Inc. (“Plume”), the developer of the Plume blockchain, the first Ethereum compliance and RWA-focused blockchain, and Plume Vaults, both of which embed sanctions and AML transaction screening at the protocol level.

This is a milestone for Plume and a major step toward achieving Plume’s mission to bring the real world onchain, compliantly.

The broker-dealer is built to put real tokenized securities with full shareholder rights into an investor’s wallet. It carries the protections of a regulated firm, e.g., best execution, independent oversight of operational and cyber risk, and clear, continuous disclosure.

Regulatory alignment has been central to Plume from day one. Kimber Transfer Agency registered as a transfer agent with the SEC in September 2025. The transfer agent lets issuers manage digital securities, handle on- and offchain shareholder records, share issuance, transfers, and dividends.

In May, Plume’s Kimber Digital Assets Bermuda subsidiary became a regulated vault curator with authorization to issue tokenized investments from the Bermuda Monetary Authority. Plume Vaults protocol now accounts for $250 million in Total Value Locked, with approximately $1 billion in volume flowing through the platform, a sign of how quickly demand is growing for accessible, onchain products backed by institutional assets.*

Onchain by design

Plume was built to bring real-world assets onchain, with compliance embedded at the protocol level rather than bolted on after the fact. A regulated broker-dealer affiliate completes the picture: securities that can be held, transferred, and settled onchain, continuously and composably, while the rights and protections of traditional ownership travel with them.

That’s Plume in practice: real assets, real ownership, and real onchain utility. The Open Finance infrastructure for the next evolution of capital markets.

Access to yield for payment stablecoin users

As regulations relating to payment stablecoins under the GENIUS Act come online in coming months, Kimber Digital Securities will enable provide stablecoin applications to offer customers access to SEC-regulated yield-bearing products, including tokenized shares in funds managed by leading U.S. asset managers, as well as access to broader American onchain capital markets.

Chris Yin, CEO and Co-Founder of Plume: “Stablecoins are bringing a new generation onchain. What keeps them there is yield and access to real investment opportunities with full regulatory protections. Our broker-dealer is how we keep those users onchain and how we connect American investors to the emerging onchain capital markets we’ve spent years building the infrastructure to support.”

Digital wallets are where this audience already lives: over 700 million people hold a crypto wallet today, more than 700 wallet apps connect through WalletConnect alone, and digital wallet users overall are projected to surpass 5 billion by 2026. Each is a potential partner for the Firm to bring its users access to U.S. tokenized securities.

Through DTC, these users could reach the full universe of U.S. securities the Depository custodies, now over $100 trillion in assets, including a growing set of mutual funds issued in tokenized, unwrapped form, where the token is the real fund share recorded onchain rather than a wrapper.

Access to DTC tokenized entitlements

The broker-dealer unlocks a more direct form of securities ownership for the American customer that traditional markets have never made possible, powered by DTC’s tokenized securities model and the rise of issuer-sponsored tokenized equities.

Plume has been a member of the DTCC’s Digital Assets Solutions Industry Working Group since August and through the Firm will help bring access to DTC tokenized securities to its customers. In the U.S. market, securities ownership runs through a chain of custody with several tiers, and broker-dealer registration lets the Firm connect tokenized securities into that chain. At the base of the chain, an investor does not hold legal title to the security. The investor holds a security entitlement against the broker-dealer, which acts as the securities intermediary. A security entitlement is a pro rata property interest in the pool of that security the broker-dealer holds for its customers. The broker-dealer is a participant in the Depository Trust Company (DTC), and it holds a matching security entitlement against DTC. DTC records that position in the book-entry records of the central securities depository. DTC holds the securities through its nominee, Cede & Co. Cede & Co. is the registered holder of record on the issuer’s securities register, the capitalization table kept by the transfer agent.

Tokenized securities offered through the broker-dealer are intended to represent that base tier security entitlement onchain. It is the same legal interest investors hold today. The position is supported by the broker-dealer’s entitlements at DTC and settled on established DTCC infrastructure. The token records a position inside this existing chain. It is not a wrapper around an asset held outside the chain. Because of that, the token is intended to carry a settled, recognized claim on the underlying U.S. equity, ETF, or bond. Investors can also use ACATS to move entire portfolios between offchain and onchain formats, in either direction.

DTC entitlements give these tokens what most onchain assets lack: a settled, recognized claim on the real U.S. equity, ETF, or bond asset.

“Registration is a threshold, not a finish line. It lets us do something tokenization has long promised but rarely delivered at scale: move real, unwrapped securities onto open, programmable infrastructure without giving up the protections investors count on,” said Salman Banaei, General Counsel at Plume. “We believe that broadens access, tightens market efficiency, and connects global capital to U.S. markets and that onchain rails can improve capital formation with outcomes as good or better for markets, investors, issuers, and policymakers alike. This is our first step toward building genuinely onchain American capital markets.”

Built as one

Finance is converging. One system can carry the trust of regulated securities and the reach of open networks, and that is what the Firm and Plume are building together.

Real ownership. Onchain distribution. Designed for compliance.

For Kimber Digital Securities and Plume, this is the next step in bringing the real world onchain.

As I testified before the House Financial Services Committee in March, the SEC needs to update its approach to broker-dealers so they can fully support capital markets as they move onchain.
