By Plume has added a U.S. broker-dealer to its tokenization infrastructure after affiliate Kimber Digital Securities secured registration with the Securities and Exchange Commission and membership in the Financial Industry Regulatory Authority, creating a regulated route for the company to distribute tokenized securities to U.S. investors.
The approval announced November 10 allows Kimber Digital Securities, or KDS, to conduct broker-dealer activities and is intended to connect investors using self-custodial wallets with securities entitlements tied to assets held through the Depository Trust Company. Plume expects the new platform to launch in the first half of 2027.
The distinction from many existing tokenized-stock products is important. KDS plans to represent an investor’s existing securities entitlement within the U.S. intermediated ownership system rather than issue a separate synthetic token providing only economic exposure to a stock or fund.
What Will KDS Investors Actually Own?
U.S. securities held through brokers generally sit within a layered ownership structure. DTC holds securities through its nominee, while broker-dealers maintain entitlements at DTC and customers hold corresponding security entitlements through their brokers.
KDS plans to represent that customer-level entitlement onchain. The token would therefore record a position within the existing securities infrastructure rather than function as a detached wrapper around an asset held elsewhere.
Eligible positions could include stocks, ETFs and bonds and are intended to retain the economic and investor rights associated with the conventional security entitlement, including dividends and voting rights where applicable.
The structure builds on DTC’s own tokenization program, which received SEC staff no-action relief in December 2025. DTC subsequently launched its Tokenization Service in 2026, initially covering selected equities, ETFs and U.S. government securities. Morgan Stanley has already used DTCC infrastructure to tokenize U.S. equities and Treasuries, showing that the model is moving into production among traditional financial institutions.
Investor Takeaway
KDS is not simply creating blockchain price exposure to conventional securities. Its commercial proposition depends on connecting blockchain wallets to the same entitlement structure already used by U.S. brokerage accounts, potentially narrowing the legal gap between tokenized and conventionally held investments.
Does Self-Custody Remove Traditional Market Controls?
No. Customers are expected to control their own wallet keys, but the tokenized entitlements will still operate within DTC’s regulated infrastructure rather than as unrestricted bearer assets.
Under the DTC framework, supported networks and wallets must meet eligibility requirements, and DTC retains administrative powers over tokenized positions. Those controls can include minting, burning and transferring tokens when required to correct errors or replace compromised holdings.
That makes the model materially different from permissionless crypto assets, where control of a private key can be equivalent to final control of the asset. Blockchain records provide the delivery mechanism, while the legal entitlement remains anchored to existing securities infrastructure.
Plume joined the DTCC Digital Assets Solutions Industry Working Group in August, but KDS has not said that the Plume blockchain itself has been approved as a DTC-supported network. That will be an important operational detail before launch.
Why Is Plume Building Several Regulated Entities?
The broker-dealer fills another part of a regulatory stack Plume has assembled around real-world assets. Kimber Transfer Agency registered with the SEC as a transfer agent in September 2025, allowing it to maintain shareholder records and process issuance, transfers and distributions.
In May, another affiliate, Kimber Digital Assets Bermuda, received authorization from the Bermuda Monetary Authority to operate tokenized investment vaults. The Bermuda license gave Plume a regulated structure for its onchain vault business, while the new U.S. broker-dealer addresses domestic securities distribution.
The company says its Plume Vaults infrastructure had about $250 million in total value locked and approximately $1 billion in cumulative volume as of September 30.
Investor Takeaway
Plume is assembling separate regulatory functions for issuance records, brokerage and tokenized investment products rather than relying on one offshore structure. The next test is whether those licenses translate into meaningful transaction and distribution volumes.
Where Could KDS Make Money?
KDS expects transaction revenue from commissions and other trading fees, alongside integration and platform charges from wallets, payment applications and broker-dealers that connect customers to its infrastructure.
Stablecoin applications are one targeted distribution channel. Plume argues that users holding dollar-backed tokens increasingly need regulated yield-bearing products if they are to keep capital within blockchain-based financial systems. KDS plans to offer access to products including tokenized shares of registered investment funds.
Competition is already increasing. BlackRock-backed Securitize has expanded from tokenized funds into public equities and financing infrastructure, while WisdomTree and Ondo have developed different models for bringing traditional investments onchain. Securitize’s planned River One acquisition shows how tokenization providers are extending beyond issuance into financing and other financial services.
KDS is not live yet, and its initial product list, supported blockchains, pricing and distribution partners remain to be finalized. The broker-dealer registration therefore removes an important regulatory barrier, but commercial adoption will depend on what actually becomes available when the platform launches in 2027.
Investor Takeaway
The important milestone is not simply putting stocks on a blockchain. KDS is testing whether regulated U.S. securities entitlements can become usable assets inside wallets and stablecoin applications without severing their connection to established market infrastructure.
