Kimber Digital Securities, the broker-dealer affiliated with blockchain developer Plume, is now registered with the U.S. Securities and Exchange Commission (SEC) and has been approved for membership in the Financial Industry Regulatory Authority (FINRA). The company announced the approvals on Nov. 10 and said it plans to use them to give U.S. investors a regulated way to hold real stocks, ETFs and bonds as tokens in their own crypto wallets.
Registration as a broker-dealer places the firm under SEC oversight, with FINRA membership bringing additional self-regulatory obligations. FINRA, the self-regulatory organization that writes and enforces rules for U.S. brokerage firms, covers areas such as capital requirements, custody of customer assets and conduct standards. The approval was disclosed in an official announcement issued by the company.
Kimber Digital Securities is a subsidiary of Kimber Labs Inc., which does business as Plume. Plume develops the Plume blockchain, an Ethereum layer 2 network built for real-world assets, along with the Nest vault protocol.
The Same Claim, Recorded Onchain
The firm says its tokens are meant to represent the same legal interest investors already hold through a conventional brokerage account. In the United States, most investors do not hold legal title to their shares. Instead, they hold a "security entitlement" against their broker, and that broker holds a matching entitlement at the Depository Trust Company (DTC). DTC holds the securities through its nominee, Cede & Co., which is listed as the owner on the issuer's records.
According to the company, each token records a position inside this existing chain of custody rather than serving as a wrapper around an asset held somewhere else. The company emphasized that this differs from wrapped tokens, which represent a claim on an asset held by a separate custodian. On that basis, token holders are meant to keep rights such as dividends, voting and a direct claim on the underlying asset. Investors would also be able to use ACATS, the Automated Customer Account Transfer Service, to move whole portfolios between onchain and offchain formats.
DTC, part of the Depository Trust & Clearing Corporation (DTCC), holds more than $100 trillion in assets, according to the release. Plume has been part of the DTCC's Digital Assets Solutions Industry Working Group since August. A figure of that scale underscores how much existing custody and settlement infrastructure stands behind any effort to represent U.S. stocks and bonds onchain.

Stablecoin Users and Yield
The company is also aiming at people who already use stablecoins. Rules for payment stablecoins under the GENIUS Act, the U.S. federal stablecoin law, are set to take effect in the coming months. Kimber Digital Securities says it will let stablecoin apps offer customers SEC-regulated products that pay yield once those rules are in place. That makes the rollout of the GENIUS Act rules the practical gate for when such offerings can begin. The planned lineup includes tokenized shares of funds run by large 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," said Chris Yin, CEO and co-founder of Plume.
The firm also pointed to the scale of the wallet ecosystem, noting that more than 700 million people hold a crypto wallet today and that over 700 wallet apps connect through WalletConnect alone.
General Counsel Salman Banaei called the registration "a threshold, not a finish line." He said it lets the company move "real, unwrapped securities onto open, programmable infrastructure" while keeping investor protections.
Other Registrations and Open Items
The broker-dealer approval adds to a set of licenses already held by Plume's affiliates. Kimber Transfer Agency registered with the SEC as a transfer agent in September 2025. In May, the Kimber Digital Assets Bermuda unit was approved by the Bermuda Monetary Authority as a regulated vault curator authorized to issue tokenized investments.
The company said some services, including access to DTC tokenized entitlements and the stablecoin products, are still under development. It also noted that FINRA membership and SEC registration do not mean regulators endorse the firm or its products.
As of Sept. 30, 2026, the Plume Vaults protocol held $250 million in total value locked, and about $1 billion in volume has moved through the platform. Those figures relate to the Plume protocol itself and not to the newly registered broker-dealer.
