Kimber Digital Securities (KDS), a subsidiary of Plume Network (corporate name Kimber Labs Inc.), said on Tuesday it received membership approval from the U.S. Financial Industry Regulatory Authority (FINRA) and registered with the U.S. Securities and Exchange Commission (SEC) as a broker-dealer.

Plume, which developed the Plume blockchain, an Ethereum layer 2 blockchain, and the Nest vault protocol, described the registration as a major step toward achieving its goal of bringing the real world on-chain while complying with regulations.

KDS said it helps investors easily access tokenised real securities from their wallets. It said it supports protections for regulated firms, including best execution, independent oversight of operational and cyber risks, and clear and continuous disclosures.

KDS said it plans to help customers access SEC-regulated yield-bearing products through a stablecoin app once rules on payment stablecoins under the GENIUS Act take effect over the coming months. These include tokenised shares of funds run by major U.S. asset managers.

KDS said it plans to help customers access a broader U.S. on-chain capital market. Chris Yin (크리스 인), Plume's co-founder and CEO, said, "Stablecoins are bringing a new generation on-chain. What keeps them on-chain is yield and access to real investment opportunities that are fully covered by regulatory protections." He added, "Plume's broker-dealer keeps these users on-chain while connecting U.S. investors with an emerging on-chain capital market based on the infrastructure Plume has built over years."
