End-to-End Digital Securities Infrastructure

Built for Institutions

Kimber provides a full-stack digital securities infrastructure designed from the ground up for regulated financial institutions. Every component — from order routing to settlement — meets the operational and compliance standards required by broker-dealers, asset managers, and institutional platforms.

Non-Custodial by Design

Customer assets never touch Kimber servers. All trades execute directly between self-custody wallets through smart contracts, eliminating counterparty risk and simplifying the custody model under SEC Rule 15c3-3.

Onchain Compliance

Compliance is not an afterthought — it is embedded at the protocol level. Smart contract hooks enforce KYC, AML, sanctions screening, accreditation verification, and transfer restrictions at every transaction, automatically and immutably.

How It Works

From Traditional Security to Digital Token

1

Asset Origination

The issuer identifies a traditional security — such as a 40 Act fund, corporate bond, or asset-backed security — and engages Kimber to manage the tokenization process. Legal structuring, custody arrangements, and compliance documentation are established.

2

Token Creation & Custody

Kimber mints 1:1 redeemable digital tokens on the Plume L2 network, backed by the underlying custodied assets. Smart contracts enforce transfer restrictions, holder eligibility, and automated yield distribution to wallet holders.

3

Distribution & Trading

Tokenized securities are distributed to qualified investors and made available for secondary trading on the Plume ATS (Rooster). All transactions clear and settle atomically with full compliance hook enforcement.

Kimber manages the full tokenization lifecycle — from legal structuring and custody to secondary market trading on a compliant ATS. Learn more about dealing
