Institutional-Grade Digital Securities Infrastructure
Non-custodial brokering, atomic settlement, and SEC-compliant ATS infrastructure — purpose-built for broker-dealers and institutional platforms entering digital securities.
Trusted by leading institutions
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.
SEC-Registered
Fully registered broker-dealer with FINRA membership and SIPC protection
Non-Custodial
Self-custody architecture — assets never leave customer wallets
Atomic Settlement
Trade and settlement in a single block with L1 finality
From Traditional Security to Digital Token
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.
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.
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
Three Integrated Pillars
A unified infrastructure stack delivering brokering, dealing, and exchange services for the institutional digital securities market.
Each pillar operates independently but integrates seamlessly — enabling broker-dealers and institutional platforms to adopt one, two, or all three services through a single API.

Atomic Onchain Settlement
Trades settle in a single block on Plume's Ethereum L2, with hard finality secured by Ethereum's Proof-of-Stake consensus.
Plume L2 is an Arbitrum Orbit rollup submitting compressed transaction batches to Ethereum L1. Hard finality inherits Ethereum's Proof-of-Stake security, providing irreversible settlement guarantees for all digital securities transactions.
Compliance-First Architecture
Compliance is foundational, not supplementary. Every layer of the Plume stack is designed around SEC, FINRA, and BSA requirements from day one.
SEC & FINRA Registration
Kimber operates as a fully registered broker-dealer (SEC) and member of FINRA and SIPC. All brokering, dealing, and ATS operations are conducted within the perimeter of federal securities regulation.
ATS Regulatory Framework
The Plume ATS (Rooster) operates under Regulation ATS with Form ATS and Form ATS-R filings. Fair access standards, display obligations, and confidentiality of subscriber information are enforced at the protocol level.
BSA / AML / Sanctions
Integrated BSA compliance with automated KYC/AML procedures and real-time sanctions screening via TRM Labs onchain oracles. Customer identification program (CIP), suspicious activity reporting (SAR), and currency transaction reporting (CTR) are fully implemented.

How We Protect Your Assets
Non-Custodial Architecture
Customer assets remain in self-custody wallets at all times. Kimber never takes possession, custody, or control of customer funds or securities.
Qualified Third-Party Custody
Underlying assets backing tokenized securities are held by qualified custodians under SEC Rule 15c3-3(k)(2)(i), with independent verification and daily reconciliation.
SIPC Membership
As a SIPC member, eligible customer accounts benefit from Securities Investor Protection Corporation coverage, providing an additional layer of protection.
Onchain Transparency
All transactions, compliance checks, and settlement events are recorded on an immutable blockchain ledger — providing auditable, time-sequenced records that satisfy SEC audit requirements.
Diversified Fee Architecture
Five distinct revenue streams across brokering, dealing, and exchange operations.
B2B Customer Model
Kimber serves as infrastructure — never facing retail directly.
