OKX Unveils Rubix for Institutional Digital Assets
OKX, a leading global digital asset exchange and on-chain technology company, has launched OKX Rubix, a modular workflow solution designed for regulated financial institutions. The platform enables banks and financial entities to offer digital-asset services to their clients without building new infrastructure or adding operational complexity.
Rubix fits naturally into institutions’ existing front-, middle-, and back-office processes. It brings together essential components such as market access, execution, custody, settlement, and controls into a unified framework. By integrating these critical functions, Rubix allows institutions to maintain their own client experience, policies, and governance—while OKX delivers the regulated infrastructure that powers them.
Building blocks for tailored workflows
Rubix empowers institutions to select only the components they need, aligning each with their existing operating models and risk frameworks. Its modularity supports regulated market access across multiple jurisdictions, including MiCA/MiFID II in Europe, VARA in the UAE, AFSL/AUSTRAC in Australia, CNV in Argentina, and U.S. MSB/MTL frameworks.
The platform also provides deep liquidity and execution through central-limit-order-book markets and OTC RFQ systems, ensuring best execution practices. Furthermore, post-trade settlement options enable delayed settlement for more capital-efficient operations. At the same time, connectivity features offer bespoke integrations with existing OMS/EMS systems and APIs, including FIX, REST, and WebSocket.
In addition, Rubix supports off-exchange custody, allowing institutions to select trusted, licensed bank custodians or third-party providers to minimize counterparty risk. Its collateral optimization framework gives users the flexibility to leverage fiat, stablecoins, crypto assets, or tokenized money-market funds.
Delivering simplicity through interoperability
Rubix was built to eliminate the operational and regulatory barriers preventing institutions from entering the digital-asset market. “Institutions are ready to meet client demand for digital assets but have been held back by complexity and compliance,” said Simon Ren, Senior Vice President, OKX Institutional. “Rubix removes those barriers with a modular, interoperable solution that integrates into established front, middle, and back-office processes. Rubix is deployed as a bespoke institutional workflow—designed and governed by the client—while OKX provides the regulated, scalable market infrastructure behind it.”
Moreover, Rubix is delivered in collaboration with a global network of regulated custodians and OMS/EMS providers, ensuring compliance and adaptability to regional regulatory requirements. This approach reinforces OKX’s vision that digital-asset adoption depends on interoperability, not fragmentation.
Currently, Rubix is live and operational with institutional partners across Europe, APAC, the UAE, and LATAM, with additional clients onboarding soon. Through Rubix, OKX reaffirms its commitment to simplifying institutional access to the digital-asset economy—one modular building block at a time.
