OKX Unveils Rubix, a Modular Digital Assets-as-a-Service Platform for Financial Institutions

OKX, a leading global digital asset exchange and on-chain technology company, has launched OKX Rubix, a modular Digital Assets-as-a-Service (DAaaS) solution designed to enable regulated financial institutions to integrate and offer digital-asset products to clients without building new infrastructure or adding operational complexity. The platform serves as a flexible institutional layer that seamlessly integrates into existing front-, middle-, and back-office systems, unifying key operational components such as market access, execution, custody, settlement, and risk controls into a single interoperable framework.

Simon Ren, Senior Vice President of OKX Institutional, emphasized that "institutions are ready to meet client demand for digital assets but have been held back by complexity and compliance." He added that "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.

The modular design allows institutions to select only the components they need, tailoring them to existing risk frameworks, governance models, and client workflows. Key features include regulated market access under frameworks like MiCA/MiFID II in Europe, VARA in the UAE, AFSL/AUSTRAC in Australia, CNV in Argentina, and U.S. MSB/MTL licenses; access to OKX’s central limit order book and OTC RFQ systems for liquidity and execution; a capital-efficient delayed settlement model that eliminates exchange pre-funding; connectivity via FIX, REST, and WebSocket APIs; off-exchange custody integration with licensed bank custodians; and support for collateral optimization using fiat, stablecoins, crypto assets, and tokenized money-market funds. Additional services encompass credit lines, loans, fiat on/off ramps, and advanced account governance controls.

Rubix is already live and operational with institutional partners across Europe, APAC, the UAE, and LATAM, with more institutions currently onboarding. This reflects growing demand for enterprise-grade digital asset infrastructure that prioritizes security, compliance, and interoperability, underscoring OKX’s philosophy that adoption will be driven by interoperability rather than fragmentation.
