23 October 2025; Dubai, Frankfurt, São Paulo, Sydney — OKX, a leading digital asset exchange and global on-chain technology company, today announced OKX Rubix, a modular workflow solution that enables regulated financial institutions to provide digital-asset services to their clients and customers—without building new infrastructure or adding operational burden.
Rubix fits seamlessly into an institution’s existing front-, middle-, and back-office processes —assembling the core components of market access, execution, custody, settlement, and controls into one coherent framework. By solving the operational puzzle, Rubix lets institutions provide regulated digital-asset services to their clients and customers while retaining their own client experience, policies and governance.
Building Blocks for a Bespoke Institutional Workflow
Institutions can select only the components they need and align them to existing operating models, risk frameworks and governance structures:
-
Regulated Market Access — includes MiCA/MiFID II (Europe), VARA (UAE), AFSL/AUSTRAC (Australia), CNV (Argentina), and U.S. MSB/MTL coverage.
-
Liquidity & Execution — deep central-limit-order-book markets and OTC RFQ for best execution.
-
Post-Trade Settlement — delayed settlement for capital-efficient operations without exchange pre-funding.
-
Connectivity — bespoke integrations with existing OMS/EMS systems, plus FIX, REST and WebSocket APIs.
-
Off-Exchange Custody — select preferred licensed bank custodians and third-party providers to reduce counterparty risk.
-
Collateral Optimisation — flexibility to use fiat, stablecoins, crypto assets, and tokenized money-market funds.
-
Additional Services – include credit lines, loans, fiat on/off ramps, and enterprise-grade account controls.
Rubix allows financial institutions to offer regulated digital-asset services within existing channels, maintaining their own branding, policies, limits, data models and reporting, while OKX provides the regulated market infrastructure behind the scenes.
“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.”
Rubix is delivered in partnership with a global network of regulated custodians and OMS/EMS providers, enabling custom regional configurations that reflect local regulatory obligations, operating preferences and service-level requirements—reinforcing OKX’s belief that digital-asset adoption will be built on interoperability, not fragmentation.
Live today: Rubix is already operating with institutional partners across Europe, APAC, the UAE, and LATAM, with additional institutions currently onboarding.
— OKX Rubix. Puzzle solved.
