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.
