OKX Launches Rubix, a Modular Digital Assets-as-a-Service Platform

OKX, a leading global digital asset platform and on-chain technology company, has announced the launch of OKX Rubix, a modular Digital Assets-as-a-Service (DAaaS) answer that enables regulated financial institutions to integrate and offer digital-asset products to clients—without building new infrastructure or adding operational complexity.

Designed as a flexible institutional layer, Rubix seamlessly integrates into an institution’s existing front-, middle-, and back-office systems. It unifies key operational components—market access, execution, custody, settlement, and risk controls—into a single interoperable framework, allowing banks, asset managers, and brokers to deliver compliant digital-asset services while retaining their own client experience, branding, and governance standards.

“Institutions are ready to meet 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 answer 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.”

Takeaway

Building Blocks for Institutional-Grade Digital Asset Infrastructure

Rubix’s modular design allows institutions to select only the components they need, tailoring them to existing risk frameworks, governance models, and client workflows. Its architecture supports deep jurisdictions, offering full regulatory alignment and operational interoperability.

Key Components Include:

• Regulated Market Access: Full coverage under MiCA/MiFID II (Europe), VARA (UAE), AFSL/AUSTRAC (Australia), CNV (Argentina), and U.S. MSB/MTL licenses.
• Liquidity & Execution: Access to OKX’s central limit order book and OTC RFQ systems for best-in-class price discovery and execution.
• Post-Trade Settlement: Capital-efficient delayed settlement model that eliminates the need for platform pre-funding.
• Connectivity: Native integrations with institutional OMS/EMS platforms, supporting FIX, REST, and WebSocket APIs.
• Off-platform Custody: Integration with licensed bank custodians and third-party providers to minimize counterparty exposure.
• Collateral Optimisation: Support for fiat, stablecoins, crypto assets, and .
• Additional Services: Credit lines, loans, fiat on/off ramps, and advanced account governance controls.

By embedding these capabilities, Rubix allows financial institutions to offer compliant digital-asset services—trading, custody, and settlement—under their own branding while OKX delivers the regulated market infrastructure behind the scenes.

Takeaway

Global Coverage and Institutional Adoption

Rubix is already live and operational with institutional partners across Europe, APAC, the UAE, and LATAM. OKX confirmed that additional institutions are currently onboarding, demonstrating growing demand for enterprise-grade , compliance, and interoperability.

Delivered through partnerships with regulated custodians and OMS/EMS providers, Rubix supports customizable regional configurations that reflect local licensing obligations and service-level requirements. This model underscores OKX’s philosophy that digital-asset adoption will be driven by interoperability—not fragmentation.
