Streamlining institutional access to digital assets

Rubix allows banks, brokers, neobanks, and wealth managers to incorporate crypto trading, custody, settlement, and reporting without overhauling their current systems. Institutions can maintain their existing client interfaces, branding, and compliance frameworks while OKX provides the regulated market infrastructure in the background.

Through its modular architecture, Rubix fits directly into an institution’s front-, middle-, and back-office operations, connecting to order and execution management systems via FIX, REST, and WebSocket APIs. The solution also supports integrations with licensed custodians and third-party providers, enabling secure off-exchange storage and collateral optimization using fiat, stablecoins, or tokenized money-market funds.

Regulated and scalable for global markets

Rubix is structured to comply with major global regulatory standards, including MiCA/MiFID II in Europe, VARA in the UAE, AFSL/AUSTRAC in Australia, and U.S. MSB/MTL frameworks. The platform combines deep liquidity pools, OTC RFQ execution, and “trade first, settle later” post-trade settlement to enhance capital efficiency for institutional users.

By embedding crypto functionality directly into traditional financial systems, Rubix enables institutions to diversify their product offerings from retail crypto trading and stablecoin settlements to tokenized yield products without compromising governance or client control.

With the launch of Rubix, OKX aims to create a bridge between traditional finance and digital assets, positioning itself as a key enabler for regulated institutions entering the crypto economy.

In a recent development, OKX founder and CEO Star Xu revealed that the company quietly developed a decentralized perpetuals trading platform in 2023 through its Web3 division, targeting competitors like Hyperliquid and Aster as part of its broader DeFi strategy.
