OKX launched Exchange OS, a platform that lets users build and operate custom crypto trading markets on-chain
Crypto exchange OKX has released a platform that allows users to create and operate their own spot, perpetuals, and outcomes markets, choosing which assets to list and how the market is governed. The platform, called Exchange OS, is built on X Layer, OKX's Ethereum layer 2, and draws on the same underlying infrastructure that runs OKX's own exchange. OKX founder and CEO Star Xu announced the launch in a blog post on Tuesday.
Xu said Exchange OS is designed to address what he called the fragmented infrastructure problem in crypto-based finance. "While blockchain enabled open asset issuance, the infrastructure for trading, settlement, margining, and liquidity remains siloed across disconnected venues and applications," he said. Exchange OS is intended to consolidate those functions onto shared rails.
The platform integrates on-chain matching, margining, liquidation, settlement, and risk management directly into X Layer. By running these functions on a single infrastructure stack, multiple markets can theoretically draw from the same capital pool simultaneously, rather than operating as isolated systems with separate liquidity. Xu said this shared execution environment is central to what separates Exchange OS from existing approaches.
Exchange OS is currently in the first of three planned rollout phases. The initial phase is limited to select partners who will build on the platform ahead of a broader public opening scheduled for the third quarter of 2026. Protocol improvements are planned for the fourth quarter of 2026 and beyond. The first market built on Exchange OS is a predictions-style market for the FIFA World Cup.
Users can also create their own assets, oracle systems, revenue structures, and compliance frameworks through the platform. Exchange OS supports both permissioned and permissionless configurations, allowing a regulated institution to run a fully Know Your Customer (KYC)-compliant venue alongside a permissionless market on the same infrastructure. Xu said this flexibility is intended to serve both institutional operators and Web3-native teams without requiring separate systems.
OKX said the platform operates at millisecond-level latency and can process up to 300,000 transactions per second. The exchange has been expanding its product range beyond spot and derivatives trading, with recent moves into tokenization and infrastructure for AI agent transactions. Exchange OS continues that direction, positioning the exchange as a building platform rather than a standalone trading venue.
