OKX launches 'Exchange OS' to support market creation on X Layer

Cryptocurrency exchange OKX, which has Chinese roots, announced the launch of Exchange OS, a major protocol upgrade on its proprietary Ethereum (ETH) Layer 2 blockchain, X Layer. The new protocol allows developers, institutions, and ecosystem participants to leverage OKX's institutional-grade infrastructure to build three types of markets on X Layer: spot, perpetual futures, and prediction markets. As its first use case, OKX plans to launch a simulation-based 2026 World Cup Prediction Market in June, which will be deployed directly on Exchange OS.
