what's O2?

O2 is a high-performance trading platform built on the Fuel network, an Ethereum Layer 2 rollup designed for scalable and efficient blockchain applications. It features the fastest Central Limit Order Book (CLOB) in the crypto space, emphasizing privacy-enabled spot trading as its initial focus. The platform leverages Fuel's parallelized execution and low-latency confirmations (sub-100ms) to deliver real-time trading experiences without compromising Ethereum's security guarantees. Privacy is integrated at the protocol level, allowing users to trade spot assets while protecting order details and positions from public visibility. O2 plans to expand beyond spot trading to include perpetuals (perps), lending, and other DeFi primitives, all optimized for high throughput and cost efficiency. By utilizing Fuel's modular stack, including data availability on EigenDA, O2 removes bottlenecks in traditional order books, enabling seamless scalability for institutional and retail traders alike. The project aligns with the broader trend of app-specific sequencing and state-minimized execution in rollups, positioning O2 as a specialized venue for advanced trading use cases within the Ethereum ecosystem.
