O2 is a fully onchain spot order-book decentralized exchange built on Fuel Network, incubated by Fuel Labs as an internal venture to demonstrate the throughput capabilities of the Fuel blockchain. O2's Twitter Score is 11 out of 1000 as of September 2026, ranking #89,333 among 486,860 tracked accounts.
O2 operates as a central limit order book placed entirely onchain, distinguishing it from hybrid or off-chain order-matching designs common among decentralized exchanges. The platform advertises zero gas fees, institutional-grade spreads, and trade execution under 20 milliseconds, positioning it as a high-performance alternative for spot traders. A security review by Hexens, dated August 2025, is publicly listed in the project's open repository for external audit access.
O2 expanded its offering with the launch of o2 Turbo, a prop-trading program that provides immediate access to funded spot-trading accounts of $2,500, $5,000, or $10,000, with account durations ranging from six hours to one month. The program requires no evaluation period and no profit split, charges a fixed upfront premium with refundable margin, and allows traders to retain the full profit generated. O2 has published 1,420 posts on the platform.
