Oxygen is a decentralized finance (DeFi) prime brokerage platform that operates on the Solana blockchain and utilizes the Serum on-chain framework. Designed to accommodate hundreds of millions of users, it functions as a cost-effective and scalable protocol, enabling individuals to borrow, lend, and trade with leverage, thereby maximizing their capital potential. With Oxygen, users can generate yield, engage in peer-to-peer borrowing, trade directly from their liquidity pools, and gain leverage against a diverse range of assets. The platform offers an innovative approach to capital management and distinguishes itself from traditional lending protocols through three fundamental characteristics: it is fully decentralized, entirely non-custodial, and operates completely on-chain. All transactions occur directly between users, eliminating any need for a centralized intermediary, which guarantees that Oxygen never has access to your private keys at any stage of the process, ensuring your assets remain secure and under your control. This unique structure not only enhances user privacy but also fosters a truly open financial ecosystem.
