What is Oxygen (OXY) ?

Oxygen is a DeFi prime brokerage service powered by Serum's on-chain infrastructure and based onto Solana. It's a permissionless and scalable protocol that allows users to make the most of their money by democratizing borrowing, lending, and trading with leverage.Oxygen's goal is to convert the current financial system into one that is more accessible, fair, and powerful than ever thought possible. The initial phase of Oxygen is a borrow-lending infrastructure based on pools. Following that, they want to offer volatility trading agreements and structured product features, allowing developers to design their own structured products. Their ultimate goal is to recreate marketplace-like business units that already exist within investment banks and make them available to the general public.
