Oxygen

Oxygen is a DeFi prime brokerage service built on Solana and powered by Serum's on-chain infrastructure. Built to support 100s of millions of users, it serves as a permissionless, cheap, and scalable protocol that democratizes borrowing, lending, and trading with leverage and allows you to make the most of your capital.

1. Multiple uses of the same collateral. Oxygen enables you to generate yield on your portfolio through lending out your assets and borrowing other assets at the same time.
2. Cross-collateralization. You can utilize all of your portfolio as collateral when you want to borrow other assets, meaning a lower margin call and liquidation risk for your portfolio.
3. Market-based pricing. Oxygen protocol is order-book based instead of following a pre-set market model that needs to be manually adjusted.

Oxygen is 100% decentralised, 100% non-custodial, and 100% on-chain. All transactions are purely peer-to-peer with no involvement from a centralized operator. Oxygen protocol never has access to your private keys at any point.
