Perennial is a decentralized derivatives protocol that offers a straightforward trading experience, a flexible and capital-efficient model for providing liquidity, and a primitive for developers to create DeFi derivatives easily. Perennial acts as a peer-to-pool derivatives AMM that perpetually offers to take the other side of any Taker's position at the oracle price, in exchange for a funding rate that fluctuates based on the utilization of the liquidity pool (similar to Compound and Aave).
