Orca

Orca is a Solana-based decentralized exchange with an automated market maker (AMM) at its core. It has a focus on user interface and ease of use, with a human-centered design. As the largest pure AMM on Solana, Orca places special emphasis on the composability and simplicity of the AMM, and is designed to be a "DeFi lego" (middleware) for the ecosystem.
