Orca

## What Is Orca? Orca touts itself as the "easiest, fastest, and most user-friendly cryptocurrency exchange on the Solana blockchain." Being one of the first automated [market makers](https://coinmarketcap.com/alexandria/article/what-are-automated-market-makers) (AMM) launched on [Solana](https://coinmarketcap.com/alexandria/article/solana), the decentralized exchange (DEX) maintains its own [liquidity pools](https://coinmarketcap.com/alexandria/glossary/liquidity-pool). It allows users to swap assets, participate in yield farming, and provide liquidity. The platform leverages Solana’s quick transactions and low fees. On one hand, users can perform low-fee token trades. On the other, they can provide [concentrated liquidity](https://coinmarketcap.com/alexandria/glossary/concentrated-liquidity) to the platform to earn a share of trading fees. ### Who Are the Founders of Orca?
