Orca

Orca is recognized as one of the most user-friendly decentralized exchanges (DEXs) on the Solana blockchain. It stands out as one of the first general-purpose Automated Market Makers (AMMs) launched on Solana. Orca offers users the ability to swap assets, provide liquidity, and earn yield through a straightforward interface. It also serves as a "money-lego" for projects, allowing them to integrate swapping, farming, or on-chain data into their decentralized applications (dApps). Orca's primary goal is to bring decentralized finance (DeFi) to a broader audience by providing easy-to-use financial tools​​​.

Orca operates as a Solana-based pure AMM DEX with its own liquidity pools, distinguishing itself from order book-based exchanges on Solana due to its simplicity and scalability. The platform offers features like token swapping using its pools, liquidity provision to Orca’s pools in exchange for a portion of trading costs, and an Aquafarm Yield Farming Program. This program allows liquidity providers in certain pools to earn both trading fees and ORCA tokens. Orca also utilizes a token-swap smart contract that has been audited and is available for integration, supporting the creation and trading of custom Orca pools by communities, projects, and market participants. Additionally, being built on the Solana blockchain, Orca provides fast exchanges with low fees​.
