Orca

Orca is a decentralized exchange (DEX) and liquidity protocol built primarily on Solana and the Eclipse Layer 2 blockchain. It offers a user-friendly platform for swapping tokens, providing liquidity, and launching new tokens. Orca’s core innovation is its Concentrated Liquidity Automated Market Maker (CLMM) model, implemented through the Whirlpool program. This model allows liquidity providers to concentrate their capital within specific price ranges, improving capital efficiency and reducing slippage for traders, especially on larger trades. Orca’s design targets a broad audience including traders, liquidity providers, token creators, and ecosystem builders.

Founded in 2021 by a small team in Tokyo, Orca has grown into one of Solana’s leading DEXs with a reputation for security and transparency, having maintained zero hacks over four years. Orca’s ethos emphasizes professionalism, principled development, and community engagement, reflected in its open-source smart contracts, audited code, and active governance via the Orca DAO. The platform supports a variety of SDKs in Rust and TypeScript, enabling developers to integrate and build on top of Orca’s liquidity infrastructure easily.

Orca’s v2 UI launched in 2024, enhancing usability for four distinct user groups: traders benefit from low slippage and price accuracy via integrated Jupiter price comparison; liquidity providers can manage both full-range and concentrated liquidity positions with advanced tools; token creators can launch permissionless pools for any SPL token; and builders can leverage Orca’s audited smart contracts and SDKs to integrate liquidity into their projects. Orca also supports governance participation through ORCA token holder voting, enabling community-driven protocol evolution. Developers can get started by exploring Orca’s comprehensive documentation, SDKs, and example projects available on GitHub.
