Orca

Orca is the leading user-friendly concentrated-liquidity automated market maker (AMM) on Solana, built around Whirlpools. Liquidity providers concentrate capital within custom price ranges for higher capital efficiency, traders swap tokens with dynamic Adaptive Fees, and creators launch tokens and lock liquidity for launches. Developers and autonomous agents integrate via the open Whirlpools SDKs (TypeScript, Rust, and a Python option) and the read-only Orca Public REST API (api.orca.so) for pool, token, lock, and protocol-wide data.

Orca publishes 3 APIs on the APIs.io network: protocol API, tokens API, and whirlpools API. Tagged areas include Company, Defi Dex, DeFi, DEX, and Solana.

Orca’s developer surface includes documentation, API reference, getting-started guide, support, authentication, sandbox, changelog, and 18 more developer resources.
