What is it?

Whirlpools is a concentrated liquidity automated market maker (AMM) built as a smart contract on the Solana blockchain. Liquidity providers can place capital within chosen price ranges, which lets trades execute against deeper liquidity at those prices than a traditional constant-product pool would offer.

The repository contains the Rust on-chain program along with several SDKs. The high-level packages @orca-so/whirlpools for TypeScript and orca_whirlpools for Rust cover most use cases, while lower-level client and core math/quoting packages are available for more specific integrations. A legacy TypeScript SDK remains the option for projects built on Solana Web3.js.

The program is deployed at a fixed address on mainnet and devnet, and the project uses verifiable builds so the on-chain binary's hash can be checked against this source code. Several security firms have audited the program.
