Whirpools is an open-source concentrated liquidity AMM contract on the Solana blockchain. This repository contains the Rust smart contract as well as the Typescript SDK (@orca-so/whirlpools-sdk) to interact with a deployed program.

The contract has been audited by Kudelski and Neodyme.

• Anchor 0.20.1
• Solana 1.9.3
• Rust 1.59.0

Install Anchor using instructions found here.

Set up a valid Solana keypair at the path specified in the wallet in Anchor.toml to do local testing with anchor test flows.

$NODE_PATH must be set to the node_modules directory of your global installs. For example, using Node 16.10.0 installed through nvm, the $NODE_PATH is the following:

$ echo $NODE_PATH
/Users/<home_dir>/.nvm/versions/node/v16.10.0/lib/node_modules

Instructions on how to interact with the Whirlpools contract is documented in the Orca Developer Portal.

• Run "cargo test --lib" to run Rust unit tests

Use the SDK to interact with a deployed Whirlpools program via Typescript.

In your package, run:

yarn add `@orca-so/whirlpools-sdk`
yarn add "@project-serum/anchor"
yarn add "decimal.js"

Read instructions on how to use the SDK on the Orca Developer Portal.

In the whirlpools/sdk folder, run:
