Installation

The CoW Protocol contracts package enables developers to integrate CoW Protocol functionality into their projects.

Package Installation

npm install @cowprotocol/contracts

yarn add @cowprotocol/contracts

pnpm add @cowprotocol/contracts

Peer Dependencies

The package requires ethers version 5.4.0 or higher as a peer dependency:

npm install ethers@^5.4.0

The package targets ethers v5. Compatibility with ethers v6 is not assured.

Basic Setup

import {
  Order,
  OrderKind,
  signOrder,
  SigningScheme,
} from "@cowprotocol/contracts";

TypeScript Support

The package provides comprehensive TypeScript type definitions for all interfaces, enums, and functions. Contract artifacts with deployment information are accessible via a networks.json file.

Building from Source

For developers preferring to build from source:

git clone https://github.com/cowprotocol/contracts.git
cd contracts
yarn install
yarn build

The build generates both CommonJS and ESM modules.
