Welcome to your guide on setting up Yearn Vault Contracts! This article will take you through a straightforward process to get everything you need for developing smart contracts tailored to the Yearn protocol. Whether you’re an experienced developer or just starting, this guide will help you navigate the installation and setup with ease.

Requirements

Before diving into the installation, ensure you have the following prerequisites:

• Python 3.8 local development environment
• Node.js 10.x development environment for Ganache
• Brownie local environment
• Local environment variables for Etherscan API and Infura
• Local Ganache environment

Installation Steps

To harness the powerful features of Yearn Vault Contracts, follow these steps:

1. Clone the Repository

Start by pulling the repository from GitHub and installing its dependencies:

git clone https://github.com/yearn/yearn-vaults
cd yearn-vaults
yarn install --lock-file

2. Compile the Smart Contracts

Compile the smart contracts using Brownie:

brownie compile

3. Windows Users

If you’re using Windows, take special notes:

• Consider using the Windows Subsystem for Linux (WSL) for a smoother experience.
• Follow Linux instructions from a Linux terminal, except for VSCode installations.

4. Install Full Environment

Ensure you have VSCode, its extensions, Node.js, Ganache, and other dependencies installed as outlined in the README.

Understanding the Code Structure

Imagine the process of setting up these contracts as preparing a recipe. You are gathering all the ingredients (dependencies), ensuring they are fresh (up-to-date), and laying them out in the correct order (installing in sequence). The more precise your preparation, the smoother your cooking (development) will go. Moving step-by-step ensures you don’t miss any essential ingredients needed to bake your smart contract to perfection!

Running Tests

To verify everything is functioning fine, run the tests as follows:

brownie test tests/functional -n auto

Troubleshooting

If you encounter issues, here are some troubleshooting tips:

• Ensure all environment variables (ETHERSCAN_TOKEN, WEB3_INFURA_PROJECT_ID) are set correctly.
• Check that you have the right versions of Python and Node.js installed.
• If you hit a dependency error during installation, try using --ignore-engines flag.
• Read the error messages carefully, as they often indicate exactly what went wrong.
