Are you ready to dive into the world of decentralized finance? The Hifi fixed-rate, fixed-term lending protocol is a fascinating project, and setting it up is easier than you think! In this article, we will guide you step-by-step on how to set it up, contribute to it, and troubleshoot common issues.

Getting Started with Hifi

Before you embark on this journey, ensure that you have the following software prerequisites installed on your machine:

• Git
• Node.js
• Yarn

Additionally, a familiarity with Solidity, TypeScript, and Hardhat will be beneficial.

Setting Up Hifi

Once you have the prerequisites ready, follow these steps:

1. Set the version of Node to use:

   bash
   $ nvm use
   

2. Install the dependencies:

   bash
   $ yarn install
   

3. Build the packages:

   bash
   $ yarn build
   

4. Create a .env file and follow the .env.example file to add the requisite environment variables, then run the watcher:

   bash
   $ yarn watch:ts
   

Now you’re ready to start making changes! This protocol is organized as a monorepo, meaning that different packages such as @hifi/amm for market-making and @hifi/protocol for the core lending system reside under the same repository. Think of it like a well-managed library where each book (or package) serves a specific purpose while still being part of a bigger collection.
