In the ever-evolving world of decentralized finance (DeFi), understanding protocols like Aave is crucial. This blog will walk you through the process of creating a liquidation script for the Aave protocol, providing you with clear steps and friendly instructions. So, let’s dive into the world of DeFi and learn how to execute a liquidation!

What is Liquidation in Aave?

Liquidation is the process by which an asset is sold to repay a loan when the borrower’s collateral falls below a certain threshold. Aave ensures that its lending protocol remains solvent, and liquidators play an essential role in this mechanism.

Installation Instructions

Before we start, ensure you have the necessary environment set up. Follow the steps below:

• Create the .env file by executing the following command:

mv .env.template .env

• Next, fill in the required variables in the .env file. This will include your Aave credentials and any relevant configuration for your script.
• Install the dependencies required for the application by running:

npm install

Integration Testing

This is an integration test that calls external resources in the Ropsten network. To get started, you’ll need to:

• Fill in the test data required for your script.
• Execute the test using the command:

npm test

Executing Liquidation

Now that everything is set up, it’s time to execute the liquidation. Follow these steps:

• Open app.js and fill in the necessary data for your liquidation script. This includes the details of the asset and the target address.
• To execute your liquidation script, run the following command:

npm start

Understanding the Code: An Analogy

Imagine you are a bank manager who has to ensure that every loan is appropriately secured. You have a list of customers who have borrowed money, along with the collateral they provided. If one customer’s collateral decreases in value to the point where it no longer covers their loan, you must take action to protect the bank’s interests. In our context, the liquidation script acts like a diligent bank manager—constantly checking the collateral and, when necessary, executing a sale to recover the amount owed.

Troubleshooting

If you encounter issues during the installation or execution, consider the following troubleshooting ideas:

• Ensure your .env file contains correct and complete data.
• Verify that your npm dependencies are installed without errors.
• Check your internet connection, especially when calling external resources during testing.
• If errors persist, consult the documentation or community forums for insights.
