Aave Protocol V3 is a revolutionary decentralized non-custodial liquidity markets protocol that enables users to engage as suppliers or borrowers. In this blog, we will guide you on how to set up and start using Aave Protocol V3. We will also explore some troubleshooting ideas and solutions along the way!

Understanding Aave Protocol V3

Aave allows suppliers to provide liquidity, earning passive income, while borrowers can access funds in either overcollateralized or undercollateralized manners. Think of it as a library where you lend books (liquidity) and borrow books at the same time, with the caveat that you need to return your borrowed books with interest (collateral).

Getting Started

To start using Aave Protocol V3, follow these simple steps:

• Install Aave V3 as an NPM package:

  Use the command below to install:

  npm install @aavecore-v3

• Import in Solidity files:

  Here’s how you import the necessary components in your Solidity files:

  import IPool from @aavecore-v3contractsinterfacesIPool.sol;

• Setting up Your Contract Functions :

  Here’s a simple function to provide liquidity to a pool:

  contract Misc {
      function supply(address pool, address token, address user, uint256 amount) public {
          IPool(pool).supply(token, amount, user, 0);
      }
  }

Setting Up Your Environment

Aave Protocol V3 utilizes Docker Compose for managing configuration and sensitive keys. Begin by following these steps:

1. Install Docker and Docker Compose.
2. Create an environment file named .env and fill in the necessary environment variables:

ALCHEMY_KEY= 
INFURA_KEY= 
# Optional, if you plan to use Tenderly scripts
TENDERLY_PROJECT=
TENDERLY_USERNAME=

Running Tests

To run the complete test suite, follow these terminal commands in a two-terminal setup:

1. In one terminal, start the Docker environment:

docker-compose up

2. In another terminal, connect to your environment:

docker-compose exec contracts-env bash

3. Run the tests:

npm run test

Troubleshooting Common Issues

If you run into any issues while setting up or using Aave Protocol V3, try the following troubleshooting tips:

• Ensure that Docker and Docker Compose are correctly installed and functioning.
• Verify that your .env file has the correct syntax and variable names.
• For issues with tests failing, check that you have the latest code updates from the Aave V3 Origin Repository here.
• If you get stuck or have questions, visit the Discord channel or the Governance Forum to connect with the community.
