Aave V3 Deployments

npm (scoped)

This Node.js repository contains the configuration and deployment scripts for the Aave V3 protocol core and periphery contracts. The repository makes use of hardhat and hardhat-deploy tools to facilitate the deployment of Aave V3 protocol.

Requirements

Getting Started

  1. Install Node.JS dependencies:

    npm i

  2. Compile contracts before running any other command, to generate Typechain TS typings:

    npm run compile

How to deploy Aave V3 in testnet network

To deploy Aave V3 in a Testnet network, copy the .env.example into a .env file, and fill the environment variables MNEMONIC, and ALCHEMY_KEY.

cp .env.example .env

Edit the .env file to fill the environment variables MNEMONIC, ALCHEMY_KEY and MARKET_NAME. You can check all possible pool configurations in this file.

nano .env

Run the deployments scripts and specify which network & aave market configs you wish to deploy.

HARDHAT_NETWORK=goerli npx hardhat deploy

How to deploy Aave V3 in fork network

You can use the environment variable FORK with the network name to deploy into a fork.

FORK=main MARKET_NAME=Aave npx hardhat deploy

How to integrate in your Hardhat project

You can install the pollum-io/lending-deploy package in your Hardhat project to be able to import deployments with hardhat-deploy and build on top of Aave in local or testnet network.

To make it work, you must install the following packages in your project:

npm i --save-dev pollum-io/lending-deploy @aave/core-v3 @aave/periphery-v3

Then, proceed to load the deploy scripts adding the externals field in your Hardhat config file at hardhat.config.js|ts.

# Content of hardhat.config.ts file

export default hardhatConfig: HardhatUserConfig = {
   {...},
   external: {
    contracts: [
      {
        artifacts: 'node_modules/pollum-io/lending-deploy/artifacts',
        deploy: 'node_modules/pollum-io/lending-deploy/dist/deploy',
      },
    ],
  },
}

After all is configured, you can run npx hardhat deploy to run the scripts or you can also run it programmatically in your tests using fixtures:

import {getPoolAddressesProvider} from 'pollum-io/lending-deploy';

describe('Tests', () => {
   before(async () => {
      // Set the MARKET_NAME env var
      process.env.MARKET_NAME = "Aave"

      // Deploy Aave V3 contracts before running tests
      await hre.deployments.fixture(['market', 'periphery-post']);`
   })

   it('Get Pool address from AddressesProvider', async () => {
      const addressesProvider = await getPoolAddressesProvider();

      const poolAddress = await addressesProvider.getPool();

      console.log('Pool', poolAddress);
   })
})

How to verify your contract deployments

npx hardhat --network XYZ etherscan-verify --api-key YZX
