We would like to first acknowledge that PAC Finance is originally a fork of the Aave v3 codebase. We are grateful for the foundation provided by Aave and are committed to contributing to the ongoing development and innovation within the DeFi ecosystem.

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

• Node.js >= 16
• Alchemy key
  • If you use a custom RPC node, you can change the default RPC provider URL at ./helpers/hardhat-config-helpers.ts:25.
• Etherscan API key (Optional)

1. Install Node.JS dependencies:

   npm i
   

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

   npm run compile
   

To deploy Pac Finance 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

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

FORK=main MARKET_NAME=Aave npx hardhat deploy

You can install the @aave/deploy-v3 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 @aave/deploy-v3 @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/@aave/deploy-v3/artifacts',
        deploy: 'node_modules/@aave/deploy-v3/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 '@aave/deploy-v3';

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

      // Deploy Pac Finance 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);
   })
})

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