indu4.0 ERC-20 Smart Contract

Installation

It is recommended to install Yarn through the npm package manager, which comes bundled with Node.js when you install it on your system. It is recommended to use a Node.js version >= 16.0.0.

Once you have npm installed, you can run the following both to install and upgrade Yarn:

npm install --global yarn

After having installed Yarn, simply run:

yarn install

Compilation

To compile the contract, it is important that you have installed the project correctly, as we use external dependencies and contracts. Use the following command to compile the contracts:

yarn compile

Running Deployments

Example Goerli:

yarn deploy:goerli

Example Ethereum Mainnet:

yarn deploy:ethmain

Running CREATE2 Deployments

yarn xdeploy

This repository uses the xdeploy Hardhat plugin. Check out the documentation for more information on the specifics of the deployments.

.env File

In the .env file place the private key of your wallet in the PRIVATE_KEY section. This allows secure access to your wallet to use with both testnet and mainnet funds during Hardhat deployments. For more information on how this works, please read the documentation of the npm package dotenv.

Unit Tests

Since we build the ERC-20 smart contract on top of the audited OpenZeppelin node modules, there is no further requirement to write dedicated tests for these modules.

You can run the tests with

yarn test:hh

Etherscan Verification

Change the contract address to your contract after the deployment has been successful. This works for both testnet and mainnet. You will need to get an API key from etherscan, snowtrace etc.

Example:

npx hardhat verify --network ethMain <DEPLOYED_CONTRACT_ADDRESS> --constructor-args verify-args.ts
