Technologies Used

• Solidity
• OpenZeppelin
• Hardhat
• Ethers.js

A typical top-level directory layout

Install and Run

1. Clone the repository

git clone

2. Install dependencies

npm install

3. Create a .env file in the root directory and add the following environment variables

MNEMONIC="your mnemonic"
INFURA_API_KEY="your infura api key"
ETHERSCAN_API_KEY="your etherscan api key"

4. Compile the smart contracts

npx hardhat compile

5. Run the tests

npx hardhat test

6. Deploy the smart contracts

npx hardhat run scripts/deploy.js --network rinkeby

Test

For a unit testing smart contract using the command line.
