Solidity Demo

I am learning solidity, this repository store some solidity demos which I learned.

Some demos contain unit testing by hardhat, here is the quick installation of the hardhat.

npm init
npm install --save-dev hardhat
npx hardhat

After the installation, move *.sol file to contract folder and *.js to test folder.

Start the unit testing with npx hardhat test command.

## Run unit testing script
