Development

Clonning and running on a local machine

yarn install
yarn dev

Testing

Running tests

npx hardhat test
npx hardhat test test/CommunaToken.ts --grep 'should transfer ownership'

Deployment

To try out Etherscan verification, you first need to deploy a contract to an Ethereum network that's supported by Etherscan, such as Goerli or Polygon.

In this project, copy the .env.example file to a file named .env, and then edit it to fill in the details. Enter your Etherscan API key, your Ropsten node URL (eg from Alchemy), and the private key of the account which will send the deployment transaction. With a valid .env file in place, first deploy your contract:

Goerli

npx hardhat run --network goerli scripts/deployToken.ts
npx hardhat run --network goerli scripts/deployRouter.ts
npx hardhat run --network goerli scripts/pay.ts
npx hardhat run --network goerli scripts/mint.ts
npx hardhat run --network goerli scripts/airdrop.ts

Polygon

npx hardhat run --network polygon scripts/deployToken.ts
npx hardhat run --network polygon scripts/deployRouter.ts
npx hardhat run --network polygon scripts/pay.ts
npx hardhat run --network polygon scripts/mint.ts
npx hardhat run --network polygon scripts/airdrop.ts

Then, copy the deployment address and paste it in to replace ROUTER_ADDRESS and TOKEN_ADDRESS in this command:

Goerli

npx hardhat verify --network goerli TOKEN_ADDRESS
npx hardhat verify --network goerli ROUTER_ADDRESS TOKEN_ADDRESS

Polygon

npx hardhat verify --network polygon TOKEN_ADDRESS
npx hardhat verify --network polygon ROUTER_ADDRESS TOKEN_ADDRESS

Commands

npx hardhat run --network goerli scripts/pay.ts
npx hardhat run --network goerli scripts/mint.ts
npx hardhat run --network goerli scripts/airdrop.ts

Performance optimizations

For faster runs of your tests and scripts, consider skipping ts-node's type checking by setting the environment variable TS_NODE_TRANSPILE_ONLY to 1 in hardhat's environment. For more details see the documentation.

Advanced Sample Hardhat Project

This project demonstrates an advanced Hardhat use case, integrating other tools commonly used alongside Hardhat in the ecosystem.

The project comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts. It also comes with a variety of other tools, preconfigured to work with the project code.

Try running some of the following tasks:

npx hardhat accounts
npx hardhat compile
npx hardhat clean
npx hardhat test
npx hardhat node
npx hardhat help
REPORT_GAS=true npx hardhat test
npx hardhat coverage
npx hardhat run scripts/deploy.ts
TS_NODE_FILES=true npx ts-node scripts/deploy.ts
npx eslint '**/*.{js,ts}'
npx eslint '**/*.{js,ts}' --fix
npx prettier '**/*.{json,sol,md}' --check
npx prettier '**/*.{json,sol,md}' --write
npx solhint 'contracts/**/*.sol'
npx solhint 'contracts/**/*.sol' --fix
