Solidity Template

My favourite setup for writing Solidity smart contracts.

• Hardhat: compile and run the smart contracts on a local development network
• TypeChain: generate TypeScript types for smart contracts
• Ethers: renowned Ethereum library and wallet implementation
• Waffle: tooling for writing comprehensive smart contract tests
• Solhint: linter
• Solcover: code coverage
• Prettier Plugin Solidity: code formatter

This is a GitHub template, which means you can reuse it as many times as you want. You can do that by clicking the "Use this template" button at the top of the page.

Etherscan verification

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

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:

hardhat run --network ropsten scripts/sample-script.ts

Then, run the verify task, passing the address of the contract replacing DEPLOYED_CONTRACT_ADDRESS, the network where it's deployed by replacing NETWORK, and the constructor arguments that were used to deploy it (if any):

npx hardhat verify --network NETWORK DEPLOYED_CONTRACT_ADDRESS "Constructor argument 1"

Usage

Pre Requisites

Before running any command, make sure to install dependencies:

$ yarn install

Compile

Compile the smart contracts with Hardhat:

$ yarn compile

Run a local node

Expose a JSON-RPC interface to Hardhat Network

$ yarn start

TypeChain

Compile the smart contracts and generate TypeChain artifacts:

$ yarn typechain

Lint Solidity

Lint the Solidity code:

$ yarn lint:sol

Lint TypeScript

Lint the TypeScript code:

$ yarn lint:ts

Test

Run the Mocha tests:

$ yarn test

Coverage

Generate the code coverage report:

$ yarn coverage

Report Gas

See the gas usage per unit test and average gas per method call:

$ yarn test:gas

Clean

Delete the smart contract artifacts, the coverage reports and the Hardhat cache:

$ yarn clean

Deploy

Deploy the contracts to Hardhat Network:

$ yarn deploy

Deploy the contracts to a specific network, such as the Mainnet testnet:

$ yarn deploy:mainnet

Deployed contract addresses and other information regarding deployments can be found in the .openzeppelin folder

Syntax Highlighting

If you use VSCode, you can enjoy syntax highlighting for your Solidity code via the vscode-solidity extension. The recommended approach to set the compiler version is to add the following fields to your VSCode user settings:

{
    "solidity.compileUsingRemoteVersion": "v0.8.4+commit.c7e474f2",
    "solidity.defaultCompiler": "remote"
}

Where of course v0.8.4+commit.c7e474f2 can be replaced with any other version.
