Boilerplate for hybrid development using Hardhat and Foundry

Uses https://github.com/wighawag/template-ethereum-contracts as base template. Adds nomicfoundation/hardhat-foundry npm package and divides tests into hardhat and foundry. foundry.toml is modified with several configurations including remappings, solc version test directory.

INSTALL

yarn

TEST

There are 3 flavors of tests: hardhat, dapptools and forge

hardhat

• One using hardhat that can leverage hardhat-deploy to reuse deployment procedures and named accounts:

yarn test:hardhat

foundry

yarn test:foundry

This require the installation of forge (see foundry)

SCRIPTS

Here is the list of npm scripts you can execute:

Some of them relies on ./_scripts.js to allow parameterizing it via command line argument (have a look inside if you need modifications)

yarn prepare

As a standard lifecycle npm script, it is executed automatically upon install. It generate config file and typechain to get you started with type safe contract interactions

yarn format and yarn format:fix

These will format check your code. the :fix version will modifiy the files to match the requirement specified in .prettierrc.

yarn compile

These will compile your contracts

yarn void:deploy

This will deploy your contracts on the in-memory hardhat network and exit, leaving no trace. quick way to ensure deployments work as intended without consequences

yarn test [mocha args...]

These will execute your tests using mocha. you can pass extra arguments to mocha

yarn coverage

These will produce a coverage report in the coverage/ folder

yarn gas

These will produce a gas report for function used in the tests

yarn dev

These will run a local hardhat network on localhost:8545 and deploy your contracts on it. Plus it will watch for any changes and redeploy them.

yarn local:dev

This assumes a local node it running on localhost:8545. It will deploy your contracts on it. Plus it will watch for any changes and redeploy them.

yarn execute <network> <file.ts> [args...]

This will execute the script <file.ts> against the specified network

yarn deploy <network> [args...]

This will deploy the contract on the specified network.

Behind the scene it uses hardhat deploy command so you can append any argument for it

yarn export <network> <file.json>

This will export the abi+address of deployed contract to <file.json>

yarn fork:execute <network> [--blockNumber <blockNumber>] [--deploy] <file.ts> [args...]

This will execute the script <file.ts> against a temporary fork of the specified network

if --deploy is used, deploy scripts will be executed

yarn fork:deploy <network> [--blockNumber <blockNumber>] [args...]

This will deploy the contract against a temporary fork of the specified network.

Behind the scene it uses hardhat deploy command so you can append any argument for it

yarn fork:test <network> [--blockNumber <blockNumber>] [mocha args...]

This will test the contract against a temporary fork of the specified network.

yarn fork:dev <network> [--blockNumber <blockNumber>] [args...]

This will deploy the contract against a fork of the specified network and it will keep running as a node.

Behind the scene it uses hardhat node command so you can append any argument for it
