Hardhat x Foundry Template

Template repository for getting started quickly with Hardhat and Foundry in one project

Getting Started

• Use Foundry:

forge install
forge test

• Use Hardhat:

npm install
npx hardhat test

Features

• Write / run tests with either Hardhat or Foundry:

forge test
# or
npx hardhat test

• Use Hardhat's task framework

npx hardhat example

• Install libraries with Foundry which work with Hardhat.

forge install rari-capital/solmate # Already in this repo, just an example

Notes

Whenever you install new libraries using Foundry, make sure to update your remappings.txt file by running forge remappings > remappings.txt. This is required because we use hardhat-preprocessor and the remappings.txt file to allow Hardhat to resolve libraries you install with Foundry.

Deployment

• Open a terminal and run a hardhat local node

npx hardhat node --fork https://rpc.moonriver.moonbeam.network

• In another terminal window, run the deployment script

npx hardhat run tasks/deploy.ts --network localnet
