Dependencies

Node.js

First install Node.js and npm. Run the following command to install yarn:

npm install --global yarn

Foundry

Install foundryup, the Foundry toolchain installer:

curl -L https://foundry.paradigm.xyz | bash

If you do not want to use the redirect, feel free to manually download the foundryup installation script from here.

Then, run foundryup in a new terminal session or after reloading PATH.

Other ways to install Foundry can be found here.

Hardhat

Run the following command to install Hardhat and other dependencies.

yarn install

Build

  • Run git submodule update --init --recursive to initialize git submodules.
  • Run yarn prettier:solidity to run linting in fix mode, will auto-format all solidity codes.
  • Run yarn prettier to run linting in fix mode, will auto-format all typescript codes.
  • Run yarn prepare to install the precommit linting hook.
  • Run forge build --evm-version cancun to compile contracts with foundry.
  • Run npx hardhat compile to compile with hardhat.
  • Run forge test --evm-version cancun -vvv to run foundry units tests. It will compile all contracts before running the unit tests.
  • Run npx hardhat test to run integration tests. It may not compile all contracts before running, it's better to run npx hardhat compile first.
