Hardhat Moved Plugin

What

This is a hardhat plugin that adds support for the Move language. This plugin extends the compile task with a sub-task to compile contracts written in Move and generate the required artifacts for testing and deployment.

Setting up the Plugin

Right now this plugin requires some manual steps to set up.

Step 1: Install the aptos executable which comes with move tools. Follow the installation instructions, for instance for macOS:

brew install aptos

Step 2: Since hardhat-moved is written in Typescript, it needs to be compiled:

yarn build

With these steps done, you should be able to use this plugin in hardhat-examples, provided that you have already set that up. For now, if you wish to use hardhat-moved in another hardhat project, you would have to add it as a dependency to package.json located in the root of your project, rerun yarn install, and add require("hardhat-move"); to the top of your hardhat.config.ts, similar to what hardhat-examples had done.

Writing Contracts in Move

Move contracts should adhere to the following directory layout

<hardhat project root>
    - contracts
        - MyMovePackage1
            - sources
            - Move.toml
        - MyMovePackage2
            - sources
            - Move.toml

Currently, exactly one contract is generated from each Move package, with the contract name equal to the package name. It should be noted that this is more of a tentative design, and we may add a finer way for the user to specify the package/module-to-contract mapping, potentially allowing custom contract names and defining multiple contracts in the same package.

Development

On one terminal keep building the hardhat plugin whenever a change is saved.

cd sdk/hardhat-moved
yarn watch

On another tab reload the built plugin package and compile the contracts. Make sure to create an .env file using the .env.example template.

cd sdk/hardhat-example
yarn add --force -D file:../hardhat-moved && npx hardhat compile
