Hardhat UUPS Upgradeable Smart Contracts Boilerplate

This project serves as boilerplate for getting started quickly working with UUPS upgradeable smart contracts on a Hardhat environment. It is based on the OpenZeppelin UUPSUpgradeable proxy model enabling interaction with multisig contracts through either an Ownable or AccessControl role-based mechanism. It utilise the @openzeppelin/hardhat-upgrades plugin to manage the upgrades and @openzeppelin/defender-admin-client to programmatically create any multisig proposal.

Features

This repository includes the following features:

• UUPS Upgradeability: smart contracts templates based on the OpenZeppelin UUPS proxy mechanism.
• Ownable or AccessControl role-based multisig: choose between an Ownable or AccessControl role-based approach for managing multisig contracts.
• Hardhat Upgrades Plugin: streamline the smart contracts upgrade process using the hardhat-upgrades plugin.
• Defender Admin Client integration: Enhance security with programmatically created multisig proposals using the defender-admin-client library.

Key components:

• @openzeppelin/hardhat-upgrades: A plugin that facilitates the management of smart contract upgrades in the Hardhat environment.
• @openzeppelin/defender-admin-client: This library enables the programmatically creation of multisig proposals, adding an extra layer of security and control.
• @nomicfoundation/hardhat-verify: Allows to programmatically verify any contract on one of the supported chains.

Configuration

All essential configurations for using this boilerplate are conveniently organized under the config folder:

• index.ts: manage networks configurations by updating the networksConfig object. Add or remove chains effortlessly to tailor the boilerplate to your needs.
• deployments.ts: serves as a central repository for all your deployments. Every deployment you perform will be automatically recorded by chain within this file for quick reference and tracking.
• multisigs.ts: handle multisig contracts by updating the multisigs object. Add or remove multisig contract addresses by chain to adapt to your project's requirements.
• roles.ts: AccessControl role management using the provided pattern under the ROLES object. Add or remove roles with ease, ensuring a streamlined approach to role-based access.

Quick start

1. Clone this repository to your local machine:

git clone https://github.com/gabrielstoica/hardhat-upgrades

2. Change directory to the cloned project:

cd hardhat-upgrades

3. Install dependencies:

yarn install

4. Create a new .env based on the .env.example with your API keys and secrets
5. Compile the contracts:

yarn hardhat compile

6. Deploy the Box contract to a testnet or mainnet using the deploy.ts script:

yarn hardhat run scripts/deploy.ts --network YOUR_NETWORK
