Foundry UUPS Upgradeable Contracts

This is a section of the Cyfrin Foundry Solidity Course.

⭐️ (4:47:00) | Lesson 13: Foundry Upgradable Contracts

*This is for demo purposes only. Upgradeable contracts are a menance and in general should be avoided for

Getting Started

Requirements

  • git
    • You'll know you did it right if you can run git --version and you see a response like git version x.x.x
  • foundry
    • You'll know you did it right if you can run forge --version and you see a response like forge 0.2.0 (816e00b 2023-03-16T00:05:26.396218Z)

Quickstart

git clone https://github.com/Cyfrin/foundry-upgrades-f23
cd foundry-upgrades-f23
forge build

Optional Gitpod

If you can't or don't want to run and install locally, you can work with this repo in Gitpod. If you do this, you can skip the clone this repo part.

Open in Gitpod

Usage

Start a local node

make anvil

Deploy

This will default to your local node. You need to have it running in another terminal in order for it to deploy.

make deploy

Deploy - Other Network

See below

Testing

forge test

Test Coverage

forge coverage

and for coverage based testing:

forge coverage --report debug

Deployment to a testnet or mainnet

  1. Setup environment variables

You'll want to set your SEPOLIA_RPC_URL and PRIVATE_KEY as environment variables. You can add them to a .env file, similar to what you see in .env.example.

  • PRIVATE_KEY: The private key of your account (like from metamask). NOTE: FOR DEVELOPMENT, PLEASE USE A KEY THAT DOESN'T HAVE ANY REAL FUNDS ASSOCIATED WITH IT.
  • SEPOLIA_RPC_URL: This is url of the goerli testnet node you're working with. You can get setup with one for free from Alchemy

Optionally, add your ETHERSCAN_API_KEY if you want to verify your contract on Etherscan.

  1. Get testnet ETH

Head over to faucets.chain.link and get some tesnet ETH. You should see the ETH show up in your metamask.

  1. Deploy
make deploy ARGS="--network sepolia"

Estimate gas

You can estimate how much gas things cost by running:

forge snapshot

And you'll see and output file called .gas-snapshot

Formatting

To run code formatting:

forge fmt
