⭐️ (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
git --version
and you see a response like git version x.x.x
forge --version
and you see a response like forge 0.2.0 (816e00b 2023-03-16T00:05:26.396218Z)
git clone https://github.com/Cyfrin/foundry-upgrades-f23
cd foundry-upgrades-f23
forge build
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.
make anvil
This will default to your local node. You need to have it running in another terminal in order for it to deploy.
make deploy
forge test
forge coverage
and for coverage based testing:
forge coverage --report debug
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 AlchemyOptionally, add your ETHERSCAN_API_KEY
if you want to verify your contract on Etherscan.
Head over to faucets.chain.link and get some tesnet ETH. You should see the ETH show up in your metamask.
make deploy ARGS="--network sepolia"
You can estimate how much gas things cost by running:
forge snapshot
And you'll see and output file called .gas-snapshot
To run code formatting:
forge fmt
