⭐️ (2:37:02) | Lesson 8: HTML Fund Me
This is a minimalistic example what you can find in the metamask docs.
- git
- You'll know you've installed it right if you can run:
git --version
- You'll know you've installed it right if you can run:
- Metamask
- This is a browser extension that lets you interact with the blockchain.
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.
- Clone the repo
git clone https://github.com/Cyfrin/html-fund-me-f23
cd html-fund-me-f23
- Run the file.
You can usually just double click the file to "run it in the browser". Or you can right click the file in your VSCode and run "open with live server".
And you should see a small button that says "connect".
Hit it, and you should see metamask pop up.
If you want to execute a transaction follow this:
Make sure you have the following installed:
- You'll need to open up a second terminal and run:
git clone https://github.com/Cyfrin/foundry-fund-me-f23
cd foundry-fund-me-f23
make build
make anvil
Then, in a second terminal
make deploy
This will deploy a sample contract and start a local hardhat blockchain.
- Update your
constants.jswith the new contract address.
In your constants.js file, update the variable contractAddress with the address of the deployed "FundMe" contract. You'll see it near the top of the hardhat output.
- Connect your metamask to your local hardhat blockchain.
PLEASE USE A METAMASK ACCOUNT THAT ISNT ASSOCIATED WITH ANY REAL MONEY. I usually use a few different browser profiles to separate my metamasks easily.
In the output of the above command, take one of the private key accounts and import it into your metamask.
Additionally, add your localhost with chainid 31337 to your metamask.
- Refresh the front end, input an amount in the text box, and hit
fundbutton after connecting
