- Thank you!
- git
- You'll know you did it right if you can run
git --version
and you see a response likegit version x.x.x
- You'll know you did it right if you can run
- Nodejs
- You'll know you've installed nodejs right if you can run:
node --version
and get an ouput likevx.x.x
- You'll know you've installed nodejs right if you can run:
- Yarn instead of
npm
- You'll know you've installed yarn right if you can run:
yarn --version
And get an output likex.x.x
- You might need to install it with npm
- You'll know you've installed yarn right if you can run:
git clone https://github.com/PatrickAlphaC/hardhat-erc20-fcc
cd hardhat-erc20-fcc
yarn
git checkout typescript
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.
Deploy:
yarn hardhat deploy
- Setup environment variabltes
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.- You can learn how to export it here.
SEPOLIA_RPC_URL
: This is url of the sepolia testnet node you're working with. You can get setup with one for free from Alchemy
- Get testnet ETH
Head over to faucets.chain.link and get some tesnet ETH. You should see the ETH show up in your metamask.
- Deploy
yarn hardhat deploy --network sepolia
If you deploy to a testnet or mainnet, you can verify it if you get an API Key from Etherscan and set it as an environemnt variable named ETHERSCAN_API_KEY
. You can pop it into your .env
file as seen in the .env.example
.
In it's current state, if you have your api key set, it will auto verify sepolia contracts!
However, you can manual verify with:
yarn hardhat verify --constructor-args arguments DEPLOYED_CONTRACT_ADDRESS
