Getting Started
Requirements
- 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 output like:vx.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 like:x.x.x
- You might need to install it with
npm
orcorepack
- You'll know you've installed yarn right if you can run:
Quickstart
git clone https://github.com/Lisanaaa/Revenue-Based-Defi.git
cd Revenue-Based-Defi
yarn
yarn hardhat
Usage
Deploy:
npx hardhat run scripts/deploy.js
Testing
npx hardhat test
Test Coverage
npx hardhat coverage
Estimate gas
You can estimate how much gas things cost by running:
npx hardhat test
And you'll see and output file called gas-report.txt
Local Deployment
If you'd like to run your own local hardhat network, you can run:
npx hardhat node
And then in a different terminal
npx hardhat run scripts/deploy.js --network localhost
And you should see transactions happen in your terminal that is running npx hardhat node
Important localhost note
If you use metamask with a local network, everytime you shut down your node, you'll need to reset your account. Settings -> Advanced -> Reset account. Don't do this with a metamask you have real funds in. And maybe don't do this if you're a little confused by this.
Deployment to a testnet or mainnet
- Setup environment variables
You'll want to set your RINKEBY_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.
RINKEBY_RPC_URL
: This is url of the rinkeby 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
npx hardhat run scripts/deploy.js --network rinkeby
Verify on etherscan
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 environment 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 rinkeby contracts!
However, you can manual verify with:
npx hardhat verify --constructor-args arguments.js DEPLOYED_CONTRACT_ADDRESS
Linting
To check linting / code formatting:
yarn lint
or, to fix:
yarn lint:fix
