1. Install Brownie

python3 -m pip install --user pipx
python3 -m pipx ensurepath
# restart your terminal
pipx install eth-brownie

Or, if that doesn't work, via pip

pip install eth-brownie

2. Clone this

git clone https://github.com/PatrickAlphaC/brownie_simple_storage
cd brownie_simple_storage

3. Add your metamask to the brownie accounts at the 0 index

brownie accounts new 0

You'll be prompted to add your private key: 0xa5555555555555a09215803a6b540f1e054797eeda2eec6d49076760d48e7589 And a password, and you can see your new added account with brownie accounts list

Or, export your PRIVATE_KEY as an environment variable, and uncomment the line:

# account = accounts.add(config["wallets"]["from_key"])

and comment the line:

account = accounts[0]

4. Testing

brownie run test

5. Running scripts

brownie run scripts/deploy.py

6. Deploy to a testnet

Add your WEB3_INFURA_PROJECT_ID from Infura to your .env and run

source .env

To set your environment variable. You can check you've done it correctly with:

echo $WEB3_INFURA_PROJECT_ID

Change the deploy_simple_storage function in deploy.py to look like:

account = accounts.add(config["wallets"]["from_key"])
# account = accounts.load("id")
# account = accounts[0]

Then run:

brownie run scripts/deploy.py --network rinkeby

Make sure you have some testnet ETH. You can find faucets in the Chainlink Documenatation
