An example smart contract toolkit

pip install --user pipx

pipx ensurepath

# restart your terminal
pipx install eth-brownie

Add Folkafoundry halongbay network

brownie networks add Polkafoundry halongbay host=https://rpc-halongbay.polkafoundry.com chainid=11

You'll need the following environment variables. You can set them all in your .env file:

export WEB3_INFURA_PROJECT_ID=YourProjectID
export ETHERSCAN_TOKEN=''
export PRIVATE_KEY="0xasdfasdfasdfasd..."
export MNEMONIC=''

• WEB3_INFURA_PROJECT_ID: Your connection to the blockchain. You can get a URL from a service like Infura
• ETHERSCAN_TOKEN:
• PRIVATE_KEY: Your Private Key from your Wallet. If using metamask, you'll have to add a 0x to the start of your private key.
• MNEMONIC: Your menemonic phase

This doesn't auto-pull in your .env file at the start, so you have to set your environment variables at the start.

source .env

brownie run scripts/deploy.py
brownie run scripts/deploy.py --network kovan
brownie run scripts/deploy.py --network halongbay

To run the tests:

brownie test
brownie test --network kovan
brownie test --network halongbay
