Brownie Networks

Networks created

brownie networks list true

will return full details of each network

Under Ethereum category

• ganache-local is our persistent mock network

• requires that ganacheUI is running, so that brownie will latch onto it automatically to deploy required mock contracts.

• Persistency will last till ganacheUI is closed.

Forking and MockingMocking

Development:

mainnet-fork-dev

• Forks ETH mainnet

• Provider: Alchemy

-- brownie networks add development mainnet-fork-dev cmd=ganache-cli host=http://127.0.0.1 fork=https://eth-mainnet.alchemyapi.io/v2/j13raIIaPyTnV9ZVv2UnQm48PUFcPDkL accounts=10 mnemonic=brownie port=8545

mainnet-fork

• brownie comes preset with mainnet-fork under Development category:

• connects to infura, and requires infura token in .env.

• Infura causes problems, so Patrick overwrites it to use Alchemy

• we shall do this too

brownie networks add development mainnet-fork cmd=ganache-cli host=http://127.0.0.1 fork=https://eth-mainnet.alchemyapi.io/v2/QQSu6nAAnOvWlkS9KTHk9UGk-kxieDmj accounts=10 mnemonic=brownie port=8545

On Ganache UI and CLI

perhaps changing ganacheUI port number to be something else, could prevent brownie(ganache-cli) to auto-attach itself, if ui is running.

This way we can control networks with port numbers.
