Testnet deployment

brownie networks list

displays list of networks:

these are temporary, like ganache networks.
networks are torn down after running
contracts and transactions sent on these networks are deleted after our script completes

With remix we used MetaMask to connect to a proper testnet. In brownie, there is no such injection connection.

To connect to a blockchain node, we will use the RPC URL provided by infura or alchemy.

create a project in Infura
go to project settings, and look for project ID:
in .env add the following line:
- export WEB3_INFURA_PROJECT_ID = cd3a18407dfe4d2597f756dafe2804d6

brownie run scripts/deploy.py --network rinkeby

We can look up the transaction hashes and the contract address on rinkeby etherscan.
