Forwarder: Create a smart contracts that can accept funds as if they
were ordinary accounts, with the sole functionality of forwarding the
accepted funds to a fixed, predetermined address.
Factory: factory pattern significantly helps reduce the cost of these
transactions. Instead of encoding the same logic multiple times when deploying
a new Forwarder, we can deploy a single ForwarderFactory that knows how to
instantiate new Forwarders.
Create2: Predict what a smart contract address will be without deploying
the smart contract.
