NewBackend creates a new simulated blockchain that can be used as a backend for contract bindings in unit tests.

WithBlockGasLimit configures the simulated backend to target a specific gas limit when producing blocks.

WithCallGasLimit configures the simulated backend to cap eth_calls to a specific gas limit when running client operations.

WithMinerMinTip configures the simulated backend to require a specific minimum gas tip for a transaction to be included.

Backend is a simulated blockchain.

Client exposes the methods provided by the Ethereum RPC client.
