feat: detect evm version when forking from a certain height #9

Closed banteg closed 2 years ago

banteg commented 2 years ago

What I did

allow specifying evm_version in fork config
automatically choose the correct fork if a block number is specified

How I did it

add ecosystem:network:start_block:evm_version mapping
hardcode block to fork mapping for ethereum mainnet
guess version from upsteam provider if block is provided but evm version is not provided, providing less surprising behavior when forking from older blocks
add a --hardfork argument to anvil if we run something other than the latest fork

How to verify it

fork from an old block
