chore(revm): defer bytecode load #1588

Closed lightsing closed 2 months ago

lightsing commented 3 months ago

Current revm try to load bytecode just after depth check, but there are some conditions the code is not needed:

insufficient balance to transfer
call to a precompile address

As long as the code is not needed, the database provider may not have corresponding code, like in our implementation scroll-tech/stateless-block-verifier#15 use this as an optimization.

Looks reasonable, will check it again to be sure
