This refers to the implementation detail that the coinbase is touched after the transaction execution (see some lines below). This gives 2 coinbase account lookups, but it looks we cannot do better because we are not allowed to create the account here for pre Spurious Dragon revisions.

because we are not allowed to create the account here for pre Spurious Dragon revisions.
Since the condition is >=Shanghai, this can never happen. Or the point of the comment is to explain the condition?
We don't have unit tests for State/Host 😬. We mostly relay on state tests. |
