To be honest I was kind of surprised I didn't found it in mathlib. Perhaps that is not _idiomatic_ Lean solution?

I think this predicate should also compare evm states in the case where the second state is a Checkpoint no? 🙂

This is just a projection function, it's not a monotonicity statement. It says that you can take out the last component of and.
The thing that you will need at some point is stuff like: insert is monotonic in its second argument given the preorder on your maps, i.e.:
m1 <= m2 -> insert x m1 <= insert x m2.
