Is there any sort of memory safety prover for zig? Similar to SPARK for Ada

No - but there are interesting proofs-of-concept and linters and strategies that I’m fairly convinced will lead there in time.

why not valgrind?  
or it’s not enough?

Valgrind can detect memory safety violations in a particular run of software (for particular inputs). SPARKAda can prove that _no_ run can violate memory safety, irrespective of inputs. The difference is ∀ quantifier.
