Key Takeaways for Security Teams
- Combines symbolic execution with SMT solvers to eliminate edge-case exploits.
Formal verification uses mathematical proofs to verify that smart contracts adhere strictly to their formal specifications in all possible state execution paths.
Mathematical Invariant Proofs with Z3
While fuzzing tests thousands of random inputs, formal verification checks infinite potential state transitions to prove mathematically that solvency invariants can never be broken.
