Move Prover is practical for critical modules; verify resource safety, invariants, access control, and side effects before shipping.

Move Prover is practical for production-grade modules when applied selectively to critical components, such as token logic, staking mechanisms, or shared-object state transitions. It excels at formally verifying resource safety, access control, and invariant preservation, ensuring assets aren’t duplicated or lost and only authorized actors can perform sensitive actions. While it may be overkill to prove every utility function, focusing on core financial logic, state migration paths, and shared-object invariants provides high assurance without excessive overhead. In practice, Move Prover is typically combined with unit tests, integration tests, and code audits, offering a strong layer of formal security while keeping development efficient.

You can use the Move Prover in production to mathematically check that your smart contract logic behaves exactly as intended, and it’s especially practical for modules handling critical assets like stablecoins, DeFi protocols, or governance tokens because it lets you prove safety properties such as no double spends, correct access control, or conservation of balances. While the tool is still evolving, it already integrates well with the Move language, so you can embed specifications directly in your code and run proofs as part of development or CI pipelines. The main trade-off is that writing strong specifications takes extra effort and expertise, but once in place, it reduces reliance on traditional audits alone and gives you much higher confidence in correctness. This makes Move Prover a realistic option for production-grade modules where security outweighs convenience. Read more: https://docs.sui.io/learn/verify/move-prover
