Secure Move Contract Deployment
What are the key security checks before deploying a Move module?

Answers
3Ensure resource safety, invariant preservation, proper access control, and test edge cases; optionally use Move Prover for formal verification.
Before deploying a Move module, check for:
• Resource safety: No duplication or leakage
• Access control: Proper permissions and validations
• Formal verification: Use Move Prover for critical logic
• No unintended aborts: Handle errors gracefully
• Test coverage: Unit/integration tests for all paths
• Review dependencies: Avoid insecure or outdated code
These steps help ensure secure, reliable deployment.
Before you deploy a Move module, you need to make sure it’s free of design flaws and implementation bugs that could compromise assets or logic. First, verify ownership and access control — only the right actors should be able to call privileged functions, often handled with capabilities instead of global checks. Next, check for proper object ownership and transfer rules to prevent unintended duplication or loss of assets. Then, validate invariants with the Move Prover or other formal methods, ensuring critical properties like “tokens can’t be created out of thin air” always hold. Also review resource management — Move enforces no implicit copy or drop, but you still need to confirm resources are consumed or transferred safely. Finally, perform thorough testing in local and testnet environments, simulate edge cases, and have an external audit if possible. Following these steps ensures your deployment is resilient against misuse and bugs.
