Why Synthetic State is Essential for Move
Synthetic State Testing vs. Traditional Methods
A direct comparison of testing methodologies for Move smart contracts, highlighting the critical advantages of synthetic state generation for security and reliability.
| Testing Factor | Traditional Unit/Integration Testing | Chainscore Synthetic State Testing |
|---|---|---|
State Coverage | Limited to developer-defined scenarios | Exhaustive, automated generation of complex states |
Edge Case Discovery | Manual, relies on developer foresight | Automated discovery of hidden invariants and edge cases |
Time to Comprehensive Test Suite | Weeks to months of manual work | Generated in hours from the contract source |
Pre-Production Bug Detection | Low to Moderate | High (catches state-specific logic errors) |
Cost of Missed Bugs | High (post-deployment exploits) | Minimal (pre-deployment remediation) |
Integration with CI/CD | Manual script management | Fully automated pipeline integration |
Audit Readiness | Requires significant prep work | Delivers audit-ready test reports and coverage metrics |
Team Resource Requirement | 2-3 Senior Move Engineers | Managed service with expert oversight |

Frequently Asked Questions
Get clear answers about our synthetic state testing methodology, process, and outcomes for Move-based applications.
Synthetic state testing is a specialized methodology where we programmatically generate and simulate complex, realistic blockchain states to test your Move contracts under conditions that mimic mainnet. Unlike basic unit tests, we create adversarial scenarios, simulate multi-user interactions, and stress-test edge cases like flash loan attacks or oracle manipulation specific to Aptos and Sui's state models. This uncovers logic flaws, reentrancy risks, and gas optimization issues before deployment.
