Move Prover & Cairo Formal Verification
We apply formal verification tools like the Move Prover (Aptos/Sui) and Cairo's proof system (StarkNet) to mathematically prove the correctness of your critical business logic, such as commission calculations in affiliate platforms.

PROVEN SECURITY
Our Formal Verification Capabilities
We apply mathematical rigor to guarantee the correctness of your Move and Cairo smart contracts, eliminating entire classes of vulnerabilities before deployment.
03
Specification Development
We translate your business requirements and invariants into precise, machine-verifiable specifications. This creates a single source of truth for what your contract must and must not do.
04
Invariant & Property Testing
Beyond basic functions, we verify critical system-wide invariants (e.g., "total supply is constant", "no unauthorized minting") and temporal properties to prevent reentrancy and state corruption.
05
Audit-Ready Code Delivery
We deliver formally verified contracts with comprehensive specification documents. This drastically reduces manual audit time and cost, providing auditors with a proven foundation for their review.
06
Developer Training & Workflow
We train your engineering team on writing verifiable code and integrating formal methods into your CI/CD. We provide templates and tooling to maintain verification standards.

THE FORMAL VERIFICATION ADVANTAGE
Why Mathematically Verified Contracts Win
Move Prover and Cairo formal verification transform contract security from probabilistic to deterministic. We deliver mathematically proven correctness, eliminating entire classes of vulnerabilities before deployment.
01
Zero Critical Bugs at Launch
We deliver contracts with mathematically proven correctness against your formal specifications. This eliminates critical vulnerabilities like reentrancy, overflow, and logic errors that traditional audits can miss.

Choosing the Right Security Methodology
Formal Verification vs. Traditional Audits
A technical comparison of two distinct approaches to securing smart contracts, highlighting the mathematical rigor of formal verification versus the expert-driven nature of traditional audits.
| Security Aspect | Traditional Code Audit | Formal Verification (Move Prover/Cairo) |
|---|---|---|
Methodology | Manual review by security experts | Mathematical proof of correctness |
Coverage | Sample-based; depends on auditor skill | Exhaustive; verifies all possible execution paths |
Guarantee | High confidence, but not absolute | Mathematical proof of specified properties |
Primary Output | Vulnerability report with recommendations | Formal proof or counterexample for each property |
Time to Complete | 2-4 weeks for standard scope | 3-6 weeks (includes property specification) |
Cost Range | $15K - $50K+ (scope-dependent) | $30K - $100K+ (complexity-dependent) |
Best For | General code review, catching common bugs, new protocols | Mission-critical logic, financial primitives, protocol upgrades |
Limitations | Cannot prove absence of all bugs | Limited to formally specified properties; requires expert specification |
Ongoing Value | One-time snapshot; degrades with new code | Proofs remain valid unless specifications or code change |
Recommended Use | All production contracts | Core settlement, bridge, or governance contracts |

RIGOROUS & REPEATABLE
Our Verification Process
Our formal verification methodology is designed to eliminate critical vulnerabilities before deployment, providing mathematical certainty of your smart contract's security and correctness.
01
Specification & Modeling
We translate your business logic and security requirements into a formal specification using the Move Prover or Cairo's Sierra IR. This creates a precise, machine-verifiable model of your intended contract behavior.

Requirement Coverage
1-3 days
Initial Setup
02
Property Definition & Invariant Checking
Our experts define critical security properties and system invariants (e.g., "no unauthorized minting", "total supply conservation"). The prover mathematically verifies these hold under all possible execution paths.

State Coverage
03
Automated Proof Generation
We run the formal verification toolchain to generate mathematical proofs. Any violation of the specification is flagged as a counterexample, pinpointing the exact line and condition that breaks the contract's logic.

04
Remediation & Iteration
We provide developers with actionable, line-by-line remediation guidance for any counterexamples found. The process iterates until the proof passes completely, guaranteeing the code matches the specification.

Formal Verification FAQs
Get clear, technical answers to the most common questions about our formal verification services for Move and Cairo smart contracts.
A standard verification project for a core protocol module takes 2-4 weeks from audit-ready code to final report. This includes specification writing, property definition, proof execution, and remediation support. Complex systems with multiple interdependent contracts may extend to 6-8 weeks. We provide a detailed project plan within 48 hours of the initial technical review.
