PROVEN FRAMEWORK
Our Formal Verification Methodology
We apply a rigorous, multi-stage formal verification process to mathematically prove the correctness of your bridge's core logic, eliminating entire classes of vulnerabilities that traditional audits can miss.
01
Specification & Property Definition
We collaborate with your team to formally define the intended behavior and critical security properties of your bridge. This creates an unambiguous mathematical specification against which the code is proven.

Choosing the Right Security Methodology
Formal Verification vs. Traditional Security Audits
A detailed comparison of two critical approaches to securing your mobile bridge smart contracts. Understand the trade-offs in depth, rigor, and cost to make an informed decision for your project's security posture.
| Security Aspect | Traditional Security Audit | Formal Verification |
|---|---|---|
Methodology | Manual code review, heuristic analysis, automated scanning | Mathematical proof of correctness against a formal specification |
Guarantee | Probabilistic: finds many bugs, but cannot prove absence of all | Deterministic: mathematically proves the absence of entire classes of critical bugs |
Coverage Depth | Limited by time, budget, and auditor expertise | Exhaustive for specified properties; explores all possible execution paths |
Ideal For | General code quality, gas optimization, common vulnerability patterns | Core financial logic, bridge security invariants, state transition correctness |
Time to Complete | 2-4 weeks (typical) | 4-8 weeks (comprehensive) |
Cost Range | $15K - $50K (one-time) | $50K - $200K+ (project-dependent) |
Key Output | Vulnerability report with severity ratings and recommendations | Mathematical proof certificate and a verified specification document |
Ongoing Value | Snapshot of code at audit time; requires re-audit for changes | Specification becomes living documentation; proofs can be re-run for updates |
Best Suited For | Standard DeFi protocols, NFT projects, initial security review | Cross-chain bridges, custody solutions, high-value settlement layers |

PREDICTABLE, TRANSPARENT, AND PROVEN
Our Verification Engagement Process
Our structured, four-phase methodology delivers a comprehensive security assessment with clear deliverables and timelines, ensuring your mobile bridge is production-ready.
01
Phase 1: Specification & Scoping
We begin by collaboratively defining the formal specification of your bridge's intended behavior. This includes security invariants, liveness properties, and the precise logic for cross-chain message passing and asset custody.
Deliverable: A complete, machine-readable specification document that serves as the single source of truth for the verification.
02
Phase 2: Model Development & Theorem Proving
Our experts translate your Solidity/Vyper contracts into a formal model using tools like Dafny or Coq. We then mathematically prove that the model adheres to the Phase 1 specifications, eliminating entire classes of logic errors before any testing begins.
Deliverable: A verified formal model and proof report detailing all proven properties.
03
Phase 3: Property-Based Fuzzing & Simulation
We generate and run thousands of adversarial transaction sequences against your actual bytecode using Foundry or Echidna. This tests the real-world implementation against the formal model, uncovering edge cases and gas-related vulnerabilities.
Deliverable: A detailed fuzzing report with discovered issues, test cases, and gas optimization insights.
04
Phase 4: Final Audit & Certification
We consolidate all findings into a final, executive-level audit report. This includes a severity assessment, proof of compliance with the formal spec, and actionable remediation guidance. We provide ongoing support to verify fixes.
Deliverable: A professional audit certificate and report suitable for sharing with partners, investors, and security committees.

Formal Verification for Mobile Bridges: FAQs
Get clear, expert answers to the most common questions about our rigorous formal verification process for cross-chain bridge protocols.
A standard formal verification project for a mobile bridge takes 4-8 weeks, from initial specification to final report. This includes 1-2 weeks for requirement analysis and formal modeling, 3-5 weeks for theorem proving and property verification, and 1 week for report generation and review. Complex bridges with novel consensus mechanisms or intricate state machines may extend this timeline.
