PROVEN METHODOLOGY
Our Formal Verification Capabilities
We apply rigorous mathematical proofs to verify the correctness of your rollup's core logic, eliminating entire classes of bugs before deployment. This is your strongest defense against catastrophic failures and financial loss.
01
Smart Contract & Circuit Verification
Formal verification of your rollup's smart contracts (Solidity/Vyper) and zero-knowledge circuits (Cairo, Noir, Circom) using tools like K, Certora, and Halmos. We prove invariants and security properties, not just test them.

02
State Transition Proofs
Mathematical verification of your state transition function—the heart of your rollup. We prove that state updates are deterministic, correct, and adhere to the protocol rules under all possible conditions.

Bridge & Fraud Proof Security
Formal analysis of your cross-chain bridge contracts and fraud proof/validity proof mechanisms. We verify the security of fund locking, message passing, and challenge protocols to prevent bridge hacks.

Economic & Incentive Modeling
Verification of your rollup's cryptoeconomic safety. We model sequencer/validator incentives, slashing conditions, and fee mechanisms using tools like CadCAD to ensure system stability and honest behavior.

05
Specification & Compliance Proofs
We create a formal, machine-readable specification of your protocol (in TLA+, Coq, or similar) and prove your implementation matches it. Essential for regulatory compliance and institutional adoption.

THE BUSINESS CASE FOR CERTAINTY
Why Founders and CTOs Choose Formal Verification
For CTOs managing multi-million dollar TVL and founders protecting their protocol's reputation, formal verification is a strategic investment in risk mitigation and investor confidence. It moves security from a reactive cost to a proactive asset.
01
Eliminate Critical Vulnerabilities Pre-Launch
Our formal methods mathematically prove your rollup's core logic (sequencer, prover, bridge) is free from entire classes of bugs, preventing catastrophic failures that traditional testing and audits can miss.

A Security Paradigm Comparison
Formal Verification vs. Traditional Security Methods
Understanding the fundamental differences between exhaustive mathematical proof and probabilistic testing for securing rollup smart contracts.
| Security Dimension | Traditional Audits & Testing | Chainscore Formal Verification |
|---|---|---|
Verification Method | Manual review, unit/integration tests, fuzzing | Mathematical proof of correctness |
Coverage Guarantee | Probabilistic (sample-based) | Exhaustive (100% of state space) |
Critical Bug Detection | High likelihood, not guaranteed | Guaranteed for specified properties |
Time to Security Proof | 2-4 weeks for audit report | 4-8 weeks for machine-checked proof |
Ongoing Assurance | Requires re-audit after changes | Proofs re-verified automatically on each commit |
Cost Structure | $15K - $100K+ per audit cycle | $50K - $200K+ for initial proof; lower maintenance cost |
Ideal For | Early-stage MVPs, non-critical logic | Core settlement, bridge, and sequencer contracts |
Output | PDF report with findings and recommendations | Machine-verifiable proof artifact and CI/CD integration |

Technical & Process Questions
Formal Verification FAQs
Get clear answers on how our formal verification service works, from methodology and timeline to security guarantees and ongoing support.
We employ a rigorous, multi-stage methodology: 1) Specification Formalization: We work with your team to translate business logic and security requirements into precise mathematical properties. 2) Model Building: We create a formal model of your rollup's state machine and smart contracts using tools like K-Framework or Coq. 3) Property Verification: We use automated theorem provers (e.g., Dafny, Certora Prover) and model checkers to mathematically prove the system adheres to its specifications. 4) Report & Remediation: We deliver a comprehensive report with proofs and any discovered issues, collaborating on fixes until all properties are formally verified.
