PROVEN PROCESS
Our ZK-Rollup Security Audit Methodology
Our systematic, multi-layered approach is designed to identify critical vulnerabilities in your ZK-Rollup stack, from the core circuits to the bridge and sequencer logic, ensuring your protocol is secure before mainnet launch.
01
Architecture & Specification Review
We begin with a deep-dive analysis of your ZK-Rollup's technical design, state transition logic, and data availability model to identify systemic risks and architectural flaws before line-by-line review.

Expert Answers for Technical Decision-Makers
ZK-Rollup Security Audit FAQs
Get clear, specific answers to the most common questions CTOs and engineering leads ask when evaluating a ZK-Rollup security audit partner.
We employ a comprehensive, multi-layered methodology based on industry standards like OWASP and NIST. Our audit covers the full ZK-Rollup stack:
- Core Circuit Logic: Formal verification of ZK-SNARK/STARK circuits for soundness and completeness.
- Smart Contracts: In-depth review of on-chain verifiers, bridges, and governance contracts using static/dynamic analysis.
- Node Software: Penetration testing of the sequencer, prover, and relayer components for RPC-level exploits.
- Cryptographic Primitives: Validation of elliptic curve implementations, signature schemes, and trusted setup assumptions.
Every engagement includes a threat modeling session and culminates in a detailed report with severity ratings (Critical/High/Medium/Low), PoC exploits, and actionable remediation guidance.
