PROVEN FRAMEWORK
Our ZK-Focused Audit Methodology
Our systematic approach is engineered for the unique complexities of zero-knowledge circuits and confidential smart contracts, delivering actionable security insights.
01
Circuit Logic & Constraint Analysis
Deep review of zk-SNARK/STARK circuit logic, constraint systems, and arithmetic gates for soundness and correctness. We identify vulnerabilities like under-constrained circuits and incorrect zero-knowledge proofs.

Constraint Coverage
Circom, Noir, Halo2
Supported Frameworks
02
Confidential State & Data Flow
Specialized audit of private state transitions, encrypted mempools, and data flow within confidential smart contracts (e.g., Aztec, Aleo). Ensures data privacy is maintained without compromising integrity.

Leakage Detection
FHE, TEEs
Privacy Models
03
Cryptographic Primitive Verification
Examination of elliptic curve implementations, pairing functions, hash functions, and signature schemes used in proof systems. Validates compliance with cryptographic best practices to prevent forgery and collision attacks.

Your Security Questions, Answered
Confidential Contract Audit FAQs
Get clear answers about our confidential smart contract audit process, timeline, and security guarantees.
We follow a rigorous, multi-layered methodology. It begins with a manual code review by senior auditors to understand business logic and architecture. This is followed by automated analysis using tools like Slither and Mythril to identify common vulnerabilities. The core is a targeted manual testing phase, where we simulate attacks, review access controls, and validate financial math. Every finding is documented with a severity rating (Critical, High, Medium, Low), a clear explanation, and a specific code fix. The process concludes with a remediation review and a final report.
