ZK-KYC Privacy Audit

We audit the core ZK circuits (Circom, Halo2, etc.) for soundness, completeness, and privacy guarantees, ensuring proofs reveal nothing beyond the required attestation.

Security review of smart contracts that verify ZK proofs, checking for gas optimization, reentrancy risks, and correct integration with your protocol's logic.

We identify potential side-channel attacks and data leakage vectors in the full stack—from frontend inputs to blockchain events—to protect user PII.

Assessment of the security and data flow between your application, KYC providers (e.g., Synaps, Persona), and the ZK proof generation layer.

Review of trusted setups, elliptic curve choices, hash functions, and other cryptographic primitives for adherence to current best practices and standards.

Receive a prioritized list of vulnerabilities with severity ratings (Critical/High/Medium) and direct support from our engineers to implement fixes.

We validate the soundness and completeness of your ZK circuits (Circom, Halo2, Noir) to prevent false attestations and ensure proofs cannot be forged, a critical failure point generic audits miss.

Our audit maps proof statements to jurisdictional KYC/AML rules (FATF Travel Rule, MiCA), identifying logic flaws that could leak private user data or create non-compliant attestations.

We test the secure integration of off-chain KYC providers, credential issuers, and on-chain verifiers to prevent oracle manipulation and ensure end-to-end system integrity.

We evaluate your system's upgradeability, credential revocation mechanisms, and interoperability standards (W3C VC, EIP-712) to ensure long-term viability and compliance.
