THE CHAINSCORE DIFFERENCE
Why Choose a Specialized ZK Audit
Zero-Knowledge cryptography introduces unique, complex vulnerabilities that generic smart contract audits miss. Our dedicated ZK practice delivers the deep protocol expertise required to secure your privacy-preserving applications.
01
Protocol-Specific Expertise
Our auditors are certified in zk-SNARKs (Groth16, Plonk), zk-STARKs, and Bulletproofs. We audit the full stack: from circuit logic (Circom, Noir) to verifier contracts, ensuring mathematical soundness and implementation correctness.

02
Cryptographic Rigor
We go beyond Solidity to scrutinize the underlying math. Our review includes trusted setup assumptions, constraint system validity, and soundness/zero-knowledge proofs to prevent critical logic flaws and privacy leaks.

Gas & Performance Optimization
ZK verifier contracts are notoriously expensive. We optimize constraint counts, proof generation time, and on-chain verification gas costs without compromising security, directly reducing your mainnet operational expenses.

Adversarial Testing & Fuzzing
We employ custom fuzzing harnesses and adversarial test vectors specifically for ZK circuits. This uncovers edge cases in input validation, elliptic curve operations, and proof verification that static analysis misses.
