THE DIFFERENCE
Why a Specialized ZK Audit is Critical
Generic smart contract audits miss the unique complexities of zero-knowledge systems. Our specialized review targets the mathematical soundness and cryptographic assumptions that underpin your rollup's security and performance.
01
Circuit Logic & Soundness
We verify the mathematical correctness of your ZK circuits, ensuring they accurately encode your business logic and produce valid proofs for all correct inputs and none for incorrect ones.
100%
Logic Coverage
02
Cryptographic Assumptions
We audit the underlying cryptographic primitives (e.g., elliptic curves, hash functions) and their implementation for vulnerabilities, side-channel attacks, and adherence to established security standards.

Assumption Gaps
03
Verifier Contract Security
In-depth review of the on-chain verifier smart contract, focusing on gas optimization, reentrancy risks, and correct proof verification to prevent fraudulent state transitions.
< 200k

ZK-Rollup Security Review FAQs
Get specific answers on our methodology, timeline, and deliverables for securing your ZK-Rollup's core logic.
We follow a structured, three-phase approach: 1) Architecture & Specification Review to assess design against ZK-Rollup best practices. 2) Circuit & Verifier Code Audit using static analysis, manual review, and formal verification tools to find logic flaws, soundness errors, and gas inefficiencies. 3) Integration & Adversarial Testing to verify on-chain verifier deployment and simulate attack vectors. We benchmark against standards from Ethereum Foundation research and major L2 teams.
