COMPREHENSIVE SECURITY REVIEW
What Our ZK-Rollup Bridge Audit Covers
Our audit delivers a rigorous, line-by-line security assessment of your bridge's core components, providing the actionable insights needed to protect user funds and ensure protocol integrity before mainnet launch.
01
Smart Contract Security
In-depth review of bridge, escrow, and governance contracts for vulnerabilities like reentrancy, logic flaws, and access control issues. We provide remediation guidance for all findings.

SECURITY DIFFERENTIATORS
Why a Specialized ZK-Rollup Audit is Critical
Generic audits miss the complex, protocol-specific vulnerabilities inherent to ZK-rollup bridge interfaces. Our specialized audit methodology delivers the depth and precision required to secure your cross-chain value transfers.
01
Zero-Knowledge Circuit Logic Review
We audit the mathematical soundness of your ZK-SNARK/STARK circuits and prover/verifier logic to prevent critical failures in proof generation or validation.

Frequently Asked Questions
Get clear answers on our security audit process, timeline, and deliverables for your ZK-Rollup bridge interface.
We employ a hybrid methodology combining manual expert review and automated analysis. Our process includes: 1) Architecture review of the bridge's state transition and fraud/validity proof system, 2) Line-by-line code review of core contracts (deposit, withdrawal, verification), 3) Fuzzing and invariant testing for edge cases, and 4) Economic and incentive analysis of the security model. We benchmark against known vulnerabilities in major rollups like zkSync, StarkNet, and Polygon zkEVM.
