BEYOND STANDARD SECURITY
Why a Specialized ZK Bridge Audit is Critical
Generic smart contract audits miss the unique cryptographic and cross-chain complexities of zero-knowledge bridges. Our targeted assessment identifies the high-impact vulnerabilities that threaten asset integrity and protocol solvency.
01
Cryptographic Circuit Verification
We audit the core ZK-SNARK/STARK circuits and trusted setups for soundness flaws, ensuring your proof system cannot be fooled to mint invalid assets or approve fraudulent withdrawals.

Cross-Rollup State Synchronization
Our review validates the liveness assumptions, message relay mechanisms, and fraud-proof windows specific to your rollup stack (OP Stack, Arbitrum Nitro, zkSync Era), preventing double-spends and chain reorganizations.

ZK Bridge Security Assessment FAQs
Common questions from CTOs and engineering leads about our comprehensive security assessment process for cross-rollup ZK bridges.
We employ a hybrid methodology combining manual expert review with automated analysis. Our process includes: 1) Architecture & Design Review of the bridge's state model, message passing, and fraud proofs. 2) Smart Contract Audit of on-chain verifiers, relayers, and governance. 3) Cryptographic Review of ZK circuits (Circom, Halo2, etc.), trusted setups, and signature schemes. 4) Economic & Game Theory Analysis of validator incentives and slashing conditions. 5) Operational Security Review of key management and upgrade processes. This multi-layered approach is based on our experience securing over $500M+ in bridged assets.
