- Integration Support: Seamless connection to frontends, oracles, and cross-chain bridges.
Security for ZK-Rollup Oracle Data Feeds
Build vs. Buy: In-House Review vs. Specialized Audit
A direct comparison of the costs, risks, and outcomes between developing an internal security review process and engaging a specialized audit firm like Chainscore Labs.
| Security Factor | Build In-House | Buy: Chainscore Audit |
|---|---|---|
Time to Initial Security Review | 3-6 months (team ramp-up) | 2-4 weeks (immediate start) |
Expertise in ZK-Circuits & Rollups | Requires hiring/training | Pre-vetted team with 50+ ZK audits |
Audit Depth (CVE Discovery Rate) | Low-Medium (limited tooling) | High (proprietary fuzzing + formal verification) |
Cost (One-Time Audit) | $80K-$200K+ (internal labor) | $25K-$75K (fixed scope) |
Ongoing Security Monitoring | Your team's responsibility | Optional SLA with 24/7 threat detection |
Auditor Credibility for Fundraising | Minimal (self-attested) | High (verified report from top-5 firm) |
Remediation Support | Internal debugging | Direct engineer access for fixes |
Risk of Critical Vulnerability Post-Launch | High | Negligible (insured coverage available) |
Total Cost of Ownership (Year 1) | $250K+ | $50K-$150K |
Expert Answers for Technical Decision-Makers
ZK-Rollup Oracle Security FAQ
Addressing the critical questions CTOs and engineering leads ask when securing data feeds for their ZK-rollup applications.
We employ a defense-in-depth strategy. Our process begins with a formal threat model specific to your rollup's architecture and data requirements. We then implement multi-source data aggregation with cryptographic attestation, secure off-chain computation for data processing, and rigorous on-chain verification via zk-SNARKs or zk-STARKs. All custom oracle adapters are built using audited libraries and follow a secure development lifecycle with mandatory peer review.
