Fraud Proof Integration & Upgrade Consulting
Build In-House vs. Partner with Chainscore
A detailed comparison of the resource investment, risk, and timeline for developing fraud proof systems internally versus leveraging Chainscore's specialized consulting.
| Key Factor | Build In-House Team | Partner with Chainscore |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Upfront Development Cost | $250K - $600K+ | $75K - $200K |
Security & Audit Risk | High (Custom, unaudited code) | Low (Pre-audited patterns, formal verification) |
Core Expertise Required | ZK/OP Circuits, Solidity, Node.js, DevOps | Your existing team + our specialists |
Ongoing Maintenance Burden | Full-time team (2-3 engineers) | Optional SLA with 24/7 monitoring |
Protocol Upgrade Support | Manual research & implementation | Guided upgrades with change impact analysis |
Guaranteed Uptime SLA | Self-managed (typically < 99.5%) | 99.9% with defined penalties |

Our Phased, Risk-Managed Delivery Process
We de-risk your fraud proof integration through a structured, milestone-driven approach. Each phase delivers verified value before proceeding, ensuring your production environment remains secure and stable.
01
Phase 1: Architecture & Threat Modeling
We conduct a comprehensive audit of your existing rollup architecture to identify fraud proof integration points and potential attack vectors. Deliverables include a detailed threat model and a phased implementation roadmap.

Technical & Commercial Questions
Fraud Proof Integration FAQs
Get clear answers on timelines, costs, and technical requirements for integrating fraud proofs into your L2 or optimistic rollup.
A standard integration for a custom L2 or existing optimistic rollup takes 4-8 weeks, from initial architecture review to mainnet deployment. This includes design, implementation, testing, and security audit integration. For protocol upgrades (e.g., migrating to a new fraud proof system), timelines are typically 2-4 weeks. We provide a detailed project plan in the first week.
