Managed Service vs. In-House Execution
Compare the cost, risk, and resource allocation of managing a major network upgrade or migration internally versus with Chainscore's expert service.
| Key Factor | In-House Execution | Chainscore Managed Service |
|---|---|---|
Time to Market | 4-8 months | 4-8 weeks |
Upfront Team Cost | $150K-$300K+ | $50K-$150K |
Security & Audit Overhead | High (manual, unaudited process) | Low (pre-audited migration frameworks) |
Protocol-Specific Expertise | Requires hiring/ramp-up | Included (EIP-1559, EIP-4844, etc.) |
Post-Upgrade Monitoring | Your team's responsibility | Included for 30-90 days |
Risk of Downtime / Fork Issues | High (single point of failure) | Mitigated (redundant coordination) |
Total Cost of Ownership (Year 1) | $300K-$600K+ | $75K-$200K |

STRUCTURED FOR ZERO DOWNTIME
Our Four-Phase Migration Methodology
A proven, battle-tested framework for executing complex blockchain migrations with minimal risk and zero service disruption for your users.
01
Phase 1: Strategic Assessment & Planning
We conduct a comprehensive audit of your existing architecture, smart contracts, and dependencies. This phase delivers a detailed migration blueprint, risk matrix, and a rollback plan, ensuring every technical and business requirement is mapped before a single line of code is changed.
48-72 hours
Initial Audit

Phase 2: Development & Pre-Production Testing
Our engineers build and deploy the migration contracts and tooling in an isolated staging environment. We execute exhaustive testing, including state migration simulations, edge-case handling, and security audits against the new network specifications.

Phase 3: Staged Production Deployment
We orchestrate a phased, canary-style rollout. This begins with migrating non-critical components and a subset of users, monitoring performance and stability in real-time. Our automated tooling ensures data consistency and atomic transaction execution across the old and new networks.
