Strategic Comparison
Managed Service vs. In-House Migration
A detailed breakdown of the cost, risk, and resource trade-offs between building a mobile wallet migration solution internally versus leveraging Chainscore's managed service.
| Key Factor | In-House Development | Chainscore Managed Service |
|---|---|---|
Time to Market | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $75K - $200K |
Security & Audit Burden | High (Your team's responsibility) | Low (Included with SOC 2 & audit reports) |
Ongoing Maintenance & Updates | Dedicated 2-3 engineers | Fully managed with 99.9% SLA |
Protocol & Chain Support | Requires continuous R&D | Pre-integrated (EVM, Solana, etc.) |
Key Management & Custody Risk | Your liability | Mitigated via MPC/TSS architecture |
Scalability & Performance | Requires load testing & optimization | Built for 10,000+ TPS, auto-scaling |
Total Cost of Ownership (Year 1) | $500K - $1.2M+ | $150K - $400K |

Enterprise Wallet Migration FAQs
Get clear answers on timelines, security, and process for migrating your existing wallet infrastructure to a modern, secure mobile platform.
Our standard enterprise wallet migration is completed in 4-6 weeks. This includes a 1-week discovery & planning phase, 2-3 weeks for core development and security hardening, and 1-2 weeks for rigorous testing, deployment, and client onboarding. Complex integrations (e.g., custom MPC, multi-chain DeFi) may extend this to 8-10 weeks. We provide a detailed project plan with milestones during the initial scoping call.
