The Strategic Choice for Your Wallet Infrastructure
Build vs. Buy vs. Our Modular Framework
Compare the total cost of ownership, risk, and time-to-market for three approaches to multi-chain wallet integration.
| Key Factor | Build In-House | Generic Third-Party SDK | Chainscore Modular Framework |
|---|---|---|---|
Time to First Integration | 4-6 months | 2-4 weeks | 1-2 weeks |
Supported Chains (Initial) | 1-2 chains | 5-10 chains | 15+ chains (EVM & non-EVM) |
Security & Audit Responsibility | Your team (High risk) | Vendor (Mixed risk) | Chainscore (Audited, low risk) |
Custom Feature Development | Full control, high cost | Limited or impossible | Modular, plug-and-play |
Ongoing Chain Updates | Your team's burden | Vendor schedule (slow) | Automatic, same-day support |
Multi-Chain Gas Abstraction | Build from scratch | Often unavailable | Built-in, production-ready |
Team Expertise Required | Senior blockchain engineers | General mobile/web devs | Standard mobile/web devs |
First-Year Total Cost | $250K - $500K+ | $50K - $100K + usage fees | $75K - $150K flat (SLA included) |
Scalability to New Chains | Months of development | Months of waiting | Days, via modular adapters |
Dedicated Technical Support | N/A (Your team only) | Community or ticket-based | Priority Slack & engineering access |
