The Infrastructure Decision for Your Identity Layer
Build vs. Buy vs. Our Core
A clear comparison of the time, cost, and risk involved in developing a secure, portable digital identity wallet from scratch, using a generic SDK, or leveraging our production-ready core.
| Key Factor | Build In-House | Buy Generic SDK | Chainscore Core |
|---|---|---|---|
Time to Production | 6-12+ months | 3-6 months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $50K - $150K | $75K - $200K |
Security Audit Burden | Your responsibility (High Risk) | Limited to SDK only (Medium Risk) | Fully audited core + your logic (Low Risk) |
Multi-Chain Portability | Custom integration per chain | Limited to SDK's supported chains | Native support for EVM, Solana, Cosmos, more |
Ongoing Maintenance & Upgrades | Full internal team required | Dependent on vendor roadmap | Managed service with SLA optional |
Compliance Features (KYC/AML) | Custom build, high regulatory risk | Basic hooks, integration required | Pre-built modules, audit-ready |
DeFi & dApp Interoperability | Custom integrations per protocol | Basic wallet connectivity | Pre-integrated with top 50+ DeFi protocols |
Recovery & Key Management | High-risk custom implementation | Standard social recovery | Flexible: MPC, social, custodial options |
Support & Expertise | Internal knowledge only | Community forums, basic tickets | Dedicated technical account manager |
