The Infrastructure Decision for FinTech Leaders
Build vs. Buy vs. Our Modular Plugin
A clear comparison of the three main paths to integrate KYC/AML compliance into your payment SDK, highlighting the total cost of ownership, time-to-market, and risk profile.
| Key Factor | Build In-House | Generic KYC Vendor | Chainscore Modular Plugin |
|---|---|---|---|
Time to Market | 6-12+ months | 8-16 weeks | 2-4 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K | $25K - $75K |
Ongoing Maintenance & Updates | Your team (2+ FTEs) | Vendor roadmap (limited control) | Handled by us (automatic updates) |
Integration Complexity | High (full-stack dev) | Medium (API + custom logic) | Low (drop-in SDK plugin) |
Regulatory Coverage | Your liability (high risk) | Partial (may miss niche rules) | Comprehensive (audited for global standards) |
Smart Contract Security | Unaudited (critical risk) | Not applicable (off-chain only) | Formally audited (OpenZeppelin patterns) |
Multi-Chain Support | Requires rebuild per chain | Often limited to 1-2 chains | Native support for 10+ EVM & non-EVM chains |
Custom Rule Engine | Possible (high effort) | Limited or extra fees | Included (configurable risk profiles) |
Total Cost (Year 1) | $400K - $800K+ | $120K - $250K | $50K - $150K |
Best For | Teams with vast compliance & blockchain dev resources | Non-crypto apps needing basic ID verification | Web3 FinTechs needing compliant, scalable on/off-ramps |
