The Strategic Decision
Build vs. Buy: On-Chain Screening Integration
A detailed comparison of the time, cost, and risk involved in developing sanctions screening infrastructure in-house versus leveraging Chainscore's proven, audited solution.
| Factor | Build In-House | Chainscore Integration |
|---|---|---|
Time to Production | 6-12 months | 2-4 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Security & Audit Overhead | High (unaudited risk) | Low (pre-audited, battle-tested) |
Ongoing Maintenance | 2-3 FTE engineers | Fully managed service |
Coverage (Blockchains) | Limited to team expertise | EVM, Solana, Cosmos, 20+ chains |
Regulatory List Updates | Manual, lagging | Automated, real-time (<5 min) |
False Positive Rate | 15-30% (typical) | <5% (ML-optimized) |
Total Cost of Ownership (Year 1) | $300K - $700K | $50K - $150K |
