A detailed comparison of the time, cost, and risk involved in building a custom KYC solution versus using Chainscore's managed service for NFT marketplaces.
| Key Factor | Build In-House | Chainscore Managed Service |
|---|---|---|
Time to Launch | 6-12 months | 2-4 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Ongoing Compliance & Updates | Your team's responsibility | Fully managed by Chainscore |
Regulatory Coverage | Limited to initial research | Global (FATF, AML5, MiCA, etc.) |
Identity Verification Methods | Requires multiple vendor integrations | Unified API (Document, Liveness, Database) |
Smart Contract Security Risk | High (requires independent audit) | Low (pre-audited, upgradeable modules) |
Uptime & Support SLA | None (internal team dependent) | 99.9% with 24/7 monitoring |
Scalability to New Jurisdictions | High complexity & cost per region | Included in service |
Total Cost of Ownership (Year 1) | $200K - $500K+ | $50K - $150K |
A modular, API-first approach that embeds identity verification directly into your NFT marketplace user flows, ensuring regulatory compliance without sacrificing user experience.

Get clear, technical answers to the most common questions about integrating identity verification for your NFT marketplace.
A standard NFT marketplace KYC integration takes 2-4 weeks from kickoff to production deployment. This includes requirements analysis, smart contract development, frontend widget integration, and a full security audit. For marketplaces with complex token-gating or multi-chain requirements, timelines may extend to 6-8 weeks.
