The Infrastructure Decision for Web3 FinTechs
Build vs. Buy: Chainscore vs. Generic Payment Aggregators
A detailed comparison of the total cost, risk, and time investment between building localized payment rails in-house, using a generic aggregator, or partnering with Chainscore for a purpose-built Web3 solution.
| Key Factor | Build In-House | Generic Aggregator (e.g., Stripe) | Chainscore |
|---|---|---|---|
Time to First Integration | 6-12+ months | 2-4 weeks | 4-8 weeks |
Web3-Specific Coverage | Custom-built | Limited (e.g., USDC only) | Comprehensive (On/Off-ramps, PIX, UPI, SEPA) |
Smart Contract Security | High Risk (Your team's code) | N/A (Custodial) | Low Risk (Audited, battle-tested) |
Settlement to On-Chain Wallets | Your responsibility | Not supported | Native, automated feature |
Regulatory Compliance (KYC/AML) | Your legal team | Their framework (may not fit crypto) | Integrated, crypto-native framework |
Ongoing Maintenance & Updates | Full dev team required | Passive (limited crypto updates) | Active protocol monitoring & updates |
Developer Experience (APIs/SDKs) | Build from scratch | Traditional finance APIs | Web3-first, chain-agnostic APIs |
Total Cost (First Year) | $250K - $750K+ | $50K - $150K + % fees | $80K - $200K (predictable) |
Strategic Control & Data | Full control | Vendor-locked, limited data | Full control, transparent data access |

Frequently Asked Questions
Get clear answers on how we integrate local payment rails like UPI, Pix, and SEPA into your Web3 application.
A standard integration for a single payment rail (e.g., UPI in India) takes 2-3 weeks from kickoff to production deployment. This includes API development, smart contract updates, and end-to-end testing. Complex multi-region deployments with 3+ methods typically take 4-6 weeks. We provide a detailed project plan with milestones during the discovery phase.
