Build vs. Buy: The Real-Time Conversion Decision
A detailed comparison of the total cost, risk, and time associated with developing a real-time fiat on/off-ramp in-house versus leveraging Chainscore's production-ready engine.
| Key Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to Market | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $50K - $150K |
Ongoing Annual Maintenance | $150K - $300K | Optional SLA ($30K - $75K) |
Security & Compliance Risk | High (unaudited, self-managed) | Low (audited, SOC 2 compliant) |
Payment Provider Integrations | Manual (Stripe, Plaid, etc.) | Pre-integrated & managed |
FX & Liquidity Management | Your team's responsibility | Managed by Chainscore |
Smart Contract Audit Coverage | Your cost & timeline | Included & regularly updated |
Uptime & Reliability SLA | Your responsibility | 99.9% guaranteed |
Regulatory Updates (Travel Rule, AML) | Your legal team's burden | Handled by our compliance layer |
Team Composition Required | 5-10+ Sr. Engineers, Legal, Ops | 1-2 Integration Engineers |
Our Delivery Methodology
We deliver production-ready fiat on-ramps with a structured, transparent approach that minimizes your time-to-market and technical risk.
Architecture & Integration Design
We map your specific payment corridors and user flows to design a compliant, scalable integration. This includes selecting optimal PSPs, defining settlement logic, and planning for KYC/AML data flows.
Smart Contract Development
Our engineers build secure, gas-optimized smart contracts for fund routing, escrow, and settlement. All contracts follow OpenZeppelin standards and are written in Solidity 0.8+.
Backend & API Development
We develop the core engine: transaction orchestration, webhook handlers for PSP events, real-time rate aggregation, and a fully documented REST/WebSocket API for your frontend.
Compliance & Security Hardening
We implement mandatory KYC checks, fraud detection rules, and transaction monitoring. The entire system undergoes internal security review and is prepared for external audit.
Staging & Client Testing
We deploy to a dedicated staging environment with testnet funds and sandbox PSP accounts. You receive full access to test end-to-end flows, review dashboards, and approve the build.
Production Deployment & Handoff
We manage the production deployment, configure live PSP keys, and set up monitoring/alerting. The complete codebase, documentation, and operational runbooks are delivered to your team.
