The Infrastructure Decision for FinTech Leaders
Build vs. Buy: Chainscore API vs. Traditional Providers
A direct comparison of the total cost, risk, and time investment required to build a cross-border remittance system in-house versus implementing Chainscore's production-ready API.
| Key Factor | Build In-House | Chainscore API | Traditional SWIFT/Correspondent Banking |
|---|---|---|---|
Time to First Transaction | 6-12+ months | 2-4 weeks | 3-6 months |
Upfront Development Cost | $250K - $750K+ | $0 (Pay-as-you-go API) | $50K - $200K (Integration) |
Compliance & Licensing Burden | High (Your responsibility) | Built-in (We are the licensed entity) | High (Your responsibility) |
Settlement Speed | Variable (Depends on build) | < 60 seconds (On-chain finality) | 2-5 business days |
Transaction Cost (Avg. $1K Transfer) | $15 - $50 (Gas + Liquidity) | $5 - $15 (All-inclusive fee) | $30 - $80 (Fees + FX spread) |
Technical & Security Risk | High (Unaudited custom code) | Low (Audited, battle-tested system) | Medium (Legacy system integration risk) |
Ongoing Engineering & DevOps | 2-3 FTE Engineers ($300K+/year) | Fully managed by Chainscore | 1-2 FTE for maintenance & support |
Global Liquidity Access | Requires separate partnerships | Pre-integrated global network | Requires direct bank relationships |
FX Rate Transparency | You must source rates | Real-time, transparent mid-market rates | Opaque, with hidden spreads |
Supported Corridors | Build per corridor | 50+ major corridors at launch | Limited by banking relationships |
