Architecture Decision Analysis
Direct Integration vs. Third-Party Widgets
A technical and business comparison for CTOs and engineering leads evaluating Solana fiat on-ramp integration strategies.
| Feature | Direct Rust Integration | Third-Party Widget (e.g., MoonPay) |
|---|---|---|
Integration Complexity | High (Rust/Anchor expertise) | Low (JavaScript SDK) |
Time to Market | 6-12 weeks | 1-2 weeks |
Custody & Compliance | Your responsibility | Handled by provider |
Fee Control & Margins | Direct access to interchange (0.5-1.5%) | Provider markup (3-5% total) |
User Experience Control | Full UI/UX customization | Limited to provider template |
Protocol-Level Features | Native support for SPL tokens, custom logic | Generic, token-agnostic flows |
Security Audit Surface | Your smart contract & backend | External provider dependency |
Ongoing Maintenance | Your team (updates, monitoring) | Minimal (provider handles updates) |
Total Cost (First Year) | $75K-$150K (dev + audit) | $0 upfront + 20-30% of revenue share |
Strategic Value | Core competency, defensible moat | Fast validation, operational dependency |
