Strategic Decision Matrix
Build vs. Buy: Custom Integration vs. Generic Middleware
A technical and financial comparison of developing a custom integration in-house versus using Chainscore's enterprise-grade middleware for connecting legacy systems to blockchain networks.
| Integration Factor | Build In-House | Generic Middleware | Chainscore Custom Integration |
|---|---|---|---|
Time to Production | 6-12+ months | 2-4 months | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $50K - $150K | $75K - $200K |
Security & Audit Burden | High (Your responsibility) | Medium (Vendor's base layer) | Low (Pre-audited patterns + custom audit) |
Legacy System Connectors | Custom build required | Limited pre-built options | Pre-built for SAP, Oracle, Salesforce + custom |
Smart Contract Upgradability | Your team implements | Not typically supported | Built-in upgrade patterns & governance |
Ongoing Maintenance & DevOps | Full internal team required | Vendor manages middleware only | Full SLA: monitoring, alerts, patching |
Protocol & Chain Flexibility | Locked to initial design | Limited to vendor's stack | Multi-chain (EVM, L2s) & future-proof |
Compliance & Reporting | Custom development needed | Basic logs only | Built-in compliance hooks & audit trails |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $100K - $250K | $150K - $300K |
Guaranteed Uptime SLA | None (your infrastructure) | 99.5% | 99.9% |

What CTOs and Technical Leaders Ask
Enterprise Blockchain Integration: Key Questions
Based on 50+ enterprise integrations, here are the most common questions we receive about connecting legacy systems to blockchain infrastructure.
Standard integrations take 2-4 weeks from kickoff to production. For a typical ERP or CRM system with 3-5 core data flows, we deliver a production-ready MVP in 3 weeks. Complex multi-system integrations with custom oracles can extend to 6-8 weeks. We provide a detailed sprint-by-sprint timeline during the discovery phase.
