Strategic Decision Analysis
Build vs. Buy: Cross-Chain Oracle Integration
A detailed comparison of the total cost, risk, and resource commitment required for developing a custom cross-chain oracle system versus leveraging Chainscore's managed service.
| Factor | Build In-House | Chainscore Integration |
|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks |
Initial Development Cost | $250K - $600K+ | $25K - $75K |
Annual Maintenance Cost | $150K - $300K (2-3 FTEs) | Optional SLA from $50K/year |
Security & Audit Burden | High (unaudited custom code) | Low (pre-audited, battle-tested modules) |
Supported Chains (Initial) | 1-2 chains (custom per chain) | Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche |
Data Feed Flexibility | Limited to initial design | On-demand addition of 1000+ price feeds & custom data |
Uptime & Reliability SLA | Your team's responsibility | 99.9% SLA with 24/7 monitoring |
Team Expertise Required | Senior Solidity, DevOps, Cryptography | Your existing Web3 devs + our integration support |
Total Cost of Ownership (Year 1) | $400K - $900K+ | $75K - $125K |
Critical Path Risk | High (delays, security flaws, attrition) | Low (defined scope, guaranteed delivery) |
