Strategic Infrastructure Decision
Build vs. Buy: Custom SDK vs. Generic Oracle
A direct comparison of the resource investment and risk profile for building an oracle solution in-house versus partnering with Chainscore for a custom, AppChain-specific SDK.
| Key Factor | Build In-House | Generic Oracle Service | Chainscore Custom SDK |
|---|---|---|---|
Time to Initial Integration | 6-12 months | 2-4 weeks | 4-8 weeks |
AppChain-Specific Logic | Full custom control | None (one-size-fits-all) | Designed for your consensus & state |
Upfront Development Cost | $250K - $750K+ | $0 - $50K (API fees) | $80K - $200K |
Ongoing Security & Maintenance | Your team's responsibility | Vendor's responsibility (shared risk) | Managed SLA with 99.9% uptime |
Data Source Flexibility | Full control | Limited to vendor's feeds | Custom feeds, APIs, & cross-chain data |
Latency & Finality Optimization | Possible with significant R&D | Generic, chain-agnostic | Optimized for your chain's block time |
Smart Contract Audit Burden | High (you must fund & manage) | Vendor's audit covers their contracts | Included in delivery |
Total Cost of Ownership (Year 1) | $300K - $1M+ | $60K - $150K (scaling fees) | $100K - $250K (predictable) |
Team Requirements | 3-5 senior blockchain engineers | 1-2 integration developers | 1 product owner + our engineering team |

Frequently Asked Questions
Get clear answers on our development process, security, and support for your custom oracle solution.
A standard, production-ready Oracle SDK for a single AppChain takes 4-6 weeks from kickoff to deployment. This includes architecture design, core data feed development, security audits, and integration testing. Complex multi-chain oracles with custom logic can extend to 8-12 weeks. We provide a detailed sprint-by-sprint timeline during the initial discovery phase.
