Infrastructure Decision Matrix
Build vs. Buy: Custom Oracle Network vs. Generic Feeds
A technical and economic comparison of developing a bespoke oracle solution in-house versus implementing Chainscore's managed cross-chain oracle network.
| Key Factor | Build In-House | Generic Public Feeds | Chainscore Managed Network |
|---|---|---|---|
Time to Production | 6-12+ months | 1-2 weeks | 4-8 weeks |
Initial Development Cost | $250K - $750K+ | $0 (integration only) | $50K - $200K |
Annual Maintenance & Ops | $150K+ (team of 3-5) | N/A (vendor-managed) | $30K - $100K (SLA) |
Security Posture | Your responsibility (high risk) | Shared risk (public attack surface) | Audited, insured, dedicated nodes |
Data Customization & Logic | Full control | Limited to public datasets | Tailored sources, aggregation, and logic |
Cross-Chain Native Support | Requires custom bridges/adapters | Limited (often chain-specific) | Built-in for 15+ L1/L2 chains |
Uptime & Reliability SLA | Your team's burden (no SLA) | Best-effort (no guarantees) | 99.9% with financial penalties |
Response Latency | Variable (your infra) | Variable (network congestion) | < 2 seconds (guaranteed) |
Regulatory & Compliance | Your full liability | Minimal vendor accountability | KYC/AML-ready node operators, audit trails |
Team Expertise Required | Solidity, DevOps, Cryptography, Security | Basic Web3 integration | Integration engineering only |

PREDICTABLE, TRANSPARENT, AND RESULTS-DRIVEN
Our 4-Phase Delivery Methodology
We de-risk your cross-chain oracle integration with a structured, milestone-based approach. Each phase delivers tangible value, ensuring alignment with your technical and business goals from discovery to production.
01
Phase 1: Discovery & Architecture Design
We conduct a deep technical audit of your data requirements, target chains, and security model. Deliverables include a detailed architecture blueprint, data source mapping, and a risk assessment report to establish a clear project foundation.

Phase 2: Smart Contract & Node Development
Our team builds and unit-tests the core oracle smart contracts and off-chain node software. Development follows OpenZeppelin standards and includes gas optimization reports and initial internal security reviews.

Phase 3: Security Audit & Testnet Deployment
We engage a top-tier third-party auditor (e.g., Trail of Bits, Quantstamp) for a comprehensive review. Simultaneously, we deploy and stress-test the full oracle network on multiple testnets to validate performance and reliability under load.

We follow a structured 4-phase process: 1) Discovery & Design (1 week): We define requirements, data sources, and target chains. 2) Core Development (2-3 weeks): We build and test the oracle smart contracts and off-chain infrastructure. 3) Security Audit & Staging (1-2 weeks): Independent audit and deployment to a testnet. 4) Mainnet Launch & Support (1 week). Most projects deploy a production-ready, audited oracle network in 5-7 weeks.
