Custom Pallet vs. External Oracle Networks
A technical comparison of building a custom oracle pallet versus integrating an external network for your Substrate-based blockchain.
| Architectural Factor | Build Custom Oracle Pallet | Integrate External Oracle Network |
|---|---|---|
Time to Production | 8-16 weeks | 2-4 weeks |
Initial Development Cost | $80K - $200K+ | $15K - $50K |
Data Source Flexibility | Full control & customization | Limited to provider's feeds |
Protocol Security | Your team's responsibility | Provider's audited, battle-tested code |
Network Consensus Overhead | Minimal (native to chain) | High (external consensus + bridge) |
Settlement Finality | Instant (on-chain) | Delayed (cross-chain confirmation) |
Ongoing Maintenance | Requires dedicated DevOps | Managed by provider (optional SLA) |
Total Cost of Ownership (Year 1) | $250K+ | $50K - $120K |

A PROVEN FRAMEWORK
Our Development & Integration Process
We deliver production-ready, secure oracles using a structured, transparent process designed for rapid integration and long-term reliability. Our methodology ensures your custom pallet aligns perfectly with your blockchain's architecture and business logic.
01
Discovery & Architecture Design
We conduct a deep technical workshop to map your data requirements, consensus model, and integration points. We define the pallet's data structures, security boundaries, and economic incentives to ensure optimal on-chain performance.

Frequently Asked Questions
Get clear answers on our process, timelines, and security for building custom oracles on Substrate.
A standard, production-ready oracle pallet with 2-3 data sources and on-chain verification takes 4-6 weeks from kickoff to mainnet deployment. Complex systems with custom aggregation logic or cross-chain capabilities can extend to 8-12 weeks. We provide a detailed sprint-by-sprint timeline during the initial technical scoping.
