END-TO-END DELIVERY
Our Development & Delivery Process
A structured, transparent process designed to deliver production-ready, secure, and scalable DePIN event feeds. We focus on rapid integration and long-term reliability.
01
Discovery & Architecture Design
We conduct a technical deep-dive to define your specific event types, data sources, and consensus requirements. We deliver a detailed architecture document outlining the custom pallet design, off-chain worker strategy, and integration points with your existing infrastructure.
02
Custom Pallet Development
Our Substrate experts build your dedicated event feed pallet using Rust, implementing secure data structures, permissioned submission logic, and efficient on-chain storage. We follow Parity's best practices and integrate with standard FRAME pallets for security and interoperability.
03
Off-Chain Worker Integration
We develop and deploy the critical off-chain component that fetches, validates, and submits real-world data (IoT sensors, APIs, oracles) to your blockchain. This includes cryptographic signing, data formatting, and robust error handling for 24/7 uptime.
04
Rigorous Testing & Security Audit
Every line of code undergoes unit, integration, and stress testing. The final pallet and off-chain worker receive a comprehensive security review by our internal audit team, focusing on logic flaws, economic attacks, and data integrity vulnerabilities before mainnet deployment.
05
Deployment & Node Configuration
We handle the complete deployment of your custom blockchain node or parachain, including validator setup, RPC endpoint configuration, and monitoring stack integration (Prometheus, Grafana). We ensure a smooth transition from testnet to mainnet.
06
Documentation & Handover
You receive complete technical documentation, including pallet APIs, runtime configuration guides, and operational runbooks. We provide knowledge transfer sessions for your engineering team and ongoing support options for maintenance and scaling.

Frequently Asked Questions
Get clear answers on our process, timeline, and technical approach for building custom Substrate pallets for DePIN event feeds.
A standard pallet with core event sourcing and on-chain verification takes 3-5 weeks from spec to testnet deployment. Complex integrations with multiple off-chain data sources or custom consensus mechanisms can extend to 8-10 weeks. We provide a detailed sprint-by-sprint timeline after the initial discovery workshop.
