Frequently Asked Questions for DePIN Developers
Get clear answers on integrating our hardware-secure SDK for DePIN and IoT applications, from timelines to security.
A standard integration for a new IoT device or DePIN node takes 2-4 weeks from kickoff to production-ready firmware. This includes provisioning, key management module integration, and initial testing. Complex multi-device ecosystems or custom consensus mechanisms may extend to 6-8 weeks. We provide a detailed project plan in the first week.
