- Delivery: Full test suite, deployment scripts, and technical documentation included.
Technical & Commercial Insights
DePIN Marketplace Development FAQs
Get clear, specific answers to the most common questions CTOs and founders ask when evaluating a DePIN marketplace development partner.
Our standard deployment for a core DePIN marketplace MVP is 4-6 weeks. This includes sensor data ingestion, tokenized asset creation, a basic order book, and wallet integration. The process follows a clear 4-phase methodology: 1) Discovery & Architecture (1 week), 2) Smart Contract & Core Logic (2-3 weeks), 3) Frontend & Integration (1-2 weeks), 4) Testing & Deployment (1 week). For complex integrations with legacy IoT systems or custom consensus mechanisms, timelines extend accordingly with clear milestones.
