Frequently Asked Questions
Get answers to common questions about our DePIN device payment gateway development, from timelines and costs to security and support.
A DePIN (Decentralized Physical Infrastructure Network) payment gateway is a blockchain-based system that enables IoT devices to autonomously accept, process, and settle payments for services rendered (e.g., EV charging, WiFi access, sensor data). You need one to create a trustless, automated revenue model for your hardware, eliminating intermediaries, reducing fees to ~1-2%, and enabling global microtransactions without traditional banking infrastructure.
