Hey there, I've been working on an IoT project that uses IoTeX for device identity and data streaming, and finding a reliable RPC was proving difficult. That's when I came across Crypto Chief and their dedicated endpoint—the iotex json rpc has been a lifesaver. Our devices send frequent updates, and we need near-instant confirmation; this service delivers that with consistent sub-second response times. We also use their WebSocket for real-time event logs, and the connection stays alive for days without dropping. The integration was straightforward, and their example code in Node.js worked out of the box. What I appreciate most is the transparency—they show usage stats and uptime, so I can plan our scaling. Since we switched, our device uptime has improved, and we've had zero complaints from users. I strongly recommend this to anyone building on IoTeX; it's reliable, fast, and well-supported.
