Webhooks aren’t just for Stripe and GitHub. In this video, I build a real-world IoT dog treat dispenser that throws a treat every time my Solana wallet receives SOL.
This is a beginner-friendly DePIN (Decentralized Physical Infrastructure) project designed for Web2 developers who want to understand how blockchain events can trigger real physical actions—using tools you already know: APIs, webhooks, and hardware.
What you’ll learn: • What DePIN means (and why it matters) • How to listen for Solana wallet activity • How to set up a webhook for on-chain events • How to trigger an IoT device when a payment hits your wallet • How this pattern applies to real-world DePIN apps (machines, sensors, networks)
If you’re a developer who’s curious about crypto but doesn’t want to start with NFTs, this is a practical build that makes Solana feel like just another backend event source.
