Hydra is Cardano’s official Layer-2 scaling solution, enabling:
- Near-instant transactions (< 1 second)
- Ultra-low fees (~0.0001 ADA)
- Thousands of TPS per Head
- Full smart contract compatibility
But right now: Scattered docs, no clear learning path, and almost zero real-world DApp examples.
This tutorial closes that gap — from zero to a production-ready Hydra DApp.
