# 10.2 Supply & Demand Design (Why Balance Is Stable)

#### **Supply-side Measures**

* **EVT Pools**: Pre-allocated pools released gradually.
* **Excavation Right NFTs**: Expiration and cost mechanics prevent monopolization.

#### **Demand-side Measures**

* **Lifespan/HP recovery** (spending MANEKINEKO NFT/EVT/Econ).
* **Breeding & upgrades** (Econ / EVT / Taiyaki).
* **Event initiatives** (create temporary bursts of demand).
