| **SSR (Super Super Rare)** | 200 NFTs                                           | Unique visuals         | **Yield Node NFT** — eligible for platform-level revenue sharing                                 |
| **SR (Super Rare)**        | 2,000 NFTs                                         | Unique visuals         | **Yield Node NFT** — eligible for platform-level revenue sharing                                 |
| **R (Rare)**               | 20,000 NFTs                                        | Unique visuals         | **Yield Node NFT** — eligible for platform-level revenue sharing                                 |
| **N (Normal)**             | 50,000 NFTs+ (dynamically scaled with user growth) | Procedurally generated | **Access Pass NFT** — enables entry into Play-to-Earn gameplay; not eligible for revenue sharing |

**📌 Notes:**

* **SSR / SR / R NFTs** are classified as **node-tier assets** — granting holders a proportional share of platform-generated revenues through structured staking mechanics.
* **N (Normal) NFTs** function as **access credentials**, unlocking participation across all Multi-Earn systems, but **do not carry any yield or revenue sharing.**
