# NFTs System

NFTs are the core assets within EtherForge. Every in-game element including factories, heroes, monsters, and equipment exists as on-chain NFTs, providing true ownership, interoperability, and free trade for all players.

## 1/ ValorForge and MonstroForge

All factories mine $ETHER, the game’s base energy resource, and generate bio-core cocoons that hatch into unique Hero or Monster NFTs with randomized stats and abilities.

### Supply

|     NFT Type     | Total Supply |
| :--------------: | :----------: |
|  **ValorForge**  |    20,000    |
| **MonstroForge** |    20,000    |
|  **ProtoForge**  |    20,000    |
|   **CoreFore**   |    20,000    |
|     **Total**    |    80,000    |

Once all 80,000 Forge NFTs are sold, they become fully tradable on-chain through any Solana compatible NFT marketplace.

## 2/ Heroes and Monsters

Heroes and Monsters are the main character NFTs of EtherForge, created from ValorForge and MonstroForge. They are not just collectibles. They are combat-ready assets used in Ether Arena for real-time PvP battles.

### Supply

|   NFTs Type  | Total Supply |
| :----------: | :----------: |
|  **Heroes**  |    40,000    |
| **Monsters** |    40,000    |
|   **Total**  |    80,000    |

All character NFTs are on-chain assets, granting full ownership, trading, transfer, and auction rights to players. Owning rare, high-stat, or exclusive-skin NFTs provides both combat advantages and investment value within the ecosystem.

## 3/ Rarity and Value Growth

Each Hero and Monster NFT belongs to one of the following rarity tiers:

$$
Rare → Epic → Legendary → Mythic
$$

Higher rarity NFTs offer:

* Stronger combat attributes
* Higher win rates in Ether Arena
* Higher market demand and investment potential

Upgrading and training allow NFTs to evolve into stronger forms, increasing both their combat power and long-term asset value.
