# Start and build factory

<figure><img src="/files/yWIFqZEYhUS77ToIhOXL" alt=""><figcaption></figcaption></figure>

There are four primary types of machines:

* ValorForge (total supply: 20,000): Produces Heroes and $ETHER
* MonstroForge (total supply: 20,000): Produces Monsters and $ETHER
* ProtoForge (total supply: 20,000): is positioned as a lightweight entry option, priced at 10 USDC, producing 2 $ETHER per day at level 1.
* CoreForge (total supply: 20,000): sits a tier above, priced at 20 USDC, with 4 $ETHER per day at level 1 and higher rarity potential.

{% hint style="info" %}
$ETHER can be converted into $GENESIS, which is the main token in the EtherForge economy.
{% endhint %}

| Machine Type | Price ($USDC) | Total Supply |
| :----------: | :-----------: | :----------: |
|  ValorForge  |       50      |    20,000    |
| MonstroForge |       50      |    20,000    |
|  ProtoForge  |       10      |    20,000    |
|   CoreForge  |       20      |    20,000    |

Heroes and Monsters are essential for the real-time PvP Battle mode. They exist as NFTs and can be freely traded on the marketplace.

Each machine functions as an automated production line, generating Heroes or Monsters and producing $ETHER, which can be converted into $GENESIS energy, the core resource of the EtherForge universe. Once all 80,000 machines are sold out, machines will become tradable on-chain assets.\ <br>
