# Content-Minting

For each piece of work, as soon as the Creator is signing in in **The Sybel Ecosystem**, a NFT is minted, owned by the Creator, present in the Creator's custodial wallet. 

By burning TSE and SMT, Creator can supply some fractions of this NFT with different rarities : 

* Legendary
* Epic
* Rare
* Common
* Standard

One **Standard Token** is automatically minted for free as soon as a User claim it after having interacted with the content. 

For the rest of the different types of fraction, Creator must burn :

<table><thead><tr><th width="150">Rarity</th><th width="164">Tokens burned to supply one fraction</th></tr></thead><tbody><tr><td>Legendary</td><td>200 SMT</td></tr><tr><td>Epic</td><td>100 SMT</td></tr><tr><td>Rare</td><td>50 SMT</td></tr><tr><td>Common</td><td>10 SMT</td></tr><tr><td>Standard</td><td>0</td></tr></tbody></table>

Every fraction is minted once bought by a User or an Investor. **The Initial Price** is the same for each Creator and for each work. It is defined as below :&#x20;

<table><thead><tr><th></th><th width="243.73033707865167">Initial Price</th></tr></thead><tbody><tr><td>Legendary</td><td>400 SMT</td></tr><tr><td>Epic</td><td>200 SMT</td></tr><tr><td>Rare</td><td>100 SMT</td></tr><tr><td>Common</td><td>20 SMT</td></tr><tr><td>Standard</td><td>One for Free</td></tr></tbody></table>

**Fraction Price Index Formula**

The Current Price (CP) of a fraction a Content *i* with a rarity *j* is recalculated every week depending on different variables :&#x20;

$$
CP\_{ij}(w)=CP\_{ij}(w-1) \times \left( x + \cfrac{\sum\_{k=1}^{w-1}\rho\_{ij}(k)}{\sum\_{k=1}^{w-1}\sigma\_{ij}(k)}\right)^{\left(y+ \cfrac{\rho\_{ij}(w-1)}{\rho\_{ij}(w-2)}\right)}
$$

$$w$$: current week\
$$\rho(k)$$***:*** number of fractions minted during week *k*\
$$\sigma(k)$$​: number of fractions supplied during week *k*\
$$x, y$$​: System Parameter<br>

Creators can choose to supply their fraction at once or within a defined period of time. The Current Price is always ta the moment of the minting.&#x20;
