# Fraktion Supplier {% hint style="info" %} This function allows to fix automatically every week the new supply of fraktions for a given content and a given profitability {% endhint %} ### Free Fraktion Free Fraktion are minted only once when a user is consuming the content for the first time. There is no supply before the minting. ### Initial Supply The number of Fraktions for the initial drop is the same for every content : `Date 0` | Profitability | Initial Drop | Initial Price | | ------------- | ------------ | ------------- | | Common | 20 | FRK 90 | | Premium | 7 | FRK 500 | | Gold | 3 | FRK 1200 | | Diamond | 1 | FRK 3000 | ### New Supply Every week (`Date 0` + `7 days`), we check for every profitability if all the fraktions have been sold. **Case 1 : If all the fraktions haven’t been sold** No more fraktion are supplied The price of the fraktions that haven’t been minted yet is recalculated depending on the algorithm decribed [here](https://www.notion.so/Update-du-27-09-22-85d3073e47554ab5807babf20b947f77). **Case 2 : All the fraktions have been sold** New fraktions are supplied. The number of new fraktions $$n\_w$$ supplied depends on : * the number of fraktions minted during the former week * the velocity at which the fraktions were minted {% hint style="success" %} $$n\_w$$ is in the range of 80% and 200% of the number of fraktions minted the last week, $$\rho\_{w-1}$$. {% endhint %} Let $$t\_k$$ the timestamp when the fraktion $$k$$ is minted Let $$t\_0$$ the timestamp of the last weekly anniversary (when the new fraktions were supposed to be supplied the last week). $$t\_0=t-168$$. $$t\_0$$ and $$t\_k$$ are set in hour $$ n\_w=m\_{w-1}\times\bigg(80%+(200%-80%)\times \mu\_{w-1} \bigg) $$ where $$ \mu\_{w-1}=1-\frac{\sum\_{k=1}^{m\_{w-1}}(t\_k-t\_0)}{m\_{w-1}\times24\times7}=1-\left(\frac{\sum\_{k=1}^{m\_{w-1}}t\_k}{m\_{w-1}}-t\_0\right)\times\frac{1}{168} $$ Example : {% embed url="" %}
