xToken is driven by the burn mechanics of xNFT as described above. As supply of xTokens decrease, the price of xToken is designed to increase.
P=SM
Price is determined by Market Cap divided by the total supply of xToken. Thus,
P=priceM=market capS=total supply
Given that the new supply changes according to the burn mechanism of mint and trade, the denominator of the price equation can be represented as the new supply.
S1=S0−Burnm−BurntS1=new supplyS0=old supplyBurnm=supply burnt from mintBurnt=supply burnt from trade
Burnt supply from both mint and trade can be summarized by summation of all instances of mint or burn, determined by the price in xToken and burn fee at the period of action. To give burn supply of mint as an example,
i=1∑nPmiBmin=number of mintsPmi=price of mint at instance iBmi=burn fee in percentage of mint at instance i
To combine everything, we get the price appreciation equation where price is determined by the burnt supply from mint and the fees that occur from trades, as follows.
P1=S−∑i=1nPmiBmi−∑j=1mPtjBtjP0S
P1=new xToken priceP0=old xToken priceS=xToken supplyn=number of mintsPmi=price of mint at iBmi=mint burn fee in percentage at im=number of tradesPtj=price of trade at jBtj=trade burn fee in percentage at j
