# Minting

### Minting Mechanism

The user can produce two shoes NFTs (previous generation) and new shoes NFTs (post generation) at a certain cost. At this time, the two shoes NFTs used in minting are remained without disappearing. In addition, all shoes used in the minting must be Level 10 or higher.

The features (types, ratings, generations) of the new generation shoes are determined by the features of the previous generation shoes. Types and grades are determined by probability, and generations are determined by a set mechanism. In addition, later generation shoes are less likely to be used in minting than previous ones, and costs more to mint above a certain threshold.

The conditions for minting are as follows.

* Only shoes above level 10 are available for minting.
* Minting time is determined by the shoes with higher grades.
  * Normal: 6hours (Boosting Cost: 36 $WALK)
  * Rare: 24hours (Boosting Cost: 144 $WALK)
  * Epic: 48hours (Boosting Cost: 288 $WALK)

### Features of Minted Shoes NFT

#### (1) Generation of Shoes Minted

The generation of the minted shoes NFT is decided by the higher generation among the parent’s, +1.
