Minting is the feature that unifies the NFT sneaker. When merging 2 NFTs of the same rank, a new NFT with the current rarity can be obtained, but the basic properties are changed or an NFT of higher rarity is obtained.
The NFT consolidation process will take time to complete. Once the merge is in progress, it cannot be cancelled.
Depending on the rank and rarity of the NFT, there are different requirements for the number of WST tokens.
It is not possible to merge 2 NFT sneakers of different rarity.
