The NFT Swap service allows users to input NFTs they own into a swap pool to receive new NFTs in order to acquire new NFTs.
The NFTs required for swapping in each pool and the types of NFTs that can be obtained may vary from pool to pool, and NFTs can be obtained based on probability depending on the number of NFTs in each pool. In general, you will receive NFTs that are worth more than the NFTs you put in.
