For example, the users can obtain a rare item from the Game on BORA and can convert this to NFT. This NFT can be placed in the Vault of the Guild that the relevant user belongs to, and as a reward for this, the user can receive NFTs or interest. Another user can, by using Digital Human Star’s NFT PFP Fantoken, vote on the Star’s performance date and purchase the Fantoken specific NFT. A limited-edition NFT can be used to apply to the NFT Liquidity Service to receive interest, and this interest can be used to accumulate various Digital Assets again.
