You can. In other words, through the electronic wallet, users can check not only information about various game services, but also information about items they own in specific game services.

In addition, the token management server 340 can provide the user with a function to mint the user's items with tokens in the electronic wallet. As explained earlier, this function can be based on the premise of providing information about the user's items to the user through the electronic wallet. Additionally, the user's items can be created into NFT (Non-Fungible Token) through minting.

At this time, NFTs or game tokens created for in-game items such as game services that the user no longer uses or game services that have been terminated will no longer be used. The token management server 340 can provide a function to recycle NFTs or game tokens that users no longer use. For example, the token management server 340 provides a token recycling function that can generate new tokens (NFTs or game tokens) that can be used in other games and provide them to the user while burning the tokens (NFTs or game tokens) selected by the user. can do.

Figure 5 is a diagram illustrating an example of the concept of a token recycling function in one embodiment of the present invention. Figure 5 shows that when tokens 510 to 540 selected by the user are put into the recycling machine 500 and the recycling machine 500 is operated, the inserted tokens 510 to 540 are incinerated and can be used in other games.
