In preparation
NFT cards giveaway to members and non-members
NFT cards can be giveaway to members and non-members just like trading cards.
We can also develop a system to release contents only to members who own specific NFTs.

Examples of requirements
Select multiple images on the management screen and register them as NFTs in a batch, then giveaway the issued NFTs sequentially according to the default triggers specified on the management screen.
