Slots
Slots are used for PROD and DEAL.
They can contain Printer, Henchman, Bag, and Vehicle.
In each slot, only one NFT can be assigned, and each NFT can be associated with only one slot.
For ease of monitoring and future development, it will be necessary to transfer the NFT with a specific MEMO to the contract. The contract will then record who owns the NFT, allowing it to be used within the game.
The NFT temporarily becomes the property of the contract and cannot be returned if locked during various phases of the game.
