Trading System

The NFT trading market is where players trade NFTs. Players can freely sell their NFTs (Sea Elf Sea Elf Egg Gem) to get DUW, or pay DUW to buy what they need from the NFT trading market, and each trading market charges 5 % transaction gas fee. Purchase and sale of Sea Elf, Sea Elf Egg and Gem, some examples are as follows:
Sea Elf purchase: All Sea Elf, after purchase, need to cool down for 24 hours. During the cooldown period, you cannot participate in the game, but it does not affect the sale.
Gem purchase: After gem purchase, you need to unbind it in the backpack to enter the game balance account.
Gem sale: Gem can be sold by custom quantity (must be an integer).
