# Trading and marketplace Players can buy and sell items through the open marketplace system in Ukiyo, including in-game supported NFT items such as cosmetics and pets. Each trade is subject to a transaction fee, which helps to counter the inflationary nature of gold coins. #### **Token integration** The Ukiyo token serves as the primary currency for the in-game NFT marketplace. Consequently, transaction fees for NFT trades are paid in Ukiyo tokens, with a portion of these fees being burned. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
