# NFT We are a fan of hearthstone produced by Blizzard, in which, the card can be divided into four categories based on the quality: common, rare, epic, and legendary. Legendary cards are the most valuable and powerful ones. When you purchase a card pack, you don't know what cards you will get before you open them. We want to move this brilliant idea into blockchain with the help of smart contracts and NFT. ButterSwap's NFT system is designed to provide both joy and profit to the users. It contains the following major components: * [Blind Box](/products/nft/blind-box.md) * [Dinner Table](/products/nft/dinner-table.md) * [Auction Market](/products/nft-auction-market-1.0.md) The major circulating token in the NFT system is BUTTER and inside the system, there are multiple scenarios in which BUTTER will be burnt automagically. --- # 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.
