# What is a Collectible/NFT? Collectibles, often referred to as NFTs (Non-Fungible Tokens). Compared with BTC, ETH, and other fungible assets, NFTs are unique and indivisible assets. For example, Cryptokitties, tokenized digital tickets, etc. are all in the NFT category. Due to their non-homogeneity and inseparability, NFTs can anchor the concept of goods in the real world, such as tokenized tickets, high-value wine, and jewelry with unique designs. --- # 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.
