# NFTs **Non-fungible tokens** (NFTs) are types of digital assets that are unique and not interchangeable. Each NFT contains a specific piece of data that distinguishes it from any other NFT, giving it a distinct identity and value. NFTs can be used to represent various types of digital assets, such as artwork, music, videos, and even tweets, and are often bought and sold on blockchain-based marketplaces. NFTs are created using blockchain technology, which ensures that they are secure and transparent. Each NFT is stored on a blockchain as a digital record that cannot be altered or duplicated, making them valuable as collectibles or investments. NFTs are often bought and sold using cryptocurrencies, and the ownership of an NFT can be easily transferred from one person to another. NFTs remain a popular and rapidly growing market within the broader world of blockchain and cryptocurrency. --- # 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.
