NFTs are one-of-a-kind. The largest NFT platform is OpenSea. Nonfungible tokens, like crypto currencies, demonstrate ownership of digital assets such as images, sound files, or text. Anything that is 'fungible' suggests that it can be replaced with something comparable. As a result, a fungible token is any token that can be replaced with something comparable. As a result, NFTs are distinct and cannot be interchanged under any circumstances.
