A “non-fungible token” (NFT) is a digital asset that cannot be exchanged for cash. That something is non-fungible indicates that it is irreplaceable in its particular form. Contrarily, fiat and digital currencies can be freely swapped for one another because of their fungibility. Because each NFT is digitally signed, they are all one-of-a-kind. Non-tangible assets (NFTs) are digital content like pictures, movies, or music. Artwork, comic books, sports memorabilia, trading cards, games, and more are all instances of NFT.
