NFTs (Non-fungible tokens) are unique digital assets representing real-world items, such as photos, music, videos, and trading cards. They are managed in a digital ledger and bought and sold online.

For example, rather than purchasing an actual photograph to display on a wall, the buyer receives an original digital file. Any digital asset such as a piece of collectible digital characters, virtual real estate, or original social media posts, can be created and purchased as an NFT.
