NFT.
A native token whose minting policy guarantees a one-of-one supply.
In depth
On Cardano an NFT is simply a native token whose minting policy forbids any further minting once the unique unit exists (or restricts supply to one). Because tokens are a ledger primitive, NFTs do not require a separate contract standard like ERC-721.
Example
A digital collectible whose minting policy is time-locked and was triggered exactly once to mint a single unit is a Cardano NFT.
