Non-fungible token

A non-fungible token or NFT is a special type of a token, that represents some unique object.

Two regular tokens cannot be distinguished from each other — they are alike, i.e. fungible. Each NFT token is unique, and therefore NFTs are non-fungible. Any two NFTs can always be distinguished.

Every NFT has a unique ID.

NFTs are most commonly used in games.

Issue of non-fungible tokens

The issue of a single non-fungible token is made by an issue transaction; for such a transaction, the value of the "Amount" field equals 1, and the values of the fields "Number of decimal places" and "Reissue flag" equal 0.

To issue NFTs you can use the waves-games npm package.

The fee for the issue of a single NFT is 0.001 WAVES.
