Collectible Cards

This example DApp is using a Non Fungible Token smart contract (NFT) to manage cards ownership.

Conversely to fungible token, a non-fungible token represents a unique asset and cannot be combined to another token.

The smart contract used in this DApp implements the official Tezos Financial Asset 2.0 specification.

In a nutshell it specifies that a NFT has the following entry points:

  • update_operators is used to authorize third party to transfer tokens
  • transfer is used to actually transfer ownership
  • balance_of is used to retrieve ownership information
