ERC-721

ERC-721 tokens are (different from the ERC-20 tokens) non-fungible. This means that a ERC-721 token cannot be used as money and can thus not be exchanged with another cryptocurrency on an exchange either. ERC-721 are mostly used as collectibles (a little like totally unique hockey cards). ERC-721 tokens were introduced in 2017.
