What are the different Tokens on Ethereum?

May 20, 2021 1 min read

The Ethereum blockchain was designed to support the development of decentralised applications by many different parties at the same time. To keep this ecosystem of services in harmony with itself, it is important to have certain standards of development. Hence, Ethereum contains specifications for the type of tokens that can exist on it. The most popular token standards are explained below.

ERC-20

ERC-20 (Ethereum Request for Comments - 20) is a token standard that was proposed in 2015. It is the primary standard by which a fungible token can be deployed on the Ethereum blockchain. By fungible, we mean the property which makes each token exactly the same in type and value to others of its kind. Such a standard is ideal to represent tokens needed for currency, voting, staking, etc.

ERC-721

ERC-721 (Ethereum Request for Comments - 721) is a token standard that was introduced in 2018. It is the primary standard by which a non-fungible token can be created on the Ethereum blockchain. Non-fungibility means that the token has a unique value on its own, and is not replaceable by any other. Such a standard is very useful in representing all one-off artefacts such as art, lottery tickets, special access keys, etc.
