Token Standards

Introduction

One of the many Ethereum development standards focus on token interfaces. These standards help ensure smart contracts remain composable, so for instance when a new project issues a token, that it remains compatible with existing decentralized exchanges.

Prerequisites

Token standards

Here are some of the most popular token standards on Ethereum:

  • ERC-20 - A standard interface for fungible (interchangeable) tokens, like voting tokens, staking tokens or virtual currencies.
  • ERC-721 - A standard interface for non-fungible tokens, like a deed for artwork or a song.
