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

• Ethereum development standards
• Smart contracts

Token Standards

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

• ERC20 - A standard interface for tokens
• ERC721 - A standard interface for non-fungible tokens
