What Is ERC20 and What Does It Mean for Ethereum?

In the most basic sense, ERC20 is a standard interface for tokens on the Ethereum blockchain. By implementing a few simple functions, a token can be interoperable with other ERC20 tokens and take advantage of the network effects of the Ethereum ecosystem.

ERC20 defines a common list of rules for all Ethereum tokens to follow, allowing developers to program how new tokens will function within the larger Ethereum system. These rules include how the tokens are transferred, how users can access them, and how data within each token is accessed.

The benefits of having a standard interface are numerous. For example, it allows different tokens to be easily swapped or exchanged for one another without the need for a centralized exchange.

This can be done through so-called “decentralized exchanges” (DEXes), which are powered by smart contracts.

It also allows third-party services to be built on top of Ethereum that can interact with all ERC20 tokens in a consistent way. This could be anything from wallets to decentralized applications (dapps) to exchanges.

One of the most important benefits of ERC20 is that it brings some much-needed standardization to the Ethereum ecosystem. Up until now, there has been a lot of fragmentation in how different tokens are built and operated.

This has made it difficult for users and developers to interact with multiple tokens in a consistent way.

ERC20 brings some much-needed structure to Ethereum and will make it easier for users and developers to interact with the growing number of tokens being built on the platform. In the long run, this should help accelerate innovation and adoption of Ethereum-based technologies and applications.
