What Is ERC?
ERC, short for Ethereum Request for Comment, comes in many forms, including registries, package formats, libraries, and token standards. Since Ethereum is an open-source protocol, anyone with knowledge of Solidity can submit their own ERC. However, not every new ERC version gets approved, as it is the original creator’s responsibility to explain their ERC properly to the community and garner support.
- ERC-20 — One of the most common ERC types, it is what most tokens on Ethereum use.
- ERC-777 — Aiming to improve upon the ERC-20 token functionality, ERC-777 is less common and also comes with additional risks, such as more susceptibility to malicious attacks.
- ERC-721 — This standard is used for non-fungible tokens (NFTs).
Benefits of ERC
- ERC tokens help developers by giving them a base of proven code — rather than from scratch — when building projects.
- As token standards, the ERC group allows projects to be deployed faster because they follow a certain template (i.e., standard).
