Standards overview

The Ethereum community has adopted many standards that help keep projects (such as Ethereum clients and wallets) interoperable across implementations, and ensure smart contracts and dapps remain composable.

Typically standards are introduced as Ethereum Improvement Proposals (EIPs), which are discussed by community members through a standard process(opens in a new tab).

Types of standards

There are 3 types of EIPs:

Furthermore, the Standard Track is subdivided into 4 categories:

More detailed information on these different types and categories can be found in EIP-1(opens in a new tab)

Token standards

  • ERC-20 - A standard interface for fungible (interchangeable) tokens, like voting tokens, staking tokens or virtual currencies.
    • ERC-1363(opens in a new tab) - Defines a token interface for ERC-20 tokens that supports executing recipient code after transfer or transferFrom, or spender code after approve.
  • ERC-721 - A standard interface for non-fungible tokens, like a deed for artwork or a song.
  • ERC-777 - (NOT RECOMMENDED) A token standard improving over ERC-20.
  • ERC-1155 - A token standard which can contain both fungible and non-fungible assets.
  • ERC-4626 - A tokenized vault standard designed to optimize and unify the technical parameters of yield-bearing vaults.
