What is EIP (Ethereum Improvement Proposal)?
An EIP (Ethereum Improvement Proposal) is a design document proposing changes to the Ethereum protocol — including new features, standards, and processes — following a structured process for community review and adoption.
WHY IT MATTERS
EIPs are how Ethereum evolves. From token standards (EIP-20/ERC-20) to protocol upgrades (EIP-1559 fee reform, EIP-4844 blob transactions) to account abstraction (EIP-4337), all significant changes go through the EIP process.
EIP types include: Standards Track (protocol changes, token standards), Meta (process changes), and Informational (guidelines). ERCs (Ethereum Request for Comments) are a subset of Standards Track EIPs defining application-level standards.
The process: draft → review → final → adopted. Community discussion, technical review, and testnet deployment happen along the way. Anyone can propose an EIP, but adoption requires broad consensus.
