Introduction to EIP and ERC
Terms like ERC20 and ERC721 are frequently mentioned in the blockchain space, especially when discussing token standards for ICOs or NFTs. But what exactly do these acronyms mean, and how do they relate to Ethereum's development? This guide breaks down the origins of ERC and explains the role of EIP in Ethereum's ecosystem.
EIP: Ethereum Improvement Proposals
Definition and Purpose
EIP (Ethereum Improvement Proposals) are design documents that provide information to the Ethereum community or propose new features/environments for Ethereum. Each EIP includes:
- A concise technical specification of the proposed functionality.
- The rationale behind the feature.
- Implementation details (if applicable).
Authors of EIPs are responsible for building consensus within the community to adopt their proposals.
Types of EIPs
As outlined in the foundational eip-1, EIPs fall into three categories:
1. Standard Track EIPs
These describe changes affecting Ethereum implementations, such as:
- Core: Consensus-critical upgrades (e.g., EIP-5, EIP-101).
- Networking: Improvements to devp2p (EIP-8) or Light Ethereum Subprotocol.
- Interface: API/RPC standards, contract ABIs, or method naming conventions.
- ERC: Application-level standards (e.g., token standards like ERC20).
2. Informational EIPs
These offer general guidelines or highlight design issues without proposing new features.
3. Meta EIPs
Procedural changes to Ethereum’s governance or processes (e.g., eip-1).

ERC: Ethereum Request for Comments
Role in the Ecosystem
ERC (Ethereum Request for Comments) is a subset of Standard Track EIPs focused on application-level standards, such as:
Developers submit ERC proposals via EIPs. Once approved by the Ethereum community, these become official standards, enabling interoperability across dApps.
Why ERC Standards Matter
- Interoperability: Smart contracts following ERC standards (e.g., ERC20) can seamlessly integrate with wallets, exchanges, and other contracts.
- Adoption: Over 80% of Ethereum tokens comply with ERC20, making it the de facto standard for fungible tokens.
FAQs
1. What’s the difference between EIP and ERC?
EIPs are broader proposals for Ethereum improvements, while ERCs specifically address application-level standards under the EIP framework.
2. How does an EIP become an ERC?
An EIP undergoes community review, testing, and final approval by Ethereum’s core developers. If it pertains to token or dApp standards, it’s classified as an ERC.
3. Can ERC standards be updated?
Yes. For example, ERC721 evolved to support non-fungible tokens (NFTs) after iterations.
4. Where can I track active EIP/ERC discussions?
👉 Follow real-time updates on Ethereum proposals.
Conclusion
EIPs and ERCs are the backbone of Ethereum’s decentralized innovation. By standardizing protocols and fostering collaboration, they ensure the ecosystem remains scalable, secure, and developer-friendly.
