ERC XXXX Standards

ERC (Ethereum Request for Comments) refers to technical standards used to define how smart contracts and tokens operate on the Ethereum blockchain. Each ERC proposal includes a unique number (like ERC-20, ERC-721, ERC-1155, etc.), which identifies a specific token or functionality standard.

ERC standards ensure interoperability, consistency, and security across decentralized applications (dApps). They allow developers to create tokens, NFTs, and smart contracts that can easily interact with wallets, exchanges, and DeFi platforms.

Some of the most well-known ERC standards include:

💠 ERC-20 — Defines fungible tokens (like cryptocurrencies or utility tokens).

🖼️ ERC-721 — Defines non-fungible tokens (NFTs) with unique identities.

⚙️ ERC-1155 — Supports both fungible and non-fungible tokens in one contract (used in gaming).

🔐 ERC-777, ERC-4626, ERC-6551, etc. — Introduce advanced features like token security, vaults, and token-bound accounts.

Each new ERC proposal starts as an EIP (Ethereum Improvement Proposal) and, if approved, becomes an official ERC standard — shaping how Ethereum evolves.
In short, ERC standards are the “rules of the Ethereum world”, ensuring that innovation remains compatible, secure, and decentralized.
