Overview of Ethereum Standards
Ethereum's token standards form the backbone of modern blockchain ecosystems. This article explores the technical foundations of:
- • ERC-20: Standard interface for fungible tokens
- • ERC-721: Non-fungible token (NFT) implementation
- • ERC-1155: Multi-token standard combining fungible and non-fungible properties
- • Experimental standards like ERC-4337 (account abstraction)
Through analysis of solidity implementations and network interactions, we uncover how these standards enable complex decentralized applications while maintaining protocol consistency.
Standard Implementations
ERC-20
Fungible token standard enabling standardized token creation, transfers, and approval mechanisms across Ethereum blockchain.
ERC-721
Non-fungible token (NFT) standard providing unique token ownership proofs for digital art, collectibles and gaming assets.
ERC-1155
Multi-token standard combining fungible and non-fungible properties for efficient bulk token operations.
Technical Implementation Analysis
Ethereum standards are implemented through smart contract interfaces with:
- • Standardized function signatures (e.g., transferFrom(), approve())
- • Event definitions for contract interactions
- • ABI encoding compatibility between tokens and DApps
- • Gas optimization patterns for frequent operations
Developers can use frameworks like Hardhat to verify smart contracts against these standards and deploy standardized tokens across the Ethereum network.
