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 enabling standardized token creation, transfers, and approval mechanisms across the 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.
- • ERC-4337: Account abstraction enabling advanced transaction management with smart contracts as account abstractions.
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 and transfers across the Ethereum blockchain.
ERC-721
Non-fungible token (NFT) standard ensuring unique token ownership for digital collectibles assets.
ERC-1155
Multi-token standard combining fungible and non-fungible properties for bulk operations.
ERC-4337
Account abstraction standard allowing smart contracts to function as wallets.
Technical Implementation Analysis
Ethereum standards are implemented through smart contract interfaces with:
- • Standardized function signatures: e.g.,
transferFrom(),approve() - • Event definitions: for contract interactions and metadata
- • 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.
