The Ethereum blockchain has emerged as a leading platform for developing decentralized applications (dApps) and smart contracts. One of the key features enabling this evolution is the variety of token standards available on the Ethereum network. These standards govern how tokens are created, transferred, and managed, allowing developers to build diverse applications—from simple tokens to complex financial instruments. In this article, we’ll explore the primary token standards on Ethereum, their unique characteristics, and their applications in the cryptocurrency ecosystem.
ERC-20 Tokens
The ERC-20 standard is one of the most widely adopted token standards on the Ethereum blockchain. Established in 2015, it defines a set of rules all Ethereum tokens must follow to ensure interoperability with wallets and exchanges.
Key Features:
- Standardized functions and events for seamless integration.
- Easy transfers between users.
- Compatibility with most wallets and exchanges.
- Facilitates dApp creation and ICO fundraising.

ERC-721 Tokens
Unlike ERC-20 tokens, ERC-721 tokens are designed for non-fungible assets, enabling the creation of unique digital items like art, music, and virtual real estate.
Key Features:
- Unique identifiers for each token.
- Verifiable ownership on the blockchain.
- Royalties for creators on secondary sales.
- Widely used in gaming and digital art (NFTs).
ERC-1155 Tokens
The ERC-1155 standard combines fungible and non-fungible tokens in a single contract, reducing complexity and gas costs.
Key Features:
- Multi-token support (fungible and non-fungible).
- Batch transfers for efficiency.
- Enhanced user experience in gaming and collectibles.

ERC-777 Tokens
An advanced evolution of ERC-20, ERC-777 introduces features like data payloads and operator-managed transfers.
Key Features:
- Data-enabled transactions for interactive apps.
- Operator functionality for DeFi innovations.
- Backward-compatible with ERC-20.
ERC-1400 Tokens
Designed for security tokens, ERC-1400 enforces regulatory compliance for real-world asset tokenization (e.g., stocks, real estate).
Key Features:
- Built-in compliance for legal transfers.
- Transparent ownership tracking.
- Institutional-grade security.
Conclusion
Ethereum’s token standards are pivotal in shaping decentralized applications and digital assets. Each standard addresses specific needs, from fungibility (ERC-20) to uniqueness (ERC-721) and hybrid functionality (ERC-1155). As these standards evolve, they’ll drive further innovation across industries like DeFi, gaming, and regulatory-compliant asset tokenization.
FAQ
Q: What’s the difference between ERC-20 and ERC-721?
A: ERC-20 tokens are interchangeable (like currencies), while ERC-721 tokens are unique (like collectibles).
Q: Why use ERC-1155 over ERC-20?
A: ERC-1155 reduces gas fees and supports multiple token types in one contract.
Q: Are ERC-1400 tokens regulated?
A: Yes, they’re designed for compliance with securities laws.
Q: Can ERC-777 replace ERC-20?
A: It enhances ERC-20 with advanced features but remains compatible.
Q: What industries benefit from ERC-721?
A: Art, gaming, and virtual real estate (NFT markets).
Q: How do security tokens use ERC-1400?
A: They tokenize regulated assets (e.g., equity) with embedded legal checks.
