ERC tokens are digital assets built on the Ethereum (ETH) blockchain, following standardized protocols to ensure interoperability. These standards, known as Ethereum Request for Comments (ERC), enable seamless interaction between tokens that would otherwise lack compatibility.
This article explores major ERC standards (including ERC20 and ERC223), highlights popular ERC-based cryptocurrencies, and examines the future potential of ERC protocols.
Understanding ERC Tokens
ERC tokens are blockchain-based assets that adhere to specific technical guidelines proposed through Ethereum Improvement Proposals (EIPs). The most widely adopted standard, ERC20, emerged from these proposals and now underpins countless cryptocurrencies.
Key points:
- ERC20: The foundational standard for fungible tokens (e.g., cryptocurrencies).
- ERC223: An upgrade addressing ERC20’s issue of irrecoverable mistaken transfers.
- ERC721: The standard for non-fungible tokens (NFTs), enabling unique digital assets.

Major ERC Standards Explained
1. ERC20
- Purpose: Facilitates fungible tokens (interchangeable assets like currencies).
- Use Case: Cryptocurrencies such as DAI and BAT.
2. ERC223
- Improvement: Prevents token loss from accidental transfers by reverting transactions to the sender.
3. ERC721
- Purpose: Manages non-fungible tokens (NFTs), like digital art or collectibles.
4. ERC725/735
- Focus: Decentralized identity (DID) management, enhancing privacy and reducing reliance on centralized systems.
5. ERC1155
- Innovation: Supports both fungible and non-fungible assets (e.g., in-game currencies and items).
Popular ERC-Based Cryptocurrencies
| Token | Use Case | Example Platform |
|-------------|-----------------------------------|------------------------|
| BAT | Rewards for ad engagement (Brave browser) | Coincheck |
| DAI | USD-pegged stablecoin | GMO Coin |
| MATIC | Scalability solution for Ethereum | Bitbank |
How to Buy ERC Tokens
Choose a Regulated Exchange:
- Japan-based platforms like GMO Coin (BAT, DAI) or Bitbank (MATIC) offer secure purchasing options.
- Avoid Unlicensed Platforms: Stick to Financial Services Agency (FSA)-approved exchanges for compliance.
The Future of ERC Standards
ERC protocols continue to evolve, enabling:
- Enhanced Security: Decentralized ID management (ERC725).
- Broader Utility: Hybrid tokens (ERC1155) for gaming and DeFi.

FAQ
Q1: What’s the difference between ERC20 and ERC721?
- ERC20: For interchangeable tokens (e.g., currencies).
- ERC721: For unique assets (e.g., NFTs).
Q2: Can ERC223 tokens be recovered if sent incorrectly?
- Yes, unlike ERC20, ERC223 reverts mistaken transfers.
Q3: Where can I buy MATIC tokens?
- Licensed exchanges like Bitbank support MATIC trading.
Final Thought: ERC standards are pivotal to blockchain’s expansion, from finance to digital identity. Their ongoing development will likely unlock new decentralized applications, making them a cornerstone of Web3.
