Blockchain development has revolutionized business operations. While cryptocurrency coins serve as key investment assets, tokens play an equally vital role. This guide explores tokens, tokenization, Ethereum's ERC standards, and their applications.
What Are Tokens?
Tokens, or crypto tokens, are units of value built atop existing blockchain networks. Unlike cryptocurrencies (native to their blockchains), tokens rely on parent blockchains like Ethereum. Examples include:
- LINK (Chainlink)
- COMP (Compound)
- DAI (MakerDAO)

What Is Tokenization?
Tokenization converts assets or ownership rights into digital tokens. It enables:
- Fractional ownership of physical assets (e.g., real estate)
- Enhanced security by replacing sensitive data with non-sensitive tokens
- Liquidity for traditionally illiquid assets
Ethereum's ERC Framework
ERC (Ethereum Request for Comments) documents propose technical standards for Ethereum improvements. These community-reviewed guidelines ensure interoperability across tokens and smart contracts.
Key ERC Token Standards
ERC-20: The Fungible Token Standard
Characteristics:
- Uniform value (1 ETH = 1 ETH)
- Used for stablecoins (USDT, USDC), ICOs, and governance tokens
- Enables seamless exchange via smart contracts
Example Use Case:
Uniswap's UNI token facilitates decentralized exchange liquidity.
ERC-721: Non-Fungible Tokens (NFTs)
Characteristics:
- Unique digital assets (e.g., CryptoKitties)
- Indivisible and non-interchangeable
- Powers digital art, collectibles, and gaming items
Example Use Case:
Bored Ape Yacht Club NFTs represent exclusive digital artwork.
ERC-1155: Multi-Token Standard
Characteristics:
- Combines fungible and non-fungible tokens in one contract
- Reduces gas fees by batching transactions
- Ideal for gaming (e.g., in-game currencies + unique items)
Example Use Case:
Enjin's blockchain games use ERC-1155 for both currency and virtual land.
Comparing ERC Standards
| Feature | ERC-20 | ERC-721 | ERC-1155 |
|---|---|---|---|
| Fungibility | Yes | No | Both |
| Use Cases | ICOs | NFTs | Gaming |
| Gas Efficiency | Medium | Low | High |
The Future of Token Standards
Emerging standards like ERC-4626 (tokenized vaults) address DeFi needs, highlighting Ethereum's adaptability.
FAQs
1. Can ERC-20 tokens become NFTs?
No. ERC-20 tokens are inherently fungible. For NFTs, use ERC-721 or ERC-1155 (non-fungible mode).
2. Why choose ERC-1155 over ERC-20/721?
ERC-1155 offers:
- Lower transaction costs
- Mixed token types in one contract
- Better scalability
3. Are tokens safer than cryptocurrencies?
Security depends on:
- Smart contract audits
- Blockchain robustness
- Private key management
4. How do I create an Ethereum token?
Steps:
- Learn Solidity
- Choose a standard (ERC-20/721/1155)
- Deploy via Remix IDE or Truffle
Final Thoughts
Ethereum's token standards enable diverse blockchain applications—from DeFi to digital art. As Web3 evolves, expect more specialized standards to emerge.
