Key Takeaways
- Token standards define how tokens behave and interact with other contracts
- Different standards suit different asset types and use cases
- Standards enable interoperability across platforms and wallets
Token standards are the building blocks of the digital asset ecosystem. They define how tokens function, how they interact with wallets and exchanges, and what rights they confer to holders. Understanding these standards is essential for anyone involved in tokenization.
Over 500,000 ERC-20 tokens have been deployed on Ethereum alone, making it the most widely adopted token standard in history.
ERC-20: Fungible Tokens
ERC-20 is the most common token standard on Ethereum. It defines fungible tokens—tokens that are identical and interchangeable. ERC-20 tokens are ideal for currencies, utility tokens, and securities where each share is identical.
"Token standards are the common language of digital assets — without them, interoperability would be impossible."
ERC-721: Non-Fungible Tokens (NFTs)
ERC-721 defines non-fungible tokens, where each token is unique. NFTs are used for digital art, collectibles, and real estate where each asset has distinct properties.
ERC-1155: Multi-Token Standard
ERC-1155 allows a single contract to manage multiple token types, both fungible and non-fungible. This efficiency reduces gas costs and simplifies portfolio management.
Migrating tokens between standards after deployment is complex and costly. Select the right standard during the design phase to avoid expensive restructuring later.
ERC-4626: Tokenized Vaults
ERC-4626 standardizes tokenized vaults that represent shares in a pool of assets. This standard is gaining traction for yield-bearing tokens and fund structures.
| Standard | Token Type | Best Use Case |
|---|---|---|
| ERC-20 | Fungible | Currencies, securities, utilities |
| ERC-721 | Non-Fungible | Real estate, art, collectibles |
| ERC-1155 | Multi-Token | Gaming, mixed portfolios |
| ERC-4626 | Tokenized Vault | Yield-bearing pools, funds |
Security Token Standards
Security tokens often use specialized standards like ERC-1400 or ERC-3643 that include compliance features such as investor verification and transfer restrictions.

Frequently Asked Questions
Which token standard should I use?
The choice depends on your asset type. Fungible assets like stocks use ERC-20, unique assets like real estate use ERC-721, and security tokens may require specialized standards.
Can tokens be upgraded to new standards?
Tokens can sometimes be migrated to new standards through token swaps, though this requires careful planning and investor communication.
