ERC token standards are a set of technical rules on the Ethereum blockchain that define how tokens behave and interact with smart contracts, wallets, and decentralized apps (dApps). These standards ensure that tokens are compatible across the network, making it easier for developers to build and deploy them.

By following ERC standards, projects can create tokens that work seamlessly within the Ethereum ecosystem, enabling efficient token transfers, ownership tracking, and much more. Let’s explore the top ERC token standards shaping the blockchain landscape today.

An Overview of ERC Token Standards

ERC, short for Ethereum Request for Comments, is the blueprint developers follow to ensure tokens “speak the same language” as the rest of the Ethereum system.

This way, tokens can easily interact with dApps, wallets, and other tools. By sticking to ERC standards, developers can launch tokens that plug right into the Ethereum framework, avoiding any compatibility headaches.

These standards come from community-driven proposals called Ethereum Improvement Proposals (EIPs). Developers suggest improvements or fixes to the network, and once approved, they become official guidelines that anyone building on Ethereum can use. It’s a collaborative process that keeps the system flexible and innovative while maintaining consistency.

Interoperability is key here — it allows tokens and apps to interact seamlessly. As Ethereum continues to evolve, with upgrades like the Ethereum Pectra Upgrade bringing in more advanced features, ERC standards ensure that everything still works together smoothly.

Top ERC Token Standards List

ERC token standards are vital in defining how different types of tokens operate within the Ethereum ecosystem.

In this section, we’ll explore the top ERC token standards, explaining their significance and use cases.

ERC-20: Fungible Token Standard

The ERC-20 standard is the backbone of most fungible tokens on the Ethereum network. Fungibility refers to identical and interchangeable tokens, making them perfect for assets like stablecoins and utility tokens.

Key functionalities of ERC-20 include:

• totalSupply: It defines the total amount of tokens created.
• balanceOf: It shows the balance of tokens for any given address.
• Transfer: It enables users to send tokens to another address
• The combination of approve and allowance allows you to approve spending by another account.

The ERC-20 token standard is the most widely used in the Ethereum ecosystem, and popular tokens like USDT and Chainlink have adopted it.

ERC-721: Non-Fungible Token (NFT) Standard

ERC-721 is the go-to standard for creating non-fungible tokens (NFTs), which are unique digital assets that another token cannot replace. Unlike ERC-20, each ERC-721 token is distinct, making them ideal for use cases like digital art, collectibles, and gaming items.

Key functionalities include:

• Minting: It’s the process of creating new tokens like digital artwork or collectibles.
• Transferring: It enables the transfer of ownership from one address to another.
• Metadata: It stores additional details about the token, such as its name, description, and traits.

Notable examples of ERC-721 tokens include CryptoPunks and Bored Apes, which have made waves in the digital collectibles space. If you’re interested in NFT minting, ERC-721 is the standard to follow.

ERC-1155: Multi-Token Standard

ERC-1155 introduces a versatile standard supporting fungible and non-fungible tokens in a single contract. This flexibility makes it particularly useful for blockchain gaming, where assets can range from in-game currencies (fungible) to unique items like weapons or skins (non-fungible).

One of the standout features of ERC-1155 is its ability to perform batch transfers, allowing multiple tokens to be sent in a single transaction. This feature reduces transaction costs and boosts efficiency, especially in high-volume scenarios like blockchain games.

A notable project using ERC-1155 is Enjin, which focuses on in-game assets and collectibles.

Comparisons Between Key ERC Token Standards

Now, we’ll dive into the differences between the major ERC token standards, highlighting how they work, their features, and where they fit in the Ethereum ecosystem. Each comparison comes with practical examples to show how these standards serve unique purposes.

ERC-20 vs. ERC-721: Fungible vs. Non-Fungible Tokens

ERC-20 and ERC-721 tokens differ significantly in their purpose. While the ERC-20 token standard is used to create fungible tokens like cryptocurrencies, ERC-721 is designed for non-fungible tokens (NFTs), where each token is unique.

ERC-20 tokens are divisible, making them ideal for everyday transactions, while ERC-721 tokens represent one-of-a-kind assets, often used for digital art or collectibles.

ERC-721 vs. ERC-1155: Non-Fungible vs. Multi-Tokens

ERC-721 is perfect for one-of-a-kind assets like digital art because it only supports NFTs and focuses on individual transfers.

On the flip side, ERC-1155 handles both fungible and non-fungible tokens, and its real strength is batch transfers, making it super efficient for gaming crypto coins and in-game assets.

ERC-20 vs. ERC-1155: Fungible vs. Multi-Tokens

ERC-20 focuses on fungible tokens with a single contract handling one token type, while ERC-1155 supports multi-token contracts, managing both fungible and non-fungible tokens. This leads to greater gas efficiency and batch transfer capabilities in ERC-1155, reducing the cost per transaction compared to smart contract operations in ERC-20.

Choosing the Right ERC Token Standard for Your Project

Picking the right ERC token standard can feel like a big decision, but it’s really about understanding your project’s needs. Each standard has its strengths, so let’s dive into when to use each one and why it matters.

When to use ERC-20:

ERC-20 is perfect if you’re creating fungible tokens — basically, tokens that are all the same and can be easily swapped with one another. Think of cryptocurrencies like stablecoins or governance tokens.

If your project involves currency or utility tokens that users will trade or use in a decentralized app (dApp), ERC-20 is your best bet. It’s a tried-and-true standard for creating the backbone of many tokens and coins.

When to use ERC-721:

ERC-721 is your go-to if you’re dealing with unique items like digital art, collectibles, or anything where no two tokens are alike. Each token has its own value and properties, which is why it’s the foundation of the NFT world.

If you’re creating a project with rare assets, like limited-edition items or one-of-a-kind collectibles, ERC-721 ensures each item is distinct and non-fungible.

When to use ERC-1155:

ERC-1155 is like the best of both worlds. It’s great for projects that need both fungible and non-fungible tokens, making it ideal for gaming platforms or anything with a complex asset system.

If your project involves many in-game items, some unique and others common, ERC-1155 offers efficient batch transfers, which saves time and gas fees. For game developers or projects juggling multiple asset types, this is the standard that can handle it all.

Understanding Lesser-Known ERC Standards

While ERC-20 and ERC-721 steal the spotlight, several lesser-known ERC standards provide solutions for specific use cases. These standards may not be as mainstream, but they enhance functionality across the Ethereum network.

ERC-777: Operator-Based Token Standard

ERC-777 brings a fresh twist to token transfers by allowing third parties, or operators, to manage transactions on behalf of users.

This is especially useful in scenarios like subscription services or batch transfers. It’s backward-compatible with ERC-20 but offers more advanced functionality, including hooks that boost cryptocurrency security by preventing accidental transfers.

ERC-998: Composable Non-Fungible Tokens

ERC-998 takes NFTs to the next level by introducing the ability for tokens to own other tokens. Whether you want your NFT to hold another NFT or a fungible token, this standard makes that possible.

It’s perfect for asset bundling or creating hierarchies within digital collectibles — think of it as building a digital empire where one NFT can hold many others.

ERC-4626: Yield-Bearing Vaults Standard

ERC-4626 focuses on yield-generating assets and provides a framework for tokenized vaults in DeFi applications. It streamlines how assets are staked or lent, making the process more efficient.

Whether you’re into cryptocurrency lending, staking, or yield farming, ERC-4626 is the go-to standard. Its focus on vaults makes it a natural fit for DeFi apps that need to manage yield-bearing assets effectively.

ERC-223: Secure Token Transfers

The ERC-223 standard aims to reduce user error by preventing the accidental sending of tokens to incompatible contracts. The TokenFallback feature ensures that transactions only occur if the destination contract can handle the token, adding an extra layer of security to cryptocurrency transfers.

ERC-827: Enhanced Transaction Data

ERC-827 builds upon ERC-20 by allowing transactions to carry additional data, making it more versatile. This standard also simplifies processes by combining approval and transfer into a single transaction, making it more efficient for users.

ERC-864: Shared NFT Ownership

ERC-864 introduces the concept of shared ownership for NFTs, which could transform how digital assets are co-owned. This standard opens up new opportunities for fractional ownership, whether for a piece of digital art or tokenized real estate.

ERC-865: Pre-Signed Token Transfer

This standard allows token transfers to happen without the sender paying gas fees upfront. The transaction is pre-signed by the sender, reducing the cost and complexity of frequent transfers.

For users concerned about Ethereum gas fees, ERC-865 provides a practical alternative.

ERC-1132: Token Locking Capability

ERC-1132 introduces the ability to time-lock tokens within smart contracts, making it a useful standard for managing token vesting schedules or lock-up periods for investors. This ensures that tokens can’t be accessed before a specific time, providing additional security for long-term projects.

ERC-1203: Multi-Class Token Standard

Finally, ERC-1203 supports multiple classes of fungible tokens within a single contract, making it ideal for use in multi-layered token ecosystems. This flexible structure can benefit loyalty programs, reward systems, or multi-tier token systems.

The Future of ERC Token Standards

The evolution of ERC token standards is far from over. As Ethereum continues to grow, we’re seeing a shift towards more experimental and advanced standards that aim to tackle new challenges in the blockchain space.

These experimental standards are designed to solve niche problems or add specialized features. While not all of them will be widely adopted, they push the envelope on what Ethereum can do.

Here’s a quick rundown of a few you should keep an eye on:

• ERC-404 token standard: It enables fractional ownership of NFTs by merging the features of fungible ERC-20 tokens with non-fungible ERC-721 tokens, enhancing liquidity in the NFT market.
• DN-404: It separates the functions of ERC-20 and ERC-721 into distinct contracts, simplifying smart contract management and improving compatibility for divisible NFTs.
• ERC-1337: A proposal for handling recurring payments on the Ethereum blockchain, streamlining subscriptions, and automatic transfers.

Looking ahead, ERC token standards are expected to see even greater adoption in sectors like DeFi, NFTs, and blockchain gaming. Developers are working on optimizing gas efficiency and enhancing cross-chain interoperability, ensuring that ERC tokens can thrive in an increasingly interconnected blockchain ecosystem.

Final Thoughts on ERC Token Standards

ERC token standards form the backbone of Ethereum’s versatility, driving innovation across various sectors such as DeFi, NFTs, and beyond. As new standards emerge, they will continue to shape how developers create secure, scalable, and interoperable decentralized applications.

For those looking to deepen their knowledge of Ethereum, understanding the proof-of-stake (PoS) consensus mechanism is essential to see how the network secures transactions and incentivizes token holders.
