What are ERC Tokens?
ERC, or Ethereum Request for Comments, is a protocol that defines certain rules and standards in the Ethereum ecosystem. ERC tokens are digital assets that adhere to these standards and exist on the Ethereum blockchain. They have become a fundamental part of the Ethereum network, enabling developers to predict how new tokens will function within the system. This interoperability has led to an explosion in the number of tokens and decentralized applications (dApps) on the Ethereum network.
The Different Types of ERC Token Standards
ERC tokens come in various types, each with its unique features and use cases. Here are some of the most popular token standards on Ethereum:
ERC-20
ERC-20 is the standard for fungible tokens, meaning each token is identical to every other token; it’s interchangeable like cash or Bitcoin. This standard has been adopted by many ICOs (Initial Coin Offerings), and it’s supported by most wallets and exchanges.
ERC-721
ERC-721 is the standard for non-fungible tokens (NFTs), meaning each token has unique properties and value. This standard has given rise to digital collectibles like CryptoKitties, where each digital cat is unique.
ERC-777
ERC-777 is a more advanced token standard that allows people to build extra functionality on top of tokens such as a mixer contract for improved transaction privacy or an emergency recover function to bail you out if you lose your private keys.
ERC-1155
ERC-1155 is a more complex standard that can represent any number of fungible and non-fungible tokens. It’s especially useful in gaming platforms, where a user might own a multitude of different items, each with different properties.
ERC-4626
ERC-4626 is a tokenized vault standard designed to optimize and unify the technical parameters of yield-bearing vaults.
ERC-6551
ERC-6551 is a new standard that allows you to turn any of your NFTs into a crypto wallet.
This NFT wallet will function like a regular wallet, where you can store tokens and other NFTs, as well as interact with DeFi applications, participate in voting, and even own domains.

How ERC Tokens Work
ERC tokens function within the Ethereum network through the use of smart contracts. A smart contract is a self-executing contract with the terms of the agreement directly written into code. The code and the agreements contained therein exist across a distributed, decentralized blockchain network.
When a token is created on the Ethereum network, it is governed by a smart contract. This contract includes a set of rules and functions that define how the token behaves – how it can be transferred, how transactions are approved, how users can access data about the token, and more.
Let’s break down the process:
Token Creation
When a new ERC token is created, a smart contract is deployed on the Ethereum blockchain. This contract includes a set of rules and functions specific to the token, such as the total supply of the token, the process for transferring the token, and the mechanism for retrieving the total balance of tokens from a given account.
Token Interaction
Once the token is created, users can interact with it through the functions defined in the smart contract. For instance, a user could transfer tokens from their account to another account, or they could approve another user to withdraw tokens from their account. All of these interactions are governed by the rules set out in the smart contract.
Ethereum Token Standards
The different ERC standards (like ERC-20, ERC-721, etc.) define a common list of rules and functions that a token’s smart contract must implement. This standardization allows different tokens to interact in a predictable way, and it allows developers to build applications that can interact with any token, regardless of its specific implementation.
For example, a digital wallet application could be built to support any ERC-20 token, because every ERC-20 token’s smart contract includes a common set of functions like transfer, balanceOf, and approve. The wallet application just needs to call these functions to interact with the token, without needing to know the specific details of how the token is implemented.
Did You Know?
Interesting fact: Any user can create their own token standard and present it on the developers’ forum. If it gets approved, it will be implemented in future Ethereum updates. This open-source approach fosters innovation and allows for the continuous evolution of the Ethereum ecosystem.
The Impact of ERC Tokens on the Crypto Industry
ERC tokens have had a profound impact on the crypto industry, shaping the way we interact with blockchain technology and paving the way for a host of innovative applications.
Standardization
One of the most significant impacts of ERC tokens is the standardization they bring to the Ethereum blockchain. Before the introduction of ERC standards, developers creating new tokens on the Ethereum network had to write their own implementations of these functions. This lack of standardization made it difficult for different tokens to interact with each other and for developers to create applications that could interact with multiple tokens.
ERC standards have solved this problem by defining a common set of rules and functions that all tokens must adhere to. This standardization has made it easier for developers to create new tokens and for these tokens to interact with each other and with other applications on the Ethereum network.
Innovation
ERC tokens have also spurred innovation in the crypto industry. The introduction of ERC-20 led to an explosion in the number of tokens on the Ethereum network, as it became much easier for developers to create new tokens. This, in turn, led to the Initial Coin Offering (ICO) boom of 2017, where billions of dollars were raised for new projects.
The introduction of ERC-721 and ERC-1155 has opened up new possibilities for tokenization, leading to the creation of non-fungible tokens (NFTs) and the rise of digital art, collectibles, and virtual real estate.
DeFi and Beyond
ERC tokens have also played a crucial role in the rise of decentralized finance (DeFi). Many DeFi applications are built on the Ethereum network and use ERC-20 tokens. These applications provide services like lending, borrowing, and trading, all in a decentralized manner.
Moreover, ERC tokens have enabled the creation of decentralized autonomous organizations (DAOs), where ERC-20 tokens are often used for governance. Token holders can vote on proposals based on the number of tokens they hold.
Future of ERC Tokens
As we look ahead, the future of ERC tokens appears to be bright and promising. The continuous evolution of blockchain technology and the ever-growing adoption of cryptocurrencies suggest that ERC tokens will continue to play a significant role in the crypto space. Here are a few potential directions for the future of ERC tokens:
