The cryptocurrency realm may seem intimidating to the typical investor, particularly those who lack the technical expertise of blockchain technologies. However, the promises among many new digital currencies have enticed all sorts of investors, even individuals who would have been hesitant to participate in a digital token or crypto in the past. The ERC token standard is a significant notion that governs a huge chunk of the space and is especially pertinent to smart contracts & smart property. Let’s discuss more these criteria.

What is an erc token?

ERC tokens are one of the most important Ethereum tokens, and the most often used. It has become clear that ERC tokens are the technical standard that will be utilized for all smart contracts upon that Ethereum network for token implementation, and that they will also establish a set of regulations that will be followed by all Ethereum-based tokens.

ERC stands as “Ethereum request for comment,” and “request for comment” is a similar approach to that created by the Internet Engineering Task Force (IETF) as a way of delivering key technical comments and needs to a group of developers and users.

ERC token standards

An ERC token standard refers to a programming standard which is a technical standard that specifies certain rules and behaviors that an Ethereum token or smart contract must follow.

One of the numerous Ethereum standard tokens focuses on interfaces, which is one of the many Eth development standards. For smart contracts to remain composable, certain requirements must be adhered to for new projects to issue tokens that are interoperable with current decentralized exchanges.

Ethereum Request for Comments (ERC) is a technical document used by Ethereum smart contract developers to interact. They provide a set of rules for deploying tokens in the Ethereum network. These documents, generally prepared by developers, include information on protocol standards and contract specifics. Before an ERC becomes a standard, the community must update, comment, and approve it. This is accomplished via an Ethereum Improvement Proposal (EIP).

Essentially, the Ethereum token standard acts as a guideline for the creation of tokens that are interoperable with the larger Ethereum network. Like most conventional programs, Ethereum, or ether, is a cryptocurrency that enables the development of many applications, including tokens, that do not rely on third-party services to function.

What are the differentiating properties of the ERC token?

In addition, an ERC token has the following characteristics:

Ethereum: ERC-20 tokens are digital assets that are stored on the Ethereum blockchain and may be traded like any other digital asset.

TotalSupply: This is a function that shows the total supply of a certain token throughout a specified period.

balance of: This function displays the number of tokens that a certain address has.

Transfer: A token may be transferred from one user to another

Smart contracts: All token functions are regulated by a network of smart contracts, which ensures that no person or organization can be relied on to ensure that the crypto token operates properly and safely. When certain criteria or circumstances are satisfied, the code is automatically executed. For example, while transferring the token to another party, the user does not have to rely on anybody else to deliver the token to the intended recipient.

How many ERC standard tokens are there?

As of August 2021, there are around 442,647 ERC compliant tokens on Ethereum’s main network, according to CoinMarketCap. The ERC holds significant significance in that it establishes a standard set of rules that all Ethereum tokens must follow to function properly.

ERC token types:

ERC token types

Following are some of the ERC tokens from the ERC token types that we will be discussing.

ERC-20: Since 2015, the ERC-20 standard has dominated Ethereum. Developed by Ethereum, ERC-20 is now the technical standard enabling token deployment on the Ethereum network. It defines a set of rules for all Ethereum-based tokens. On the Ethereum blockchain, ERC-20 tokens can be transferred and received. In contrast to its blockchain, ERC-20 tokens have been distributed over the Ethereum network.

Large-scale issuances of ERC-20 tokens to support new Blockchain enterprises drove the Blockchain boom in 2017 and 2018. For the Blockchain & Ethereum ecosystems, this standard remains relevant in 2020. It has been approved by crypto exchanges and other services.

ERC-725: It is developed by Fabian Vogelsteller, creator of the ERC-20 standard. ERC-725, which describes proxy smart contracts, allows for multiple keys and smart contracts. Identity smart contracts may specify machines, objects, organizations, and people.

Users should be allowed to own and manage their digital identities, not centralized corporations. Security breaches and the unauthorized selling of user data have shown the risks and limitations of a centralized identity. Open identification standards would allow decentralized governance and reputation. Everyone should be able to utilize their identity across applications and platforms.

ERC-223: It warns users who accidentally transfer tokens to a smart contract location and cancels the transfer. Users pay gas fees but will save ETH. Amigocoin is among the few projects currently using ERC-223. It protects customers against fund failures, is fully compatible with the ERC-20 token standard, & runs half as fast as Ethereum.

Although not fully adopted, it does address some of the UX concerns with existing ERC token definitions. Incorrect wallet addresses or worse, smart contracts have resulted in money being lost permanently. While cynical developers may blame end-users for transferring tokens to the incorrect address, this may limit public acceptability.

ERC-777: The ERC-777 virtual token recommends many additional methods to improve blockchain usability, while the ERC-227 solves bugs in the ERC-20 token standard. This digital token adds several additional functionalities to the mainstream ERC-20 token standard. One of the most inventive is the ability to issue or burn tokens, which may be an essential functionality based on a project’s tokenomics model. This ERC token type, more than any other, has the potential to make token transfers significantly simpler.

ERC 1155: It resolves all of the primary difficulties associated with ERC 20 and ERC 721, which were previously considered the best token standards for non-fungible tokens. Users can generate several tokens inside a single contract when using the ERC 1155 protocol. In addition, ERC-1155 may be used for both fungible & non-fungible use cases, depending on the situation. All of these characteristics make ERC1155 more effective at storage management, more efficient, and more cost-effective.

ERC-721: The ERC-721 smart contracts are being utilized by developers all over the globe to construct full virtual worlds, while we’re still in the early phases of broad adoption. Furthermore, NFTs can be utilized in a wide range of sectors, including art, music, fashion, the Internet of Things, and many others, according to the National Institute of Standards and Technology.

When it comes to tokenizing distinct individual items and attributes in collectibles and cryptocurrency games, the ERC-721 standard is now the most extensively utilized. NFT ownership may be transferred and tracked using the basic capabilities of the program.

ERC token list:


As new Eth ERC token standards emerge, each will offer new functionality and bug fixes for current tokens, which will be applied to all existing tokens. To guarantee that your blockchain network gives the most amount of value to end-users, you must first determine which digital token to use. Making sure that the tokenomics of a project, whether it’s an STO or the tokenization of medical information, is correct is a vital step in establishing a successful initiative.
