Key Takeaways

• The ERC-20 is a token standard on the Ethereum blockchain. It is a rulebook for making digital tokens.

• The ERC-20 token standard was introduced in 2017 by developer Fabian Vogelsteller.

• ERC-20 tokens are fungible tokens which function by following specific rules for compatibility with Ethereum.

In July 2015, Vitalik Buterin, Gavin Wood and a host of other blockchain developers launched the Ethereum (ETH) blockchain which was a more flexible alternative to the Bitcoin (BTC) blockchain. The Bitcoin blockchain was exclusively designed as a digital ledger book for recording cryptocurrency transactions within its network.

Ethereum, on the other hand, was the first open-source platform which could allow developers and creators to build decentralised applications (dApps), create smart contracts and launch various tokens on its blockchain. However, before 2017, tokens created on the Ethereum blockchain like ETH lacked fungibility and interchangeability. This led developers in the Ethereum community to create a token standard for all tokens minted on the Ethereum blockchain with the help of smart contracts.

The token standard was called the Ethereum Request for Comment 20 (ERC-20) standard. With the creation of this standard, tokens minted on the Ethereum blockchain followed a set of guidelines, thereby facilitating the work of developers building on the blockchain.

Today the ERC-20 token standard has become the normal token standard for the creation of any token on the Ethereum blockchain. In this article, we will discuss everything you should know about ERC-20 tokens, including what they are, the most traded ERC-20 tokens, and their use cases.

What is the ERC-20 Token Standard?

The ERC-20 token standard is a rulebook for making digital tokens on the Ethereum blockchain. It guides developers in creating tokens that work smoothly with other tokens and programs built on the Ethereum blockchain. This token standard ensures consistency and interchangeability, making all tokens compatible for seamless interaction on the blockchain.

This standard simplifies token creation and usage, enabling tokens to be used in various applications. ERC-20 tokens are fungible tokens which function by following specific rules for compatibility with Ethereum. These rules, which are embedded within a token's smart contract, dictate factors like quantity and transferability.

Transactions involving ERC-20 tokens are recorded on the Ethereum blockchain, ensuring transparency in ownership. These tokens have diverse applications, such as representing assets and facilitating payments within decentralized applications.

Creation of ERC-20  

The ERC-20 token standard, introduced in 2017 by developer Fabian Vogelsteller, emerged as a necessity within the Ethereum community. Facing the challenge of fragmented token creation methods, Vogelsteller proposed a set of rules aimed at simplifying the process and enhancing token interoperability.

Through collaborative discussions within the Ethereum community, these rules underwent refinement, ultimately culminating in their approval as an Ethereum Improvement Proposal (EIP). This collective effort resulted in a standardised framework that not only facilitates streamlined token creation, but also fosters greater compatibility and cohesion across the Ethereum network.

Image: Use Cases Of ERC-20 Tokens

ERC-20 token standards serve various purposes in the blockchain and cryptocurrency space. Here are a few examples:

Utility Tokens

The primary use case of the ERC-20 tokens is for utility. ERC tokens are designed as tokens that can be used for payments within specific blockchain projects. For instance, users could spend ERC-20 tokens to buy storage space in a decentralised file storage system.

Cross-border Payments for Goods and Services

Businesses can issue their own ERC-20 tokens for customers to use in purchasing products or services. Examples of tokens with this ability are the USDT and USDC. These ERC 20 stablecoins have monetary value and can be used as a means of payment or exchanged for fiat currencies. ERC-20 tokens facilitate quick cross-border payments without traditional banking systems.

Loyalty Rewards and Reputation Points

Online platforms can issue ERC-20 tokens as loyalty rewards or reputation points, which users can use for future bookings or trade with others.

Tokenisation of real-world assets (RWAs)

Companies can issue ERC-20 tokens which represent RWAs like gold or real estate. For example, Tether Gold (XAUT) is an ERC-20 token that represents a portion of physical gold and this is issued by Tether. Each XAUT token is pegged to physical gold, and holders of this token can redeem their tokens for physical gold, but this is subject to a minimum redemption amount.

Fundraising for projects

Blockchain projects raise funds through Initial Coin Offerings (ICOs) by selling ERC-20 tokens to investors.

Benefits of ERC-20

The ERC-20 token standard is crucial in crypto for several reasons:

Simplicity & Accessibility

Alongside simplifying token creation, ERC-20 enhances the accessibility of cryptocurrency trading. Its standardised format streamlines the development process for developers, reducing the entry barrier for launching new cryptocurrencies and digital assets on the Ethereum platform. This simplicity extends to users, making cryptocurrency trading more accessible for both beginners and experienced traders. By offering a consistent and familiar framework, ERC-20 contributes to a user-friendly experience for individuals engaging with Ethereum-based tokens.

Transparency & Trust

The ERC-20 standard ensures transparent token creation, allowing interested parties to examine token properties easily. This transparency builds trust in the system, as users can verify token integrity before engagement. By standardising token creation, ERC-20 promotes consistency, enhancing trust among Ethereum ecosystem participants.

Network Effect

ERC-20 tokens drive a significant network effect within the Ethereum community. Enabling easy token creation, ERC-20 fuels decentralised application (DApp) development on the Ethereum blockchain. This surge in developer activity creates a vibrant ecosystem, attracting users and investors. The 2017 ICO boom, propelled by ERC-20 tokens, saw numerous projects emerge, boosting Ethereum network growth.
