The ERC-20 token standard is a rulebook for making digital tokens on the Ethereum blockchain. This token standard ensures consistency and interchangeability, making all tokens compatible for seamless interaction on the blockchain.
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.
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.
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:
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.
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.
Online platforms can issue ERC-20 tokens as loyalty rewards or reputation points, which users can use for future bookings or trade with others.
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.
Blockchain projects raise funds through Initial Coin Offerings (ICOs) by selling ERC-20 tokens to investors.
The ERC-20 token standard is crucial in crypto for several reasons:
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.
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.
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.
ERC-20 tokens boast compatibility with various third-party services like exchanges and wallets. This interoperability enables easy token trading, storage, and management across platforms. Users can seamlessly transfer ERC-20 tokens between wallets or exchange them on multiple exchanges without compatibility issues. This broad compatibility enhances ERC-20 token liquidity and accessibility, fostering widespread adoption in the cryptocurrency ecosystem.
ERC-20's standardised token creation minimises errors and vulnerabilities in Ethereum smart contracts. Clear guidelines and best practices mitigate smart contract bugs and security breaches. Developers can rely on established standards when creating ERC-20 tokens, reducing risks associated with token deployment. This risk reduction instils confidence among users and investors, driving wider ERC-20 token adoption in the Ethereum ecosystem.
ERC-20 tokens are designed for seamless integration into platforms like exchanges and wallets. This simplicity is vital for developers integrating new tokens. By adhering to a standard format, ERC-20 tokens can effortlessly integrate with diverse platforms, enabling efficient token management. This straightforward integration accelerates new token adoption and enhances the functionality of decentralised exchanges and crypto wallets, ensuring a smooth user experience.
The drawbacks of ERC-20 token standard are:
Due to the standardised nature of ERC-20 tokens, it is not possible to customise them as per different requirements. Gaming and multimedia companies therefore find ERC-20 disadvantageous.
Being Ethereum-based, ERC-20 tokens are vulnerable to the same kinds of security risks such as cyber-attacks, hacks, or exploits.
The governance model of the ERC-20 is not very transparent, making it susceptible to risks such as token dumping, or insider trading.
Trading in ERC-20 tokens can incur high costs due to volatile gas fees. This is common to all Ethereum transactions even as EIP-1559 has tried to stabilise the gas fees.
ERC-20 wallets are digital tools tailored for handling Ethereum-compatible tokens, including those adhering to the ERC-20 standard. They operate just like the standard crypto wallets, facilitating the storage, transmission, and reception of ERC-20 tokens.
These wallets are compatible with most Ethereum wallets, enabling the transfer of tokens to any Ethereum wallet address, and offering users a broad selection. They come in various forms such as hardware, web-based, and mobile wallet. Popular ERC-20 wallets include the BitDelta wallet, MetaMask, Ledger Nano X, etc.
