ERC-20 tokens have been the foundation of Ethereum’s blockchain success. They serve as the foundational layer for a global network of decentralized applications (dApps) and cryptocurrencies. For anyone just starting in the blockchain universe, getting acquainted with ERC-20 tokens is a must. Read on as we demystify ERC-20 tokens just for you. It explains their fundamental purpose, benefits and risks in an easy-to-read, simple format. Your Friend of Token, here to help you unlock the mysteries of the Blockchain Trilemma. You’ll dive into scaling solutions, interoperability, and DeFi innovations, with ERC-20 tokens at the center of all three spheres.
Understanding ERC-20 Tokens: What You Need to Know
The ERC-20 standard, more specifically, is a technical blueprint for creating fungible tokens on the Ethereum blockchain. ERC-20 tokens are a standard set of rules to follow. This interoperability standard is pivotal, as it guarantees they can interact smoothly with other applications and wallets across the vibrant Ethereum ecosystem. Consider it a bridge language that helps all tokens to seamlessly interact and coordinate.
The ERC-20 standard specifies the mechanics of these tokens, including transferring, approving transactions, and accessing data. The Ethereum community developed these ERCs with three optional guidelines and six required. This level of standardization is what makes ERC-20 tokens so powerful and versatile.
Definition and Purpose of ERC-20 Tokens
ERC-20 is short for “Ethereum Request for Comments 20.” It’s a technical standard that provides developers with the tools to create fungible tokens on the Ethereum blockchain. Fungible simply means that each token is worth the same as another; like one dollar is equal to another dollar. These tokens can be used to represent everything from real-world assets and loyalty points to in-game currencies and on-chain governance votes.
Although ERC-20 created by Fabian Vogelsteller and Vitalik Buterin was created in 2015, it was formally adopted only in 2017. ERC-20 tokens have an important function in the ecosystem. They provide developers with a standard and interoperable way to create and manage tokens on the Ethereum blockchain. This uniformity makes for convenient, plug-and-play integration with exchanges, wallets, and other dApps, creating a bustling and interrelated environment.
Key Features of ERC-20 Tokens
The ERC-20 standard specifies six required functions and three optional functions. These functions define how tokens are transferred. In addition, they control the supply and dictate ways in which users can interact with the tokens. Here's a breakdown:
ERC-20 tokens are directly applicable and compatible with a wide variety of products and services, including pretty much all dApps developed on the Ethereum blockchain. These functions are what make all ERC-20 tokens predictable, reliable, and easy to integrate into other platforms and applications.
totalSupply()
: Returns the total number of tokens in circulation.balanceOf(address tokenOwner)
: Returns the number of tokens owned by a specific address.transfer(address receiver, uint numTokens)
: Transfers a specified number of tokens from the sender's address to the receiver's address.approve(address delegate, uint numTokens)
: Allows a spender to withdraw a certain number of tokens from your account.allowance(address tokenOwner, address delegate)
: Returns the number of tokens that a spender is still allowed to withdraw from an owner.transferFrom(address owner, address buyer, uint numTokens)
: Transfers tokens from one address to another, but requires prior approval using theapprove
function.
If you’re looking to develop your own ERC-20 token, you will be faced with a number of development scenarios. Each approach comes with its own set of benefits and drawbacks. Your ideal option depends on your level of technical expertise, how much you can spend, and what your individual project requires. Let's explore three common approaches: DIY development, hiring an agency, and utilizing no-code tools.
name()
: Returns the name of the token (e.g., "MyToken").symbol()
: Returns the symbol of the token (e.g., "MTK").decimals()
: Returns the number of decimals the token uses (e.g., 18, which is common).
Creating your own ERC-20 token from the ground up offers the most flexibility and control during the development process. By the end, you’ll know how to customize every aspect of the token to your whims! This method requires a strong understanding of smart contract programming.
