It is a standard for creating interoperable tokens on the Ethereum Virtual Machine. If a Smart Contract implements the following methods and events it can be called an ERC-20 Token Contract and, once deployed, itwill be responsible to keep track of the created tokens on Ethereum. Set the amount of allowance the spender is allowed to transfer from the function caller (msg.sender) balance. That allows them to be stored on the blockchain and thus protected from tampering. USD Coin is a fully collateralized stablecoin issued by a company called Circle. Like USDT, USDC is also pegged to the US dollar, which means the price of this ERC-20 token should remain at $1 at all times.
The main purpose of the guidelines behind the ERC20 standard is to promote interoperability between smart contracts. As a consequence, all infrastructure components such as user interfaces, exchanges and wallets can be connected to a contract in a predictable manner. ERC20 is the technical standard behind smart contracts serving for implementation of tokens on the Ethereum blockchain. Since its launch in 2015, Ethereum has become one of the driving forces behind the growth of cryptocurrency. Initial coin offerings (ICOs) have raised billions of dollars in funding for crypto projects from all around the world, and most of these ICOs are based on the Ethereum platform. Buyers contribute ether (ETH) to participate in a crowdfunding sale and in return receive some of the project’s tokens.
The Beginner’s Guide to ERC-20 Tokens and Addresses
Returns on the buying and selling of crypto assets may be subject to tax, including capital gains tax, in your jurisdiction. Any descriptions of Crypto.com products or features are merely for illustrative purposes and do not constitute an endorsement, invitation, or solicitation. For ERC-20 tokens, interoperability with one another and third-party services, such as the Crypto.com App and MetaMask, is achieved through the implementation of an application programming interface (API). This enables developers to fetch on-chain data about a token and use the data to trigger specific functions within their smart contract. Some of these ERC20 smart contract functions are included for security purposes. They perform checks on the sender’s balance and approvals before moving tokens.
To do so, tap ‘Buy’ from the Home Screen, then select the token to purchase and payment method. The Ethereum community, powered by the Ethereum Virtual Machine (EVM), continues to innovate with new tokens and newer standards such as ERC-1400 and ERC-998. Showing a commitment to adapt to the diverse and evolving needs of token users and creators.
However, it is still called ERC-20 because that’s how it was known until it was approved. The ERC-20 (Ethereum Request for Comments 20), proposed by Fabian Vogelsteller in November 2015, is a Token Standard thatimplements an API for tokens within Smart Contracts. This event is emitted when the amount of tokens (value) is approved by the owner to be used by the spender.

ERC-721 introduced the concept of non-fungible tokens (NFTs) with unique identifiers for each token. NFTs support complex ownership structures for use cases like virtual worlds, art, ticketing, collectibles, and more. Additional ERC-20 tokens include Compound (COMP), Basic Attention Token (BAT), Polygon (MATIC), The Sandbox (SAND), Immutable (IMX), Wrapped Ethereum (WETH), and Pepe (PEPE). These examples of ERC-20 tokens represent just a fraction of the diverse ecosystem of Ethereum-based tokens, each serving unique purposes and catering to various use cases within the DeFi ecosystem. WBTC is an ERC-20 token pegged to the value of Bitcoin, allowing users to access Bitcoin liquidity on the Ethereum blockchain. ERC-20 tokens can be easily traded, exchanged, and integrated into various Ethereum-based applications, enhancing usability and interoperability between dApps.
Introduction: What is a token standard?
- These functions provide a common structure for tokens so that they can be easily accessed, recognized, reviewed, and used.
- Ethereum is a blockchain and platform that hosts smart contracts, decentralized applications, cryptocurrencies, and other projects.
- With MoonPay’s Web3 platform, you can effortlessly generate ERC20 smart contracts, customize token parameters such as name, symbol, and supply, to deploy your tokens on the Ethereum blockchain in just a few clicks.
- JST allows users to engage directly with a suite of DeFi products offering loans, staking, and governance mechanisms, all facilitated by the low-cost and high-speed features of the TRON network.
These tokens are a representation of an asset, right, ownership, access, cryptocurrency, or anything else that is not unique in and of itself but can be transferred. ERC-20 is a token standard that outlines specifications for tokens to follow in order to function optimally on the Ethereum blockchain. With it, developers and https://ai-robert.com/ entrepreneurs can build new tokens that interoperate within Ethereum’s ecosystem of decentralized apps.
Which one is better, TRC20 or ERC20?
Without standard rules and protocols governing token behavior, interoperability between different tokens and applications posed significant hurdles for developers and users. Additionally, the fungible basis of the ERC-20 token standard is well-suited for cryptocurrency, which was and remains a prominent use case of blockchain technology. ERC-20 tokens can also be customised to include utilities for owners, such as voting rights and rewards mechanisms. MoonPay offers powerful tools that simplify the creation and deployment of ERC20 tokens, allowing developers to unleash their creativity and bring their token ideas to life.
