In reality, it will give you the option to convert your tokens with other ones. Well, the totalSupply mainly outlines the overall number of ERC20 tokens you want to create. In order to create the token, you first have to determine the total amount how to buy vthor of supply of this token.
What Crypto Users Need to Know: The ERC20 Standard
- Fungible tokens are indistinguishable from one another and can be interchanged at any given time.
- A fungible token is one that is exchangeable with another token, whereas the well-known ERC-721 non-fungible tokens (NFTs) are not.
- As a result, many people are creating needless tokens that are flooding the market unnecessarily, and in many cases, creates scam token to raise money.
- On the other hand, ERC20 smart contract will use this token to initiate the payment.
Another excellent implementation of the ERC-20 token standard is the OpenZeppelin ERC-20 implementation(opens in a new tab). For example, DogeCoin has the symbol “DOGE,” but mostly, it’s popular with DogeCoin. In reality, it’s actually quite important as it will ensure the lowest value for your token. If the divisibility is 0, then it will mean 1; if it’s 2, then the lowest value will be 0.01. So, in times of tokenization you need to remember this attribute for it. The purpose of this website is solely to display information regarding the products and services available on the Crypto.com App.
Before the ERC-20 standard was introduced, there was no common how does a crypto exchange work language for developers to use when creating tokens on Ethereum. This meant that they needed to build projects from the ground up, as well as custom blockchain bridges to exchange any token — both of which required technical knowledge. Fungible tokens are indistinguishable from one another and can be interchanged at any given time. Many tokens use the ERC-20 standard, which has become a driving force of the entire Ethereum ecosystem, with over a thousand contracts on the network. The ERC20 standard has been a dominant pathway for creating new tokens in the cryptocurrency space for some time. ERC20 was created by Ethereum developers on behalf of the broader Ethereum community in 2015 and was officially adopted in September 2017.
What is ERC20?
Ethereum Request for Comments (ERCs) were changed to address standardization and documentation for Ethereum’s application layer. Ethereum Improvement Proposals became the method for suggesting, processing, and documenting changes for Ethereum itself. Following the procedure used by the Ethereum developer community at the time, the proposal was approved and implemented in 2017 as Ethereum Improvement Proposal 20 (EIP-20). However, it is still called ERC-20 because that’s how it was known until it was approved. This accessibility has helped accelerate the Ethereum network’s growth, driving innovation and expanding the blockchain’s capabilities.
A basic implementation of ERC-20 tokens
Called Ethereum Request for Comment (ERC) 20, the standard guides token creation so that tokens compatible with the Ethereum blockchain are interchangeable. ERC-20 was proposed by developer Fabian Vogelsteller in 2015 to address the need for a standard within smart contracts on the Ethereum blockchain. Vogelsteller submitted the proposal via the project’s Github page as an Ethereum Request for Comment (ERC).

Binance also has created a side chain that runs alongside the Binance Chain called the Binance Smart Chain. This chain is compatible with ERC-20 tokens, the Ethereum Virtual Machine, and the Binance Chain; however, it uses a 7 best asic miners 2020 newer standard called BEP-20, which creates cross-chain compatibility. In 2023, Ethereum altered how changes were suggested and processed for the ecosystem by splitting its method into two separate repositories.
ERC-20 defines a common list of rules that all fungible Ethereum tokens should adhere to. Consequently, this token standard empowers developers of all types to accurately predict how new tokens will function within the larger Ethereum system. One of the most significant smart contract standards on Ethereum is known as ERC-20, which has emerged as the technical standard used for all smart contracts on the Ethereum blockchain for fungible token implementations. The original token standard of Ethereum, ERC-20 has played an integral role in the growth of blockchain projects — not only for the Ethereum network, but the entire crypto ecosystem. Its widespread adoption has opened the gates for developers to build decentralised finance (DeFi) products, games, exchanges, and much more around its standards, expanding the possibilities of decentralised technology. 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).
As it was the twentieth comment, it was assigned the designation ERC-20. Smart contracts were becoming more popular in 2015, but several issues needed to be addressed. One of the most pressing was that anyone could make a token, but they were not always interoperable with other tokens. Without a standardized token methodology, there wasn’t a way to ensure that all the different tokens could be created, used, or exchanged by everyone using the blockchain. Storing and sending ERC20 tokens can be done through Ethereum wallets like MetaMask and Ledger. These cryptocurrency wallets allow users to add ERC20 tokens from any other Ethereum wallet by transferring tokens to the corresponding wallet address.
