When this happens, the network slows down and transactions become more expensive. Gas is the cost the network charges in order to process your transaction. Next, accept the term of use and give the extension the go-ahead to reveal your seed phrase. It is advisable to store multiple copies of these secret words in secure locations. Once you have backed up your seed phrase, the account registration process is complete. Chances are you have found an interesting Ethereum project and you are looking to receive its native ERC-20 token.
Enter the email address where people can contact you to report security issues. Uses simpler proxy with less overhead, and requires including extra code in your contract. Lend tokens without requiring collateral as long as they’re returned in the same transaction.
Ethereum basics
The 0x protocol is an open protocol that enables peer-to-peer asset exchanges on the Ethereum blockchain. An initial coin offering is an unregulated means by which funds are raised for a new cryptocurrency venture. The ERC20 standard has been a dominant pathway for the creation of new tokens in the cryptocurrency space for some time. It has been particularly popular with ICOs and crowdfunding companies. There have now been tens of thousands of distinct tokens that have been issued and are operating according to the ERC20 standard.
Additionally, new projects won’t need to worry about compatibility with old projects as long as the token follows the rules. Ethereum Request for Comment 20 (ERC-20) is the implemented standard for fungible tokens created using the Ethereum blockchain. Some of the less common standards are the ones used in non-fungible tokens . Sometimes, your use case actually benefits from having unique tokens with different attributes. If you wanted to tokenize a one-of-a-kind piece of art, in-game asset, etc., one of these contract types might be more appealing.
The conventions set out don’t restrict development, so parties can implement additional features and set specific parameters to suit their needs. Authored by Vitalik Buterin and Fabian Vogelsteller in 2015, ERC-20 proposes a relatively simple format for Ethereum-based tokens. By following the outline, developers don’t need to reinvent the wheel. Instead, they can build off a foundation already used across the industry.
ERC-20 is a technical standard emerged to use for all smart contracts on the Ethereum blockchain for token implementations. The ERC-20 Ethereum token standard is a blueprint for creating fungible tokens that are compatible with the broader Ethereum network. One of the major concepts that govern a large portion of the space, and which is especially relevant to smart contracts and smart property, is what is known as the ERC20 token standard.
For example, tokens that are used as currencies may benefit more from being more divisible than a token that represents ownership of a property. Suppose that you have a huge amount of BinanceAcademyTokens, and you want to set up weekly recurring payments to a streaming DApp. You’re busy reading Binance Academy content day and night, so you don’t want to take the time every week to create a transaction manually.
Many other tokens, blockchains, and ecosystems have derived from Ethereum. One such ecosystem and blockchain belongs to Binance, the cryptocurrency exchange. The team behind Binance created its own blockchain, the Binance Chain, from an Ethereum fork. Consequently, this token standard empowers developers of all types to accurately predict how new tokens will function within the larger Ethereum system. This simplifies the task for developers; they can proceed with their work, knowing that every existing project won’t need to be redone every time a new token is released.

An Introduction to ERC-20 Tokens
Compared to the analysis done by its internal team using internal review tools, ChatGPT only hit 60% accuracy. The main issue was where the AI tool labelled high-risk assets as low-risk 50% of the time. The test focused on performing automated token reviews that utilized Coinbase’s own ERC-20 token review framework. Coinbase notes that “ChatGPT did not hit the accuracy bar to clearly demonstrate that it should be integrated into our asset review process,” though the exchange states that it did show potential. Coinbase has conducted a test to see ChatGPT’s utility in conducting security analysis for ERC-20 tokens.
In this article, we’ll look at the ERC-20 standard, an important framework for creating tokens. While it’s specific to the Ethereum network, the framework also inspired other blockchain standards, such as Binance Chain’s BEP-2. There are several ERC20-compliant tokens deployed on the Ethereum blockchain, but with distinct and unique implementations. Depending on the approach, the tokens can be used to represent various kinds of digital assets or tradable goods . Additionally, ERC-20 tokens may be used as a mean to tokenize voting rights during elections. As of December 2020, there are 829 projects based on the ERC-20 token standard and over 350,000 token contracts, according to a dynamic list from Ethereum data provider, Etherscan.
Many blockchain platforms have been hyped as the next “Ethereum killer,” but Ethereum has managed to keep its No. 2 ranking just behind Bitcoin. 🐢 Slow transactions – The block time is around 14 seconds, so transactions can take up to a minute to process. 💻 Fungible – The code of each individual token is the same as any other, though transaction histories can be used to identify and separate out the tokens involved.

What Is the ERC-20 Ethereum Token Standard?
ERC-20 refers to a technical standard that defines a common set of rules such as how the tokens can be transferred, how transactions are approved, and the total supply of tokens. The ERC-20 standard arose from a 2015 proposal that was merged into the Ethereum protocol via an Ethereum Improvement Proposal (IEP-20). CoinDesk is an independent operating subsidiary of Digital Currency Group, which invests in cryptocurrencies and blockchain startups. CoinDesk journalists are not allowed to purchase stock outright in DCG. The following standard allows for the implementation of a standard API for tokens within smart contracts.
The ERC-20 standard has seeped into almost every corner of the crypto ecosystem. A large number of popular tokens, such as the stablecoin tether and leading oracle service Chainlink, are actually ERC-20 tokens under the hood. Transfers _value amount of tokens to address _to, and MUST fire the Transfer event.
What Are ERC-20 Tokens, Gas, ETH? Ethereum’s Architecture Explained
This post will walk you through the process of creating an ERC20 token with the OpenZeppelin Contracts Library. Some examples of ERC-20 tokens that work in the Ethereum network are EOS , TRON , ICON , OmiseGO , Zilliqa , etc. Note Transfers of 0 values MUST be treated as normal transfers and fire the Transfer event. OPTIONAL – This method can be used to improve usability, but interfaces and other contracts MUST NOT expect these values to be present. ERC20 contains several functions that a compliant token must be able to implement.

That gas price rises and falls, depending on how busy the Ethereum network is, i.e. how many transactions need to be verified. And in order to calculate how much ETH is needed to make a transaction work, the developers behind Ethereum created gas. Collectively they help power the network, incentivize miners, and allow others to build their own tokens on top of Ethereum’s blockchain.
Several projects are already using the technical standard, and the number of ERC-20 token contracts has grown drastically in the last couple of years. In mid-2017, there were around 5,500 ERC-20smart contracts on the Ethereum network. In early 2018, this number grew to over 40,000 and is now more than160,000. The logic of smart contracts allows for some interesting use cases, even just for the creation of a set of tokens.
ERC-20 tokens have removed some of the barriers of projects wanting to work with one another, so their creation has improved and changed blockchain technology once and for all. Learn more about Consensus 2023, CoinDesk’s longest-running and most influential event that brings together all sides of crypto, blockchain and Web3. Ethereum Improvement Proposals describe standards for the Ethereum platform, including core protocol specifications, client APIs, and contract standards. ERC621 is another alternative, which proposes the same basic functions that ERC20 provides but also adds the capacity to increase or decrease the total token supply.
The custom token contract inherits from ERC20 and ERC20Votes contracts from the OpenZeppelin library. The ERC20Votes contract is an extension of the ERC20 contract that adds support for token-based voting using the EIP-712 standard. The ERC20Permit contract adds support for the EIP-2612 permit function, which allows users to approve token allowances with a signature rather than requiring an on-chain transaction. _mint function, which is provided by the ERC20 contract from OpenZeppelin. It creates new tokens and adds them to the balance of the specified address.
