These smart contracts define the token’s properties, including the token’s name, symbol, supply, and rules for transferring tokens between accounts. Launched in 2015 as a decentralized, blockchain-based global supercomputer that could serve as the foundation for an ecosystem of interoperable, (dApps) powered by token economies. However, the Ethereum developer community quickly realized that to create this ecosystem, they needed a shared standard for building the crypto tokens that powered those dApps. Ethereum Request for Comment 20 (ERC20) is a standard for https://ai-robert.com/ the Ethereum blockchain that requires certain scripting functions and two events that must be used when creating a fungible token within a smart contract.
With this, developers set the name, symbol, divisibility and other important token identifiers. This standard is called BEP-2 and is similar to ERC-20 in that it guides token creation for use on the Binance Chain. 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. Additionally, new projects won’t need to worry about compatibility with old projects as long as the token follows the rules.
ICOs, DeFi, and Beyond
ERC20 compliant tokens have been issued during Initial Coin Offerings (ICOs). Finder US is an information service that allows you to compare different products and providers. We do not recommend specific products or providers, however may receive a commission from the providers we promote and feature. Whether products shown are available to you is subject to individual provider sole approval and discretion in accordance with the eligibility criteria and T&Cs on the provider website. MoonPay offers an easy and fast way to buy, sell, and manage ERC-20 tokens using fiat currency.
What is ETH?
This function is a getter and does not modify the state of the contract and should return 0 by default. As you can see, ERC-20 brings a tad of consistency into the chaotic realm of cryptocurrencies. Its implementation is considered a pivotal moment in the history of the Ethereum blockchain, and its effects are likely to continue to be recognized long into the future. While ETH is a native coin of the Ethereum blockchain, it’s not an ERC-20 token itself. On the other hand, its wrapped version has increased interoperability and can be used for staking, liquid farming, lending, and much more. The community recognized some of its drawbacks, which resulted in other standards, such as the ERC-721 NFT standard and the ERC-1155 multi token standard, being implemented.
- To get started, just top up your wallet in euros, pounds, or dollars and use your MoonPay Balance to buy ERC-20 tokens like Tether, USDC, and SHIB.
- Each token has its own specific utility, such as granting users the right to vote on decisions impacting the future of a project, or rewarding customers for performing certain tasks.
- Fragmentation across different blockchains and standards can limit network effects and create confusion.
- Crypto.com may not offer certain products, features and/or services on the Crypto.com App in certain jurisdictions due to potential or actual regulatory restrictions.
ERC-20 tokens are typically sold via a variety of different offerings as a way to raise early-stage capital for the underlying project. In the past, however, critics have argued that crypto tokens have drawn too much hype, becoming a vehicle for sour investments or straight-up scams. Many of the projects that raised money in the initial coin offering boom of 2017 reportedly failed to provide any returns for their investors. Gas fees are the transaction fees users pay when sending ERC-20 tokens or interacting with smart contracts on the Ethereum blockchain. These fees are paid in Ether (ETH), the native cryptocurrency of the Ethereum network.
Just like Bitcoin, Litecoin, and any other cryptocurrency, ERC20 tokens are blockchain-based assets that have value and can be sent and received. The difference is that instead of running on their own blockchain, these tokens are issued on the Ethereum network. This means they’re hosted by Ethereum addresses and are sent using Ethereum transactions. Developers can create ERC-20 tokens by deploying smart contracts on the Ethereum network.
It’s a bit of a wild west right now, but things are slowly starting to get more organized. It’s likely that regulatory clarity will drive adoption of tokenized assets. Right now, ERC-20 tokens are the go-to for many things, but they aren’t perfect for every situation. We might see standards designed specifically for things like supply chain management, voting systems, or even identity verification. The key is to make these standards interoperable so different systems can talk to each other.
