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.
Errors or vulnerabilities in smart contract code can result in irreversible losses of funds or unexpected behavior, highlighting the importance of rigorous auditing and testing. Once the transaction is confirmed, it is recommended to view the NFT on the mobile app version of MetaMask since collectibles are not visible on the web version for now. Fortunately, most token developers have fallen in https://ai-robert.com/ line with ERC-20 rules, meaning that most tokens released through Ethereum are ERC-20 compliant. In 2023, Ethereum altered how changes were suggested and processed for the ecosystem by splitting its method into two separate repositories. 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.
For instance, there’s already integration with the world of decentralized finance. But as DeFi continues to expand, we might see more uses for these cryptocurrencies, particularly when it comes to staking, lending, and yield farming. Shiba Inu was launched in August 2020 as a meme coin, but it grew to become a decentralized ecosystem. Even though the token didn’t offer much utility, the community behind it drove SHIB to become one of the top 10 cryptocurrencies by market cap at one point. The EVM is built with smart contract functionality, which gives these tokens properties and behaviors. The history of the ERC-20 standard is deeply interlinked with the history of Ethereum itself.
What Are ERC-20 Tokens on the Ethereum Network?
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.
ERC-20 tokens, on the other hand, are distinct tokens following the ERC-20 standard on the Ethereum network. The inception and broad acceptance of ERC20 has deeply impacted the cryptocurrency landscape. It has helped to establish a foundational standard for token interoperability, enhancing efficiency and accessibility for decentralized applications and exchanges. LINK is a cryptocurrency that enables decentralized oracle networks to connect smart contracts with external data sources. Since its inception in 2015, the Ethereum blockchain has been a pioneer in decentralized applications (dApps) and smart contracts. To address growing concerns that multiple tokens would not be transferrable on the Ethereum blockchain, a proposal for standards was made and implemented in 2015.
With almost 1,000 crypto assets that follow its specifications in circulation today, the ERC-20 token standard is one of the foundational pillars of the blockchain ecosystem. Think of it as a common language that allows different applications and exchanges to understand and interact with each other. It’s been around for a while, and it’s still the most popular way to create tokens. It’s not perfect, but it’s simple and well-understood, which is why so many people use it. Today, the ERC-20 token standard outlines rules and functions for creating and managing fungible tokens that can be exchanged for equal value and replicated within the Ethereum network. Additionally, this ensures that tokens adhering to the same standard can integrate seamlessly with wallets, exchanges, and third-party tools supporting the designated protocol.
EOS, Tron and VeChain were all originally issued as ERC-20 tokens and have now converted to their respective mainnets. On Ethereum, that ETH is an amount of computer power required in order to make your transaction work. To return to the car analogy, it’s how much gasoline is required to make the engine work and power the car to the destination you’re looking to get to.

In this article, we aim to discover together the key differences between TRC20 and ERC20, explore how tokens interact with smart contracts, and discuss their impact on the broader crypto ecosystem. It’s like having dollar bills; one dollar is interchangeable with any other dollar. They also have standard functions like transfer, balanceOf, and approve, which allow you to send tokens, check your balance, and allow other applications to use your tokens. These functions are defined in the ERC-20 standard, so everyone knows how they work. In conclusion, the ERC-20 token standard has profoundly impacted the cryptocurrency ecosystem, particularly within the Ethereum blockchain. ERC-20 has enabled interoperability, compatibility, and innovation across DApps and tokenized economies by providing a standardized token creation, transfer, and management framework.
- This event is emitted when the amount of tokens (value) is sent from the from address to the to address.
- Whether you are a seasoned trader or just getting started in the world of digital currencies, understanding these token standards will help you work with crypto more effectively.
- While ETH is a native coin of the Ethereum blockchain, it’s not an ERC-20 token itself.
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. By following these guidelines, developers can create tokens that seamlessly interact with other Ethereum-based applications, fostering a vibrant ecosystem of decentralized finance (DeFi). Prior to ERC20, there were issues with creating, using, and exchanging different tokens on the Ethereum blockchain due to a lack of standardization. ERC20 was designed as the technical standard for fungible tokens on the Ethereum network, making each token within a set identical to the others. Ethereum core developers concluded that it was not viable to promote a Wild Wild West ecosystem where developers can create different variants of tokens.
#3. Binance Coin (BNB)
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. The increasing demand for Ethereum transactions has led to network congestion and high gas fees, hindering the scalability and potential usage of ERC20 tokens.
