For one, almost anything that can be owned, can also be tokenised – be it corporate shares, real estate, works of art, rights of use, vehicles…the list goes on. If you’re buying any digital currency that’s issued as an ERC20 token, you’ll need to find a wallet that’s compatible with these types of tokens. Happily, because ERC20 tokens are so popular, there are plenty of wallets to choose from. The “balanceOf” function finds extensive utility across DApps and token-based protocols. For example, wallets and portfolio trackers utilize the “balanceOf” function to give users insights into their token holdings and overall account balances. Before initiating the transfer process, the function undergoes a series of validations that ensure the sender possesses a sufficient token balance to cover the transfer amount.
- Cryptocurrency token standards enable interoperability so that native coins of one blockchain can be transferred to and traded on another.
- While ERC-20 remains the definitive Ethereum token standard, there are several new token standards currently in development.
- It’s also relatively simple to implement, which makes it a good choice for new projects.
- The history of the ERC-20 standard is deeply interlinked with the history of Ethereum itself.
Comparison with ERC-20 and ERC-721
This allows Ethereum to provide a complete ecosystem that provides anything crypto enthusiasts might need to purchase, sell, or transfer tokens, as well as complete many other crypto-related activities. ERC-721 tokens are used for things like digital art, collectibles, and in gaming, where each item needs to be unique and cannot be exchanged one-for-one. ICOs, or token sales, are events where investors acquire tokens in return for funding a project in the hope that the project will be successful, the token will increase in value and/or yield returns. The initiators of an ICO, in turn, need money from investors to fund the project.
One of the biggest is that it doesn’t handle non-fungible tokens (NFTs) very well. It also has some issues with token approvals, which can be confusing for users. Despite these limitations, ERC-20 is still the most popular token standard on Ethereum. Many projects launch their own tokens to raise money or to power their platforms.

Cryptocurrency token standards enable interoperability so that native coins of one blockchain can be transferred to and traded on another. This interoperability facilitates token exchange and transfer across different platforms and services, fostering the development of intricate decentralized systems. Token standards are a category of smart contract parameters, which lay out application-level guidelines about how a smart contract functions on its underlying blockchain. A token standard more specifically addresses parameters like token supply, transaction approval, and accessibility of the token’s data. The ERC-20 Ethereum token standard is a blueprint for creating fungible tokens that are compatible with the broader Ethereum network.
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.
Gas fees can fluctuate based on network congestion and https://ai-robert.com/ the complexity of the transaction. For instance, high traffic or complex smart contracts can lead to users paying higher fees. ERC-20 is the common set of criteria that outlines rules and technical specifications an Ethereum token must follow to function optimally and interoperably on the Ethereum blockchain. Tokens are developed using smart contracts, which are self-executing software programs that define how blockchain protocols automatically control, execute, and/or document transactions.
