It also serves as a governance token that enables users to participate in protocol governance. ERC-20 tokens can be stored and managed using a wide range of Ethereum wallets, ensuring easy access for users across different platforms and device types. Although not mandatory, these three functions may be useful to users and developers alike that may interact with the specific coin. For example, the name and symbol can help identify the token so users don’t accidentally buy or send the wrong one. As the network continues to grow, we can expect to see ERC-20 tokens gain more utility.
This decentralized ledger of financial transactions is constantly evolving, with new data continuously added. 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. Token standards are important because they ensure that different tokens can work together without issues.
What are blockchain token standards?
Gas fees can fluctuate based on network congestion and 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.
This not only allows developers to use tokens and contracts that have already been created, but it allows them to be easily inspected by interested parties, increasing transparency and trust in the system. Staking involves actively participating in transaction validation (similar to mining) on a PoS-based blockchain. Users who hold the minimum required balance of a specific cryptocurrency can validate transactions and earn rewards. These rewards are set by the network and are then sent to the user’s wallet. At its core, the ERC20 https://ai-robert.com/ standard defines a common list of rules that an Ethereum token has to implement, giving developers the ability to program how new tokens will function within the Ethereum ecosystem.
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.
A contributing tech reporter at CoinDesk, Alyssa Hertig is a programmer and journalist specializing in Bitcoin and the Lightning Network. She’s currently writing a book exploring the ins and outs of Bitcoin governance. „Critical problems” with the standard have been used to steal at least US$3 million, and during periods of high Ethereum congestion transactions can take long periods of time to process.
ERC-20 Token FAQ
Since then, the ERC20 standard has been a dominant pathway for creating new tokens in the cryptocurrency space for some time. As an ERC20 token, USDC benefits from the security and interoperability of the Ethereum network, making it easily integrated into wallets, exchanges, and other financial applications. The Ethereum network, with its bright smart contract features, has become a fertile ground for a wide variety of ERC20 tokens.

- This smart contract prevents parties from acting in bad faith because asset transfers are completed automatically, outside the control of the transactions, once they agree to the transaction.
- Still, if this digital ecosystem is to prosper, there has to be some order, which is where the ERC-20 standard comes into play.
- These standards ensure that different applications can interact with tokens in a predictable way.

However, the programmability of the network combined with a lack of uniformity led to compatibility issues. Ultimately, the implementation of the ERC-20 standard has proven to be a pivotal point in the development of the Ethereum ecosystem. It streamlined the creation process for new tokens while facilitating a close-knit and user-friendly environment.

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 the Ethereum blockchain that requires certain scripting functions and two events that must be used when creating a fungible token within a smart contract.
