Flexibility in token standards allows developers to customize tokens to meet specific use cases and requirements. Through features such as token minting, burning, pausing, freezing, and metadata management, developers can implement innovative token models that cater to diverse business needs and user preferences. Before the ERC-20 standard was introduced, there was no common language for developers to use when creating tokens on Ethereum. This meant that they needed to build projects from the ground up, https://ai-robert.com/ as well as custom blockchain bridges to exchange any token — both of which required technical knowledge. ETH is the native cryptocurrency of the Ethereum blockchain, serving network operations and used to pay for transaction fees.
Flexibility and Community Adoption
In other words, ERC-20 is what ensures that users can buy, swap, and HODL the many cryptocurrencies built on this standard. Without this framework, developers would create tokens using unique codebases and toolkits that could not interact with one another or protocols in predictable ways. With more than 1,000 tokens in circulation, the use cases for ERC-20 continue to expand. ERC-20 tokens represent a large variety of assets, both digital and physical. There are ERC-20 tokens that represent real estate, art, stocks, unused hard drive space, and more.
How do I know if my USDT is ERC20 or TRC20?

This makes it easier for developers to build and users to use various applications. As governments start to figure out how to deal with blockchain and tokens, it’s going to have a huge impact on what standards are used and how they’re implemented. We might see standards that are specifically designed to comply with certain regulations, making it easier for businesses to use blockchain without running into legal trouble.
The future of the ERC-20 standard
- Many of the projects that raised money in the initial coin offering boom of 2017 reportedly failed to provide any returns for their investors.
- This getter returns the remaining number of tokens that the spender will be allowed to spend on behalf of owner.
- Moves the amount of tokens from sender to recipient using the allowance mechanism.
- Recognizing the need for a unified token standard, Fabian Vogelsteller, a developer in the Ethereum community, proposed the ERC-20 standard in late 2015.
Some of these rules include how the tokens can be transferred, how transactions are approved, how users can access data about a token, and the total supply of tokens. Think of it as a common language that allows different tokens to interact with each other and with various applications. Without these standards, things would be chaotic, like trying to plug a foreign appliance into an outlet without an adapter. ERC20 is a technical standard for tokens issued on the Ethereum blockchain, providing a list of rules that all Ethereum-based tokens must follow.
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.
