ERC-20 tokens, on the other hand, are distinct tokens following the ERC-20 standard on the Ethereum network. 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. This helps to enforce proper permissions, ensure transaction legitimacy, and prevent unauthorized transactions. 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.
The Ethereum platform leverages blockchain technology to facilitate the creation and execution of smart contracts. Smart contracts are self-executing agreements that automate specific actions when predefined conditions are met. Smart contracts eliminate the need for intermediaries and central authorities. WIN is the native token of WINkLink, a decentralized oracle network on the TRON blockchain. The project is focused on providing reliable data feeds to enable smart contract execution.
It is ideal for community-driven projects and reward-based models. Once the balance has been checked, the contract owner can give their approval to the user to collect the required number of tokens from the contract’s address. ERC-20 tokens follow a list of rules so that they can be shared, exchanged for other tokens, or transferred to a crypto-wallet. The exchange only needs to implement this transfer logic once, then when it wants to add a new ERC-20 token, it’s simply a matter of adding the new contract address to its database.

And in order to calculate how much ETH is needed to make a transaction work, the developers behind Ethereum created gas. Collectively they help Crypto Bull Run power the network, incentivize miners, and allow others to build their own tokens on top of Ethereum’s blockchain. This compliance is also necessary for Ethereum to keep the promise of scalability; it ensures compatibility between the many different tokens created using the Ethereum ecosystem.
This centralization can make exchanges vulnerable to hacking, insider attacks, or other types of security breaches. Centralized exchanges often support a wide variety of cryptocurrencies, including ERC20 and BEP20 tokens. This makes it easy to swap between different types of tokens without having to use multiple exchanges. ERC20 and BEP20 are two of the most popular token standards on Ethereum and Binance Smart Chain (BSC), respectively.
As with many cryptocurrency networks, Ethereum is not immune to growing pains. In its current form, it doesn’t scale well – trying to send a transaction at peak times results in high fees and delays. If you launch an ERC-20 token and the network gets congested, its usability could be impacted.

ERC20 provides basic functionality to transfer tokens, as well as allow tokens to be approved so they can be spent by another on-chain third party. A streamlined ERC20 token template designed for projects at the starting phase. It provides all the standard ERC20 functionalities while keeping the implementation simple and easy to deploy.

Moreover, the relatively humble requirements set by the proposal quickly turned it into a de facto standard for token creation. This problem was recognized by an Ethereum developer, Fabian Vogelsteller, so he proposed the Ethereum Request for Comment 20, or ERC-20, in late 2015. His reasoning was that every new token should feature a basic set of functions that would make it compatible with the rest of the network. 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. If a Smart Contract implements the following methods and events it can be called an ERC-20 Token Contract and, once deployed, itwill be responsible to keep track of the created tokens on Ethereum.
- Nowadays, the Ethereum ecosystem fosters tens of thousands of different cryptocurrencies with different properties and use cases.
- The inception and broad acceptance of ERC20 has deeply impacted the cryptocurrency landscape.
- Any excess Ether you don’t spend will be returned to you so you can leave the default settings if you wish.
ERC-20 is the acronym used to refer to Ethereum Request for Comment number 20. It is a standard for creating interoperable tokens on the Ethereum Virtual Machine. Fortunately, most token developers have fallen in line with ERC-20 rules, meaning that most tokens released through Ethereum are ERC-20 compliant. Read what ERC-20 means to Ethereum in particular and to all of blockchain in general. You wouldn’t want individual units with distinguishable traits, which would make them non-fungible.
