To learn more about token standards, including ERC-721 for NFTs, check out our University article. ERC-404 further built on the concept of semi-fungible tokens that enables fractionalized ownership for users in areas like real estate, DeFi, gaming, and more. Just as with traditional Ether tokens, all transactions involving ERC20 tokens are recorded on the Ethereum blockchain, providing traceability of all token transfers and operations on the network. An overview of ERC20, the token standard that promotes interoperability across the Ethereum blockchain network and its many applications. Now that we’ve explored all the nuances of the ERC-20 token standard, you can tell that it’s more than a technical document. It represents a foundational pillar https://ai-robert.com/ on which the world of decentralized finance and the digital economy are being built.
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.
This function is a getter and does not modify the state of the contract and should return 0 by default. As you can see, ERC-20 brings a tad of consistency into the chaotic realm of cryptocurrencies. Its implementation is considered a pivotal moment in the history of the Ethereum blockchain, and its effects are likely to continue to be recognized long into the future. While ETH is a native coin of the Ethereum blockchain, it’s not an ERC-20 token itself. On the other hand, its wrapped version has increased interoperability and can be used for staking, liquid farming, lending, and much more. The community recognized some of its drawbacks, which resulted in other standards, such as the ERC-721 NFT standard and the ERC-1155 multi token standard, being implemented.
Discover how blockchain document signing enhances crypto user experience with speed, security, and trust. Finally, the transfer function returns a boolean value—a data point representing truth or falsehood to denote the outcome of a logical condition—signifying the success or failure of the transfer operation. This returned boolean value allows callers to manage transfer outcomes, programmatically responding appropriately to transaction results. Overflow occurs when the result of adding tokens to a balance exceeds the maximum value that the data type used to store the balance can represent. Similarly, underflow happens when subtracting tokens results in a value below the minimum representable value for the data type.

As you must have noticed, it is quite easy to set up an ERC-20 address and receive tokens. One thing you must however keep in mind is that transactions involving all ERC tokens require gas fees in ETH. Therefore, ensure that you have enough ETH to pay the fee before executing transactions. ERC-20 is a format that allows developers to create their own tokens on the Ethereum network. Using computer code, the developers can set the maximum supply of their tokens and set rules for how they are issued and traded.
