It’s a bit of a wild west right now, but things are slowly starting to get more organized. It’s likely that regulatory clarity will drive adoption of tokenized assets. Right now, ERC-20 tokens are the go-to for many things, but they aren’t perfect for every situation. We might see standards designed specifically for things like supply chain management, voting systems, or even identity verification. The key is to make these standards interoperable so different systems can talk to each other.

«Token» and «Cryptocurrency» are often used interchangeably; all cryptocurrencies are tokens, but not all tokens are cryptocurrencies. Token, in the context of ERC-20 compliance, simply means a blockchain representation of something that meets the standards set by the Ethereum community to be considered a smart contract standard-compliant token. This means that other tokens can run on top of it, and decentralized applications (dapps) can be built atop it using smart contracts. ERC20, which stands for “Ethereum Request for Comments 20,” is a technical standard used for issuing and managing tokens on the Ethereum blockchain.

Smart contracts were becoming more popular in 2015, but several issues needed to be addressed. One of the most pressing was that anyone could make a token, but they were not always interoperable with other tokens. Without a standardized token methodology, there wasn’t a way to ensure that all the different tokens could be created, used, or exchanged by everyone using the blockchain. ERC-20 is the technical standard for fungible tokens created using the Ethereum blockchain. A fungible token is one that is exchangeable with another token, whereas the well-known ERC-721 non-fungible tokens (NFTs) are not. ERC20 standardizes the way these smart contracts and tokens are created, letting them be reusable in other applications.

What other Ethereum standards are there?

• With this, developers set the name, symbol, divisibility and other important token identifiers.
• Since its launch in 2015, Ethereum has become one of the driving forces behind the growth of cryptocurrency.
• By following these guidelines, developers can create tokens that seamlessly interact with other Ethereum-based applications, fostering a vibrant ecosystem of decentralized finance (DeFi).
• A token is a type of cryptocurrency which can be created by anyone, without the need for much technical know-how or skill.
• A large number of popular tokens, such as the stablecoin tether and leading oracle service Chainlink, are actually ERC-20 tokens under the hood.

Hence, they will store your private keys on your devices and expect you to write down and store your seed phrase. A seed phrase is a list of 12 random words that you are required to enter whenever you lose access to your wallet or forget your password. When it comes to ERC-20 tokens, the recommended wallets are MyEtherWallet (MEW) and MetaMask. Whatever the ERC-20 token may be, you can be sure that they are accessible via these two wallets. ERC-20 is the acronym used to refer to Ethereum Request for Comment number 20.

Smart contract risks

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 https://ai-robert.com/ 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.

You’ve probably heard of ERC-20 and ERC-721, but ERC-1155 is like their cooler, more versatile cousin. It’s designed to handle multiple types of tokens within a single smart contract, which is a big deal for efficiency and flexibility. Think of it as a container that can hold both your regular, interchangeable tokens and your unique, one-of-a-kind digital items. Storing and sending ERC20 tokens can be done through Ethereum wallets like MetaMask and Ledger.

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, 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.
