For ERC-20 tokens, interoperability with one another and third-party services, such as the https://ai-robert.com/ Crypto.com App and MetaMask, is achieved through the implementation of an application programming interface (API). This enables developers to fetch on-chain data about a token and use the data to trigger specific functions within their smart contract. 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.
Tether (USDT) is widely used in many decentralized applications, such as DEXs and liquidity pools. The proliferation of ERC20 tokens has contributed much-needed liquidity to the Ethereum ecosystem, fueling the growth of applications like decentralized exchanges (DEXs) and liquidity pools. Binance also has created a side chain that runs alongside the Binance Chain called the Binance Smart Chain. This chain is compatible with ERC-20 tokens, the Ethereum Virtual Machine, and the Binance Chain; however, it uses a newer standard called BEP-20, which creates cross-chain compatibility.

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.
However, it is still called ERC-20 because that’s how it was known until it was approved. The ERC-20 (Ethereum Request for Comments 20), proposed by Fabian Vogelsteller in November 2015, is a Token Standard thatimplements an API for tokens within Smart Contracts. This event is emitted when the amount of tokens (value) is approved by the owner to be used by the spender.

Why is it important to choose the right token standard?
- On May 23, 2024, the Securities and Exchange Commission approved a rule change to allow exchange-traded funds to buy and hold ether on behalf of U.S. investors.
- Fungible tokens are indistinguishable from one another and can be interchanged at any given time.
- This returned boolean value allows callers to manage transfer outcomes, programmatically responding appropriately to transaction results.
- Moves the amount of tokens from the function caller address (msg.sender) to the recipient address.
- Formal verification methods can also be used to mathematically prove the correctness of a smart contract.
Without standard rules and protocols governing token behavior, interoperability between different tokens and applications posed significant hurdles for developers and users. Additionally, the fungible basis of the ERC-20 token standard is well-suited for cryptocurrency, which was and remains a prominent use case of blockchain technology. ERC-20 tokens can also be customised to include utilities for owners, such as voting rights and rewards mechanisms. MoonPay offers powerful tools that simplify the creation and deployment of ERC20 tokens, allowing developers to unleash their creativity and bring their token ideas to life.
Called Ethereum Request for Comment (ERC) 20, the standard guides token creation so that tokens compatible with the Ethereum blockchain are interchangeable. One such ecosystem and blockchain belongs to Binance, the cryptocurrency exchange. The team behind Binance created its own blockchain, the Binance Chain, from an Ethereum fork. Chainlink aims to connect the real world with blockchain through Decentralized Oracle Networks (DONs).
The Beginner’s Guide to ERC-20 Tokens and Addresses
Cryptocurrency token standards enable interoperability so that native coins of one blockchain can be transferred to and traded on another. This interoperability facilitates token exchange and transfer across different platforms and services, fostering the development of intricate decentralized systems. Token standards are a category of smart contract parameters, which lay out application-level guidelines about how a smart contract functions on its underlying blockchain. A token standard more specifically addresses parameters like token supply, transaction approval, and accessibility of the token’s data. The ERC-20 Ethereum token standard is a blueprint for creating fungible tokens that are compatible with the broader Ethereum network.
It incentivizes users to share their bandwidth and resources, improving the network’s overall performance and speed.

Almost anything that can be owned, can also be tokenised – be it corporate shares, real estate, works of art, rights of use, vehicles…the list goes on.
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.
