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. The team behind SHIB created a decentralized exchange, Shibaswap, where users can trade and stake their tokens. There are thousands of ERC-20 tokens, and developers keep creating more regularly. Still, most of them likely aren’t of importance to the average investor or enthusiast. The ERC-20 standard defines six mandatory and three optional functions that each token must feature. As the Ethereum platform grew to become one of the biggest and most used blockchains in the world, so did the need for some sort of standardization.
Is ERC-20 the Same As ETH?
It is a standard for creating interoperable tokens on the Ethereum Virtual Machine. 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. Set the amount of allowance the spender is allowed to transfer from the function caller (msg.sender) balance. That allows them to be stored on the blockchain and thus protected from tampering. USD Coin is a fully collateralized stablecoin issued by a company called Circle. Like USDT, USDC is also pegged to the US dollar, which means the price of this ERC-20 token should remain at $1 at all times.
One of the biggest is that it doesn’t handle non-fungible tokens (NFTs) very well. It also has some issues with token approvals, which can be confusing for users. Despite these limitations, ERC-20 is still the most popular token standard on Ethereum. Many projects launch their own tokens to raise money or to power their platforms.

Errors or vulnerabilities in smart contract code can result in irreversible losses of funds or unexpected behavior, highlighting the importance of rigorous auditing and testing. Once the transaction is confirmed, it is recommended to view the NFT on the mobile app version of MetaMask since collectibles are not visible on the web version for now. Fortunately, most token developers have fallen in line with ERC-20 rules, meaning that most tokens released through Ethereum are ERC-20 compliant. In 2023, Ethereum altered how changes were suggested and processed for the ecosystem by splitting its method into two separate repositories. Ethereum Request for Comments (ERCs) were changed to address standardization and documentation for Ethereum’s application layer. Ethereum Improvement Proposals became the method for suggesting, processing, and documenting changes for Ethereum itself.
- In most cases, airdropped tokens are obscure digital assets that are yet to list on exchanges.
- Formal verification methods can also be used to mathematically prove the correctness of a smart contract.
- Fungible tokens are indistinguishable from one another and can be interchanged at any given time.

Given its role in transparency, accountability, and usability within the ERC-20 token ecosystem, the “balanceOf” function is indispensable. It grants users real-time visibility into token ownership, enabling informed decisions regarding token transfers, transactions, and interactions on the Ethereum blockchain. In the early days of Ethereum, developers faced challenges in standardizing token creation and interaction, leading to fragmentation and inefficiencies within the network.
