ERC-20 tokens are becoming the backbone of the crypto world, with universal acceptance and adoption. As the ERC-20 keeps developing, it is building the foundation of many projects with different applications. But what is ERC20? And how are they different? On this blog, we will discuss everything from the ERC20 token list to the best ERC20 wallets. We will discover what is ERC20 and how to create an ERC20 token.

ERC20 is one of the popular token standards. It is a technical specification for making fungible tokens on blockchain technology and making all tokens abide by certain rules and regulations. Fungible tokens are those that are similar and interchangeable. However, ERC-20 has been instrumental in propelling the development of decentralized finance (DeFi) and transforming the way we trade value on the blockchain. 

The tokens have opened new horizons, spurring innovation and broadening the potential of blockchain technology. ERC-20 tokens developed on the Ethereum blockchain follow a standardized protocol for compatibility and functionality. You can store them safely in wallets compatible with Ethereum. Developers introduced the ERC-20 standard in 2015. Moreover, there are many digital currencies that leverage the ERC20 standard, a few of which include Tether (USDT), USD Coin (USDC), Wrapped Bitcoin (WBTC), Uniswap (UNI), Chainlink (LINK), Binance Coin (BNB), and Aave (AAVE). 

How to Create an ERC20 Token

Building an ERC20 token on the Ethereum network requires some standardized rules to be followed and is much easier than you think. We will walk you through the steps to create an ERC-20 token:

• Start by writing a smart contract. 
• Specify the name, symbol, decimal, and total supply.
• Implement core ERC-20 functions such as balanceOf(), transfer(), transferFrom(), approve(), and allowance().
• Define required events, including Transfer and Approval, for tracking token activity.
• Compile and deploy the smart contract to the Ethereum network using development tools.
• Thoroughly test the token’s features using test accounts on a testnet environment to ensure proper functionality.
• Assign tokens to users via methods such as token sales, airdrops, or manual transfers.
• Follow best security practices and consider partnering with a professional token development company for added assurance. 

The Goal of ERC-20 Standard

Differentiating how different assets interact with one another and how they behave with different applications on the Ethereum blockchain network enables developers to predict how new tokens will act. This standard defines certain rules that must be followed while building fungible tokens. The ERC-20 standard allows developers to release new tokens without needing to verify them repeatedly. As long as the token follows the rules defined by ERC-20, there is no need to worry about the new project’s compatibility with the existing one.     

ERC20 Must-Have Functions

TotalSupply(): Give details about the total token supply that an ERC-20 holds.     

BalanceOf(): Give details about the total tokens available in the owner’s account. 

Transfer(): This function allows the user to move tokens from one place to another. 

TransferFrom(): Function similar to Transfer function, except that it sends a token from a particular address.    

Approve(): Allow the user to withdraw a limited number of tokens.  

Allowance(): Returns the number of tokens a spender is permitted to use on behalf of the token owner.

Apart from these key functions, there are 3 optional functions which are: 

Name: This is the unique token’s name

Symbol: A shortened identifier used for easy recognition.

Decimals: Specifies the number of decimal places the token supports, indicating the smallest divisible unit that can be transferred or owned.

Best ERC20 Token List

Below, we have provided the top ERC20 token list created on the Ethereum blockchain. 

1. Ethereum

Ethereum is one of the well-known ERC-10 tokens and is an expensive one, recognized for its steady growth and strong performance.

2. Vantard (VTRD)

Another booming ERC-120 token, which has been grabbing attention, is Vantard (VTRD). VTRD tends to be more cost-effective and scalable as compared to other ERC-20 tokens.   

3. Dogizen (DOGZ)

Dogizen, a new dynamic token inspired by the iconic “doge” meme, goes beyond hype by fostering strong community engagement. Moreover, the native DOGZ token empowers holders to take part in decentralized finance applications, making them active participants in shaping the Dogizen ecosystem.

4. Rexas Finance (RXT)

RXT aims to offer services that allow individuals to lend and borrow crypto directly without any third-party intermediaries. Additionally, this token leverages advanced algorithms to discover the best lending and borrowing rates.

5. Mantra (OM)

Mantra (OM) comes in fifth place in our ERC20 token list, focusing on providing a set of services to offer a safe and easy-to-use environment for DeFi apps.  

6. Render Network (RNDR)

RNDR is developed on the Ethereum blockchain network, allowing users to share their computing power by leveraging cloud services.  As demand for decentralized cloud-based rendering and cloud development continues to grow in different industries like VR, games, and entertainment, the popularity of RNDR is growing accordingly.

7. Wrapped Bitcoin (WBTC) 

Wrapped Bitcoin (WBTC) can be easily merged with Ethereum’s ecosystem. Bitcoin is experiencing strong bearish pressure, but there remains a high potential for a bullish reversal in the near future.

8) Uniswap (UNI)  

Uniswap is a well-known DEX developed on the Ethereum network that focuses on making solutions more efficient by resolving issues with automated solutions. 

9)  Aave (AAVE)  

Developed on the Ethereum network and functioning as a decentralized protocol, Aave enables users to lend and borrow cryptocurrencies more efficiently.

10) Decentraland (MANA)  

MANA is a VR program built on the Ethereum network, enabling end users to develop apps that are monetizable. Users can utilize these tokens for several uses, like owning land.

Best ERC20 Wallets to Consider in 2025

We have listed down a few best ERC20 wallets that will help you keep your Web3 assets on Ethereum and other compatible blockchains, based on their features, popularity, advantages, and disadvantages.

MetaMask

MetaMask is one of the ERC20 wallets you can consider for storing and managing your digital assets and decentralized apps. When it was introduced in 2016, it was only available as a browser extension, but now it can be accessed from multiple platforms as it is available as a mobile app. Its interactive interface allows its users to buy and sell crypto.   

Trust Wallet

Being a non-custodial wallet, Trust Wallet gives its user full authority to manage their private keys. It can be accessed via iOS or Android mobile apps, making it easy to access for its users. Users can easily buy and sell their tokens in their apps. But it does not support two-step verification, which is a key concern for many of its users. 

Ledger Nano X

Another best ERC20 wallet that comes in our list is the Ledger Nano X, established in 2019. It supports more than 5K digital assets with enhanced security, making it an ideal choice for users looking for secure ERC20 wallets. 

MyEtherWallet (MEW) 

MyEtherWallet, established in 2015, is an open-source ERC20 wallet through which users can directly interact with Ethereum. It exists in both browser extension and mobile app form and is supported by both Android and iOS.

Exodus Wallet

Exodus Wallet is a cross-platform wallet established in 2015. It is popular for offering an easy-to-use interface. Unlike MetaMask, Exodus Wallet supports non-Ethereum tokens and can be accessed through mobile, desktop, and browser.
