Ethereum is a popular chain in the country of blockchains, and for good reasons. It is the second-largest cryptocurrency platform in the world, and it is the platform of choice for developers who want to create decentralized apps on the blockchain.

With the introduction of Ethereum in 2015, new possibilities for decentralization were opened up, including the construction of decentralized apps and the usage of smart contracts, which were previously impossible. The Ethereum ecosystem’s functionality is defined by the ERC-20 & ERC-721 token specifications. As a result, Ethereum tokens began to surge in popularity in 2016 as well as 2017,  giving birth to the ERC-20 vs ERC-721 debate. Let’s get to know them a little better.

What is ERC-721?

ERC-721 is an Ethereum token standard for Non-Fungible Tokens (NFT). Fungible refers to anything that is interchangeable and replaceable, such as Bitcoin, since every Bitcoin may replace another Bitcoin. Every NFT, on the other hand, is one-of-a-kind. One NFT cannot be used in lieu instead.

Furthermore, ERC-721 is a standard, which is a framework or template that other programmers agree to use. Developers employ the same principles to make code simpler, more predictable, and more reusable. These standards are optional, however adopting a widely known standard implies interoperability with exchanges, decentralized apps, & wallets.

What is ERC-20?

The ERC-20 token is considered to be one of the most important Ethereum tokens. This standard has evolved as the technical standard for token implementation on the Ethereum blockchain; it can be used for all smart contracts on the blockchain, and it specifies a set of criteria that all Ethereum-based assets must follow in order ordered valid.

ERC-20 is comparable to bitcoin, Litecoin, and any cryptocurrency in that it is a blockchain-based asset that has value and can be transmitted and received; although, ERC-20 tokens are not a cryptocurrency in the traditional sense. The key distinction between ERC-20 tokens and other cryptographic tokens is that they are released on the Ethereum platform rather than on their blockchain.

Which Crypto is ERC-20? 

Which Crypto is ERC-20

On the Ethereum network, more than 300 coins are built on the ERC-20 standard & operate on the Ethereum blockchain. Here are a few examples:

Ox: A decentralized exchange mechanism that is available to all participants. Trades are executed by a system of smart contracts, which can be accessed by Dapps. This supplies them with a source of liquid assets.

OmiseGO: It is a decentralized network that provides payment solutions for finance companies organizations. A version of Ethereum that leverages the plasma protocols to speed up network performance is based on this project. With its initial coin offering, the Thailand-based startup raised moreover $25 million.

Augur: It seeks to make it possible for anybody to speculate upon derivatives, but it does so in conjunction with a mechanism that rewards the ‘knowledge of the community.’

Wrapped Bitcoin (WBTC): An ERC-20 token that is backed Equally by Bitcoin, which can subsequently be used as collateral in decentralized finance (Defi) apps, hence increasing the liquidity of the market.

ERC20 vs ERC721:

ERC-20 vs ERC-721

There are many distinguishing characteristics of the tokens in the erc721 vs erc20 dispute that bring the public’s attention to them. A complete explanation of the two unique ERC token standards, erc721 and erc20, might aid in better understanding the differentiating factors of erc20 vs erc721 tokens.

ERC721 vs ERC1155:

Because of its extra characteristics, the new erc1155 token standard could become considerably more widely used in the soon erc721 token standard, which is now the most often used. Both enable you to create new NFTs, however, there are several significant differences in erc721 vs erc1155 which are discussed below:

What is an ERC20 token worth?

There are about 364,000 ERC20 tokens in circulation at the moment. The value of a token is determined primarily by supply and demand; the most valuable cryptocurrencies are Binance Coin (BNB), which has a market capitalization of $39 billion, Tether (USDT), which has a market capitalization of $35 billion, and Chainlink (LINK), which has a market capitalization of ten billion dollars.


The ERC-20 & ERC-721 tokens serve as the cornerstones of the vibrant Ethereum ecosystem, which is now undergoing rapid expansion. They serve as the basis for the definition of smart contracts, which are the building blocks of current blockchain-based decentralized services, such as cryptocurrency exchanges.

Developers must know the differences between ERC-721 & ERC-20 to choose the best token standard. Because the two token standards reflect asset ownership and access flexibility differently, the variations in access flexibility are considerable. The rising need for non-fungible tokens has made ERC-721 tokens a hot topic right now. However, the essential functionalities of ERC-20 tokens cannot be overlooked as well as ERC-1155 is also a rising member of the community.
