BEP2 vs BEP20 vs. ERC20: Which is better?

As such, these can be used to represent a wide range of digital assets, such as art, collectibles, or game items. The ERC-20 token standard is a major part of the Ethereum ecosystem and continues to be used by developers around the world to create powerful, reliable, and secure applications. As if blockchain, cryptocurrency, and non-fungible tokens weren’t complicated enough, all of these ERCs and EIPs can feel daunting. Ethereum’s open and public nature means that this one is pretty easy to learn more about as far as currency systems go.

  • According to the official documentation, three parameters are correct for both standards.
  • That said, remember that when NFTs are in question, you must create or outsource your NFT-representing files and upload them to a proper Web3 storage solution.
  • The first token standard created for Ethereum was ERC20, which was released in 2015.
  • ERC721, on the other hand, is a non-fungible token standard that defines unique tokens that can represent digital assets such as collectibles, in-game items, or real estate.
  • The popularity of ERC-20 stems from its simplicity and the fact that it allows for the creation of secure, interchangeable tokens on the Ethereum network.

The critical distinction between fungible and non-fungible assets is the information they contain. Non-fungible tokens store data, such as an academic title or an artwork—however, fungible tokens, such as Bitcoin, store value. XRC-20 tokens are Ethereum’s solution for streamlining the procedure of token integration and their regulation. This token standard further helps developers create a smart contract for tokenizing any “Fungible” asset.


The recent boom of NFT that you’re experiencing can be credited to the emergence of ERC-721. The new protocol allowed creating a marketplace for artists, gamers, and everyone who has something unique to sell. The sale of a $69 million digital artwork by the artist named Beeple wouldn’t have been possible had there not been this token standard. The crypto bull run of 2017 might have been a significant factor behind the rise of ERC-20 tokens. Tether, Chainlink, USDC, DAI — are all prime examples of cryptocurrencies built on the foundation of ERC-20 tokens. Despite being the popular token standard, it cannot be the jack of all trades.


It is again important to note that the tokens live on the Ethereum blockchain. They aren’t independent and rely on Ethereum’s blockchain and platform. The native currency on the Ethereum network is Ether but it can also support other tokens and these can work like currencies that can represent shares of a company, gold certificates, and so on.

What are ERC-721 and ERC-1155: Standards for Creating NFTs

Anyone can create an ERC since Ethereum is an open-source, decentralized network. To do this, one must undergo the process of an “Ethereum improvement proposal” . Via this document, a developer needs to express proposed features and processes for the Ethereum blockchain network.


With the growing demand for NFTs, ERC-721 tokens are definitely a hot topic now. However, the basic functionalities of ERC-20 tokens cannot be left out of the equation in any case. Learn more about ERC tokens and find out the suitable option for your use cases. Other than this, it also allows the transfer of an amount equivalent to a token to a third party.

ERC-721: Non-fungible tokens(NFT)

Some rules are laid down by programmers in these templates or documents that Ethereum-based tokens must comply with. Functionalities such as transferring tokens from one account to another, to get the current token balance of an account, and the total supply of the token available on the network. ERC-20 and ERC-721 tokens are the initial types of ERC token standards that serve an important role in defining the functionality of the Ethereum ecosystem. Created by Enjin CTO Witek Radomski in 2018, ERC-1155 opened a new window in the Ethereum blockchain.

Ethereum development has paved the way for two prominent token standards, ERC20 and ERC721, each serving unique purposes in the blockchain world. While both standards have their own unique features and benefits, they also differ in several key ways. It was proposed in 2015 and was finally integrated with the Ethereum blockchain in 2017.

Ethereum as a platform has enabled the rapid issuance and transfer of tokens that are secured by the underlying blockchain technology. A standard interface for contracts that manage multiple token types. A single deployed contract may include any combination of fungible tokens, non-fungible tokens or other configurations (e.g. semi-fungible tokens).

“transfer” component in the token focuses on enabling the transfer of a specific number of tokens to a user account from the total supply. The onERC721Received function specifically works around old deployed contracts which may inadvertently return 1 in certain circumstances even if they don’t implement a function . By returning and checking for a magic value, we are able to distinguish actual affirmative responses versus these vacuous trues. We have required name and symbol functions in the metadata extension. Every token EIP and draft we reviewed (ERC-20, ERC-223, ERC-677, ERC-777, ERC-827) included these functions. Creation of NFTs (“minting”) and destruction of NFTs (“burning”) is not included in the specification.

ERC-721 Tokens

However, this standard also targets fungible tokens , and semi-fungible tokens . This makes it the first standard for multi-token minting and transaction management. In addition, ERC1155 is a universal token standard that supports transfers of different types of tokens in a single instance. Plus, just like with “ERC721”, “ERC1155” also refers to smart contracts and tokens marching to the beat of this standard. The limitations of both the ERC-20 and ERC-721 tokens results in the creation of ERC-1155. In ERC-20 tokens, when users accidentally send the tokens to a wrong address, what they have transferred is lost forever due to the lack of a way to solve these transfer events.

I hope this article helped narrow down your choices But if you still need any help, consult with our experienced developer for best suggestions. Overall, the ERC-1155 standard is a powerful tool for developers, providing a secure and efficient way to create and manage a variety of tokens. It offers increased flexibility, improved gas cost, and simpler transaction processing, making it a great choice for developers who want to take advantage of the Ethereum blockchain.

What are ERC-20 and ERC-721 standards?

Additionally, tokens can be transferred to multiple addresses in a single transaction, which is not possible with the traditional ERC-20 or ERC-721 standards. This allows for simplified and streamlined token management, enabling faster and more efficient transfer of tokens. Since then, numerous token standards have been developed, each adding additional features and capabilities to the tokens. These include ERC223, ERC721, ERC777, and ERC1155, all of which offer more advanced features than ERC20. These two case studies illustrate how a deed is separate from the thing which it declares ownership over.

The ERC-721 non-fungible token standard is written in Solidity language on the Ethereum blockchain and it allows developers to tokenize ownership of any arbitrary data. These events include Transfer, Approval, and others, and can be useful for tracking the activity of the token on the Ethereum network. Overall, these components and events form the basis of an ERC-20 token, and provide a standard way for smart contracts to interact with one another on the Ethereum network. Non-fungible tokens are unique and indivisible, representing assets such as artwork, collectibles, and real estate. Each NFT is unique and has its own distinct value, and cannot be replaced or exchanged for an equivalent.
