The creation of new tokens was once a complex process in the early days of cryptocurrency. Developers aiming to launch a new digital currency had to build an entirely new blockchain or rely on a fork of Bitcoin. This changed with the emergence of Ethereum, which introduced the concept of using a blockchain as a development platform. Ethereum’s introduction of the ERC-20 token model marked a significant shift, offering a blueprint for creating cryptographic tokens efficiently.
As the cryptocurrency industry evolved, new projects emerged with their own blockchain technologies. For Binance Smart Chain (BSC), the native token standard is BEP-20. This guide explores everything you need to know about BEP-20 and compares it with the widely used ERC-20 standard.
What Is BEP-20?
BEP-20 is a token standard designed specifically for the BNB Smart Chain, also referred to as Binance Smart Chain or BSC. It is fully compatible with ERC-20, the token model used on the Ethereum blockchain. This compatibility allows tokens created under both standards to interoperate seamlessly.
The BEP-20 model empowers users to create new tokens on the BNB Smart Chain with ease. The process is straightforward and does not require extensive programming knowledge. Developers no longer need to start from scratch, build a new blockchain, or limit themselves to the Ethereum token ecosystem.
Many projects leverage BEP-20’s utility to generate tokens and launch various initiatives, including those in the decentralized finance (DeFi) space. BEP-20 tokens are compatible with BSC-based smart contract technology, making them integral to many DeFi applications.
Tokenization is another key use case for BEP-20 tokens. Through tokenization, traditional financial assets can be represented on a blockchain. As a result, BEP-20 tokens can serve as digital assets that bridge traditional and digital finance. All transactions involving BEP-20 tokens are settled in BNB, the native token of the Binance Chain.
The original Binance Chain also supports BEP-20 tokens. Both blockchains operate in parallel, allowing BEP-20 tokens to be traded on Binance’s decentralized exchange (DEX) and other platforms within the Binance ecosystem.
Exploring Binance Smart Chain (BSC)
BSC, or Binance Smart Chain, is Binance’s second blockchain. It was launched in September 2020, a period when decentralized finance (DeFi) was gaining mainstream attention. Although concepts like staking, decentralized lending, and other DeFi services had existed for years, they had not yet captured the broader crypto industry’s interest.
Binance launched BSC as a development platform to attract users, talent, and projects. This strategy has proven successful, with BSC now regarded by many as one of Ethereum’s top competitors. Similarly, BEP-20 is often viewed as a direct rival to Ethereum’s ERC-20 token standard.
BSC also enables users to create smart contracts, paving the way for decentralized applications (dApps), DeFi platforms, metaverse projects, and more.
Key Parameters of the BEP-20 Standard
The BEP-20 standard includes several parameters that ensure its functionality and flexibility. Key parameters include Blacklist, Can Mint, Can Burn, and Can Pause.
The Blacklist parameter allows developers to ban or blacklist addresses associated with malicious activities. Can Mint serves as an inflationary parameter, providing the ability to mint additional tokens and increase the supply of BEP-20 tokens.
Can Burn acts as a deflationary counterpart to Can Mint. It enables the reduction of token supply through burning mechanisms, a common practice in cryptocurrency to potentially increase an asset’s value. The Can Pause parameter is an innovative feature designed to protect against attacks or platform failures. It allows users to temporarily halt token operations, though this introduces a centralized element, which is generally less favored in the crypto space.
Examples of BEP-20 Tokens
Many tokens on Binance Smart Chain adhere to the BEP-20 standard. While some are native to BSC, others represent cross-chain projects with BEP-20 versions of their tokens.
PancakeSwap, the largest decentralized exchange and automated market maker (AMM) on BSC, is a prominent example. Its native token operates on the BEP-20 standard. Autofarm, another popular yield aggregator and DEX built on BSC, also utilizes BEP-20 tokens.
Users can acquire these and other BEP-20 tokens through exchanges like Binance, Binance DEX, or PancakeSwap.
BEP-20 vs. ERC-20: A Comparative Analysis
As previously mentioned, BEP-20 and ERC-20 share similar objectives. But how do they compare, and is one superior to the other?
Both token standards share many similarities, which is unsurprising given that BEP-20 was designed as an alternative to ERC-20. Fundamentally, both serve as blueprints for token creation, sharing basic elements such as token ownership, transfer mechanisms, and issuance protocols.
The two chains are further linked through Binance Bridge, which enables interoperability between them. Transferring ERC-20 tokens to BSC requires conversion to the BEP-20 standard. Once converted, these tokens can be used on Binance Chain or dApps running on BSC.
There are no conversion fees for using this bridge, making it accessible without financial penalties. The process of transferring funds from one chain to another is known as Peg-in and is reversible, allowing tokens to move bidirectionally.
Given these features, it’s clear that both models are closely aligned. They operate on different networks but serve similar purposes, and tokens created under either standard can be converted between them. In many ways, they can be considered twin models.

BEP-20 vs. BEP-2: Understanding the Differences
Within the broader Binance ecosystem, another standard worth noting is BEP-2. BEP-2 is the token standard for Binance Chain, also known as BNB Beacon Chain, which was originally used for core operations before BSC’s development.
How do BEP-20 and BEP-2 compare? They are designed to work side by side and are highly compatible. Both chains use BNB as their native digital asset, and BNB operates seamlessly across both token models.
Although BSC functions as a standalone blockchain, it can be viewed as an extension of Binance Chain. The two share a dual architecture that facilitates communication and token exchanges between them. Users can easily swap BEP-20 tokens for BEP-2 tokens and vice versa.
This does not mean that BEP-2 tokens can be used directly on BSC or BEP-20 tokens on Binance Chain. Users must convert tokens to the appropriate standard for their desired chain. However, since each chain serves different purposes, overlap is minimal. DeFi enthusiasts, GameFi participants, and dApp users typically prefer BSC, while those using Binance DEX or Binance Chain opt for BEP-2.
Thanks to Binance Bridge, both chains enjoy high liquidity, making it easy to transfer and exchange tokens across ecosystems.
Final Thoughts on BEP-20
BEP-20 is the token model for Binance Smart Chain and bears strong similarities to Ethereum’s ERC-20. In fact, the two are compatible enough to function interchangeably. While some view the Binance and Ethereum ecosystems as competitors, this perspective is evolving as Web3 aims to unify the crypto industry.
Building connections between chains and projects is crucial for future growth, making compatibility a key focus. As long as these ecosystems collaborate to foster innovation, the industry as a whole will benefit.
