In the early stages of cryptocurrency, creating new tokens was not an easy task. Developers who wanted to launch digital currencies had to build a new blockchain or use a Bitcoin fork. This changed with the emergence of Ethereum, which began using blockchain as a development platform. Later, a new token model called ERC-20 was introduced, serving as a blueprint for cryptographic token creation.
As the cryptocurrency industry matured, new projects emerged with their own blockchain technology. For Binance Smart Chain (BSC), the token standard is BEP-20. This guide covers everything you need to know about it and compares it to ERC-20.
Understanding BEP-20
BEP-20 is a token standard created for the BNB Smart Chain, also known as Binance Smart Chain or BSC. It is compatible with ERC-20, the token model used on the Ethereum blockchain. This means both token models can work together seamlessly.
The BEP-20 token model allows users to create new tokens easily on the BNB Smart Chain. The process is straightforward and does not require extensive programming experience. Developers no longer need to start from scratch, build a new blockchain, or limit themselves to the Ethereum Token Standard.
Many projects leverage BEP-20 to generate tokens and launch various initiatives. BEP-20 tokens are compatible with BSC-based smart contract technology, often used in decentralized finance (DeFi).
These tokens also play a role in tokenization. Through tokenization, traditional financial assets can be linked to a blockchain. Thus, BEP-20 tokens serve as digital assets bridging traditional and digital finance. Transactions involving BEP-20 tokens are settled in BNB, the native token of Binance Chain.
The Binance Chain — Binance’s original blockchain — also supports BEP-20 tokens. Both blockchains operate in parallel, enabling BEP-20 tokens to trade on Binance’s decentralized exchange (DEX).
What is Binance Smart Chain (BSC)?
BSC, or Binance Smart Chain, is Binance’s second blockchain. Launched in September 2020, it emerged as decentralized finance (DeFi) gained mainstream attention. Features like staking, decentralized lending, and other DeFi services were already available but lacked widespread adoption.
Binance introduced BSC as a development platform to attract users, talent, and projects. Today, BSC is considered Ethereum’s biggest competitor, with BEP-20 often compared to Ethereum’s ERC-20 standard.
BSC also enables users to create smart contracts, opening doors to dApps, DeFi, metaverse projects, and more.
Key Parameters of BEP-20 Tokens
BEP-20 includes several parameters that define its functionality:
- Blacklist: Blocks harmful addresses associated with the token standard.
- Can Mint: Serves as an inflationary parameter, allowing more tokens to be minted.
- Can Burn: Acts as a deflationary tool to reduce token supply by burning tokens.
- Can Pause: Temporarily halts token operations during attacks or platform issues.
Examples of BEP-20 Tokens
Many projects on BSC utilize BEP-20 tokens. Examples include:
- PancakeSwap: The largest DEX and automated market maker (AMM) on BSC.
- Autofarm: A popular yield aggregator built on BSC.
Users can acquire these tokens on Binance Exchange, Binance DEX, or PancakeSwap.
BEP-20 vs. ERC-20: A Comparison
While BEP-20 and ERC-20 serve similar purposes, they operate on different networks:
- ERC-20: Ethereum’s token standard.
- BEP-20: BSC’s token standard.
Both standards share basic functionalities like ownership, transfers, and token issuance. Binance Bridge allows interoperability between them, enabling token conversions without fees.

BEP-20 vs. BEP-2
BEP-2 is Binance Chain’s token standard, while BEP-20 belongs to BSC. Key differences:
- BEP-2: Used for Binance Chain (BNB Beacon Chain).
- BEP-20: Designed for Binance Smart Chain.
Both chains share BNB as their native asset and can exchange tokens via Binance Bridge. However, users must convert tokens to the respective standard for each chain.
Final Thoughts on BEP-20
BEP-20 is BSC’s token model, closely resembling Ethereum’s ERC-20. While some view Binance and Ethereum as competitors, compatibility remains crucial for Web3’s future.

Frequently Asked Questions (FAQs)
What is a BEP-20 address?
A BEP-20 address stores tokens on Binance Smart Chain. It starts with "0x," similar to Ethereum addresses.
Is BEP-20 the same as ERC-20?
No. BEP-20 runs on BSC, while ERC-20 operates on Ethereum. Tokens must be converted between chains.
What is a BEP-20 address in Binance?
It’s an address for receiving BEP-20 tokens. Always specify the network (BSC or Ethereum) when sharing your address.
Which wallets support BEP-20?
Wallets like OKX Wallet support BEP-20 tokens.
