The early days of cryptocurrency were marked by complexity—launching a new token often meant building an entire blockchain from scratch or forking Bitcoin. That all changed with the rise of Ethereum, which transformed blockchain into a full-fledged development platform. Ethereum introduced the ERC-20 token standard, a blueprint that revolutionized how developers create and deploy digital assets.
As the crypto ecosystem evolved, new platforms emerged with their own tailored blockchain solutions. One of the most prominent is BNB Smart Chain (BSC), developed by Binance. It introduced its own token standard: BEP-20. Designed to support fast, low-cost transactions and decentralized applications (DApps), BEP-20 has become a cornerstone of the Binance ecosystem.
This guide dives deep into the BEP-20 token standard, explores its technical parameters, compares it with ERC-20, and explains its role in the broader blockchain landscape.
Understanding BEP-20: The Basics
BEP-20 is the primary token standard for the BNB Smart Chain (BSC)—a high-performance blockchain built to support smart contracts and decentralized finance (DeFi) applications. Functionally, BEP-20 mirrors Ethereum’s ERC-20 standard, making it familiar to developers and users alike.
The key advantage of BEP-20 lies in its accessibility. It allows developers to launch new tokens without needing deep blockchain expertise or building a new network. This ease of use has fueled the rapid growth of DeFi, GameFi, and yield farming projects on BSC.
All BEP-20 transactions require BNB as gas—the native token of the BNB Chain ecosystem. Whether you're swapping tokens on PancakeSwap or staking in a yield farm, BNB powers the network.
BEP-20 tokens are not just limited to utility—they also play a crucial role in tokenization, enabling real-world assets like stocks, commodities, or real estate to be represented digitally on the blockchain.

What Is BNB Smart Chain (BSC)?
Launched in September 2020, BNB Smart Chain (BSC) was Binance’s answer to Ethereum’s growing congestion and high gas fees. As decentralized finance (DeFi) gained traction, BSC offered a scalable alternative with faster transaction speeds and lower costs.
BSC supports smart contracts, enabling developers to build DApps across various sectors—including DeFi, NFTs, gaming, and metaverse projects. It operates alongside the BNB Beacon Chain (formerly Binance Chain), forming a dual-chain architecture:
- BNB Beacon Chain: Focused on governance and high-speed trading.
- BNB Smart Chain: Designed for smart contracts and DApp development.
This dual structure allows seamless interoperability between decentralized exchanges (DEXs) and DeFi protocols while maintaining network efficiency.
Key Parameters of the BEP-20 Standard
The BEP-20 standard includes several customizable parameters that enhance security and functionality:
- Blacklist: Enables the blocking of malicious addresses, adding a layer of protection against fraud or attacks.
- Can Mint: Allows additional tokens to be created, supporting inflationary models.
- Can Burn: Permits tokens to be permanently removed from circulation, helping control supply and potentially increase value.
- Can Pause: Lets administrators temporarily halt token transfers during emergencies—though this introduces a degree of centralization.
While features like "Can Pause" raise decentralization concerns, they can be crucial during security breaches or system upgrades.
Popular BEP-20 Tokens
Thousands of projects have launched BEP-20 tokens on BSC. Some notable examples include:
- CAKE (PancakeSwap): The native token of the largest DEX on BSC, used for staking, voting, and liquidity provision.
- AUTO (Autofarm): A yield optimizer that automates farming strategies across multiple DeFi platforms.
- BUSD (Binance USD): A now-retired stablecoin that was widely used across DeFi protocols.
These tokens can be traded on Binance Exchange, PancakeSwap, or stored in any BEP-20-compatible wallet.

BEP-20 vs ERC-20: What’s the Difference?
At their core, BEP-20 and ERC-20 serve the same purpose: they define rules for creating fungible tokens on their respective blockchains.
| Feature | BEP-20 (BNB Smart Chain) | ERC-20 (Ethereum) |
|---|---|---|
| Blockchain | BNB Smart Chain | Ethereum |
| Transaction Speed | ~3 seconds | ~15 seconds |
| Gas Fees | Low (paid in BNB) | High (paid in ETH) |
| Consensus Mechanism | Proof of Staked Authority | Proof of Stake |
Despite running on different networks, BEP-20 and ERC-20 are interoperable through cross-chain bridges. The Binance Bridge allows users to convert ERC-20 tokens into BEP-20 equivalents—and vice versa—enabling seamless asset transfers between Ethereum and BSC.
This process, known as "Peg-in," requires no fees and maintains asset value across chains. It has become a popular way for users to access lower-cost DeFi opportunities on BSC while retaining exposure to Ethereum-based projects.
BEP-20 vs BEP-2: Understanding the Relationship
While BEP-20 powers smart contracts on BSC, BEP-2 is the token standard used on the BNB Beacon Chain. Both standards coexist within the Binance ecosystem and are fully interoperable.
Key differences:
- BEP-2: Used primarily for governance and fast transactions on the original Binance Chain.
- BEP-20: Built for smart contracts and DeFi applications on BNB Smart Chain.
Users must convert between BEP-2 and BEP-20 tokens when switching chains—though this is easily done via the Binance Bridge. For example, sending BNB from a centralized exchange to a DeFi app requires converting BEP-2 to BEP-20.
The Future: BNB Chain Fusion
In early 2024, Binance announced BNB Chain Fusion, a major upgrade set to merge the BEP-2 and BEP-20 chains into a single unified network. This consolidation aims to:
- Improve security by reducing operational complexity.
- Enhance scalability and transaction efficiency.
- Simplify user experience across wallets and DApps.
As part of the transition, users must convert their BEP-2 and BEP-8 tokens to BEP-20 before April 2024 to ensure asset compatibility. After that date, legacy support will be limited.
This move signals Binance’s commitment to streamlining its infrastructure and strengthening its position in the Web3 ecosystem.

Frequently Asked Questions
What is a BEP-20 address?
A BEP-20 address is a wallet address capable of holding tokens on the BNB Smart Chain. Like Ethereum addresses, it starts with “0x” and supports smart contract interactions.
Is BEP-20 the same as ERC-20?
While functionally similar, BEP-20 runs on BNB Smart Chain, whereas ERC-20 operates on Ethereum. Tokens must be converted between standards to move across chains.
Can I use a BEP-20 wallet for other tokens?
Yes—most modern Web3 wallets (like OKX Wallet) support multiple chains and standards, including BEP-20, ERC-20, and more.
Are BEP-20 transactions secure?
Yes. Transactions are secured by BSC’s consensus mechanism and protected by cryptographic verification. However, always verify contract addresses to avoid scams.
How do I get BEP-20 tokens?
You can purchase them on exchanges like Binance or acquire them through DeFi platforms such as PancakeSwap. Always ensure you’re using the correct network when transferring funds.
What happens to BEP-2 after BNB Chain Fusion?
After fusion, BEP-2 will be phased out. Users must migrate their assets to BEP-20 to remain compatible with the unified chain.
Final Thoughts
BEP-20 has emerged as a powerful alternative to ERC-20, offering developers and users a scalable, cost-effective environment for building and interacting with decentralized applications. While it shares many similarities with Ethereum’s standard, its integration with the Binance ecosystem gives it unique advantages in speed, accessibility, and cross-chain functionality.
With the upcoming BNB Chain Fusion, Binance is paving the way for a more unified, efficient blockchain infrastructure. As interoperability becomes increasingly vital in Web3, standards like BEP-20 will continue to play a central role in connecting ecosystems and driving innovation.
Whether you're launching a token, exploring DeFi, or managing digital assets, understanding BEP-20 is essential for navigating today’s multi-chain world.
