The world of cryptocurrency has evolved dramatically since its early days, when creating a new token meant either launching an entirely new blockchain or forking Bitcoin’s codebase—a complex and resource-intensive process. The game changed with Ethereum, which transformed blockchain into a programmable platform. Its introduction of the ERC-20 token standard provided a universal blueprint, enabling developers to launch tokens quickly and efficiently.
As the ecosystem expanded, new blockchains emerged to meet growing demands for speed, scalability, and lower costs. Among them, BNB Smart Chain (BSC) rose as a powerful alternative, introducing its own token standard: BEP-20. Designed to mirror the functionality of ERC-20 while operating within Binance’s high-performance network, BEP-20 has become a cornerstone of decentralized finance (DeFi), gaming, and tokenization.
This guide dives deep into what BEP-20 is, how it works, and why it matters in today’s blockchain landscape.
Understanding BEP-20: The BSC Equivalent of ERC-20
BEP-20 is the primary token standard on BNB Smart Chain (BSC), formerly known as Binance Smart Chain. It serves the same role as ERC-20 does on Ethereum—acting as a technical framework that defines how tokens are created, transferred, and managed on the network.
Because BSC was designed to be EVM-compatible (Ethereum Virtual Machine), BEP-20 inherits much of ERC-20’s structure. This compatibility allows developers familiar with Ethereum to easily deploy projects on BSC with minimal adjustments.
One of the biggest advantages of BEP-20 is accessibility. Creating a BEP-20 token doesn’t require deep programming expertise or building a new blockchain from scratch. Instead, developers can use pre-defined templates and tools to launch utility tokens, governance tokens, or even stablecoins in a matter of minutes.

BEP-20 tokens are widely used across DeFi platforms, decentralized exchanges (DEXs), and NFT marketplaces built on BSC. They also play a crucial role in tokenization, bridging traditional financial assets with blockchain technology by representing real-world value in digital form.
All transactions involving BEP-20 tokens require BNB as gas—making BNB not only the native coin of the BNB ecosystem but also essential for network operations.
What Is BNB Smart Chain (BSC)?
Launched in September 2020, BNB Smart Chain (BSC) was Binance’s answer to Ethereum’s rising congestion and high transaction fees. While Binance already had the BNB Beacon Chain (formerly Binance Chain) for fast trading and governance, BSC added smart contract capabilities to support decentralized applications (DApps).
BSC runs parallel to the Beacon Chain but focuses on smart contracts, DeFi, GameFi, and metaverse projects. Thanks to its consensus mechanism—Proof of Staked Authority (PoSA)—BSC offers faster block times and lower fees than Ethereum, making it attractive for both users and developers.
Today, BSC ranks among the most active blockchain networks globally, hosting thousands of DApps and rivaling Ethereum in terms of DeFi volume.
Key Features and Parameters of BEP-20
The BEP-20 standard includes several customizable parameters that enhance functionality and security:
- Blacklist: Allows token creators to block malicious addresses from interacting with the token—useful for regulatory compliance or fraud prevention.
- Can Mint: Enables the creation of new tokens after deployment, allowing for inflationary models or team allocations.
- Can Burn: Permits token holders or contract owners to permanently destroy tokens, reducing supply to increase scarcity and potentially drive up value.
- Can Pause: Gives administrators the ability to temporarily halt token transfers during emergencies or upgrades—though this introduces a degree of centralization.
These features provide flexibility but should be used responsibly to maintain trust in decentralized ecosystems.
Real-World Examples of BEP-20 Tokens
Thousands of projects leverage BEP-20 for their tokens. Notable examples include:
- CAKE (PancakeSwap): The native token of the largest DEX on BSC, used for staking, voting, and yield farming.
- AUTO (Autofarm): A yield optimization platform that automates DeFi strategies across multiple protocols.
- USDT and USDC (BEP-20 versions): Stablecoins pegged to the US dollar, widely used for trading and hedging volatility.
These tokens can be traded on Binance, PancakeSwap, or stored in any BEP-20-compatible wallet.

BEP-20 vs. ERC-20: What’s the Difference?
While both standards serve similar purposes, key differences lie in performance and ecosystem:
| Aspect | BEP-20 (BSC) | ERC-20 (Ethereum) |
|---|---|---|
| Transaction Speed | ~3 seconds | ~15 seconds |
| Gas Fees | Low (fractions of a cent) | High (can exceed $10 during peak times) |
| Consensus | Proof of Staked Authority (PoSA) | Proof of Stake (PoS) |
| Ecosystem Focus | High-throughput DeFi, GameFi | Mature DeFi, NFTs, Enterprise |
Despite running on different chains, interoperability is seamless thanks to cross-chain bridges like BNB Bridge. Users can convert ERC-20 tokens to BEP-20 (and vice versa) without fees—a process known as Peg-in/Peg-out.
This interoperability strengthens the broader Web3 vision: a connected, multi-chain future where assets flow freely across networks.
BEP-20 vs. BEP-2: Two Standards Under One Ecosystem
Within Binance’s infrastructure, two main token standards coexist:
- BEP-2: Used on BNB Beacon Chain, primarily for exchange-based transactions and governance.
- BEP-20: Used on BNB Smart Chain, supporting smart contracts and DApps.
Both chains share BNB as their native asset and are interoperable via the Binance Bridge. However, they serve different functions:
- Use BEP-2 for fast trades on Binance DEX.
- Use BEP-20 for DeFi participation, staking, or interacting with DApps.
Tokens must be converted between formats depending on the target chain—ensuring optimal performance and use-case alignment.
Introducing BNB Chain Fusion
In a major upgrade announced in January 2025, Binance unveiled BNB Chain Fusion, set to unify the BEP-2 and BEP-8 chains under the BEP-20 standard by April 2025.
This consolidation aims to:
- Improve security by eliminating vulnerabilities from maintaining dual chains.
- Enhance efficiency through simplified architecture.
- Reduce user confusion around token standards.
As part of the transition, users must convert their BEP-2 and BEP-8 assets to BEP-20 before the deadline. Late migrations will still be possible via command-line tools, but early action is strongly encouraged.
This move signals Binance’s commitment to streamlining blockchain operations and advancing toward a more cohesive Web3 infrastructure.

Frequently Asked Questions (FAQs)
What is a BEP-20 address?
A BEP-20 address is a wallet address that supports tokens on the BNB Smart Chain. It typically starts with "0x" and is compatible with EVM-based networks like Ethereum and Polygon.
Is BEP-20 the same as ERC-20?
Functionally, yes—both define how tokens behave. However, BEP-20 operates on BNB Smart Chain, while ERC-20 runs on Ethereum. They are interoperable via bridges but are not natively interchangeable.
Can I send BEP-20 tokens to an ERC-20 address?
No—sending directly will result in lost funds. Always ensure you're using the correct network when transferring tokens. Use a cross-chain bridge to convert between standards safely.
Do BEP-20 tokens have gas fees?
Yes, all BEP-20 transactions require BNB to cover gas fees. These fees are significantly lower than those on Ethereum.
What is a BEP-20-compliant wallet?
A wallet that supports BNB Smart Chain and can store, send, and receive BEP-20 tokens. Examples include Trust Wallet, MetaMask (with custom network setup), and OKX Web3 Wallet.
Why choose BEP-20 over other token standards?
BEP-20 offers low fees, fast transactions, strong developer support, and seamless integration with leading DeFi platforms—making it ideal for everyday use and scalable applications.
Final Thoughts
BEP-20 has emerged as one of the most practical and widely adopted token standards in modern blockchain development. By combining the proven design of ERC-20 with BSC’s high-speed, low-cost infrastructure, it empowers innovators to build accessible, scalable solutions in DeFi, gaming, and beyond.
As BNB Chain Fusion reshapes the ecosystem toward greater unity and efficiency, now is an excellent time to understand—and engage with—the power of BEP-20 tokens.
