In the early days of cryptocurrency, launching a new token was a daunting challenge. It often required building an entirely new blockchain or forking Bitcoin’s codebase—both complex and resource-intensive processes. That changed with Ethereum’s rise, which transformed blockchain into a versatile development platform. The introduction of the ERC-20 token standard provided a clear, reusable blueprint for creating new digital assets, sparking a wave of innovation.
As the ecosystem evolved, new blockchains emerged with their own enhancements and optimizations. One standout is BNB Smart Chain (BSC), which introduced BEP-20, its native token standard designed to mirror ERC-20 while offering faster transactions and lower fees. This guide dives into what BEP-20 is, how it works, and why it matters in today’s decentralized landscape.
Understanding BEP-20: The BSC Token Standard
BEP-20 is the primary token standard on BNB Smart Chain (BSC)—formerly known as Binance Smart Chain. Functionally equivalent to Ethereum’s ERC-20, BEP-20 defines a set of rules that tokens must follow to ensure compatibility across wallets, exchanges, and decentralized applications (DApps).
This standard enables developers to create new tokens without building a blockchain from scratch. Whether launching utility tokens, governance assets, or digital representations of real-world assets, BEP-20 streamlines the process with minimal coding overhead.
One key feature of BEP-20 is its seamless integration with BSC’s smart contract ecosystem. This makes it ideal for projects in DeFi (decentralized finance), GameFi, and NFTs, where fast and low-cost transactions are crucial. All BEP-20 transactions are paid in BNB, the native cryptocurrency of the BNB Chain ecosystem.

Notably, BEP-20 tokens aren’t limited to BSC alone. Thanks to cross-chain bridges like BNB Bridge, they can be transferred between networks—such as from Ethereum (ERC-20) to BSC (BEP-20)—enabling greater liquidity and interoperability.
What Is BNB Smart Chain?
Launched in September 2020, BNB Smart Chain (BSC) was Binance’s answer to Ethereum’s scalability challenges. While Ethereum struggled with high gas fees and slow confirmation times during peak usage, BSC offered a more efficient alternative using a Proof-of-Staked-Authority (PoSA) consensus mechanism.
BSC runs in parallel with BNB Beacon Chain (formerly Binance Chain), forming a dual-chain architecture:
- BNB Beacon Chain: Focuses on decentralized exchange (DEX) operations and governance.
- BNB Smart Chain: Enables smart contracts, DApps, and DeFi innovations.
This structure allows users to enjoy both high-speed trading and robust programmability. Today, BSC ranks among the most active blockchains globally, hosting thousands of DApps and serving as a major hub for yield farming, staking, and decentralized exchanges like PancakeSwap.
Key Parameters of the BEP-20 Standard
The BEP-20 standard includes several optional parameters that enhance functionality and security:
🔒 Blacklist
Allows project teams to block malicious addresses from interacting with the token. While this improves security, it introduces a degree of centralization—a topic of debate in the crypto community.
🔄 Can Mint
Enables the creation of new tokens after deployment, increasing supply. This inflationary mechanism is useful for reward systems or ecosystem growth.
🧯 Can Burn
Permits the permanent removal of tokens from circulation, reducing supply. Burning is often used to increase scarcity and potentially boost value.
⏸️ Can Pause
Gives developers the ability to temporarily halt token transfers during emergencies or attacks. Though powerful, this feature raises decentralization concerns due to centralized control.
These parameters make BEP-20 flexible and developer-friendly, allowing tailored solutions for different use cases.
Popular BEP-20 Tokens
The BSC ecosystem hosts a wide range of BEP-20 tokens powering innovative projects:
- CAKE (PancakeSwap): The native token of the largest DEX on BSC, used for staking, governance, and yield farming.
- AUTO (Autofarm): A yield optimization platform that automates profit generation across multiple DeFi protocols.
- VENUS (XVS): A decentralized lending and borrowing protocol with algorithmic interest rates.
These tokens—and hundreds more—can be traded on Binance, 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 identical purposes: they define how fungible tokens behave on their respective blockchains. Both support basic functions like:
- Transferring tokens
- Checking balances
- Approving third-party spending
However, key differences lie in performance and cost:
| Feature | BEP-20 (BSC) | ERC-20 (Ethereum) |
|---|---|---|
| Transaction Speed | ~3 seconds | ~15 seconds |
| Transaction Cost | Fraction of a cent | Often $1–$5+ |
| Consensus Mechanism | PoSA (faster finality) | PoW/PoS (more decentralized) |
Despite running on different networks, they are interoperable via cross-chain bridges. Using 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 compatibility ensures liquidity flows freely between ecosystems, fostering collaboration over competition.
BEP-20 vs. BEP-2: Two Standards, One Ecosystem
While BEP-20 operates on BNB Smart Chain, BEP-2 is the token standard for BNB Beacon Chain. Here's how they compare:
- BEP-2: Used primarily for fast trading on Binance DEX; supports fewer features but offers rapid settlement.
- BEP-20: Full smart contract support; ideal for DeFi, NFTs, and complex DApps.
Though distinct, both standards coexist within the broader BNB Chain ecosystem and share BNB as their native asset. Cross-chain tools allow easy conversion between them.
However, users must ensure they send tokens via the correct network—sending BEP-2 tokens to a BEP-20 address (or vice versa) without conversion may result in loss of funds.
Introducing BNB Chain Fusion
In April 2024, Binance completed BNB Chain Fusion, merging BNB Beacon Chain and BNB Smart Chain into a unified network. This upgrade aims to:
- Improve security by eliminating vulnerabilities from maintaining two separate chains
- Enhance efficiency through streamlined consensus
- Simplify user experience with a single token standard
As part of this transition:
- BEP-2 and BEP-8 tokens were migrated to BEP-20
- Legacy chains were deprecated
- Cross-chain operations were consolidated
Users who didn’t migrate before the deadline can still recover assets via command-line tools, though support is limited.
This fusion marks a pivotal step toward a more cohesive, scalable blockchain infrastructure.
Frequently Asked Questions (FAQs)
What is a BEP-20 address?
A BEP-20 address is a wallet address on BNB Smart Chain capable of holding BEP-20 tokens. It typically starts with “0x,” similar to Ethereum addresses. Always confirm the network when sending funds to avoid errors.
Is BEP-20 the same as ERC-20?
Functionally, yes—both are token standards for fungible tokens. However, BEP-20 runs on BNB Smart Chain and offers faster speeds and lower fees than ERC-20 on Ethereum.
Can I store BEP-20 tokens in any wallet?
Only wallets that support BSC/BEP-20 can hold these tokens. Examples include Trust Wallet, MetaMask (with BSC network added), and OKX Web3 Wallet.
Do I need BNB to use BEP-20 tokens?
Yes. All transactions involving BEP-20 tokens require BNB to cover gas fees, regardless of the token being transferred.
How do I convert ERC-20 to BEP-20?
Use a cross-chain bridge like BNB Bridge or supported exchanges. The process involves locking your ERC-20 token and minting an equivalent BEP-20 version on BSC—free of charge.
Why did Binance merge its chains?
To improve security, reduce complexity, and unify development under one efficient network. The fusion eliminates redundancies and strengthens long-term sustainability.
Final Thoughts
BEP-20 has become a cornerstone of the modern blockchain landscape. By offering a reliable, scalable alternative to ERC-20, it empowers developers and users alike to build and participate in decentralized ecosystems with ease.
While debates about chain rivalry persist, the future lies in interoperability and collaboration. With tools like cross-chain bridges and unified architectures like BNB Chain Fusion, the industry is moving toward seamless connectivity—where value and innovation flow freely across platforms.
Whether you're launching a project or investing in DeFi, understanding BEP-20 is essential for navigating today’s dynamic crypto environment.
