The BEP-20 token standard plays a pivotal role in the world of blockchain and decentralized applications. As a foundational protocol on the Binance Smart Chain (BSC), it enables developers to create and deploy digital tokens efficiently, securely, and with broad compatibility. Whether you're new to cryptocurrency or expanding your blockchain development skills, understanding BEP-20 is essential for navigating today’s fast-evolving Web3 landscape.
This guide explores the core aspects of BEP-20, how it compares to other standards like BEP-2 and ERC-20, and why it matters for users and developers alike.
What Is BEP-20?
BEP-20 stands for Binance Evolution Proposal 20, a technical specification that defines the rules for creating fungible tokens on the Binance Smart Chain. It acts as a blueprint, ensuring all tokens built under this standard follow consistent behaviors — such as how they’re transferred, how balances are tracked, and how total supply is managed.
Think of BEP-20 as a set of programming guidelines that ensure interoperability across wallets, exchanges, and decentralized applications (dApps). Any token issued using the BEP-20 standard can seamlessly interact with other BEP-20-compliant services within the BSC ecosystem.

Key Features of BEP-20
- Fungibility: Each token is interchangeable with another of the same type.
- Transferability: Tokens can be sent between addresses following standardized functions.
- Divisibility: Like most crypto assets, BEP-20 tokens can be divided into smaller units (down to 18 decimal places).
- Total Supply Control: The maximum number of tokens is defined at launch and can be fixed or programmatically adjusted.
- Smart Contract Compatibility: Built on BSC’s EVM (Ethereum Virtual Machine)-compatible environment, making deployment straightforward for Ethereum developers.
Developers benefit from BEP-20’s simplicity and flexibility. Because it mirrors the widely adopted ERC-20 standard used on Ethereum, many tools, libraries, and development frameworks work out-of-the-box when building on BSC.
How Does BEP-20 Work?
At its core, a BEP-20 token operates through a smart contract deployed on the Binance Smart Chain. This contract includes mandatory functions such as:
transfer()– Sends tokens from one address to another.approve()– Allows a third party to spend tokens on behalf of the owner.allowance()– Checks how many tokens an address is permitted to spend.balanceOf()– Returns the token balance of a specific address.totalSupply()– Reveals the overall circulating supply.
These functions ensure predictable behavior across platforms, enabling smooth integration with decentralized exchanges (DEXs), lending protocols, NFT marketplaces, and more.
All transactions involving BEP-20 tokens require BNB (Binance Coin) to pay gas fees — similar to how ETH powers transactions on Ethereum. This dual-token model keeps the network secure while allowing custom tokens to focus on utility rather than transaction validation.
BEP-2 vs BEP-20: Understanding the Difference
While both standards exist within Binance's ecosystem, BEP-2 and BEP-20 serve different chains and purposes.
| Feature | BEP-2 | BEP-20 |
|---|---|---|
| Chain | BNB Beacon Chain (formerly Binance Chain) | Binance Smart Chain (BSC) |
| Purpose | High-speed trading and asset issuance | Smart contracts and dApp development |
| Functionality | Limited to transfers | Supports complex logic via smart contracts |
| Gas Currency | BNB | BNB |
BEP-2 was designed for speed and efficiency in trading environments, powering the original Binance Chain. In contrast, BEP-20 supports advanced functionality like staking, yield farming, and automated market makers (AMMs), thanks to BSC’s support for smart contracts.
Despite their differences, these two standards are fully interoperable through Binance’s cross-chain bridge system. Users can freely convert BEP-2 tokens into BEP-20 tokens (and vice versa) using simple swap mechanisms provided by Binance or third-party tools.
This interoperability ensures liquidity flows smoothly across both chains, combining high performance with programmability.
Why BEP-20 Matters for Developers and Users
For developers, BEP-20 offers a low-barrier entry point into blockchain development. With minimal code changes, an existing ERC-20 project can be ported to BSC, benefiting from:
- Lower transaction fees
- Faster block times (~3 seconds)
- Large user base and exchange support
For users, BEP-20 means access to a wide array of decentralized finance (DeFi) applications — including lending platforms, prediction markets, and gaming ecosystems — all operating with affordable and fast transactions.
Popular BEP-20 tokens include:
- CAKE (PancakeSwap): Used for staking, voting, and farming rewards
- BAKE (BakerySwap): Governance and incentive token
- USDT (BEP-20 version): Stablecoin used for trading and payments
These tokens power real-world use cases across DeFi, NFTs, metaverse projects, and play-to-earn games.

Is BEP-20 Compatible With ERC-20?
Yes — BEP-20 is fully compatible with ERC-20 in terms of interface design and function structure. This means:
- Ethereum-based tools (like MetaMask, Hardhat, Truffle) work seamlessly with BSC.
- Developers familiar with Solidity can easily deploy BEP-20 tokens.
- Cross-chain bridges allow ERC-20 tokens to be wrapped and used on BSC as BEP-20 equivalents.
For example, “WETH” (Wrapped Ether) exists on BSC as a BEP-20 token, enabling Ethereum assets to participate in Binance’s DeFi ecosystem without leaving their original chain permanently.
This compatibility has driven massive adoption, making BSC one of the most active blockchains outside Ethereum.
Frequently Asked Questions (FAQ)
What is the main purpose of the BEP-20 standard?
The primary goal of BEP-20 is to provide a reliable, efficient framework for launching tokens on the Binance Smart Chain. It enables developers to create digital assets that support DeFi applications, governance models, loyalty programs, and more — all with low cost and high speed.
Can I store BEP-20 tokens in any wallet?
You can store BEP-20 tokens in any wallet that supports the Binance Smart Chain, such as Trust Wallet, MetaMask, or Ledger (when manually configured). Always ensure your wallet is connected to the correct network to avoid lost funds.
How do I send BEP-20 tokens safely?
To send BEP-20 tokens:
- Confirm the recipient address accepts BEP-20 tokens.
- Use a wallet connected to the BSC network.
- Keep enough BNB in your wallet to cover gas fees.
- Double-check the contract address if adding a custom token.

Are BEP-20 tokens secure?
Security depends on the implementation. While the standard itself is robust, poorly coded contracts may contain vulnerabilities. Always audit or research a token’s smart contract before interacting with it.
Can I convert ERC-20 tokens to BEP-20?
Yes, through cross-chain bridges like the Binance Bridge or third-party services. These wrap your ERC-20 token into a BEP-20 version that mirrors its value and functionality on BSC.
Is BNB a BEP-20 token?
No. BNB is the native coin of both BNB Beacon Chain (as BEP-2) and Binance Smart Chain (as BEP-20). On BSC, it functions similarly to ETH on Ethereum — used primarily for gas fees and staking.
Final Thoughts
The BEP-20 standard has become a cornerstone of the Binance Smart Chain ecosystem, empowering thousands of projects to launch quickly and scale efficiently. Its compatibility with Ethereum’s ERC-20 standard lowers development barriers, while its low-cost infrastructure attracts millions of users worldwide.
As blockchain technology evolves, standards like BEP-20 will continue shaping how we build and interact with digital economies — from decentralized finance to social platforms and beyond.
Whether you're investing in tokens, building dApps, or simply exploring crypto, understanding BEP-20 gives you a crucial advantage in navigating the future of finance.
