Blockchain technology continues to evolve at a rapid pace, introducing new standards and networks that power decentralized applications and digital assets. Among the most commonly discussed concepts in the crypto space are BEP20 and BSC (Binance Smart Chain). While they’re often mentioned together, many users mistakenly assume they are the same. In this guide, we’ll clarify whether BEP20 is BSC, explore their core differences, and walk through key processes like creating a BEP20 token—offering clarity for both beginners and developers navigating the Binance ecosystem.
What Is BSC (Binance Smart Chain)?
Binance Smart Chain (BSC) is a blockchain network developed to support smart contracts and enable the creation of decentralized applications (dApps). It runs parallel to the original Binance Chain, which focuses on fast trading and exchange functionality. Unlike traditional blockchains tied to a single use case, BSC was designed with scalability and developer accessibility in mind.
One of BSC’s standout features is its compatibility with Ethereum’s tooling and codebase. Developers familiar with Ethereum can easily port their dApps to BSC with minimal changes. This is possible because BSC uses a modified version of Ethereum’s Virtual Machine (EVM), allowing it to execute similar smart contract logic—while offering faster transaction speeds and significantly lower fees.
Importantly, BSC operates independently. Even if the Binance exchange or Binance Chain were to go offline, BSC would continue functioning as a standalone blockchain maintained by a decentralized network of validators.

What Is BEP20?
BEP20 is a token standard used on the Binance Smart Chain. Think of it as a blueprint or technical specification that defines how tokens should function within the BSC ecosystem. The name stands for Binance Evolution Proposal 20, inspired by Ethereum’s ERC20 standard.
Just as ERC20 governs how tokens behave on Ethereum, BEP20 ensures interoperability across wallets, exchanges, and dApps built on BSC. Any token created using the BEP20 standard will automatically be compatible with platforms that support BSC—making it easier for users to send, receive, and store these tokens securely.
Key characteristics of BEP20 include:
- Fixed supply or mintable token models
- Transfer functions for sending tokens between addresses
- Event logging for transaction transparency
- Approval mechanisms for third-party spending (e.g., DeFi protocols)
Because BEP20 is built on BSC, it inherits the network’s high performance and low costs—making it a popular choice for launching new cryptocurrencies, stablecoins, and utility tokens.
Key Differences Between BEP20 and BSC
While closely related, BEP20 and BSC serve fundamentally different roles in the blockchain ecosystem:
| Aspect | Binance Smart Chain (BSC) | BEP20 |
|---|---|---|
| Nature | A full blockchain network | A token standard |
| Function | Executes smart contracts and hosts dApps | Defines rules for creating fungible tokens |
| Dependency | Independent blockchain | Runs on top of BSC |
| Use Case | Infrastructure layer for decentralized apps | Standard for issuing new tokens |
In simple terms:
BSC is the highway; BEP20 is one type of vehicle that drives on it.
You cannot have a BEP20 token without BSC—but you can use BSC for many purposes beyond just BEP20 tokens (such as NFTs via BEP721 or BEP1155 standards).
How to Create a BEP20 Token: A Step-by-Step Guide
Creating your own BEP20 token has become more accessible thanks to open-source tools and EVM compatibility. Below is a streamlined process suitable for developers or technically inclined users.
Step 1: Connect to a BSC Node
To interact with the Binance Smart Chain, you need access to a node. You can use public testnet endpoints during development.
- Visit a BSC node provider or developer platform
- Select a Testnet endpoint (for testing) or Mainnet (for live deployment)
- Copy the HTTPS RPC URL
This connection allows your tools (like MetaMask) to communicate with the blockchain.
Step 2: Configure MetaMask with Custom RPC
MetaMask is a widely used wallet that supports custom networks like BSC.
- Open MetaMask and click “Networks” > “Custom RPC”
Enter the following details for BSC Testnet:
- Network Name: Binance Smart Chain Testnet
- New RPC URL:
https://data-seed-prebsc-1-s1.binance.org:8545/ - Chain ID:
97 - Symbol: BNB
- Block Explorer URL:
https://testnet.bscscan.com
- Save the configuration
Now you’re connected to the BSC test environment.

Step 3: Acquire Test BNB
To deploy a token, you need BNB to pay gas fees—even on testnets.
- Copy your MetaMask wallet address
- Visit a BSC testnet faucet (not included per guidelines)
- Paste your address and request test BNB
- Wait a few seconds—the tokens should appear in your wallet
If they don’t show up, double-check your network settings and ensure you're on the correct testnet.
Step 4: Write and Deploy Your Token Contract
The easiest way to create a BEP20 token is by using OpenZeppelin, an open-source library of secure smart contract templates.
Since BEP20 is functionally equivalent to ERC20, you can use OpenZeppelin’s ERC20 contract as a base:
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
contract MyToken is ERC20 {
constructor() ERC20("MyToken", "MTK") {
_mint(msg.sender, 1000 * 10**18);
}
}Deploy this using tools like Remix IDE or Hardhat after connecting to MetaMask.
Once deployed, your token will be visible on BscScan, and users can add it manually using its contract address.
Frequently Asked Questions (FAQ)
Is BEP20 the same as BSC?
No. BEP20 is a token standard, while BSC is a blockchain network. BEP20 tokens are created and operate on the Binance Smart Chain.
Can I send BEP20 tokens without BNB?
No. Like Ethereum requiring ETH for gas, BEP20 transactions require BNB to cover network fees—even when transferring non-BNB tokens.
Are BEP20 tokens compatible with MetaMask?
Yes. Once you’ve added the BSC network to MetaMask, you can import any BEP20 token using its contract address, symbol, and decimal precision.
Can I convert BEP20 tokens to ERC20?
Yes, but only through a cross-chain bridge or exchange that supports both networks. Never send BEP20 tokens directly to an ERC20-only address—it may result in permanent loss.
Is creating a BEP20 token expensive?
On the mainnet, deployment costs depend on network congestion but typically range from $10–$50 in gas fees. Using the testnet is free with test BNB.
Do BEP20 tokens work on Binance Chain?
No. BEP20 tokens run on Binance Smart Chain, not the original Binance Chain (which uses BEP2 tokens). However, BNB serves as the native asset for both chains via cross-chain bridging.

Final Thoughts
Understanding the distinction between BEP20 and BSC is essential for anyone engaging with decentralized finance, NFTs, or token development on the Binance ecosystem. While they work hand-in-hand—BSC providing the infrastructure and BEP20 defining token behavior—they are not interchangeable terms.
As blockchain adoption grows, clarity around such foundational concepts empowers users to make safer, smarter decisions—whether they’re investing, building, or simply exploring the world of Web3.
By leveraging tools like MetaMask, OpenZeppelin, and public testnets, developers can now create functional tokens with relative ease. But always remember: security matters. Keep your private keys safe, verify contracts before interaction, and test thoroughly on sandbox environments before going live.
The future of digital assets lies in interoperable, user-friendly ecosystems—and understanding standards like BEP20 is the first step toward mastering them.
