How to Create a BEP-20 Token on BNB Chain

BEP-20 tokens are the foundation for transactions on BNB Chain. In this tutorial, you'll learn how to create and deploy a BEP-20 token to BNB Chain.

What Is a BEP-20 Token?

The BEP-20 token standard is a framework for creating fungible tokens on BNB Chain, built upon the ERC-20 standard. Both BEP-20 and ERC-20 tokens are interchangeable and homogeneous—meaning quantity matters more than uniqueness. Fiat currency is a perfect example: you care about how many dollars you have, not which specific dollar bills. Non-fungible items, by contrast, are unique and non-interchangeable.

What Is BNB Chain?

BNB Chain originated from a hard fork of the Go Ethereum (Geth) protocol. While it shares similarities with Ethereum, key differences exist, most notably its consensus mechanism. BNB Chain uses a Proof-of-Staked-Authority (PoSA) model with 21 validators rotating block production. These validators are supported by BNB holders staking the native token (BNB).

Advantages of BNB Chain

As an EVM-compatible network, BNB Chain allows developers to deploy the same smart contracts as Ethereum. Its PoS architecture offers:

• High speed and low transaction costs
• Scalability for decentralized applications (dApps)
• Energy efficiency compared to Proof-of-Work (PoW) chains

Bridging Assets to BNB Chain

To transfer assets from Ethereum to BNB Chain, use the Binance Bridge. This smart contract locks your Ethereum assets and mints a BEP-20 equivalent on BNB Chain after a short delay. Think of it like exchanging cash (ETH) for arcade tokens (ETH BEP-20)—usable within the BNB Chain ecosystem.

Prerequisites

To follow this guide, you'll need:

• Remix IDE: Web-based Solidity development environment.
• Brave Wallet (or MetaMask): For interacting with BNB Chain.
• BNB Chain Testnet: Deploy contracts without real funds.
• Testnet BNB: Obtain from the Binance Faucet.
• OpenZeppelin: Secure, audited smart contract libraries.

Connecting to BNB Chain Testnet

1. Network Name: Binance Testnet
2. RPC URL: https://bsc-dataseed.binance.org/
3. ChainID: 97
4. Currency Symbol: BNB
5. Block Explorer: https://testnet.bscscan.com

Building the BEP-20 Contract

Step 1: Set Up Remix IDE

Visit Remix and create a new file named BSCCoin.sol.

Step 2: Write the Contract Code

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract BSCCoin is ERC20 {
    constructor(uint256 initialSupply) ERC20("BSCCoin", "BSCC") {
        _mint(msg.sender, initialSupply * 10 ** decimals());
    }
}

Key Components:

• ERC20 Inheritance: Leverages OpenZeppelin’s audited ERC-20 standard.
• Constructor: Initializes token name (BSCCoin) and symbol (BSCC).
• Decimals: Defaults to 18 (like ETH), enabling decimal precision.

Step 3: Deploy the Contract

1. In Remix, select Injected Web3 as the environment.
2. Compile BSCCoin.sol.
3. Enter the initial token supply (e.g., 1000000) and click Deploy.
4. Confirm the transaction in your wallet (paying gas fees in testnet BNB).

Verifying the Deployment

1. Copy the contract address from Remix.
2. Paste it into BNB Testnet Explorer.
3. Confirm the token details under the BEP-20 Tokens tab.

Next Steps

• Mainnet Deployment: Repeat the process on BNB Chain Mainnet.
• Advanced Features: Add minting, burning, or governance using OpenZeppelin’s extensions.
• Integrate with DeFi: Use your token in liquidity pools or staking protocols.

FAQ

Q: What’s the difference between BEP-20 and ERC-20?

A: BEP-20 is native to BNB Chain, while ERC-20 is Ethereum’s standard. Both are fungible and interoperable via bridges.

Q: How do I get testnet BNB?

A: Use the Binance Faucet to request free testnet BNB.

Q: Can I deploy the same contract on Ethereum?

A: Yes! ERC-20 and BEP-20 contracts are nearly identical due to EVM compatibility.
