BNB Chain, originally known as Binance Smart Chain (BSC), is a blockchain platform developed by Binance. In February 2022, Binance merged its original Binance Chain (BC) with BSC to form the unified BNB Chain. This evolution created an EVM-compatible multi-chain ecosystem supporting smart contracts and decentralized applications (DApps), similar to Ethereum but with lower fees and faster transactions.
The native token of this ecosystem, BNB, plays a crucial role. It is used for paying transaction fees, participating in DApps, and governance. BNB also incorporates a coin-burn mechanism linked to its price and network usage, helping manage its supply.
When transferring assets, users must pay close attention to network types. BEP-2 and BEP-20 are not interchangeable—sending tokens to the wrong network can result in permanent loss.
What Is Binance Smart Chain (BSC)?
Binance Smart Chain (BSC) is a blockchain developed by Binance that operates alongside the original Binance Chain. Its key feature is support for smart contracts, enabling developers to build decentralized applications. Because it is compatible with the Ethereum Virtual Machine (EVM), many Ethereum-based DeFi projects have migrated their DApps to BSC.
Differences Between BSC and Binance Chain
While both blockchains were created by Binance, they serve different purposes. Binance Chain (BC) was designed primarily for fast trading, whereas BSC supports a broader range of decentralized functions, including smart contracts and DApps.
Key features of BSC include:
- EVM Compatibility: Developers can easily port Ethereum-based smart contracts to BSC.
- High Transaction Speed: BSC processes transactions in under 3 seconds, making it significantly faster than many older blockchains.
- Cross-Chain Compatibility: BSC and Binance Chain are interoperable, allowing users to transfer assets between them.
The Evolution to BNB Chain
In February 2022, Binance integrated Binance Chain and Binance Smart Chain into a single network called BNB Chain. This upgraded ecosystem enhances scalability and supports staking, governance, and multi-chain interoperability.
How to Use BNB Chain: Wallets
To interact with BNB Chain, you need a compatible wallet. Here are three popular options:
MetaMask
MetaMask is a widely used Ethereum wallet that can be configured to support BNB Chain via a simple network setup. Its browser extension offers a user-friendly interface for managing assets and executing transactions.
Trust Wallet
Trust Wallet is a mobile-based wallet that supports BNB Chain and many other blockchains. It offers built-in DApp connectivity and is ideal for users who prefer managing crypto on their phones.
Binance Chain Wallet
This browser extension wallet, developed by Binance, is specifically designed for the BNB Chain ecosystem. It supports both BEP-2 and BEP-20 tokens and integrates seamlessly with Binance services.
Funding Your BNB Chain Wallet
There are two primary ways to fund your BNB Chain wallet:
Via Binance Exchange
Users can withdraw tokens directly from Binance to their BNB Chain wallet. During withdrawal, ensure you select “BEP-20” as the network type to avoid errors.
Using the Binance Bridge
The Binance Bridge allows users to convert assets from other blockchains (like Ethereum or Tron) into BSC-compatible tokens. This is useful for users who hold assets outside the Binance ecosystem.
🔔 Important: BNB Chain uses the BEP-20 token standard, while the older Binance Chain uses BEP-2. Always confirm you are using the correct network type when transferring funds.
Transaction Fees on BNB Chain
BNB Chain fees are calculated based on Gas consumption:
Fee = Gas Used × Gas Price
Gas prices are denoted in Gwei, and Gas limits vary based on transaction complexity. A standard token transfer may require 21,000 Gas, while smart contract interactions can require more.
Thanks to its Proof of Staked Authority (PoSA) consensus mechanism, BNB Chain offers significantly lower fees than Ethereum. Most transactions cost less than $1, making it ideal for frequent users.

How to Check Transactions on BNB Chain
BscScan is the primary block explorer for BNB Chain. To review transaction details:
- Go to BscScan.
- Enter a wallet address or transaction hash.
- View balances, transaction history, token holdings, and smart contract interactions.
BscScan also supports advanced filtering for specific transaction types, such as BEP-20 transfers.
Understanding BEP-20 Tokens
BEP-20 is the technical standard for tokens on BNB Chain. It is similar to Ethereum’s ERC-20 standard and ensures compatibility between tokens and DApps.
Key features of BEP-20 tokens:
- Interoperability: Can be used across BNB Chain and Binance Chain.
- Low Fees: Cheaper transactions compared to ERC-20.
- High Efficiency: Fast block time enables quick confirmations.
Popular DApps on BNB Chain
BNB Chain hosts many decentralized applications. Here are some of the most widely used:
PancakeSwap
A leading decentralized exchange (DEX) on BNB Chain. Users swap tokens, provide liquidity, and farm yields. It also features lotteries, NFT integrations, and token launches.
Venus
A lending and borrowing protocol similar to Compound. Users can earn interest on deposits or mint synthetic stablecoins.
Autofarm
A yield optimization platform that automates staking across high-yield pools.
BurgerSwap
A decentralized automated market maker (AMM) for token swaps and liquidity provision.
Spartan Protocol
A platform for creating liquidity pools, synthetic assets, and decentralized loans.
Cream Finance
A cross-chain lending protocol originally launched on Ethereum but now also available on BNB Chain.
Frequently Asked Questions
What is the difference between BEP-2 and BEP-20?
BEP-2 is the token standard for the original Binance Chain, while BEP-20 is used on BNB Chain. They are not directly compatible—always use the correct network when transferring assets.
Can I recover tokens sent to the wrong network?
In most cases, tokens sent to an incompatible network are lost permanently. However, if you sent funds to an exchange, customer support may assist in recovering them. Always perform a test transaction first.
Why are fees lower on BNB Chain than on Ethereum?
BNB Chain uses a more efficient consensus mechanism (PoSA) and has a higher throughput, resulting in lower gas fees.
Is BNB Chain decentralized?
BNB Chain uses a proof-of-stake authority model, which is less decentralized than Ethereum but offers higher speed and lower costs.
How do I add BNB Chain to MetaMask?
You can add BNB Chain manually by entering the RPC details: Chain ID 56, symbol BNB, and block explorer URL https://bscscan.com.
What is BNB used for?
BNB is used for paying transaction fees, participating in token sales, staking, and governance within the BNB Chain ecosystem.
Avoiding Common Mistakes
To prevent loss of funds:
- Always confirm the network (BEP-20 or BEP-2) before transferring.
- Verify that the recipient address supports the token standard you are using.
- Start with a small test transaction.
If you send tokens to the wrong network, contact the receiving platform’s support team immediately with the transaction ID.
Conclusion
BNB Chain offers a high-speed, low-cost environment for decentralized applications. Its compatibility with Ethereum and growing ecosystem make it an attractive choice for developers and users. As the network continues to evolve, it is poised to play a significant role in the broader blockchain landscape.
