BNB Coin, originally known as Binance Coin, is the native cryptocurrency of the BNB Smart Chain ecosystem. It serves multiple purposes, including paying transaction fees, participating in governance, and enabling utility across the Binance network. This guide explains what BNB is, how it works, and how you can use it effectively.
Understanding BNB Coin
BNB is the fundamental utility token within the BNB Chain ecosystem, which includes BNB Smart Chain (BSC) and BNB Beacon Chain. It was rebranded in 2022 to mean "Build and Build," reflecting its expanded role beyond the Binance exchange.
As a gas token, BNB is used to pay for transaction fees and smart contract executions on BNB Smart Chain. It also offers holders governance rights, allowing them to participate in key network decisions. Additionally, BNB provides users with transaction fee discounts on the Binance centralized exchange and acts as collateral in various financial applications.
BNB Smart Chain is a high-performance blockchain compatible with the Ethereum Virtual Machine (EVM). This compatibility allows developers to port Ethereum-based applications to BSC with minimal changes, benefiting from lower costs and faster transaction speeds.
How BNB Smart Chain Works
BNB Smart Chain operates on a consensus mechanism combining Delegated Proof-of-Stake (DPoS) and Proof-of-Authority (PoA). This hybrid model ensures efficiency and decentralization by limiting the number of validators.
Key features of BNB Smart Chain include:
- Fast Block Time: Blocks are produced every 3 seconds, enabling quick transaction confirmations.
- EVM Compatibility: Supports Ethereum-based smart contracts and dApps.
- Low Transaction Costs: Significantly cheaper than Ethereum mainnet.
- Validator Incentives: Validators earn fees from smart contract executions instead of block rewards.
The network relies on BNB for staking, governance, and transaction fees. Its design focuses on scalability without compromising security.
History of BNB and BNB Smart Chain
BNB was launched in 2017 as an ERC-20 token on Ethereum. In 2019, it migrated to Binance Chain, the exchange's native blockchain. BNB Smart Chain debuted in September 2020, addressing Ethereum's scalability issues during the DeFi boom.
In February 2022, Binance Smart Chain was rebranded to BNB Smart Chain. It now belongs to the broader BNB Chain ecosystem, which includes:
- BNB Beacon Chain (staking and governance)
- BNB Smart Chain (smart contract layer)
- ZkBNB (zero-knowledge proof layer)
- BNB Greenfield (decentralized data storage)
How to Create a BNB Smart Chain Wallet
Creating a wallet for BNB Smart Chain is straightforward. You can use software wallets like MetaMask or hardware wallets for enhanced security. Follow these steps:
- Choose a Wallet: Select a compatible wallet supporting BEP-20 tokens.
- Set Up Security: Write down your seed phrase and store it offline.
- Add BNB Smart Chain Network: Configure your wallet with BSC’s RPC details.
- Fund Your Wallet: Transfer BNB tokens to your address to start transacting.
Always verify official sources to avoid phishing scams.
Using BNB and BNB Smart Chain
BNB tokens can be used for various purposes:
- Paying Fees: Cover transaction and smart contract costs on BSC.
- Staking and Governance: Participate in network validation and voting.
- Trading and Discounts: Enjoy reduced fees on Binance exchange.
- DeFi Applications: Supply liquidity, lend, borrow, and yield farm.

Bridging Between BNB Smart Chain and Ethereum
You can transfer assets between Ethereum and BNB Smart Chain using bridges like Celer cBridge. Bridging enables you to use Ethereum-based assets on BSC’s low-fee environment. The process involves:
- Selecting the asset and amount to bridge.
- Approving the transaction on the source chain.
- Waiting for confirmations before accessing funds on the destination chain.
Bridged assets can be used in DeFi protocols for swapping, lending, or providing liquidity.
Frequently Asked Questions
What is the difference between BNB and BSC?
BNB is the native cryptocurrency, while BSC is the blockchain network. BNB is used for transactions, staking, and governance on BSC.
Can I use MetaMask for BNB Smart Chain?
Yes, MetaMask supports BSC. You need to add BSC as a custom network using the correct RPC settings.
Is BNB Smart Chain secure?

How do I avoid high gas fees?
BSC offers lower fees than Ethereum. For even better efficiency, time your transactions during off-peak hours.
What are the risks of bridging assets?
Bridging involves smart contract risks and potential delays. Use reputable bridges and verify transaction details carefully.
Can I stake BNB tokens?
Yes, you can stake BNB to participate in network validation or through exchange-based earning programs.
