In the fast-evolving world of cryptocurrency, it's easy to get confused—especially when platforms evolve and introduce new blockchain networks. If you're not deeply involved in the Binance ecosystem, you might be puzzled by terms like Binance Chain and Binance Smart Chain. With similar logos and overlapping names, particularly in wallets like TokenPocket (TP), distinguishing between them can be tricky. More importantly, knowing where to send your BNB—whether via BEP2 or BEP20—is crucial to avoid losing funds.
This guide breaks down the key differences between Binance Chain and Binance Smart Chain, explains why both exist, and walks you through how to correctly withdraw BNB to the Binance Smart Chain (BSC).
Understanding Binance Chain vs. Binance Smart Chain
Launched in April 2019, Binance Chain (BC) was designed primarily to power Binance DEX—the decentralized exchange under the Binance umbrella. Built for speed and efficiency, it supports high-throughput transactions with a robust matching engine ideal for trading. However, its architecture is relatively rigid.
While excellent for fast peer-to-peer trades, Binance Chain lacks support for complex smart contracts and decentralized applications (DApps). Running advanced logic on BC could slow down transaction processing and compromise the stability of Binance DEX.
To address these limitations, Binance introduced Binance Smart Chain (BSC) in September 2020—a parallel blockchain focused on smart contract functionality. Unlike Binance Chain, BSC is fully compatible with Ethereum Virtual Machine (EVM), meaning it supports Ethereum-style smart contracts and allows developers to easily port DApps from Ethereum with minimal changes.

Though separate, the two chains are interconnected through a cross-chain communication protocol built into their core. This enables asset transfers between chains using a bridge mechanism, with BNB serving as the native token on both networks.
Key Differences: Binance Chain (BEP2) vs. Binance Smart Chain (BEP20)
| Feature | Binance Chain (BC) | Binance Smart Chain (BSC) |
|---|---|---|
| Consensus Mechanism | Tendermint-based PoS | Proof-of-Staked-Authority (PoSA) |
| Smart Contract Support | No | Yes |
| EVM Compatible | No | Yes |
| Primary Use Case | Decentralized Exchange (DEX) | DeFi, DApps, Staking |
| Token Standard | BEP2 | BEP20 |
| Transaction Speed | ~1 second | ~3 seconds |
| Gas Fees | Paid in BNB (BEP2) | Paid in BNB (BEP20) |
The most important takeaway? BEP2 tokens operate on Binance Chain, while BEP20 tokens run on Binance Smart Chain.
You cannot directly transfer BEP2 assets to a BEP20 address—or vice versa—without using a cross-chain bridge. Attempting to do so may result in permanent loss of funds.
Why Does This Matter When Withdrawing BNB?
When withdrawing BNB from an exchange like Binance, you’ll often see multiple network options:
- BEP2 (Binance Chain)
- BEP20 (Binance Smart Chain)
Choosing the wrong one can lead to delayed or lost deposits. For example:
- If you select BEP2 but your wallet only supports BEP20, the transaction might not be recognized.
- If you send BEP20 BNB to a BEP2-only address, recovery becomes extremely difficult.
Most modern wallets—including Trust Wallet, MetaMask, and TokenPocket—support BEP20 via Binance Smart Chain, thanks to its EVM compatibility and booming DeFi ecosystem.
So unless you're specifically interacting with Binance DEX, always choose BEP20 (BSC) when withdrawing BNB.
Step-by-Step: How to Withdraw BNB to Binance Smart Chain (BSC)
Follow these steps to safely transfer your BNB from a centralized exchange to your personal wallet using the BEP20 (BSC) network:
- Open your wallet app (e.g., TokenPocket or Trust Wallet).
- Navigate to your BNB wallet.
- Copy the wallet address (it should start with
0x, just like Ethereum addresses). - Go to your exchange platform (e.g., Binance).
- Click “Withdraw” next to your BNB balance.
- Paste the copied address into the recipient field.
Select the withdrawal network: Choose “BEP20 (Binance Smart Chain)”.
- ⚠️ Do NOT select “BEP2” unless explicitly required.
- Enter the amount and confirm the transaction.
- Wait for confirmation (usually within 3–5 minutes).
Once completed, your BNB will appear in your wallet and can be used for:
- Paying low gas fees on BSC
- Participating in DeFi protocols (e.g., PancakeSwap)
- Staking or yield farming
- Interacting with NFT marketplaces

Common FAQs About Withdrawing BNB to BSC
Q: Can I use the same address for BEP2 and BEP20?
A: Yes—many wallets generate a single address that supports both BEP2 and BEP20. However, always verify which network you're using during withdrawal.
Q: What happens if I send BEP2 to a BEP20 address?
A: Since both chains are separate, sending BEP2 tokens to a BEP20 address without bridging may result in loss of funds. Always double-check the network before confirming.
Q: Is there a fee difference between BEP2 and BEP20 withdrawals?
A: BEP20 fees vary slightly based on network congestion but are generally low (~$0.10). BEP2 fees are fixed and paid in BNB.
Q: Can I bridge BEP2 BNB to BEP20?
A: Yes—use the official Binance Bridge to convert BEP2 BNB into BEP20 format securely.
Q: Why does my wallet show a 0x address for BNB?
A: That’s normal! BEP20 uses Ethereum-style addresses starting with 0x. This indicates you’re on the Binance Smart Chain network.
Q: Should I always use BEP20 now?
A: For most users—especially those engaging with DApps, staking, or DeFi—yes. Use BEP2 only if required by a service like Binance DEX.
Final Tips for Safe Transfers
- Always double-check the network type before withdrawing.
- Start with a small test transaction when using a new wallet or service.
- Never share your private key or recovery phrase.
- Bookmark trusted tools like the Binance Chain Explorer and BscScan to track transactions.
As the Binance Smart Chain continues to grow—with thousands of DApps, staking pools, and NFT projects built on it—understanding how to properly manage your BNB across networks is more important than ever.
Whether you're diving into yield farming, launching a token, or simply storing assets securely, choosing the right chain ensures smooth, safe interactions in the Web3 space.
