Transferring BNB (Binance Coin) between exchanges and wallets is a common task in the crypto world, but it comes with a crucial caveat: you must select the correct blockchain network. A wrong choice could result in irreversible loss of funds. This guide walks you through the process of withdrawing BNB from an exchange like ProEX to a hot wallet such as imToken, highlighting key safety steps and network differences.
Whether you're a beginner or refining your crypto management skills, understanding BNB’s dual-chain support is essential. We'll cover everything from identifying your wallet's receiving address to confirming transaction details — all while emphasizing security and accuracy.

Understanding BNB Blockchain Options
BNB exists on multiple blockchains, but two are most commonly used for deposits and withdrawals:
- BEP2 (Binance Chain)
- BEP20 (Binance Smart Chain / BSC)
While some platforms also support ERC20 BNB (on Ethereum), most exchanges, including ProEX, only allow BEP2 and BEP20 for BNB transfers.
It's vital to match the withdrawal chain with your destination wallet’s supported network. Mismatched chains mean lost funds — and no recovery option.
BEP2 BNB (Binance Chain)
This version runs on the original Binance Chain, optimized for fast trading and low fees. When using BEP2:
- Address format: Starts with
bnb - Requires a Memo (or Tag): Both the address and a unique identifier (Memo) are mandatory
- Common use: Often used for transferring to other centralized exchanges
⚠️ Warning: If the address is incorrect, the Memo is missing, or the Memo is wrong, your funds will not be received — and cannot be recovered.
BEP20 BNB (Binance Smart Chain)
This runs on Binance Smart Chain (now called BNB Smart Chain), which supports smart contracts and decentralized applications (dApps). For BEP20:
- Address format: Starts with
0x - No Memo required: Only the wallet address is needed
- Common use: Ideal for sending to self-custody wallets like imToken, MetaMask, or Trust Wallet
Because most personal crypto wallets operate on BSC, BEP20 is typically the better choice for withdrawals to hot wallets.
How to Find Your imToken BNB Receiving Address
To receive BNB safely in imToken, follow these steps:
- Open the imToken app and log in.
- Switch your main network to BNB Smart Chain.
- Tap on the Receive button.
- Select BNB as the asset.
- Copy the displayed address (it will start with
0x).
📌 Make sure you're on the correct chain before copying. Sending BEP20 BNB to a BEP2 address — or vice versa — results in permanent loss.

Step-by-Step: Withdrawing BNB from ProEX to imToken
Here’s how to safely withdraw BNB from ProEX using the BSC (BEP20) network:
1. Log In and Navigate to Withdraw
- Sign in to your ProEX account.
- Click Assets > Withdraw.
2. Select Currency and Network
- Choose BNB as the coin.
- Select BSC as the network (this ensures BEP20 transfer).
- Paste your imToken BNB receiving address (starting with
0x).
3. Enter Amount and Confirm
- Input the amount of BNB to withdraw.
- Review the displayed network fee.
Double-check:
- Correct withdrawal address
- Correct chain (BSC/BEP20)
- Click Withdraw.
4. Confirm and Verify
- A confirmation popup will appear.
- Recheck all details carefully.
- Complete security verification (e.g., 2FA, email/SMS code).
- Submit the request.
ProEX typically processes withdrawals within minutes. In most cases, users report receiving funds in under five minutes.
✅ Pro Tip: ProEX prevents BEP2 withdrawals without a Memo, protecting users from accidental mistakes — a thoughtful feature for newcomers.
Key Differences: Withdrawing to Wallet vs. Exchange
| Destination | Recommended Chain | Requires Memo? | Address Format |
|---|---|---|---|
| Hot Wallet (e.g., imToken) | BEP20 (BSC) | No | 0x... |
| Centralized Exchange | BEP2 | Yes | bnb... |
Always confirm what chain your destination supports. When in doubt, start with a small test transaction.
Frequently Asked Questions (FAQs)
Q: What happens if I send BNB on the wrong chain?
A: If you send BEP2 BNB to a BEP20 address (or vice versa), the funds will likely be lost permanently. Most wallets and exchanges cannot recover them. Always verify the chain before confirming.
Q: Can I use the same address for both BEP2 and BEP20?
A: Some wallets generate compatible addresses, but the networks are separate. You must still select the correct withdrawal chain on the exchange side to ensure proper routing.
Q: Why does BEP2 require a Memo?
A: The Memo acts as a user identifier on Binance Chain. Since many users share similar deposit addresses, the Memo ensures funds go to the right person — especially important on centralized exchanges.
Q: Is BEP20 safer than BEP2?
A: Neither is inherently safer; both are secure when used correctly. However, BEP20 is more user-friendly for wallet-to-wallet transfers since it doesn’t require managing Memos.
Q: How do I know which chain my wallet supports?
A: Check your wallet’s network settings. In imToken or MetaMask, you can manually switch between networks like Ethereum, BSC, etc. If you see “BNB Smart Chain” or “BSC,” you’re set for BEP20.
Q: Are there fees for BNB withdrawals on BSC?
A: Yes, but they’re typically very low — often less than $1. Fees vary slightly based on network congestion but remain significantly cheaper than Ethereum’s gas fees.
Why Proper Chain Selection Matters in 2025
As blockchain ecosystems grow, multi-chain support becomes standard. However, this complexity increases risks for inexperienced users. Choosing the wrong chain during a withdrawal remains one of the top causes of lost crypto assets.
With Binance Smart Chain continuing to power thousands of dApps, DeFi platforms, and NFT marketplaces, knowing how to correctly transfer BEP20 BNB is now a fundamental skill for any crypto participant.

Final Tips for Safe Crypto Transfers
- Always double-check the network type before submitting any transaction.
- Use small test transfers when sending to a new wallet or exchange.
- Never share your private keys or recovery phrases.
- Enable two-factor authentication (2FA) on all exchange accounts.
- Bookmark official wallet addresses or save them securely.
By mastering BNB withdrawals across chains, you gain greater control over your digital assets — and reduce the risk of costly mistakes.
Remember: accuracy saves assets. Take an extra minute to verify — it could save you thousands.
