With the growing adoption of blockchain technology, managing digital assets across different wallets and exchanges has become a fundamental skill for crypto users. One common yet critical task is withdrawing Binance Coin (BNB), which supports multiple blockchain networks. Choosing the wrong network can result in irreversible loss of funds—so understanding the differences between chains is essential. This guide walks you through the process of safely withdrawing BNB from an exchange to a hot wallet like imToken, while highlighting key precautions and best practices.
Understanding BNB and Its Supported Chains
BNB exists in several forms across different blockchains, but two are most commonly used for deposits and withdrawals on exchanges:
- BEP2 BNB on the original Binance Chain
- BEP20 BNB on Binance Smart Chain (BSC)
While ERC20 BNB exists on Ethereum, most exchanges—including ProEX—do not support it for BNB transactions, so we’ll focus only on BEP2 and BEP20.
BEP2 BNB (Binance Chain)
- Address format: Starts with
bnb - Requires a Memo/Tag: Both the deposit address and a unique identifier (Memo) must be provided during withdrawal
- Risk: If the Memo is missing or incorrect, the funds may not be credited—or worse, lost permanently
BEP20 BNB (Binance Smart Chain)
- Address format: Starts with
0x - No Memo required: Only the receiving address is needed
- Lower fees: Generally offers faster and cheaper transactions compared to Ethereum

Step-by-Step: Checking Your imToken BNB Deposit Address
Before initiating any withdrawal, ensure you're using the correct chain and address in your wallet. Here’s how to find your BNB deposit address in imToken:
- Open the imToken app and log in
- Navigate to your wallet dashboard
- Select "BNB Smart Chain" as the primary network (if sending BEP20 BNB)
- Tap "Receive", then copy the displayed address
🔍 Important: Always double-check that the selected network matches the withdrawal chain on your exchange. Sending BEP20 tokens to a BEP2 address (or vice versa) will result in lost funds.
Withdrawing BNB from ProEX to imToken via BSC (BEP20)
This section outlines the step-by-step process for withdrawing BNB using the Binance Smart Chain:
Desktop Instructions
- Log in to your ProEX account
- Click on "Assets" at the top menu
- Select "Withdraw"
- Choose BNB as the currency
- From the network options, select "BSC" (this corresponds to BEP20)
- Paste your imToken 0x-address into the recipient field
- Enter the withdrawal amount
- Review the displayed transaction fee
- Confirm all details carefully
Once confirmed, complete the security verification (e.g., 2FA or email confirmation). The withdrawal request will be submitted for processing.
In many cases, withdrawals are processed within minutes—some users report receiving funds in under five minutes.
Withdrawing BNB to Another Exchange via BEP2 Chain
If you're transferring BNB to another exchange that uses the original Binance Chain (BEP2), follow these steps:
- In ProEX, go to Assets > Withdraw
- Select "BNB" as the coin
- Choose the "BNB" network (not BSC)
- Copy both the deposit address and Memo/Tag from the receiving exchange
- Paste them accurately into ProEX’s withdrawal form
- Enter the amount and confirm transaction details
⚠️ Critical Reminder: Most exchanges enforce Memo checks. ProEX prevents submission if the Memo is missing, helping protect users from errors.
Always verify:
- The destination supports BEP2 deposits
- Both address and Memo are correct
- You’re not sending to an incompatible chain
Common Mistakes & How to Avoid Them
Even experienced users can make costly mistakes when handling multi-chain assets. Here are frequent pitfalls:
- ❌ Sending BEP20 BNB to a BEP2-only address
- ❌ Forgetting to include the Memo on BEP2 transfers
- ❌ Copying an outdated or wrong wallet address
- ❌ Selecting Ethereum (ERC20) instead of BSC for BNB
👉 Avoid common transfer errors with real-time network validation tools.
To stay safe:
- Always test with a small amount first
- Double-check network names and address formats
- Use trusted wallets that clearly label chain types
Frequently Asked Questions (FAQ)
Q: What happens if I send BNB on the wrong chain?
A: Transactions sent via an incorrect network may not arrive at the destination wallet. In some cases, recovery is possible through the receiving platform’s support team—but this isn’t guaranteed. Prevention is key.
Q: Do I need a Memo for BEP20 BNB transfers?
A: No. Only BEP2 (Binance Chain) requires a Memo. BEP20 transactions use standard Ethereum-style addresses (0x...) and do not require additional tags.
Q: How do I know whether my wallet supports BEP2 or BEP20?
A: Check the address format: bnb... addresses are for BEP2; 0x... addresses are for BEP20. Wallets like imToken allow you to switch between networks manually.
Q: Why does ProEX show both “BNB” and “BSC” as options?
A: “BNB” refers to the BEP2 network (legacy Binance Chain), while “BSC” refers to BEP20 (Binance Smart Chain). They serve different purposes and are not interchangeable.
Q: Is one chain safer than the other?
A: Both are secure when used correctly. However, BEP20 is more widely adopted due to smart contract capabilities and lower fees, making it ideal for most users today.
Q: Can I convert BEP2 BNB to BEP20 BNB?
A: Yes—via a bridge or exchange that supports both formats. Many platforms automatically handle conversion upon deposit, but always confirm before initiating transfers.
Why Choosing the Right Chain Matters
As decentralized applications (dApps), DeFi protocols, and NFT platforms increasingly build on Binance Smart Chain, knowing how to correctly withdraw and manage BEP20 tokens has become a core competency in the crypto space. The low transaction fees and fast settlement times of BSC make it a preferred choice for active traders and investors alike.
Whether you're moving funds for trading, staking, or participating in token launches, ensuring compatibility between source, destination, and network type is non-negotiable.

Final Tips for Safe Crypto Transfers
- Always confirm network compatibility before initiating any withdrawal
- Use clipboard verification tools to avoid fake addresses from malware
- Keep your recovery phrase offline and never share it
- Enable two-factor authentication (2FA) on all exchange accounts
- Regularly update your wallet software
By mastering the nuances of multi-chain assets like BNB, you reduce risk and gain greater control over your digital wealth. Whether you're a beginner or seasoned user, attention to detail ensures smooth and secure transactions every time.
