Withdrawing BNB (Binance Coin) requires careful attention to blockchain selection, as using the wrong network can result in permanent loss of funds. This guide explains the differences between BEP2 and BEP20 chains and provides step-by-step instructions for transferring BNB from ProEX to imToken wallet.
Understanding BNB Blockchain Networks
BNB operates on three distinct networks, but most exchanges support only two:
BEP2 (Binance Chain)
- Address format: Starts with
bnb - Requires both address + memo (like bank account details)
- Used for native Binance Chain transactions
- Address format: Starts with
BEP20 (Binance Smart Chain/BSC)
- Address format: Starts with
0x(Ethereum-compatible) - Only requires address
- Powers most DeFi applications
- Address format: Starts with
ERC20 (Ethereum Network)

Step-by-Step Withdrawal Process from ProEX to imToken
1. Prepare Your imToken Wallet
- Open imToken and select "BNB Smart Chain" as your active network
- Tap "Receive" and copy your BEP20 address (starts with 0x)
2. Initiate Withdrawal on ProEX (Desktop)
- Navigate to Assets → Withdraw
- Select BSC network for BEP20 transfers
- Paste your imToken address
- Enter amount and confirm transaction fees
For Exchange Deposits (BEP2):
- Choose BNB network instead
- Provide both address (starts with bnb) AND memo
- ProEX prevents submissions without memo to protect users
Critical Safety Tips
✅ Always double-check:
- Network selection (BSC vs. BNB)
- Address accuracy
- Memo requirement (for BEP2)
❌ Common mistakes:
- Sending BEP20 to BEP2 address (or vice versa)
- Omitting memo on BEP2 transfers
- Using wrong network for destination wallet
