Cryptocurrency trading involves exchanging, withdrawing, or sending digital assets across various networks. These transactions typically occur via crypto wallets, where assets are stored. Each crypto asset adheres to specific standards (e.g., BEP-20, ERC-20, TRC-20, BEP-2), which determine their compatible blockchains and wallets. Understanding these standards is crucial to avoid sending tokens to incorrect networks.
Binance, a centralized exchange, offers custodial wallets for asset storage. However, many users prefer non-custodial wallets for security, using Binance primarily for trading or liquidation. Mistakes during withdrawals or transfers—such as confusing BEP-20 with BEP-2 or ERC-20 with TRC-20—can lead to tokens sent to wrong networks. Here’s how to recover them.
Steps to Retrieve Crypto Sent to the Wrong Network
1. Tokens Sent to a Wallet Supporting Both Ethereum and BSC
- Solution: Transfer the tokens back to Binance on the correct network.
Example: Use MetaMask to manually import tokens:
- Click "Import Tokens" and search for the token.
- If unavailable, select "Custom Token" and enter the contract address, symbol, and decimal.
- Once added, send the tokens back to Binance via the appropriate network (e.g., BEP-20 for BSC).

2. Tokens Sent to a Wallet Supporting Only One Network
- Solution: Import the private key or mnemonic phrase into a wallet supporting both networks (e.g., MetaMask, Trust Wallet).
Process:
- Access the new wallet’s "Import Account" feature.
- Enter the private key or JSON file.
- Manually add the BSC network if needed (RPC URL:

3. Tokens Sent to an Exchange or Custodial Wallet
- Solution: Contact the exchange’s customer support for retrieval assistance.
Retrieving BEP-20 or ERC-20 Tokens Sent Incorrectly
If you send:
- ERC-20 tokens to BSC: Tokens become BEP-20 (check Bscscan for transaction status).
- BEP-20 tokens to Ethereum: Tokens become ERC-20 (check Etherscan).
Action: Send the tokens back to Binance using the current network (e.g., BEP-20 → Ethereum requires ERC-20 transfer to Binance).
Using Binance Bridge for Cross-Chain Transfers
Binance Bridge converts tokens between networks (e.g., Ethereum ↔ BSC). Follow these steps:
- Navigate to Binance Bridge.
- Select the input and output networks.
- Enter the amount and complete the transfer.

Converting BEP-20 ETH to ERC-20 ETH
- Withdraw ETH to Binance via BEP-20 network.
- Withdraw again from Binance using the ERC-20 network.
- Ensure sufficient BNB for BSC gas fees.
FAQ
Q1: Can I recover tokens sent to an unsupported network?
A1: Yes, by importing the private key into a compatible wallet or contacting the exchange.
Q2: How do I confirm a transaction’s network?
A2: Check Etherscan (ERC-20) or Bscscan (BEP-20).
Q3: What if my wallet doesn’t show the token?
A3: Manually add the token using its contract address.
Q4: Is Binance Bridge free?
A4: No, gas fees apply (paid in BNB for BSC).
Q5: Can I use a mnemonic phrase instead of a private key?
A5: Yes, if the wallet supports it (e.g., MetaMask).
Summary
Always verify the network before sending crypto. If mistakes occur, act quickly using the methods above. For complex cases, consult Binance support or use tools like MetaMask and Binance Bridge.
