Withdrawn BSC (BEP-20) tokens to Ethereum (ERC-20) network
If you’ve withdrawn BEP-20 tokens (like BNB and BUSD) using Ethereum (ERC-20) network, you should be able to retrieve them.
There are three different situations, each with its own solution:
1. You sent the tokens to a wallet that supports BSC and Ethereum.
If you have this type of wallet, you are lucky, you will just need enable correct network (ERC-20 in our case) of the coin (BNB or BUSD) and balance will appear in the wallet.
2. You sent the tokens to a wallet that only supports either BSC or Ethereum.
You will need to access your private key to import into a wallet that supports both.
3. You sent the tokens to crypto exchange.
Contact your exchange’s customer service. Provide them details like what funds you sent (eg. USDT, amount and TxID).
Withdrawn Tron (TRC-20) tokens to ERC-20 or BEP-20 network
If you’ve withdrawn TRC-20 token (like USDT-TRC20) using Ethereum (ERC-20) network, it is not possible to retrieve them. Unfortunately, it's mix of 2 different networks with different paramaters. They are lost.
