Answer 2: Source TX is a transaction that is used to move tokens from one blockchain to another. Specifically, when swapping BNB to ETH, a source TX is the transaction that moves BNB tokens from the Binance Chain to the Wormhole Network. This transaction is necessary for the swap to be successful. To ensure that the swap is successful, it is important to make sure that the source TX is confirmed and that all of the necessary information is provided. If you are having difficulty redeeming your tokens, you should check the status of your source TX to ensure that it has been confirmed. If the source TX has not been confirmed, you may need to resubmit it. If you are still having difficulty, you should contact Wormhole Network support for further assistance.
