To proof the source of your assets deposited, you need to submit a video to our Customer Service team to show the related transaction records.
1. Record yourself logging in to your Binance account. Go to [Wallet] - [Overview] - [Transaction History] to find the relevant deposit record.
2. Then, go to the corresponding external platform that you withdrew funds from, and find the relevant transaction record and the TxID.
Please make sure that the withdrawal information is consistent with that in your Binance account.
