That is a domestic exchange site and also a wallet.
I contacted  them but they said it's out of control.😓
If there is another way please help me.
Thank you.

I sent my USDT asset from binance to a BTC exchange address belonges to my friend, now he has no seed wallet to retrieve my asset, please guide me if it's possible  to get it back.
I'm looking forward for your favor.
Best regards.
