If there is a backup, you can contact customer service and say that you accidentally exported urgently, and there are stakes inside, requesting recovery, it can be done.

Can I ask everyone, when urgently exporting a wallet from Binance, how can I restore the assets to Binance with this kind of private key address? It seems that Binance only supports importing wallets using mnemonic phrases. Do I need to first import these into a third-party wallet and then use the mnemonic phrase to import to Binance? Is there a suitable platform for this?
