The Nash Extension does not show your private key for safety reasons. After you create your account, you should have access to your encrypted key, private key backup and your wallet file (JSON). Write down your encrypted key and backup code and store them in a safe place. These keys can be used to recover your account.

You can export your wallet file by;

1. Log in to your Nash Extension wallet.
   
   
   
2. Click on the three lines in the top-right corner of the extension window.
3. Select "Accounts".
   
   
   
4. Click on "Download Wallet File (JSON)".
