Is there a way to view my wallet private keys?
If you don't show them, then no, no one sees your keys. Beware of resources that ask you to enter your private key. Or they should be in the list of trusted ones from the developer. Use BGL Core.
I'm using BGL Core, I was asking if there is a way I can view my passphrase to write it down again, in case I lost my backup. Thank you.
