Help needed. WlF private key

[Mastah]

Finally found my old btc wallet, not wallet at all, but a WlF private key from blockchain. But how to restore the wallet using WlF? I cannot find out.


Help would be appreciated!

Install Electrum, save your backup seed words, and sweep the private key.

Didn't find Seed phrase from blockchain (or you meant Electrum new seed phrase). Got only WlF. Is it possible to restore only with WlF?

Install Electrum, save your Electrum backup seed words, after you have saved your Electrum backup seed words and finished installing Electrum then use Electrum to sweep the private key into Electrum.  That is how you import a private key into Electrum so you can recover your Bitcoins.

He mean Electrum new seed phrase because you'll be creating a new wallet there and sweep your private key (WIF). Yes it's possible.

Yes, this is possible.

But if you further want to keep your bitcoins, you should do what LoyceV suggested and first create a new wallet. Then move your funds from your old address to your new wallet (sweeping).
If you don't want to further keep your coins, but just want to send them to an exchange or something like that, simply importing the private key will work. You don't need to create a new wallet/seed in this case.

When downloading/installing electrum, make sure you do verify the signature AND that your PC is clean. Also, if you are creating a wallet, make sure to backup your seed (only offline! - NOT on your computer).
