What software can I use to calculate my private key from a seed (e.g. Trezor or Ledger)? I want to make sure I can use my seed from Trezor or Ledger (or others) in a backup process without using an actual Trezor or Ledger to do it.
I have to find out my private key. I probably also need to calculate the addresses I used for receiving bitcoin.
How can I do this?
Any wallet software that allows restoring from a BIP39 mnemonic will allow you to do that, such as Electrum.
However, you should not do this on your regular computer, since putting your private key on your computer defeats the purpose of having a hardware wallet. If you really have to verify your key is correct, and you'd like to maintain the security of having a hardware wallet, do it from a computer that isn't connected to the Internet.
