(I'm new to Electrum.)
I'm going to use Electrum (in Tails OS), configured to talk only to the Electrs on my own Raspiblitz, to transfer coin from a bunch of paper wallets to a proper deterministic wallet.
The paper wallets of course are all P2PKH, and I expect to have to type in private keys (tedious but I've done it before).
- Unless there's a way in Electrum to scan a WIF private key?
I can make an Electrum wallet to match my hardware wallet seed+passphrase.
- Unless I can't actually use a seed+passphrase with Electrum, only a seed?
Anyway, I'd like to have Bitcoin Core on the Raspiblitz fully sync'd, then turn off my cable modem (isolating my LAN from the network), then, in that configuration prepare and sign a bunch of transactions - one for each paper wallet. And
then either
- Delete the private keys from Electrum (how?), reconnect to the internet, and broadcast all transactions at once, or
- Export the signed transactions to some file (on a USB key), reboot (the private keys are definitely gone now), reconnect to the internet, import the transactions, and broadcast them, or
- ???
What I'd really like to avoid is doing the disconnect/enter private key/sign transaction/reboot/connect/transmit for
each paper wallet.
Hopefully you'll tell me the first option above just works: all the signed transactions just stack up with no place to go until the internet is available and then off they go. If not though, then what?
