Title: Seed and imported addresses
Post by: Orangina on December 23, 2016, 09:31:27 AM
If I import an address to my electrum wallet , and assuming that I already wrote the seed down on a piece of paper. Will I be able to restore the wallet with the imported address included ? If I can't then what I can do to be able to do so ?

You can't even import an address to a standard wallet with seed.

Even if that's possible and I missed it, the seed contains fixed number of addresses. So restoring won't restore your imported addresses.

You stand correct , I was searching on electrum documentations and It looks like It's impossible and I should sweep private keys instead. Can I create multiple wallets and while starting electrum , I can choose between them which one I want to run ?

Yes you can. Just go to File > New/Restore to create new wallet or File > Open to open other wallet files.

slightly OT, but can electrum sweep a key 'offline' - i mean can the sweep be initiated on an offline wallet and then loaded onto an online machine ?

cos i'm wondering if the sweep function is vulnerable to some form of attack if done on an online machine, as you're sweeping a private key...

Electrum will need to connect to the servers to get all the transactions data of the address you're trying to sweep so no, you can't do it offline.

It should be safe unless you have a malware in your PC.

It can't be done on an offline computer. But it can be done in a watch-only wallet on an online computer. So the private key of the target address can be on an offline PC. The private key you are sweeping would still be exposed though.
