Electrum will automatically keep making new addresses as you start using your wallet. So don't worry. Just go with the flow.

Delete the blockchain_headers and config file found here:

C:\Users\XXXX\AppData\Roaming\Electrum\

Start electrum. If it doesn's start then take a look at your default_wallet file using a text editor like notepad. Can you see human readable text? It should look something like this:


The above is just an example. Your addresses most likely start with 1. The point being that it should be readable text. Do you see something like this?

The seeds are generated from random numbers. Astronomically large random numbers derived from entropy collected by the operating system (not the time or anything predictable like that). There is no way to predict what number was used and no way to recreate it unless you saved the seed. The seed is the random number in a human friendly format.

However if you are asking why electrum would choose to create a new wallet then the answer is that it finds there is no wallet in the data directory and you haven't specified one in the command line via the -w switch to it begins the process of creating a wallet for you. The location of the data directory is given here. You can also create additional wallets using the file menu > new/restore option and open them using file > open.

Say you have a 2 of 3 wallet with 1 key on your PC, one backup key you store offline and one on another device. If you lose your other device and you wish to recover your wallet you can enter the seed on your PC + the backup seed you've stored offline.

open up your wallet file in a text editor like notepad. Do you see two xprvs like this:

http://paste.ubuntu.com/23745557/

backup the seed by writing it down on a piece of paper. then upgrade to the latest version of electrum. it may be that the bug you have encountered has already been fixed.

if the above doesn't work then I suggest restoring your wallet via the seed. Use file > new/restore to begin the process.

Yep but that only works if you have some idea what the password might be. So first try to recall what the password might have been. There have been many discussions on this forum about bruteforcing passwords. I suggest searching the electrum section here.

Regarding 3, you are not supposed to backup the entire data directory. Open your wallet in electrum and then use the file menu > save copy option to backup your wallet file. That's all you need.

You definitely set a password. Otherwise your seed would not be encrypted.

When setting a password you are supposed to enter it twice. How could you not remember doing that? Did you enter some sort of dummy password because you were in a hurry? Like 123 or something?

You didn't note down the seed and you entered a password that you can't remember. This is all very irresponsible.

I honestly don't know what you can do with that corrupt file. Have you considered using a professional data recovery service? I don't know what else to suggest.

look up the tx id on a block explorer like blockchain.info. if it's listed there then some mining pools are still carrying that in their memory and it might yet confirm.  you can get the tx id  by right clicking on the tx in the history tab and selecting details.

do you have a copy of the wallet file?

It's unlikely that Electrum ltc releases are signed by ThomasV. It is a fork designed to support litecoin.

@BlueTopaz: You can see links to community forums for electrum LTC on their homepage:

I suggest consulting people there if you need help. This forum here is for Electrum BTC.

Hi Jonald. Good to see you here after a long time. The PBKDF2 thing was introduced with version 2.0:

https://github.com/spesmilo/electrum/blob/9285a7198ee1f19571d10453db1b708fc6306e9a/lib/mnemonic.py#L127

This approach was originally proposed by the bip39 standard.

public keys and addresses are not the same thing.

write down the 12 word seed and you'll be able to recover your entire wallet at any time including all addresses past, present and future. there is no need to export private keys.

you download the binaries from electrum.org. the public keys you grab from github. both electrum.org and github would have to be compromised for the binaries to be fake.

furthermore you can check the web of trust i..e who trusts the gpg keys of animazing, thomasv and other developers. you can see that  gpg public key fingerprints are the same as the ones specified above in this thread. there are so many different places where these things are discussed. surely they can't all be fake?

i've told you above to open the wallet file using 1.8 and use one of the options in the menus to view the seed. is there an option like that in the menus? there is also a seed icon in the bottom part of the window that you can use. write down the seed and restore the wallet using the latest version of electrum.

that is not referring to the date. it is referring to the number of confirmations the transaction has got. electrum doesn't think it has had enough confirmations yet so it is showing that not verified status. you shouldn't worry about it. it'll automatically fix itself over time.

for all intents and purposes that transaction has confirmed. I would consider it a done deal.

no it's normal. you really should have learned how bitcoin works before using it. transactions take an average of 10 minutes for a single confirmation. i don't know what threshold of confirmations electrum deems fit but generally speaking 6 confirmations (60 minutes on average) is considered sufficient for a transaction to be deemed irreversible.

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.
