It's 140k addresses according to echevaria on IRC. He's a bitcoin expert. They can also rent more if they need to. Many hacker forums out there where you can rent botnets.

That issue linked above is interesting because the people affected were using 3.3.2. The DoS exploit in the client prevents < 3.3 from connecting but versions 3.3.0-3.3.2 can still connect to legit servers so their users don't see any immediate reason to upgrade to newer legit versions and they remain vulnerable. The DoS attack on legit servers increases the chances of these users connecting to a scammer's server.

If you have the latest updates from the mothership aka microsoft and this is still happening perhaps you should create an issue about it on github so that developers can look into it?

There are two things going on here:

- The seed is your backup in case you forget your password or your computer crashes. If you stored your seed on the PC as well you wouldn't be able to restore from it because it would be lost too. That's why they tell you to write it down.

- The wallet file does include your seed but it is encrypted with the password you set. Storing the seed in plaintext (unencrypted) on the computer would allow any program that can read that file to steal from you.

The primary reason is the first one - it serves as a backup. If you are confident you can remember the wallet password you can always rely on soft copy backups of the wallet file instead. You can do that via file > save copy.


The security of your PC matters. Doesn't matter what software you use if you get a malware infection you will lose money. Even with hardware wallets you can be fooled into paying to the wrong address or fooled into thinking you received money you didn't.

Electrum supports both cold storage and multisig setups. Another alternative is a 2fa wallet which is a form of multisig wallet that is easier for newbies to get started with.

Alternatively if you have the old wallet file you can simply save that on to a usb drive via file > save and open it in the new pc via file > open.

4. isn't necessary. electrum can be used. it wouldn't be worth using if it couldn't.

Non of the servers seem to be working ATM. Seems like the network is dead.

AWS is premium web hosting. If you want to run electrumx what you need is a bargain basement dedi from ovh, online.net or hetzner. Most public servers run in hetzner's DCs.  If you want to run electrum personal server a 4GB ram VPS from ramnode, vultr or DO will suffice. Make sure to enable pruning in bitcoin core to save space.

However unless you need the special features of electrum there is little point in running a complicated setup like above. Much easier to just switch to bitcoin core.

This command on the console tab (view > show console if you can't see it) will only display the private keys of addresses with unspent coins:

It is careless because you're dealing with digital cash and if you're not careful your money will be stolen and you won't be able to get it back.

You can set a password via wallet > password. Be sure to write down the seed before you do this in case you forget your password. Seed can be referred to via wallet > seed.

I've already explained above that if you install malware nothing on your system will be safe. The only step you can take is to not install malware in the first place. Learn to verify the gpg sig so you don't install malware by accident.

Learn to switch servers.  Keep doing this until it syncs.

See here for things to try.

Once you install malware on a system you should consider that entire system compromised. Installing multiple copies of electrum won't do anything for you.

However if this is a general question regarding support for multiple wallets then that is definitely there. You can create new wallets and switch between them.

All this tells you is that you correctly downloaded the same file. It doesn't tell you whether this file is legit electrum or fake electrum. That's why we do gpg signature verification. When you do that you are checking that the maintainer has signed the file in addition to checking that you downloaded it correctly. If you trust the maintainer ThomasV then you can trust the download.


You can still gpg verify the download so I suggest doing that. That'll make your life a lot easier. Here's a guide. You learn how to do this once it serves you every time you need to update electrum going forward. Electrum gets updates a lot so you will need this knowledge.



The wallet file is encrypted with the password you set in electrum. So the attacker gets access to your coins as soon as enter the password. If you never do that he doesn't get access to your coins although there's still the possibility that he installed other malware on your PC. It's also possible that he may get your encrypted wallet secrets and attempt to brute force your password at his convenience. So if you never entered the password you should still move your coins to a new wallet.


You can't. If the wallet is malware it doesn't matter what you do you will lose your coins.


Reinstall the OS, download, gpg verify and install genuine electrum and then move your coins to new wallets with new autogenerated seeds. You can create a new wallet via file > new/restore, enter a unique filename and click next for the rest of the steps.


Learn to gpg verify the download and save yourself the headache and worry.

Note also that he's claiming to have downloaded it from electrum.org. This is why its hard to take users at their word when they claim to have gotten it from the official site. Even when we ask them to confirm the URL from their browser's history they sometimes take the easy way out and just regurgitate what they think is the URL rather than checking.

Don't bother exporting your private keys. IT won't help you.

This is what you should do. First make a backup of your wallet file via file > save copy. This is a precautionary step. Then install the latest electrum version. In most cases it'll pick up your wallet file and upgrade it and you'll be good to go. If it doesn't then tell us and maybe we can help you.

Once you have the latest version running you should create a new wallet and move your coins to it. That's because in the event you lose your phone you will also lose your bitcoins since you didn't write down the seed.

Public electrum servers are currently being heavily ddosed. Your best bet is to install electrum personal server and use that in conjunction with electrum.

Another option is to migrate from electrum to bitcoin core. You can dump your private keys via wallet > private keys > export and then import them into bitcoin core using the importprivkey command.

Either way you're going to have to run your own full node.

This isn't safe. You are trusting that site to not steal from you. Please don't encourage people to do this everytime they face a small problem with bech32 addresses. Much better to tell them to simply create a legacy wallet.

Straight away. If it doesn't do that keep switching. Servers are being heavily ddosed because the phishing vulnerability has created an incentive for scammers to control which server you connect to. It's turned into a war!
