This involves setting up two wallets-a watching wallet and an offline wallet on a separate machine. Electrum also supports “cold storage” mode. When you come to the “Keystore” screen, choose “Use public or private keys.” Paste the master public key you copied earlier into the box, and click “Next.” Electrum alerts you that this is a watching only wallet, which cannot send payments by itself. This is perfect for installing Electrum on a machine you don’t own, such as one in your college or workplace.īegin by clicking on the “Wallet” menu option, then “Information.” Follow the instructions in step 1 to install Electrum on a new machine. When run in this mode, Electrum displays your current balance and allows you to receive payments, but you can’t spend your coins. If you’re concerned about the safety of your Bitcoins, consider setting up a watching wallet.

It’s also possible to audit the source before installing - as long as you have the knowledge and the time that requires, of course. People concerned about security are going to prefer compiling the Electrum Bitcoin wallet from its source code, because doing that makes it possible to verify the integrity and authenticity of the code. Another option is compiling both the library and the wallet from their source codes. It could be retrieved from the network:cryptocurrencies repo, but then it would make more sense to also install Electrum from that same repo (option #1). That creates a problem for openSUSE users, which is installing this library before actually installing Electrum. However, it is worth noting that Electrum depends on the secp256k1 library, which can be easily installed from the official repositories of Linux distros such as Debian or Ubuntu, but is not available on the official openSUSE repositories. In fact, this is the recommendation of the Electrum’s creator: “do not download Electrum from another source than, and learn to verify GPG signatures”. I haven’t found any mention to those packages on the official Electrum website. Note that the Flatpak package, like the openSUSE package, was also contributed by the community. But I believe it’s just as safe to install Electrum using Flatpak. I haven’t inspected this source code because I don’t understand how Flatpak packaging is done. The source code of the Electrum Flatpak package can be found on GitHub.
