Electrum Bitcoin Wallet

Latest release: Electrum-4.4.4

Our executables are reproducible, and are signed independently by several builders.
The current executables have been signed by ThomasV, SomberNight, Emzy.

How to verify GPG signatures

GPG signatures are a proof that distributed files have been signed by the owner of the signing key. For example, if this website was compromised and the original Electrum files had been replaced, signature verification would fail, because the attacker would not be able to create valid signatures. (Note that an attacker would be able to create valid hashes, this is why we do not publish hashes of our binaries here, it does not bring any security).

In order to be able to verify GPG signatures, you need to import the public key of the signer. Electrum binaries are signed with ThomasV's public key. On Linux, you can import that key using the following command: gpg --import ThomasV.asc. Here are tutorials for Windows and macOS. When you import a key, you should check its fingerprint using independent sources, such as here, or use the Web of Trust.

Notes for Windows users

Electrum binaries are often flagged by various anti-virus software. There is nothing we can do about it, so please stop reporting that to us. Anti-virus software uses heuristics in order to determine if a program is malware, and that often results in false positives. If you trust the developers of the project, you can verify the GPG signature of Electrum binaries, and safely ignore any anti-virus warnings. If you do not trust the developers of the project, you should build the binaries yourself, or run the software from source. Finally, if you are really concerned about malware, you should not use an operating system that relies on anti-virus software.

Old versions of Windows might need to install the KB2999226 Windows update.

About Electrum

Electrum was created by Thomas Voegtlin in November 2011.
Since then, various developers have contributed to its source code.

Website and release security

Developers do not have direct unilateral write access to this website. Changes must be signed by both ThomasV and SomberNight, automatically checked by a script before made publicly visible. Release distributables are reproducible, and need to be signed by at least the same two keys, before the script exposes them to the webserver.
