Electrum (software)
bitcoin wallet
Electrum is a free non-custodial cryptocurrency wallet for Bitcoin and Lightning Network. It is available for Windows, Linux (pre-installed on Tails OS), macOS and Android. Electrum is written in Python and uses the Qt widget toolkit for the user interface. Electrum is a lightweight client: it does not download the entire blockchain and instead uses simplified payment verification. Transactions are sent to public servers. It was released in 2011.
Reception
Mayank Sharma of TechRadar praised the wallet's advanced features, such as multisignature transactions, while noting that the wallet is not designed for inexperienced users. Marco Monroy Robles of Money liked Electrum's simple setup process, but criticized its lack of direct customer support.
Security
Although wallet files are encrypted with PBKDF2, private keys are encrypted with AES256 with the user's password. This could allow an attacker with access to the encrypted data to decrypt the private keys using a dictionary attack or a brute force attack.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Electrum (software)”, the useful work is to connect “bitcoin wallet” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 29, 2026. The linked authority identifier is Q37307759. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2011.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
