Electrum review: is Bitcoin's oldest wallet still worth using?

Electrum shipped two years after Bitcoin itself and is still receiving updates in 2026, with version 4.8.2 as the current release. We installed it fresh, moved a small amount of Bitcoin through it, and paired it with a hardware wallet plugin to see whether fifteen years of continuous development has kept it relevant or just kept it alive.

The SPV model that made Electrum fast

Electrum's core trick has not changed since 2011: instead of downloading the entire Bitcoin blockchain like a full node, it uses Simplified Payment Verification, connecting to a network of Electrum servers that index the chain and prove your transactions are real without you storing hundreds of gigabytes yourself. This is why setup took us under two minutes and the wallet was usable within seconds of opening it, a real advantage over running your own full node just to check a balance.

The tradeoff, one Electrum states plainly rather than hides, is trust in whichever server you connect to for that verification. The default servers are decentralized and redundant, and your private keys never leave your machine regardless of which server you use, so the worst a malicious server can do is lie about balances, not steal funds.

Hardware wallets and multisig, through plugins

We tested Electrum's third-party plugin system by connecting a hardware signing device, and the pairing worked without needing a separate app open at the same time, everything ran inside Electrum itself. Multisignature wallets are supported natively too, useful for anyone splitting signing authority across multiple devices or people rather than trusting one seed phrase alone.

Where this falls short of the newer competition: independent comparisons count roughly twice as many supported hardware wallet models on Sparrow, particularly air-gapped devices that sign via QR code instead of a USB cable. If your security setup depends on one of those specific air-gapped models, check Electrum's plugin list before assuming support.

Downloading it safely matters more than usual here

Electrum's own site carries a blunt warning: do not download it from anywhere but electrum.org, and verify the GPG signature before running it. That warning exists because fake Electrum installers have circulated for years, a real risk for any wallet old and popular enough to be worth impersonating. We downloaded the AppImage build for Linux and confirmed the signature against the developer keys listed on the download page before running it, a step that takes a few extra minutes and is worth doing every single time.
