How to Use, Store and Sign Up with Electrum Bitcoin Wallet

Electrum is a popular bitcoin wallet available for desktop and Android users. It’s also one of bitcoin’s oldest wallets. Find out everything you need to know about Electrum today in our guide and review.

What is Electrum?

Electrum is an easy-to-use bitcoin wallet first released in November 2011, making it one of the first bitcoin wallets in the community. Over the years, Electrum has maintained a reputation for transparency and trustworthiness. It continues to be one of the most popular desktop bitcoin wallets in the world for all types of users.

The wallet is available as a free download via Electrum.org. You can install it on an offline computer for a cold storage setup. Or, you can keep your funds on an ordinary online computer and use your Electrum wallet for daily spending. Electrum gets along well with all major hardware wallets, which means it can easily be integrated into any wallet setup you’re running. It is known for its safety functions, recovery forgiveness, instantly on, no lock-in or downtimes, verification proof checking and offline cold storage benefits.

Unlike certain other crypto wallets, Electrum doesn’t support multiple cryptocurrencies. It doesn’t even support multiple forks of bitcoin: it just supports bitcoin (BTC). However, users have modified Electrum’s software over the years to create versions like Electron Cash or Electrum LTC. Electron Cash is an entirely separate project from Electrum made by a separate set of developers, although it uses most of the same coding. Electron Cash is one of the most popular Bitcoin Cash (BCH) desktop wallets.

Although most people know Electrum as a desktop bitcoin wallet, the team has also released an Android app. The app is available via the Google Play Store or as an .apk as a free download.

One of the biggest complaints about Electrum is that it was recently affected by one of the most serious security breaches in crypto history. In November 2017, a security issue was disclosed to the Electrum team. The issue had been affecting Electrum’s software since March 2016 (version 2.6). The exploit allowed a malicious website to gain control of your Electrum wallet and steal all of your bitcoin (if your wallet wasn’t encrypted with a password). Even if your wallet did have a password, a hacker could still redirect encrypted bitcoin keys from the wallet to their address. News of the exploit rattled the bitcoin community. Making the issue even worse was that it wasn’t fixed until January 2018. It’s unknown how many Electrum users lost bitcoin because of the exploit – if any. However, any Electrum users who haven’t updated their software since version 2.6 (say, those with funds held in cold storage) are still vulnerable.

Then, in April 2019, Electrum faced another serious security issue. Electrum users lost millions of dollars during a DoS attack against the network. Over 140,000 machines attacked the network with a phishing attack that steered users towards a fake version of the software. Hackers also implemented their own Electrum servers that hosted compromised versions of Electrum. Anyone using Electrum versions older than 3.3 were affected by the attack.

With these serious exploits in the past, Electrum continues to move forward as one of the best and most secure desktop bitcoin wallets available today.

Open Source: Electrum has over 9,000 commits on GitHub. Part of the reason why Electrum is so trusted is because of its thriving open source community. Overall, it’s one of the most actively-developed software projects in the crypto space.

Major Security Exploit in Old Versions: In January 2018, Electrum’s developers disclosed a major vulnerability in the software. That vulnerability was first revealed (privately) to the developers in November 2017, although it had been present in the Electrum software since March 2016. It’s unknown how many bitcoin were stolen through this exploit, if any, although it remains one of the biggest potential disasters in bitcoin history. Old versions of Electrum – like ones running on cold storage machines that haven’t been connected to the internet or updated in years – are still vulnerable to this exploit.

Written in Python: Electrum’s code is short, written in Python, and easy for anyone to review. It’s all available open-source via GitHub.

After installing the wallet, Electrum keeps your private keys stored on your computer as encrypted files. The keys are not sent to any remote servers. You can use Electrum on an online computer. Or, you can install Electrum on an offline computer for a cold storage solution.

Electrum is a lightweight Bitcoin client, which means you don’t have to install the entire 200GB bitcoin blockchain to use the wallet.

Electrum is an open-source wallet. That’s why its code has been adapted into other wallets – like Electron Cash for Bitcoin Cash (BCH).

Electrum lets you create multiple types of wallets using the software. You can create a standard wallet, for example, a wallet with 2FA, or a multi-signature wallet. You can also import an existing wallet to Electrum. Since coins held in Electrum aren’t locked in, you can also transfer your coins between different wallet software.

Electrum operates in a client/server configuration where the wallet (the client) is programmed by default to connect to a network of peers to verify that transactions are valid.
