Electrum is one of the most popular desktop wallets for Bitcoin. It only supports Bitcoin. The wallet is open source and was initially released in 2011 giving it a long history in cryptocurrency. Users of the wallet are in control of their own private keys. Users seed and passphrase are encrypted on their hard drive. In the case that they need to recover their device, they can use the passphrase provided to them. The node type is simplified payment verification and users do not have to download a full copy of the blockchain.

The wallet has multi-signature functionality. One of the key benefits of the Electrum wallet is that users can store their funds in cold storage which is a higher level of security.

There is also support for third-party plug-ins where users can connect hardware devices among others to their wallet.

Overall, it is a wallet with strong security features and functionality but limited support for cryptocurrencies.
