Features

Encrypted wallet: the file that contains bitcoin private keys is protected with a password, and never leaves the user’s computer.
Deterministic key generation: If you lose your wallet file, you can recover it from its seed. You are protected from your own mistakes.
Instant on: by default the client does not download the blockchain, it requests that information from a server. No delays, always up-to-date.
Transactions are signed locally: Your private keys are not shared with the server. You do not have to trust the server with your money.
Cold storage: Keeping private keys offline is supported. Has a watch-only mode for online use.
Multisignature: Dividing the power to spend coins between multiple wallets is supported.
Hardware wallet integration: Many leading hardware wallets can interface with Electrum.
Redundancy: You are not tied to a particular server, and the server does not need to know you. One server going down doesn’t cause user downtimes.
No single point of failure: The server code is open source, anyone can run a server. Private keys can be exported and imported into other wallets.
Firewall friendly: The client does not need to open a port, it simply polls the server for updates.
Free software: Gnu GPL v3. Anyone can audit the code.
Written in Python. The code is short, and easy to review.
Add-ons: third-party plugins are supported.
Support for Bitcoin URIs, signed URIs and Bitcoin aliases

Electrum Personal Server

Electrum Personal Server has a different approach to a normal server. It is intended to be used by a single person only. Instead of creating a database of every transaction and address ever used on the bitcoin blockchain, Electrum Personal Server only tracks the user’s own wallets. This allows it to be much more efficient with resources, it does not need any extra data files and is compatible with Bitcoin Core‘s pruning feature.

Electrum Personal Server is the best way to combine Electrum’s feature-richness (hardware wallet integration, multisignature, mnemonic seed phrases, etc) with a full node‘s strong security and privacy.
