Electrum is a lightweight, easy to use, open source Bitcoin client. It protects users from losing coins in a backup mistake or computer failure, because the wallet can be recovered by entering a secret phrase.
There is no waiting time when you start the client, because it does not download the Bitcoin blockchain.
Electrum’s focus is speed, with low resource usage and simplifying Bitcoin. Startup times are instant because it operates in conjunction with high-performance servers that handle the most complicated parts of the Bitcoin system.
- Several user interfaces, that share the same wallet code: Classic (Qt), Lite, Gtk, Android, Text (using curses).
- Uses a 128-bits random seed to generate your private keys.
- Instant on: Your client does not download the blockchain, it uses a remote server.
- Forgiving: Your wallet can be recovered from a secret seed.
- Safe: Private keys are never sent to the server. Information sent by the server is verified using SPV.
- Uses AES-256-CBC to encrypt the seed and private keys in the wallet.
- No downtimes: Several public servers are available, you can switch instantly.
- Ubiquitous: You can use the same wallet on different computers, it will auto-synchronize.
