Electrum – Bitcoin client

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.

Features include:

  • 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.
  • Cold Storage: You can have secure offline wallets and still safely spend from an online computer.
  • Open: You can export your private keys into other Bitcoin clients.
  • Supports sending to multisig addresses or P2SH addresses.
  • Lets you create and sign raw transactions right from the user interface using a form.
  • Offline wallets now work in a way similar to Armory.
  • SSL certificate validation.
  • Extensible with plugins.
  • Coinbase Buyback plugin.
