Etherwall is a secure open source ethereum wallet for Windows, Mac OS X and Linux operating systems. Etherwall supports the TREZOR ONE hardware wallet for storing keys. (NOTE: Trezor T is currently not supported).

  1. In full node client mode all data is stored on your computer, but you have to download the full (30GB+ and growing) ethereum blockchain.
  2. In thin client mode all your account data stays on your computer. A remote ethereum node is used to get latest blockchain information and send signed transaction.

Browser wallets introduce many vulnerabilities.  These include centralized servers, disgruntled employees, plug-ins, Java Script…..etc.  Each new path can introduce security holes, leaving your data, keys, I.D. and wallet exposed.
