The Emerald wallet client stands out as a wallet that is very easy to install on desktop devices, since it is very light and does not download its entire chain of blocks to these devices. It works from servers, thus offering a good service. Emerald allows you to have up to 6 currencies in your wallet, including altacoins. The storage of these tokens is really secure, the wallet can be recovered with the private key file, using other devices in a very simple way and configuring this client does not require so much protocol.
