ZCash® Desktop GUI Wallet

Graphical user interface wrapper for the ZCash® command line tools

This program provides a Graphical User Interface (GUI) for the ZCash client tools that acts as a wrapper and presents the information in a user-friendly manner.

Experimental: ZCash Desktop GUI Wallet for MAC OS X is available

Building, installing and running the Wallet GUI

Before installing the Desktop GUI Wallet you need to have ZCash up and running. The following guide explains how to set up ZCash. There is also a user-friendly instructional video on the same topic.

For security reasons it is recommended to always build the GUI wallet program from GitHub source. The details of how to build it are described below (easy to follow). Project snapshot tags named x.xx-SNAPSHOT have been signed with the following public key. Users who are less experienced with working on a command line, may instead use this quite-user-friendly installation guide and usage guide. The following video also explains how to set up the GUI wallet. Users who insist on downloading a binary release may instead use ZCash Desktop GUI Wallet - binary release v0.46-beta

1. Operating system and tools

   As of December 2016 (ZCash v1.0.3) this program is only intended to work on Linux and Mac OS X (same limitation as ZCash). Future versions will work on Windows.
   The Linux tools you need to build and run the Wallet GUI are Git, Java (JDK7 or later) and Ant. If using Ubuntu Linux, they may be installed via command:

   user@ubuntu:~/build-dir$ sudo apt-get install git default-jdk ant
   

   For RedHat/CentOS/Fedora-type Linux systems the command is (like):

   user@centos:~/build-dir$ sudo yum install java-1.8.0-openjdk git ant 
   

   The name of the JDK package (java-1.8.0-openjdk) may vary depending on the Linux system, so you need to check it, if name java-1.8.0-openjdk is not accepted. If you have some other Linux distribution, please check your relevant documentation on installing Git, JDK and Ant. The commands git, java, javac and ant need to be startable from command line before proceeding with build.

2. Building from source code

   As a start you need to clone the zcash-swing-wallet-ui Git repository:

   user@ubuntu:~/build-dir$ git clone https://github.com/vaklinov/zcash-swing-wallet-ui.git
   

   Change the current directory:

   user@ubuntu:~/build-dir$ cd zcash-swing-wallet-ui/
   

   Issue the build command:

   user@ubuntu:~/build-dir/zcash-swing-wallet-ui$ ant -buildfile ./src/build/build.xml
   

   This takes a few seconds and when it finishes, it builds a JAR file ./build/jars/ZCashSwingWalletUI.jar. You need to make this file executable:

   user@ubuntu:~/build-dir/zcash-swing-wallet-ui$ chmod u+x ./build/jars/ZCashSwingWalletUI.jar
   

   At this point the build process is finished the built GUI wallet program is the JAR file ./build/jars/ZCashSwingWalletUI.jar

3. Installing the built ZCash GUI wallet

3.1. If you have built ZCash from source code:

Assuming you have already built from source code ZCash in directory /home/user/zcash/src (for example - this is the typical build dir. for ZCash v1.0.3) which contains the command line tools zcash-cli and zcashd you need to take the created file ./build/jars/ZCashSwingWalletUI.jar and copy it to diretcory /home/user/zcash/src (the same dir. that contains zcash-cli and zcashd). Example copy command:

user@ubuntu:~/build-dir/zcash-swing-wallet-ui$ cp ./build/jars/ZCashSwingWalletUI.jar /home/user/zcash/src    

3.2. If you have installed the ZCash binary packages

The command line tools zcash-cli and zcashd are placed by the package installer in:

/usr/bin/zcash-cli
/usr/bin/zcashd

The ZCash GUI wallet knows how to find them there. You may place the file ./build/jars/ZCashSwingWalletUI.jar anywhere in your /home directory that you find convenient and start it from there.

4. Running the installed ZCash GUI wallet

   Before running the GUI you need to start zcashd (e.g. zcashd --daemon). The wallet GUI is a Java program packaged as an executable JAR file. It may be run from command line or started from another GUI tool (e.g. file manager). Assuming you have already installed ZCash and the GUI Wallet ZCashSwingWalletUI.jar in directory /home/user/zcash/src one way to run it from command line is:

   user@ubuntu:~/build-dir/zcash-swing-wallet-ui$ java -jar /home/user/zcash/src/ZCashSwingWalletUI.jar
   

   If you are using Ubuntu (or similar ;) Linux you may instead just use the file manager and right-click on the ZCashSwingWalletUI.jar file and choose the option "Open with OpenJDK 8 Runtime". This will start the ZCash GUI wallet.

Known issues and limitations

1. Limitation: Wallet encryption has been temporarily disabled in ZCash due to stability problems. A corresponding issue #1552 has been opened by the ZCash developers. Correspondingly wallet encryption has been temporarily disabled in the ZCash Desktop GUI Wallet.
2. Issue: the GUI wallet does not work correctly if zcashd is started with a custom data directory, like: zcashd -datadir=/home/data/whatever This will be fixed in later versions.
3. Issue: GUI data tables (transactions/addresses etc.) allow copying of data via double click but also allow editing. The latter needs to be disabled.
4. Limitation: The list of transactions does not show all outgoing ones (specifically outgoing Z address transactions). A corresponding issue #1438 has been opened for the ZCash developers.
5. Limitation: The CPU percentage shown to be taken by zcashd on Linux is the average for the entire lifetime of the process. This is not very useful. This will be improved in future versions.
