ZECmate Swing Wallet

Your best mate for Zcash

ZECmate Swing Wallet is a GUI destkop wallet for Zcash. This fully compatible sapling release is availalbe for macOS, Windows and Linux. Download the latest release from GitHub releases or head on to ZECmate Swing Wallet website .

This wallet is targeted at advanced users who understand the implications of running a full Zcash node on the local machine, maintaining a full local copy of the blockchain, maintaining and backing up the Zcash nodes' wallet.dat file etc! The wallet is not suitable for novice crypto-currency users!

SECURITY WARNING: Encryption of the wallet.dat file is an experimental feature. The wallet.dat needs to be backed up regularly (not just once - e.g. after every 30-40 outgoing transactions) and it must also be backed up after creating a new Z address.

AUTO-DEPRECATION WARNING: Wallet binary releases for Mac/Windows contain Zcash full node binaries. These have an auto-deprecation feature: they are considered outdated after 18 weeks and stop working. So they need to be updated to a newer version before this term expires. Users need to ensure they use an up-to-date version of the wallet (e.g. update the wallet every two months or so).

Building, installing and running the ZECmate Swing Wallet

Before installing the ZECmate Swing Wallet you need to have Zcash up and running. The following guide explains how to set up Zcash.

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).

1. Operating system and tools

   This program supports Linux, macOS and Windows. The Linux tools you need to build and run the Wallet GUI are Git, Java (JDK8) 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 ZECmate-swing-wallet Git repository:

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

   Change the current directory:

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

   Issue the build command:

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

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

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

   At this point the build process is finished the built GUI wallet program is the JAR file ./build/jars/ZECmate.jar. In addition the JAR file bitcoinj-core-0.14.5.jar is also necessary to run the wallet.

3. Installing the built ZECmate Swing 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 v2.0.3) which contains the command line tools zcash-cli and zcashd you need to take the created JAR files and copy them to directory /home/user/zcash/src (the same dir. that contains zcash-cli and zcashd). Example copy command:

   user@ubuntu:~/build-dir/ZECmate-swing-wallet$ cp -R -v ./build/jars/* /home/user/zcash/src    
   

4. Running the installed ZECmate Swing Wallet

   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 ZECmate.jar in directory /home/user/zcash/src one way to run it from command line is:

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

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

   Important: the Zcash configuration file ~/.zcash/zcash.conf needs to be correctly set up for the GUI wallet to work. Specifically the RPC user and password need to be set in it like:

   rpcuser=username
   rpcpassword=wjQOHVDQFLwztWp1Ehs09q7gdjHAXjd4E
    
   

Creating packages with Eclipse for Windows and macOS

Inno Setup is required for windows. Create build folder and copy the content of EclipseExample into it and rename windowsExample.xml to build.xml Create a dist folder in this build folder and copy the whole folder resources from src folder into it. Additionally in this build folder create a dist folder and copy your zcashd.exe, zcash-cli.exe into it if on windows. If on macOS copy your zcashd and zcash-cli and check their permisson is 755. on macOS a change in build.xml are needed from .exe to .dmg.

Known issues and limitations

1. Issue: ZECmate Swing Wallet is not compatible with applications that modify the Zcash wallet.dat file. The wallet should not be used with such applications on the same PC. For instance some distributed exchange applications are known to create watch-only addresses in the wallet.dat file that cause the GUI wallet to display a wrong balance and/or display addresses that do not belong to the wallet.
2. Limitation: if two users exchange text messages via the messaging UI TAB and one of them has a system clock, substantially running slow or fast by more than 1 minute, it is possible that this user will see text messages appearing out of order.
3. Limitation: if a messaging identity has been created (happens on first click on the messaging UI tab), then replacing the wallet.dat or changing the node configuration between mainnet and testnet will make the identity invalid. This will result in a wallet update error. To remove the error the directory ~/.ZECmate/messaging may be manually renamed or deleted (when the wallet is stopped). CAUTION: all messaging history will be lost in this case!
4. Limitation: The list of transactions may 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.
6. Limitation: When using a natively compiled wallet version (e.g. ZECmate.exe for Windows) on a very high resolution monitor with a specifically configured DPI scaling (enlargement) factor to make GUI elements look larger, the GUI elements of the wallet actually do not scale as expected. To correct this on Windows you need to right-click on ZECmate.exe and choose option:

Properties >> Compatibility >> Override High DPI scaling behavior >> Scaling Performed by (Application)
