Speaking of how to build and dry a wallet FLOWER,
This is until May 2017 (ZCash v1.o.8.) This program is mainly tested for Linux and Mac OS X (limited to ZCash) for Windows, tests. It is possible to test the ability to use the tools needed to test this wallet, for example Linux tools can be installed via Git, Java (JDK7 or later) and if you are using Ant and Ubuntu Linux. For security reasons, it can be seen from the GitHub source that it is always recommended to install the GUL wallet app. When I get interested in this program, they note that it doesn’t work in 2018 either, and they note that it shouldn’t be used in the old-fashioned and productive either. So this wallet is considered obsolete because we have to note that this GUL wallet is having trouble updating its status. When we look at certain issues and limitations, it is possible to understand what this wallet is like. So in our brief note of these issues and limitations, we have to mention some of the following.
Problem: One solution is to modify the local settings to have a dot as a decimal point. And not everyone who appears in the transaction list is listed, especially the Z address operations that come out. I think it will improve in the future because it is not very useful.
