 If you want to process binary data or use a client-side wallet instead of RPC, shared libraries must be built for your specific platform for this Java library to use.  This project uses a C++ counterpart library, [monero-cpp](https://github.com/monero-ecosystem/monero-cpp), to support JNI, which is included as a submodule in ./external/monero-cpp.
