Windows installation

If you wish to compile the library on Windows yourself, download the latest sources from the GitHub page by clicking the 'Download' button on the upper right corner. Additionally, you need to install the following libraries:

OpenSSL 3.0.8 or higher

• Follow the tutorial to install OpenSSL on windows. Here is a small summary of the steps:
• Open the x64 Native tools command prompt
• Run: perl Configure VC-WIN64A --prefix=C:\local\openssl3.0.8 (you may replace the prefix with the installation path of your choice).
• Run: nmake
• Run: nmake install
• The OpenSSL headers and libraries will be installed in the installation path you provided.

Sodium

• Download here the latest pre-builts for GNU compiler.
• Uncompress the .tar.gz into your location of choice. The resulting folder will contain the static library and the headers.

Google tests (optional)

• To run the Google tests, download the latest release here.
• Uncompress the .zip and open a terminal.
• Type cd googletest
• Type mkdir build
• Type cd build
• Type cmake ..
• Type cmake --build .
• This will create the libgtest.a library. Make sure to know where you store them, along with the include directory.

Linux installation

• If you wish to compile the library on Linux yourself, download the latest sources from the GitHub page by clicking the Download button on the upper right corner. Additionally, you will need the latest version of OpenSSL 3 and libsodium.
• You will need to install OpenSSL 3 and libsodium. If your Linux distro supports the Advanced Packaging Tool (APT), run the install.sh script. If not, you will need to manually install the packages corresponding to the OpenSSL static libraries, the OpenSSL include files, the libsodium static libraries and the libsodium include files. In most distros, the libraries go by the names of openssl and libsodium, and the include files go by the names of openssl-dev and libsodium-dev.
• To install the libsodium library, go to this page, and download the latest stable release. Then, run the commands ./configure, make && make check and sudo make install
• If you wish to run the Google tests suite, install googletests on your system. You can run the installgtest.sh file and it will install it for you (if your distro uses APT, if not, you'll need to do it manually). You can also install it manually by typing sudo apt-get install libgtest-dev, then cd /usr/src/gtest and sudo cmake CMakeLists.txt followed by sudo make.

MacOS installation

• If you wish to compile the library on MacOS yourself, download the latest sources from the GitHub page by clicking the Download button on the upper right corner. Additionally, you will need the latest version of OpenSSL 3 and libsodium.
• You will need to install OpenSSL 3 and libsodium. Install brew, and run the install_macos.sh script. This will install libsodium and openssl.
• If you wish to run the Google tests suite, install googletests on your system: brew install googletest.

Compilation

Library

A compilation script is provided for windows (windows-compile.bat), linux (linux-compile.sh) and MacOS (macos-compile.sh). Please, modify it and set the value of the following macros:

• MULTIFUNGIBLE_NETWORK: Select the network in which the library will run (Local, Testnet, Devnet, Mainnet). Example: -DMULTIFUNGIBLE_NETWORK=Mainnet (without " ").
• MULTIFUNGIBLE_CONFIG_FILE: Select the location of the config file that the library will use during execution. You can set it to ./config.toml if you are going to place it next to the executable that will load the Multifungible library. Example: -DMULTIFUNGIBLE_CONFIG_FILE="./config.toml".
• __SIMULATE__: Specifies if every interaction with the blockchain should be simulated first with MultiversX simulation tool. Example: -D__SIMULATE__=true. By default, it is set to false.

If you are compiling on windows with windows-compile.bat, please set the following macros as well:

• CMAKE_C_COMPILER: Select the location of the C compiler. Example: -DCMAKE_C_COMPILER="C:/TDM-GCC-64/bin/gcc.exe".
• CMAKE_CXX_COMPILER: Select the location of the C++ compiler. Example: -DCMAKE_CXX_COMPILER="C:/TDM-GCC-64/bin/g++.exe".
• LIBSODIUM_INCLUDE_PATH: Select the path to the sodium folder, which contains the headers of the libsodium library. Example: -DLIBSODIUM_INCLUDE_PATH="C:/libsodium/include".
• LIBSODIUM_LIB_PATH: Select the path to the compiled libsodium library (libsodium.a). Example: -DLIBSODIUM_LIB_PATH="C:/libsodium/lib".
• OPENSSL_INCLUDE_PATH: Select the path to the openssl folder, containing the headers of the openssl library. Example: -DOPENSSL_INCLUDE_PATH="C:/openssl3.0.8/include".
• OPENSSL_LIB_PATH: Select the path to the compiled openssl library (libcrypto.lib and libssl.lib). Example: -DOPENSSL_LIB_PATH="C:/openssl3.0.8/lib".

The script will compile either a DLL (if you're using windows) or a shared object (if you're using Linux) into the ./bin folder. This is the file that you need to have in your programs (along with config.toml) if you want to access Multifungible's functions.

Google tests

A compilation script is provided for windows (windows-compile-gtests.bat), linux (linux-compile-gtests.sh) and MacOS (macos-compile-gtests.sh). Please, modify it and set the value of the following macros:

• BUILD_TESTS: This macro turns the Google test compilation ON. It is set to OFF by default. To use it, -DBUILD_TESTS=ON.
• MULTIFUNGIBLE_NETWORK: Set the network to Local with the parameter -DMULTIFUNGIBLE_NETWORK=Local.
• MULTIFUNGIBLE_CONFIG_FILE: Set the location of the config file to ../config folder/config.toml.

If you are compiling on windows, please set the following macros as well:

• GOOGLETESTS_INCLUDE_PATH: Select the location of the Google test headers folder. Example: -DGOOGLETESTS_INCLUDE_PATH="C:/GoogleTests/include".
• GOOGLETESTS_LIB_PATH: Select the location of the Google test lib folder. Example: -DGOOGLETESTS_LIB_PATH="C:/GoogleTests/lib".

The script will compile an executable into the ./bin folder. This is the file that you need to execute in order to run the tests on the Testnet.

Run tests

In order to run the test suite, you will need to navigate to the ./bin folder and perform the following actions:

• Create a set of test wallets in the './test' folder. To create them, run the executable with the option -c, like this: .\Multifungible.exe -c. This will create a main wallet and display its address on the console. The program will block until you click ENTER after you complete the next step.
• Open a new console and launch the xNetwork local testnet with sudo xnetwork. When asked to configure the address that will receive 1.000.000 EGLD, enter the address shown on the Multifungible console. Once the local testnet is up and running, click ENTER on the Multifungible console. This will make a few transactions to load additional wallets with enough EGLD.
• To see the public addresses of your wallets, run .\Multifungible.exe -s.
• Run the program .\Multifungible.exe. This will run all the tests one by one
• It is possible that some tests fail. Keep in mind that these tests rely heavily on the local blockchain API, and sometimes, the information retrieved from the API is not up to date.

How to use?

Here are some important guidelines on how to use Multifungible:

• The main purpose of this library is to facilitate the management of collections and tokens on the MultiversX blockchain by the use of simple JSON wallets (one private-public key pair).
• If you're not familiar with all the features that are available in the MultiversX blockchain, it is recommended that you read this library's documentation as well as the definitions of the concepts used by its functions. You can find them here. You can also read Multivers X's official documentation on ESDT tokens and NFTs to acquire a complete understanding of their functionning.
• This piece of software is meant to be compiled as a dynamic library object and have its functions called from your application.
• Functions that need to broadcast information to the blockchain (like collection and token issuances, or token transfers) wait until the transactions have completed. This means that the function is blocking the program for at most the timeout specified at compilation.
• The library can be compiled with the Simulate option. This option makes a call to the simulation end point of the MultiversX proxy, which checks if the transaction will be successfully executed (before we actually broadcast it).
• Issuance of collections and tokens have a cost of 0.05 EGLD. This documentation specifies which functions have this cost, so that you can load the wallet with sufficient funds before calling them.
• All functions of this library that change the state of the blockchain need gas to pay the transaction fees. Make sure to load your wallet with at least 0.001 EGLD to ensure that even the biggest transactions are broadcasted.

Give a role on a collection to an address. The collection must have the property canAddSpecialRoles. The roles that can be given to an SFT collection are ESDTRoleNFTCreate, ESDTRoleNFTBurn, ESDTTransferRole and ESDTRoleNFTAddQuantity.
