C++ Canister Development Kit
icpp-pro is a CDK to develop C++ smart contracts for the Internet Computer.
"...needed to have more flexibility with using c++ code as backend server. With the introduction of icpp within icp, it is now possible to create something that crosses the borders of what is possible."Ktimam Imam (ICSoccerWorld)
