Monocerus is a lightweight, multi-platform, multi-architecture emulator framework for smart contracts of blockchain platforms, and beyond.

Monocerus offers some key features:

• Emulate smart contract's byte-code, that requires no source code.
• Muli-platform: native build for Windows & *nix (with Mac OSX, Linux, *BSD & Solaris confirmed).
• Clean/simple/lightweight/intuitive blockchain-neutral API.
• Implemented in pure C language, with (future) support for bindings of other languages.
• Allow fine-grained instrumentation, with user-customized callbacks.
• Thread-safe by design.
• Open source with permissive license
