Z3 Python Packages

crosshair-tool

An analysis tool for Python that blurs the line between testing and type systems.

manticore

Symbolic execution tool

a2a-greenhelix-sdk

Agent-to-agent payments, escrow and formal verification services

oxiz

OxiZ is a high-performance Satisfiability Modulo Theories (SMT) solver written entirely in Rust. This project is part of an initiative to reimplement Z3 in Pure Rust. Pure Rust is a fundamental requirement - no C/C++ dependencies, no FFI bindings, just clean, safe Rust code.
