## What it is
Manticore is a symbolic execution tool for analyzing Ethereum smart contracts, Linux ELF binaries, and WASM modules. It explores program states with symbolic inputs, generates concrete test inputs, and exposes a scriptable Python API for custom analyses.

## Use cases
- find crashes and vulnerabilities in binaries via symbolic execution
- analyze ethereum smart contracts for exploitable states
- generate inputs that reach a specific code path
- script custom dynamic binary analysis in python
- explore all reachable states of a program with symbolic inputs

## When to avoid
- you need an actively maintained tool - the project is archived
- you need symbolic execution for platforms other than EVM, ELF x86/ARM, or WASM
- you want a GUI-based reverse engineering tool
