## Unreachable Code Detection

Unreachable code detection is the identification of parts of a program that can never be executed under any conditions. This code often represents dead logic, legacy functions, or mistakes in the implementation of conditional statements.

In smart contracts, unreachable code can lead to confusion during audits and may hide vulnerabilities by cluttering the codebase. Identifying and removing this code is a key part of the optimization and security hardening process.

It ensures that the contract is as lean and clear as possible, reducing the attack surface and gas costs. Static analysis tools are highly effective at mapping the control flow to find these dormant code segments, making them a standard part of the development toolkit.
