Intro

Independent security reviews for software teams

HashThat LLC is a software security consultancy. We provide code audits, security reviews and secure development support to engineering teams, with a focus on smart contracts and blockchain-based systems.

We also help teams harden the desktop and mobile environments they work in. Whatever the engagement, the approach is the same: understand the system, find the risks that matter, and deliver clear, practical recommendations to address them.
