A PROVEN FRAMEWORK
Our Penetration Testing Methodology
Our structured, multi-phase approach is designed to uncover critical vulnerabilities in your smart wallet architecture, providing actionable remediation guidance to secure your assets and user funds.
01
Reconnaissance & Scoping
We begin with a deep-dive analysis of your wallet's architecture, including contract dependencies, entry points, and permission models. This ensures our testing is comprehensive and tailored to your specific threat surface.

Exploitation & Proof-of-Concept
For every critical/high-risk finding, we develop a working Proof-of-Concept (PoC) exploit in a forked environment. This demonstrates the real-world impact and severity of the vulnerability.
