STRUCTURED FOR SECURITY
Our Phased Engagement Process
We de-risk smart contract upgrades through a systematic, audit-backed approach. Each phase delivers clear deliverables and expert validation before proceeding.
01
Phase 1: Pre-Upgrade Security Audit
Comprehensive analysis of your existing contract system and the proposed upgrade logic. We identify architectural risks, state variable conflicts, and potential attack vectors before a single line of new code is written.
Deliverable: Detailed audit report with risk assessment and remediation roadmap.
