\section{Lux Secondary VMs Security Audit
Report}\label{lux-secondary-vms-security-audit-report}

\textbf{Date:} 2025-12-30 \textbf{Auditor:} CTO (Automated)
\textbf{Scope:} BridgeVM, GraphVM, KeyVM, QuantumVM, ExchangeVM,
ThresholdVM, ZKVM, AIVM, DexVM

\begin{center}\rule{0.5\linewidth}{0.5pt}\end{center}

\subsection{Executive Summary}\label{executive-summary}

This audit covers nine specialized Virtual Machines in the Lux ecosystem
beyond the core PlatformVM/C-Chain. These VMs provide unique
functionality for cross-chain bridging, graph queries, key management,
post-quantum cryptography, UTXO exchange, threshold MPC, zero-knowledge
proofs, AI compute, and decentralized exchange operations.

\textbf{Overall Assessment:} Mixed maturity levels. Several VMs have
strong foundational implementations while others remain in early
development with significant gaps.

\subsubsection{2. Warp Integration}\label{2-warp-integration}

Several VMs define warp.Error handling but don\textquotesingle t
validate messages. Need consistent cross-chain verification.

\subsubsection{3. Database Persistence}\label{3-database-persistence}

Multiple VMs have TODO markers for database persistence (KeyVM,
QuantumVM, AIVM). Critical for production.
