\section{Integration with Lux Ecosystem}


\subsection{M-Chain MPC Bridge}

Lux Credit leverages M-Chain's threshold custody infrastructure:

\begin{itemize}
\item \textbf{15-of-21 Validators}: Distributed key management
\item \textbf{Sub-200ms Signing}: Fast cross-chain operations
\item \textbf{Quantum-Safe}: Pulsar lattice-based signatures
\item \textbf{Economic Security}: \$15M validator stake
\end{itemize}

\subsection{Z-Chain Privacy Integration}

Optional privacy features via Z-Chain:

\begin{lstlisting}[language=Solidity, basicstyle=\small\ttfamily]
interface IPrivateLending {
    // Shield loan position for privacy
    function shieldLoan(
        bytes32 loanId,
        bytes calldata zkProof
    ) external;
    
    // Private collateral deposit
    function depositPrivateCollateral(
        bytes32 commitment,
        bytes calldata zkProof
    ) external returns (bytes32);
    
    // Confidential repayment
    function repayPrivate(
        bytes32 nullifier,
        bytes calldata zkProof
    ) external;
}
\end{lstlisting}

\subsection{X-Chain DEX Integration}

Automatic collateral rebalancing via Lightspeed DEX:

\begin{itemize}
\item Sub-261ms order execution
\item MEV-resistant fair ordering
\item Atomic collateral swaps
\item Optimal execution routing
\end{itemize}
