\section{Trade Execution via the regulated ATS}
|
|
|
|
\label{sec:trade}
|
|
% ============================================================================
|
|
|
|
Secondary trading of digital securities occurs through the regulated platform
|
|
ATS (Alternative Trading System), a SEC-registered trading venue.
|
|
|
|
\subsection{Order Flow}
|
|
|
|
\begin{enumerate}[leftmargin=1.4em]
|
|
\item Investor submits order via ArcaLabs trading interface.
|
|
\item Request authenticated by Hanzo IAM, routed through Hanzo
|
|
Gateway to the ArcaLabs trade engine.
|
|
\item Trade engine validates: investor whitelist status, lockup
|
|
compliance, accreditation validity.
|
|
\item Approved order forwarded to the regulated ATS matching engine.
|
|
\item ATS matches buy and sell orders. Matched trades return to
|
|
ArcaLabs for settlement.
|
|
\item Settlement: atomic swap of security tokens and USDC on Lux
|
|
C-Chain via MPC-signed transaction.
|
|
\end{enumerate}
|
|
|
|
\subsection{Gateway Configuration}
|
|
|
|
Hanzo Gateway handles the routing between ArcaLabs services and the
|
|
regulated ATS:
|
|
|
|
\begin{itemize}[leftmargin=1.4em]
|
|
\item \textbf{Rate limiting}: Per-investor and per-org request limits
|
|
to prevent abuse.
|
|
\item \textbf{Authentication}: IAM token validation at the gateway
|
|
layer. Invalid tokens rejected before reaching backend services.
|
|
\item \textbf{TLS}: End-to-end encryption. Mutual TLS between
|
|
Gateway and ATS.
|
|
\item \textbf{Audit logging}: Every request logged with investor
|
|
identity, timestamp, and response code.
|
|
\end{itemize}
