\subsection{Deployment Model}
|
|
|
|
The ATS is implemented as a single Go binary (downstream-tenant ATS Go binary) running on Hanzo Base. Hanzo Base provides an embedded SQLite-compatible database with real-time subscriptions, authentication, and file storage. The binary packages all ATS functionality into a single deployable unit.

\begin{table}[H]

|
|
\caption{ATS system components.}
|
|
\label{tab:components}
|
|
\begin{tabular}{lrl}
|
|
\toprule
|
|
\textbf{Component} & \textbf{Count} & \textbf{Description} \\
|
|
\midrule
|
|
Collections & 32 & Data models (orders, securities, accounts, \ldots) \\
|
|
API routes & 64 & REST endpoints (/v1/\ldots) \\
|
|
Cron jobs & 19 & Scheduled tasks (settlement, compliance, \ldots) \\
|
|
Event hooks & 47 & Real-time triggers on collection changes \\
|
|
MPC signers & 3 & Threshold signature participants \\
|
|
\bottomrule
|
|
\end{tabular}
|
|
\end{table}
|
|
|
|
\subsection{Collection Schema}
|
|
|
|
The 32 collections partition the system state into distinct concerns:

\begin{table}[H]

\caption{Collection groups and their members.}
|
|
\label{tab:collections}

|
\begin{tabular}{lp{8cm}}
|
|
\toprule
|
|
\textbf{Group} & \textbf{Collections} \\
|
|
\midrule
|
|
Identity & accounts, investors, accreditations, kyc\_checks, aml\_screens \\
|
|
Securities & securities, offerings, partitions, documents, corporate\_actions \\
|
|
Trading & orders, executions, order\_books, quotes, rfqs \\
|
|
Settlement & settlements, transfers, mpc\_requests, mpc\_signatures \\
|
|
Compliance & compliance\_events, regulatory\_reports, audit\_logs, restrictions \\
|
|
Integration & alpaca\_accounts, alpaca\_orders, simplici\_checks, provider\_configs \\
|

System & configs, cron\_logs, webhooks, notifications \\
|
|
\bottomrule
|
|
\end{tabular}
|
|
\end{table}
|
|
|
|
\subsection{API Surface}
|
|
|
|
The 64 routes follow a consistent pattern under \texttt{/v1/}:
|
|
|
|
\begin{lstlisting}[language=Go,caption={Route registration pattern.}]
|
|
func RegisterRoutes(app *base.App) {
|
|
v1 := app.Group("/v1")
|
|
|
|
// Trading
|
|
v1.POST("/orders", createOrder)
|
|
v1.GET("/orders/:id", getOrder)
|
|
v1.DELETE("/orders/:id", cancelOrder)
|
|
v1.GET("/orderbook/:security", getOrderBook)
|
|
|
|
// Securities
|
|
v1.GET("/securities", listSecurities)
|
|
v1.GET("/securities/:id", getSecurityDetail)
|
|
v1.POST("/securities/:id/transfer", initiateTransfer)
|
|
|
|
// Settlement
|
|
v1.POST("/settlements/execute", executeSettlement)
|
|
v1.GET("/settlements/:id/status", getSettlementStatus)
|
|
|
|
// Compliance
|
|
v1.POST("/kyc/initiate", initiateKYC)
|
|
v1.GET("/compliance/restrictions/:investor", getRestrictions)
|
|
}
|
|
\end{lstlisting}
|
|
|
|
All routes require Hanzo IAM JWT authentication. The \texttt{owner} claim scopes all queries to the authenticated organization.
|
|
|
|
\subsection{Cron Schedule}
|
|
|
|
The 19 scheduled tasks maintain system invariants:
