\section{Introduction}

\label{sec:intro}
% ============================================================================

The issuance and trading of digital securities requires infrastructure
that spans identity management, cryptographic key management, API
gateway services, data persistence, and regulatory reporting. Building
each component from scratch would duplicate capabilities that already
exist in production within the Hanzo platform.

Hanzo has operated as an AI-powered commerce and infrastructure platform
since its founding (Techstars '17), serving thousands of applications
through its unified service stack. The platform provides five core
services relevant to digital securities:

\begin{enumerate}[leftmargin=1.4em]
    \item \textbf{Hanzo IAM}: Identity and access management with OIDC,
    OAuth 2.0, and org-scoped permissions.
    \item \textbf{Hanzo KMS}: Secrets and key management with
    envelope encryption.
    \item \textbf{Hanzo Base}: Application runtime with embedded
    SQLite (local dev) or PostgreSQL (production).
    \item \textbf{Hanzo Gateway}: API gateway with rate limiting,
    request routing, and TLS termination.
    \item \textbf{Hanzo Webhooks}: Event delivery with guaranteed
    at-least-once semantics.
\end{enumerate}

ArcaLabs consumes these services to build its digital securities
platform without reimplementing foundational infrastructure.
