# AQUA App Overview

AQUA App is the flagship implementation of the Application Layer. It is designed as a stablecoin-powered financial application that provides user-facing access to payments, transfers, and yield.

The purpose of AQUA App is not merely to expose protocol functionality in interface form. Its purpose is to provide a practical financial experience that connects users to the broader Ontorium Stack.

In this structure, AQUA App sits downstream of the Asset and Financial Layers. It does not replace them. Rather, it serves as the interface through which users can access the value created by those layers.

As Ontorium expands, the Application Layer may include additional interfaces, services, or distribution channels. AQUA App is the current flagship implementation, but the layer is intentionally broader than any single application.
