# System Architecture & Topology

To demonstrate the robustness and scalability of the OmniPact system architecture, this section describes it using the Layered Architecture Pattern. We decouple the complex protocol logic into four functionally independent layers, with each layer interacting with the upper and lower layers through standardized interfaces. This design not only ensures the modularity of the system but also reserves interfaces for future cross-chain deployment and privacy upgrades.
