The Composable Payment Architecture (CPA) is Hellgate's approach to building payment systems from independent, interoperable components rather than one monolithic platform. Instead of adopting a single vendor's bundled stack, you compose only the services you need – a vault, an orchestration layer, a fraud engine, a PSP abstraction – and snap them into your existing infrastructure.

CPA is not a product; it's an architectural model. Each Hellgate service (Guardian, Hub, Specter, Link, Commerce, Pulse) is built to CPA principles: standalone, composable, and API-driven. Enterprises and platforms use it to own and control their payment flows without vendor lock-in.
