# SpherePay Concepts and Reference Data Overview

> Core mental models and reference data for building on SpherePay — onboarding, transfers, automation, supported rails, and operational details.

The Concepts section explains how SpherePay's building blocks fit together. Read these pages before integrating — they cover the platform's two onboarding models, the transfer lifecycle, the automation primitives, and the reference data (countries, assets, codes) you'll wire up against.

Not sure which build path to follow after discovery? Read [Implementation Guides](/implementation-guides/overview) to route to the right implementation pattern before choosing a [Solutions](/solutions/overview) guide.
