The Seven-Phase Transport Lifecycle
From submission to settlement: the seven phases every bundle moves through inside the Transport Layer.
About this course
Vertical stack context: DOSFIUniversity (research) → DOSFI Academy (this course) → MeshNativeExchange (publishing & monetizing). Students progress from Learning → Building → Publishing → Monetizing. Every bundle follows the same seven-phase lifecycle through the Transport Layer: Submit, Validate, Enrich, Route, Meter, Transit, and Settle. This course walks each phase from the developer's perspective, showing what you can observe through the public SDK at each step. By the end you will be able to describe a bundle's full journey from your app calling the Transport API to MeshNativeExchange closing the economic loop -- all through public observability tools.
