Set-up tips, key concepts and how to build with them | Substrate Seminar
107In this seminar, Parity Developer Advocate Sacha Lansky will walk through some of Substrate’s key concepts by diving into some intermediate level how-to guides. In doing so, he plans to showcase different implementations of certain concepts and their APIs, with a focus on how to write pallets that are customized for a particular use case. Topics will include: pallet coupling, origins and runtime configurations.
