Adding a custom logic to runtime

Customize the pallet and add the custom logic.

Last updated 5 months ago

Runtime is where you register a new pallet to add customized logic to your runtime. Runtime is a collection of pallets. For example, core pallets for all Substrate blockchain can be listed:

  • Executive pallets: Orchestration of calls into pallets from the runtime

  • System pallet: Core types, system utilities and event handling.

  • Ecossytem pallets: Pallet assets, pallet balances, pallet nfts...
