Framework for Runtime Aggregation of Modularized Entities (FRAME) is a runtime framework used by the Substrate application and blockchain development paradigm, which was created and designed by Polkadot. FRAME is a set of modules and software libraries that simplify runtime development. Within Substrate, these modules are called pallets and they host the domain-specific logic needed to allow a blockchain's runtime system to operate.
