@minespider/core-bundles/dist/StorageBundle/Business/StorageFacade.js

A high-level SDK for Minespider Core. It abstract the low-level features from the core SDK for a more high-level usage such as DAPPs. Some of the features are 1:1 with the SDK some others abstract some low-level interactions or multiple actions
