@ethereumjs/common / StorageRange
Object that can contain a set of storage keys associated with an account.
• nextKey: null | string
The next (hashed) storage key after the greatest storage key
contained in storage.
• storage: Object
A dictionary where the keys are hashed storage keys, and the values are
objects containing the preimage of the hashed key (in key) and the
storage key (in value). Currently, there is no way to retrieve preimages,
so they are always null.
▪ [key: string]: { key: string | null ; value: string }
