    pub(crate) fallback: RuntimeApiStorageOverride<B, C>,
}
Expand description

A storage override for runtimes that use different ethereum schema.

It fetches data from the state backend, with some assumptions about pallet-ethereum’s storage schema, as a preference. However, if there is no ethereum schema in the state, it’ll use the runtime API as fallback implementation.

It is used to avoid spawning the runtime and the overhead associated with it.
