pub struct BlockifierStateAdapter<T: Config> { /* private fields */ }
Expand description

Empty struct that implements the traits needed by the blockifier/starknet in rust.

We feed this struct when executing a transaction so that we directly use the substrate storage and not an extra layer that would add overhead. We don’t implement those traits directly on the pallet to avoid compilation problems.
