    Function getStatementStore

    • Get the host API statement store when running inside a container.

      Returns a statement store with subscribe, createProof, and submit methods that communicate through the host's native binary protocol — bypassing JSON-RPC entirely. Returns null when @novasamatech/product-sdk is unavailable.

      Returns Promise<
