Required Methods

fn pre_dispatch_tx_hook( &self, tx: &Transaction<Self::Context>, working_set: &mut WorkingSet<<Self::Context as Spec>::Storage> ) -> Result<<Self::Context as Spec>::Address>

Runs just before a transaction is dispatched to an appropriate module. TODO: Why does it return address? Does it implies that it should do signature verification. Can other code rely on that assumption?

fn post_dispatch_tx_hook( &self, tx: &Transaction<Self::Context>, working_set: &mut WorkingSet<<Self::Context as Spec>::Storage> ) -> Result<()>

Runs after the tx is dispatched to an appropriate module. IF this hook returns error rollup panics
