abstract class BaseDriver extends Flusher[Transaction] with NamedLogging with FlagCloseable with NoTracing with HasFlushFuture with Factory
Shared implementation between master, trader and issuer roles.
The base driver contains the shared code between each role. In here, we setup the connection, read the ACS on startup, initialise the driver and provide a set of utilities that all roles will need (such as submitting and tracking submissions or dealing with pending contracts)
We also implement here the basic nanobot update logic.
