## Transfer state diagrams
These diagrams show the states traversed by an asset transfer and their
relationships.
For the possible states a transfer can be in, please see the [`TransferStatus`
enum].
Issuance is not covered here, as it is created in status `Settled` right away
and doesn't go through any state change.
### Sender
From the sender's perspective, the main differences in flow are due to the
transfer being a default or a donation one and, in the default mode, due to the
confirmation from the receiver.

### Receiver
From the receiver's perspective, the main difference in flow is due to the
transfer consignment being successfully validated or not.
