Wallet

class Wallet

A wallet (name may be temporary) wraps a set of states that are useful for us to keep track of, for instance, because we own them. This class represents an immutable, stable state of a wallet: it is guaranteed not to change out from underneath you, even though the canonical currently-best-known wallet may change as we learn about new transactions from our peers and generate new transactions that consume states ourselves.

This abstract class has no references to Cash contracts.

states Holds the list of states that are active and relevant. Active means they havent been consumed yet (or we dont know about it). Relevant means they contain at least one of our pubkeys.





Types

Update data class Update
