* List all transactions related to the given seed, since the given birthday. This begins by
|
|
* downloading any missing blocks and then validating and scanning their contents. Once scan is

|
* complete, the transactions are available in the database and can be accessed by any SQL tool.

* By default, the SDK uses a PagedTransactionRepository to provide transaction contents from the
|
|
* database in a paged format that works natively with RecyclerViews.
