Hello, i’m victor.

In near day, there were lots of transaction on Network. In my situation, i need function that can find the change history of an asset based on a checkpoint.

Now, i call a getCheckpoint func and get list of digest, after that i call getTransactionBlock parse balanceChanges. As you know, in near day lots of transaction make lots of api call. So Could you make some API func for parse balanceChanges on a checkpoint?

thank you
