2. rescan             (string, optional, default="whenkeyisnew") Rescan the wallet for transactions - can be "yes", "no" or "whenkeyisnew"
3. startHeight        (numeric, optional, default=0) Block height to start rescan from

Note: This call can take minutes to complete if rescan is true.

Result:

  "address" : "address|DefaultAddress",    (string) The address corresponding to the viewing key (for Sapling, this is the default address).
}

Examples:
