   * Making zaddr transactions are slower, taking a few seconds instead of a few milliseconds
   * Shielded transactions do not show the sender address, receiver address or amounts on the public explorer. You will need to use local RPC methods such as `z_viewtransaction` to see those details
   * Shielded transactions are larger than transparent transactions, because more data is stored
+  * RPCs which work with zaddrs usually begin with `z_` such as `z_listunspent`. The very common `sendmany` RPC is called `z_sendmany` for zaddrs
