+  | `err: undefined` is like looking |
+  | for a tx with no err             |
+  | so you can also search txs that  |
+  | dont have something as well by   |
+  | setting the value as undefined   |

   this is for things like filtering a the tx list
   for only tx's from 1 account
   or for filltering for all txs from one account
