Grade an IoTeX address from facts you can document, and write the grade in plain words. File it under the 0x form.
What moves the grade
An OFAC hit settles the question and raises the grade at once. A wallet with a large outgoing count and a small balance looks like a pass-through and needs a timeline before you score it. A wallet with zero outgoing transactions is only partly described, because deposits are not counted.
Writing the grade
Lead with the address and the check time. Put the balance next to the grade. Say which inputs came from the free check and which came from your own reading of the public record.
