Grade a zkSync Era address from facts you can document and write the grade in plain words. File it under the address together with the network name.
What moves the grade
An OFAC hit settles the question and raises the grade at once. A wallet with a high activity count needs a timeline before you score it. An empty wallet and an active one carry different weight, and the check separates them by balance and count.
Writing the grade
Lead with the address and the check time. Put the USD balance next to the grade. Say which inputs came from the free check and which came from your own read of the explorer.
