Grade a Merlin Chain 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. An address with no activity and an address with a long record deserve different weight, and the free check separates them through the activity count. The balance sits next to it as context.
Writing the grade
Lead with the address, the network 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 explorer.
