The Patchcoin Claims Dashboard has been updated to include bulk checking for peercoin addresses which may have not yet been claimed. This is useful to ensure dust addresses have been claimed.
It is available here: Patchcoin Claims Dashboard
The Plain Address List tab takes a single peercoin address per line to check for.
The Pasted listreceivedbyaddress.json tab takes the output of the listreceivedbyaddress command from the peercoin client.
You can get the contents of that file by opening your peercoin client → selecting Window → selecting Console → and finally running listreceivedbyaddress 0 true.
While the site is run entirely local and the contents of the listreceivedbyaddress command are generally safe to share you may wish to clean the output of any other field but address before pasting it anywhere.
