Cointoolkit will work with the information within the transaction, it does not have any provider configured to load external data for PPC. You can see and change all that in the settings tab…
You will be able to use it to verify and sign the transaction, but you need to input unspent inputs manually in order to create a new transaction.
The code is ready for anyone to add custom providers easily, but no contributions have been made.
I will add a provider for PPC data (suggestions of stable PPC blockexplorers with a good API to use for this are welcome), but keep in mind that I am doing that on my limited unpaid free time.
