I can factor out the aim and purpose of this thread, because as far as I know such features to track wallet and know their balance status is very easy and just let me other have referred you it will not amount to be a service that you can call a business just tracking wallet information and status, this could be done easy and freely from coin Explorer and the rest of them, although it will help in some ways of the job have no clue of how to check those wallet infos online by themselves but I don't think anyone will be ready to pay a fee for such services.
