So their solution is to not split the transactions, and with the help of tools such as, send/track/visualize transactions that happen and are replayed on the 6+ different chains that might emerge as a result of the fork.
Why Splitting Your BCH Coins IS a Good Idea in the Long Term

That’s not what do (read the documentation please…). We just relay (and not replay) your transactions to all nodes so you don’t have to maintain your own nodes yourself (ABC, SV, NayBC, BU, bchd) in the case you want to not be impacted by blacklisting strategies. We also provide a way to search within all forks transactions by hash and check where is what transaction. We don’t replay and sign transactions for our users. We process the transactions as you sign it, splitted coins or not, to the nodes you select.
