I think by the time ONT arrives we will see a new update NEON wallet which shows the ONT token in it. And same for Neotracker.io I imagine, so you'd be able to get the hash from there once they list it. Ontology is a huge part of the NEO ecosystem so I have no doubt they will enjoy full support asap, but we'll have to wait until the actual ONT token is called into existence I think
