When you say "commissions" do you mean Eth Gas? Which has broadly become a term for any networks transaction fees, paid to block miner/makers and which WE don't have on our feeless, free transaction network (RC excepted, but thats not really any kind of "money", and even minnows can make it with the base allotment of RC, though most get easy RC delegations from whoever told them to come here anyway so its kind of moot)

Anyhoo, yeah, the problems enter in when you have fees to use a chains tokenizer second layer to do this sort of thing. They gotta pay the gas. Which is why these sorts of Pools help, they keep the whole thing second layer and provide giant piles of middleman money to pass around when they get some from you and send it to the other person.

A do it all app, would have to talk to every chain, figure out the disparities in transaction costs, make that work somehow, even for chains that are normally free vs those that are very expensive like core Eth or even some BTC transactions and the problems in doing all this run deep, possibly insurmountable without these middle brokers facilitating things in the ways they do.

It's all very complicated and thats why crypto ain't "facebook easy" enough yet.

Thanks for betting on me, but beyond hive, I doubt I'll be of much use. I do have a line on the tool to make all our Hive auth tools work for my site at once without much effort and allow users to come in from any of them, or even add their own custom login validators to it, but beyond that, I dunno man, I just dunno how someone will connect all the chains money and make it make sense and still be easy enough to use that you don't need a technical engineering degree with a masters in finance to use it.
