Would be cool to see Keychain becomes the " payment Defi" app for Hive. But for that a Fiat gateway would be needed.

Thats pretty much the bottleneck of all crypto. "we dont want fiat" is what they say, what they mean is " we cant do it because of rules".

Thats IMO worth solving and would bring keychain in a unique position ( + revenue stream).

the " Aggregator architecture" is something for outside hive right? Since on Hive there is no pool to clear things in?
