Didn't you mention in one of the posts (or perhaps it was a comment you made), that there was work being done to change the API to a standard that Coinbase uses? My interpretation of that was that Hive is going to have a tough time getting on CB without making that change.
Am I understanding that correctly and how is the progress there going?
As I understand it, Coinbase likes tokens to integrate some interface called Rosetta. I haven't looked into it myself, but @howo reviewed it. I suggested to him that it should probably be supported via a hived plugin.
