Hi @ngqinzhe Thanks for the MR, I've also been trying to test the same but can't get K to compile from source on my machine anymore for some reason. EDIT: because I hit #1166 too, didn't notice other people were experiencing the same too. how did you get over it, can you share the fix for that too? There's another update coming at the end of this month, the API addresses will change, if you e-mail clientservices at coinbase dot com you can start using the new API to test. Can you throw that in too so when we get @ctubio attention he can merge both? Thanks a lot.
