It does, but the signing part has been in NAK for ages, and i had no issue creating various libsecp256k1implementations using whatever language under the sun (well....eventually i had not problems :P) The tricky part is perhaps the remote signing part, which i did implement via that amber-fork and that works. I also implemented into NAK and gave it to the jungle spirit to have a look, i suppose it works but have not tested it. Il drop the standards the robot came up with for this stuff soon so y'all can have a look at what is sensible. Finishing up a project first and then il clean up my digital desk and present all of it
