NOVIG_HOST. Set it once:
Paper is our play-money exchange. It runs the same API as Production, without the location check.
In both environments, you create a key on Profile.
In Paper, use Profile on paper.novig.com. In Production, use Profile on novig.com.
The websocket uses the same host as REST. On Paper, that’s
wss://api.paper.novig.com.
Set up a Paper account
Paper has its own web app at https://paper.novig.com. Every account starts with $10,000 in play money, so you can trade without risk. Paper skips the identity check. It fills in a simulated profile for you, so you never enter your real details.1
