You can test the bridge now on Goerli at https://dzimbeck.github.io/test-page

Currently I'm working on tying those last parts back to Halo. With the python pseudocode Yshurik is tasked with doing the c++ side. It should be this year for sure. However I can't speak for his schedule or hours. Either way, you can see for yourself this is in the final phases of testing. However do consider there will probably be a c++ client testnet phase. But that can be somewhat short because I can review that code anyways.

NightTrader as a friendly reminder is NOT a project that I've coded, it's a decentralized exchange coded by Yshurik so I have not much control over that. It is based on ideas I shared years ago with sighashes and threshold sigs though. I gave the name to Alec because we have known each other since Blackcoin days so he is the one that knows whats going on with it. However, from watching the progress he made some good breakthroughs I still think winter is a bit early I anticipate it moreso in Q1 although for that to have a fully fledged GUI that rivals something like Kraken may take longer.
