As per recent update (Shurli (Subatomic Swaps) application weekly update — 29 May, 2020), I think Shurli is ready to be treated as first proof of concept application for doing subatomic swaps.
At the moment, it’s still very early stages, but trying the so far developed application will help getting some feedback from the users which will help shape the next UI/UX iterations.
We’d love to hear feedback on Shurli from you. Please fill this form to get invited to the test group: https://forms.gle/YMUowmMRwspis4jd7
Looking forward to hear from you.
