When I first came across OneDex, I was quite fascinated by the way they intend to decentralize the whole process of trading difference tokens or crypto currencies of different chains. This idea alone is enough to draw out liquidity from big names in the decentralized space, but it does seem the project Developers do not understand what they had. The project couldn't see to fruition its goal as it's roadmap ended at 2019. When I even came to the website, which works very well, I was hoping to see that it doesn't work and so made me rethink it's stance as an inactive project.
On the website, I could see the picture of the developers and their team members which provides room for doubt. I did a lot of skimming and scanning still couldn't find any relative reason to why the platform is inactive. I tried looking for a Dex platform to see if maybe any of his project were ever launched according to its road map which also didn't yield any fruits. To end this, I will say that this project is inactive but I really hope it bounces back to life or another project takes its place.
