Welcome to SCRF @tarun, it’s awesome to see you here!
I was actually just about to dive into the new publication – it was featured in last week’s Research Pulse (a curation of the top papers posted that week).
Privacy in pseudonymous blockchains will always be a touchy topic given the wide range of attack vectors both at the tx graph layer as well as the P2P network layer, but I really like the proposed URE approach. As you point out, it likely won’t get much better than that.
URE also seems to be highly complementary to strategies that decrease the profitability of Sandwich Attacks, whereby a single swap is split into many using a relatively straigtforward algorithm. Is this something you have considered in URE’s design?
