When it comes to on-chain privacy, the biggest issue is not the technology itself, but the cost of messing around with it.

To achieve true privacy, the traditional approach has been nothing more than—create a new wallet, memorize the seed phrase, switch back and forth. It sounds simple, but most users get confused after just one attempt, and in the end, they choose "Anyway, everything is transparent." High barriers and complicated processes are the real reasons why privacy solutions can't gain widespread adoption.

Now, some new solutions are starting to consider the user perspective. For example, no need to create additional wallets, no need to switch networks—just use your existing Metamask, Rabby, or Phantom, and you can perform private transfers on mainstream public chains. Using existing infrastructure for privacy, eliminating the cumbersome pre-steps.

What is the value of this approach? Lower the usage barrier, making privacy no longer a "hassle," but an option that can be done with a single click. Users no longer have to weigh privacy versus convenience—both can be achieved.
