I tried this today and it is so dope. You can download an iOS app which is from what I understand self-custodial. And then you can just receive regular ETH to the wallet, but you can shield it, and so then it becomes untraceable onchain, which is so great when you need to transfer between accounts that you don‘t want to comingle. What makes me excited about this is that it seems to be a full fledged wallet, so I kinda want them to build more around smart contract accounts so that maybe one day we can JUST use those for most of our activity, and that we only go onchain when we want to.
Looks cool! Going to try.
