Thanks for the information. I don't really check Chaincase development since i don't use any iOS device. I guess there aren't any alive alternative coordinator which is based on WabiSabi CJ protocol.
I don't think Chaincase should be focusing on making yet another wallet. They should put all their efforts on their coordinator and then encourage users to connect with existing wallets (for example Sparrow Wallet and Samourai. Possibly even Wasabi minus zksnacks).
The main coordinator run by ZKSnacks submits inputs to a chain surveillance firm.
Are these claims true? How can a privacy-enhancing service provide data to parties trying to reveal identity?
They announced that they would do that. It's yet to be seen whether they'll follow through at the end. But I still would not risk using it.
