However this is No Account exchange.
It is a no account exchange and that's fine. That's the standard way that instant exchanges operate. What I don't think is fine is claiming to be non-custodial and decentralized. CCE.Cash still claims that and it's written in their correspondence here with the community.
The difference between CCECash (semi-custodial exchange) and non-custodial wallets lies in their core functionality, custody model, and user control.
CCECash focuses on cryptocurrency exchange services for asset exchange/trading (e.g. BTC to ETH). Acts as an intermediary to facilitate transactions, but temporarily holds user funds during the transaction. Users must send cryptocurrency to a CCECash address to initiate the exchange. During the processing, CCECash controls the funds. Users rely on CCECash to complete the transaction.
CCECash:..Suitable for users who prioritize speed rather than full self-custody.
CCECash is a temporary custodian for swaps and is more suitable for fast transactions.
Can we stop beating around the bush please and call things the way they are. You went from claiming you are non custodial to calling yourself semi-custodial, and a temporary user-funds-holder. You are custodial. That's it. You and your intermediaries have custody of the coins until they get deposited into user wallets. The users don't have control of their money until the exchange is over. That's how a custodial service operates. It's based on trust. Trust that the custodian will do the right thing and exchange the funds and give up custody of them.
I see no problem in an exchange being custodial as long as they are honest about it. You haven't been honest. You are neither decentralized nor non custodial and the question is how long are you going to claim that you are? You are new on the forum. Be honest with your potential customers to be able to build trust. Personally, I would never try a service that isn't telling me the truth. Everyone else can make up their own minds.
Additionally, if you were non custodial, you and your intermediaries wouldn't be able to freeze coins and request KYC. Your users could simply import their keys into a real non custodial wallet and forget about you and the KYC requirements. But they can't do that because they don't have custody of the coins. You have.
