Excuse me, did this actually happen to you, or is it just a hypothesis?
If this actually happened, it's a serious matter, and the service must prevent such incidents from occurring, as this would quickly damage the site's reputation. If this is an example, I believe OP should clarify, since he claims the service is decentralized and the user has the access to obtain the secret key to the deposit address.
It's just a hypothesis and a 'what if' question. The address I shared in my previous post is an actual address that the exchange generated for me where I should deposit my bitcoin if I wanted to do a swap. I am asking OP where would I get the keys to that address.
When you exchanged on EXCH, did they also give you the private key of your deposit address?

eXch has nothing to do with CCE.Cash or this discussion. I know why I am asking the questions I am asking. eXch didn't claim it was a non-custodial and decentralized exchange. CCE.Cash says it is. I am asking OP to explain how it works. If it's non-custodial, I am asking where the keys are to the deposit addresses. If it's decentralized, I am asking how to perform swaps when the website is offline and how to connect P2P to other market participants. According to OP, transactions are conducted directly between two parties. Meaning, I (the buyer) am connected directly to the seller. I want the OP to explain how that connection works if the CCE.Cash service is down?
