I've been using dex exchanges like ddex, switcheo. They asked to connect wallet through metamask or trust wallet, I'm an android user so I'm using trust wallet to use these exchanges, i wanted to ask when we connect our wallet to a specific exchange is there any possibility to stole funds anyhow?
It depends which exchange do you mean. Off course we can not say all DEX's are safe. But I trust with Etherdelta. I never experience any bad issue.
