Using Metamask is much better than typing your private keys to import in DDEX. If you are using Android phone, never install unknown apps.. never root your android phones.
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?
