ohh ok now i understand.this was the peace i was missing.thank you.
and last question,this is the app right ?
xrpl labs ou.thats the one ? beacuse this app can easily be copycated with malicious intentions.thats one of the reasons i am scared of mobile apps and the second is that i lost some coins(not xrp) in a malicious mobile app after i read people recommand it .to me 99% of them are malicious.just want to make sure i dont do the same mistake again.thanks
