To send or request money from friends who have a Broad account, open the app and go to "Transfers" and select "Send" or "Request". Then select the person to whom you want to send or receive money.
If it is the first time you are transferring money to someone through Broad, the app will ask you to authorise access your phone’s contacts so it can show you which of your contacts have a Broad account.
If the friend you want to send or request does not have Broad account yet, remember to invitem them to join Broad. See how here.
