You are able to directly send Bitcoin or Bitcoin Cash to the contacts on your mobile device, provided that they are also a BTC.com wallet user and have also enabled this feature.
To enable the feature, go to → Settings. First, set your phone number in the wallet and verify it via the SMS code. Next, go to → Contacts, and enable contacts.
To make a payment, go to → Send in your wallet, enter the required amount, simply select a contact from your phone's address book and click “Send.”
We find the wallet associated with your friend's phone number and create a new address to which you can send Bitcoin / Bitcoin Cash. If your contact is not a BTC.com user, click “Tell a Friend” and send him or her an invitation, so you can transact with each other easily!
