How Wats Works: 3 Simple Steps
There are two components at play in the Wats Wallet.
The first component is the Wats device—a pack of two or three Wats cards. The second component is the Wats mobile app, which is available on iOS (soon) and Android. You can download it on any mobile device with an Android operating system higher than 6.0 or iOS 15.0 and higher with full NFC support, except iPhone 6/6s and iPhone SE (1st generation).
Please note that iPhone 7/7 Plus and some Android models do not have full NFC support. In this case, backing up your private keys on your phone is not available. You can use any other phone—iPhone 8 and up or Android 6.0+ with full NFC support—to create a backup and continue using the app on your device.
How these two components work together.
Wats Device
Wats cards have an inbuilt secure element chip that functions as a microcomputer. When the device is manufactured, the chip generates its own key pair: the Kcardpriv private key and the Kcardpub public key.
These keys are unique to each Wats device and are not connected to the future user's wallet. They're only required so that the Wats device can prove its authenticity and tell the app that Wats manufactured it.
The Wats App
The Wats App displays the functionalities of the Wats wallet, including user portfolio and user controls for managing cryptocurrency.
How Wats Wallet interacts with the mobile app
Wats Wallet connects with your mobile app using Near-Field Communication (NFC). NFC is a wireless technology that enables devices to communicate when placed within a few centimeters of each other through magnetic field induction.
Get started in 3 steps:
Download the Wats app from the App Store (soon) or Google Play.
