As of Phantom v22.04.11, iOS and Android apps can now natively interact with Phantom through either universal links(recommended) or deeplinks. We refer to both of these workflows collectively as "deeplinks".

In addition to these provider methods, Phantom also supports Other Methods that are accessible via deeplinks. Specifically, users can open web apps within Phantom's in-app browser via the Browse deeplink.
