…llet.
This makes it easy for code reuse throughout an application or even creating an instance inside of a hook. I've been using this in my react native expo app for the last month and it works well. I create an instance inside of a Context component and my entire application has access to interact with Phantom and get notified of changes(connects, disconnects, etc...)
