Check for the Phantom provider object to detect if the wallet extension is installed for Sui dapps.
Sui support has been deprecated.
To detect if a user has already installed Phantom, a web application should check for the existence of a phantom object. Phantom’s browser extension and mobile in-app browser will both inject a phantom object into the window of any web application the user visits, provided that site is using https://, on localhost, or is 127.0.0.1. Phantom will not inject the provider into sites using http://.If a phantom object exists, Sui apps can interact with Phantom via the API found at window.phantom.sui.To detect if Phantom is installed, an application should check for an additional isPhantom flag.
If Phantom is not installed, we recommend you redirect your users to our website https://www.phantom.com/. Altogether this may look like the following:
const getProvider = () => { if ('phantom' in window) { const provider = window.phantom?.sui; if (provider?.isPhantom) { return provider; } } window.open('https://phantom.com/', '_blank');};
