Open the Phantom website (phantom.app) on any of the four supported browsers(Google Chrome, Brave, Edge, or Firefox). There is an ‘Add to Chrome’ button(If you’re using Chrome). Once you click that, the website ushers you into a web store containing a number of plugins. Click ‘Add to Chrome’ on the Phantom plugin, and it downloads the wallet(about six megabytes or so). Once done, it installs automatically and can be accessed from the list of downloaded browser extension.
