How about use and improve the open WebVR standard that is built-in to browsers? Bring back the feature that allowed for portals with transitions between sites without exiting VR.

We don't need Meta, just need to improve VR in browsers a bit, maybe add something to websites that makes it a little easier to integrate cryptocurrencies. Although there is nothing really stopping it now.. maybe some enhancements for integrating cyrptocurrency wallets into VR more securely.
