zthomas High five Thomas. This is a really great first release.
While a Chrome extension might not be as robust as a full fledged desktop app, I feel like this is a good path forward as it does a solid job of bridging the gap between security and convenience. For developers being able to pass context from a webpage to a payment app without requiring the user to do anything reduces a lot of friction.
Obviously there's a dependency on the user running Chrome and there's still a gap for mobile users, I'm really excited about this though. I'll implement it on my site, and I'd love to help out in other ways where I can. Good stuff!!
