We wanted to do something involving bitcoin and chrome extension, and came across this idea.
What it does
Allows you to shop online on a site that doesn't traditionally accept bitcoin. When you make a purchase, it sends the bitcoin to our coinbase account, and we issue you a prepaid capital one Nessie credit card that you can use to make your purchase. No annoying 10-minute confirmations!
How we built it
We have a node.js backend on heroku running the API integrations. We use the coinbase and Nessie APIs to handle the money, and deliver the app via a chrome extension. Firebase stores a hashmap between nessie customer ids and coinbase customer ids.
Challenges we ran into
API integration issues, Implementing OAuth2,
Accomplishments that we're proud of
Node.JS integrations; pratical application, simple and elegant
What we learned
How to use these APIs, make a chrome extension.
What's next for Bitcard
Use of other cryptocurrencies, integration with other online wallet providers
