Cypherpunk Speakeasy v0.0.1

Powered by the Burner Wallet 2.0

The narrative was simple: we are in a future time where the US dollar is hyperinflated and the credit card companies have long since passed. In order to partake in the delectable libations at this week’s Boulder Blockchain Meetup, you had to pay with a cryptographically backed currency.

Thanks to the simplicity of the 🔥Burner Wallet, participants could easily exchange xDai for beers with the simple scan of a QR code right in their mobile phone’s web browser; no seed phrases, no wallet downloads.

There was no need for an expensive POS system either. The bartender just pulled up https://xdai.io on the bar’s iPad and voila she had a wallet where patrons could send value and she could track sales.

We spent a lot of time on a full redesign. It is still a work in progress, but it’s really starting to look like an actual wallet!

We also got some real world user testing, this is super valuable for making a product with good UX. The main takeaway was the Burner Wallet is simple enough that it could be the path to mainstream adoption. Nearly all of the 40 some participants were able to create a wallet and move xDai simply by visiting a website. How cool is it that every beer you see in the event photos was purchased with crypto!? You can even view all the transactions to the bar’s POS iPad Burner Wallet on blockscout.


Along with the style update we’ve added a lot of new features and improved security. If you would like to join our growing developer community checkout the repo and bounties on Gitcoin!

We also just launched a Gitcoin Grant for the Burner Wallet. We would love to have recurring support for more bounties and user testing.


This was such an awesome evening. A room full of people quickly transacting with crypto; actually using this cool technology of ours. The only other time in my life I have experienced something like this was at Paralelní Polis in Prague. Not everything was perfect though. There were certainly a few bugs in the wallet that we still need to work out. For instance, some phones would only use the front facing camera so you had to get weird to send funds:


Mad props to Brian Ethier, Jonathan Palmer, and Michael Green for organizing the event. Also, a big shout out to CasaHODL for sponsoring the first beers:
