ETH Waterloo Winning Apps

· 3 min read

Last Saturday, we had the incredible opportunity to attend ETH Waterloo. For those who may not know, Vitalik went to college in Waterloo, and the first ETH Global event was also held there. We couldn't help but feel the infectious energy and excitement for the future of blockchain technology.

XMTP Labs team at ETH Waterloo

We interacted with many passionate and innovative teams, each expressing a keen interest in building with XMTP: the protocol & open network for secure, private messaging. The response was overwhelming: we had 16 submissions, the most we've ever had!

We even decided to run our own "Bodega" at the event as a way to introduce more people to portable, secure messaging.

We gave away toothpaste and toothbrushes in exchange for receiving messages using our flagship ecosystem app Converse. Over 100 people sent us requests!

The last day we decided to catch a local showing of the BlackBerry movie. For those of you who may not know, BlackBerry has deep roots in Waterloo and, incidentally, is where our CEO’s @shanemac's first startup had its journey culminate in a buyout.

Entry to Princess Twin Cinemas

The movie was nothing short of incredible and we recommend you all to give it a watch when you get a chance. It truly was an intriguing glimpse into a piece of tech history and the entrepreneurial spirit that drives the ecosystem.
