It's been an amazing weekend in the city of New York! 🗽 Lots of people chose XMTP for building and sending secure messages, from Airtag trackers to DeFi notifications. We also had a great run on our newest version of the CryptoCornerStore.eth, in partnership with ENS and powered by Chainjet.

The CryptoCornerStore was a huge success, with over 50% of devs placing orders on the XMTP network. We had a lot of fun with the store, and we hope you did too!
