Cartesi Ecosystem Recap #6

Newsletter/Feb 9, 2024/Siannie Quartero

February 9th - We did it, we made it through the 4 months of January! 🎉 Congratulations everyone. Is it just us or does January always feel incredibly long? Or… a lot has happened in January that made it feel long, such as onboarding devs during the Cartesi x Web3Bridge Masterclass, Aetheras launching their playable demo of Dazzle, and integrations continuing being strong together with other epic Web3 players such as Syscoin, Celestia & Espresso!

Have you checked out the updated transparency report? The Cartesi Foundation is one of the many teams, units, companies, and individuals that advocate the ecosystem’s collective vision and contribute to the development and adoption of the Cartesi technology. You can read about the ways in which the Cartesi Foundation supported and contributed to the ecosystem in the latest transparency report for 2023.
