RARI joins Espresso for hackathon
+Listen to the RARI Recap Pt 2
RARI is excited to collaborate with Espresso on its inaugural Build & Brew Hackathon, which launched March 10 and will conclude March 31.
Our Head of Strategy, Jana Bertram, will be one of the participating judges. It’s not too late to join!
This global event focuses on advancing Ethereum's multi-chain and intent-based future, with developers competing for a $100,000 prize pool across two tracks:
Caffeinate & Code ($50K): Deploy functional rollups integrated with Espresso's confirmation layer. Everyone who successfully completes this challenge receives a guaranteed share of the prize pool.
Cracking Composability ($50K): Build innovative applications that leverage Espresso confirmations and the Open Intents Framework to create seamless, composable cross-chain experiences.
At RARI, we're particularly excited to see projects that push new boundaries within NFT infrastructure. Espresso's confirmation layer provides near-instant transaction finality across chains, enabling a new generation of interoperable apps.

Join us in shaping Ethereum's multi-chain future.
RARI Recap # 2
Yesterday over 200 friends joined us on X as we caught up with Rarible, Eclipse chain, and a few creators to talk ETH Denver, Scope marketplace, and the current NFT meta.
47 listeners minted the POAP. One winner will get $50 in $RARI. Stay tuned for our next monthly spaces in April—we will give away another $50 in April & May, and one listener who collects at least 3/4 POAPs from February-May will get $350!
