FraxBUILD Hackathon Concludes: Here Are Our Winners!

The first FraxBUILD Hackathon has proven to be an incredibly successful effort in bringing together builders across DeFi to contribute to the growth of the Frax ecosystem. The event came at a time of great fanfare for Frax. The protocol taking major steps on its road to decentralization with the deployment of FraxGov and a myriad of upcoming releases including Frax v3, frxETH v2, BAMM, and of course Fraxchain. As Frax Co-Founder Sam Kazemian said recently in a Twitter Space, “the next year of shipping for Frax is going to look like the past year that Frax has been slacking. With vibes high and excitement evident for the ecosystem, developers inevitably were attracted to FraxBUILD, which offered them the perfect opportunity to explore Frax adjacent projects.

Our collaboration with Dorahacks for the hackathon allowed us to host a variety of workshops and office hours where hackers were able to interact with the core dev team and even get tidbits of alpha along the way. Most notably, during the first workshop back in June, Sam Kazemian presented the full architecture of frxETH v2, the first lending market for validators. Entries flooded in with hackers competitiing in the categories of product expansion (build on top of Frax products), consumer adoption (build Frax products for end users), and data analytics (build dashboards keeping track of the Frax protocol and ecosystem on-chain).

Methodology and Winners

For the judging, we were able to band together an impressive list of individuals including members of the Frax Core Team (Travis Moore, Nader, and Dennis), Redacted Founder 0xSami, and myself (the least impressive) to go over the final list of entries. Applicants were judged in four different categories including business model, innovation, technicality, and alignment went Frax.
