A weekend Ethereum hackathon at the Palais des Festivals in Cannes.
ETHGlobal Cannes 2026 was a three-day in-person Ethereum hackathon at the Palais des Festivals et des Congrès in Cannes, France, from 3 to 5 April.
ETHGlobal runs Ethereum hackathons around the world, where developers form small teams and build a working project over a weekend. The Cannes event took place at the Palais des Festivals et des Congrès, the venue of the Cannes Film Festival.
Teams competed for prizes offered by sponsoring protocols, with judges and mentors from groups such as the Ethereum Foundation, Ledger, Circle and Optimism. The finished projects are listed in ETHGlobal's public showcase. A one-day Pragma summit was held on 2 April, the day before the hackathon.
