ETHGlobal Cannes 2026 opens its doors on April 3 as the first major in-person hackathon on ETHGlobal’s packed 2026 global calendar. The event runs until April 5, giving participants 36 hours of focused building time on the French Riviera, one of Europe’s most high-profile conference destinations.
The hackathon takes place at the Palais des Festivals et des Congrès, located at 1 Boulevard de la Croisette, the same venue that hosts the legendary Cannes Film Festival each year. Participants from dozens of countries gather here to push the boundaries of Ethereum-based applications.
The Global Calendar That Places Cannes at the Centre
ETHGlobal announced its full 2026 in-person hackathon schedule in November 2025, listing five major cities across the calendar year. Cannes leads the lineup, followed by New York (June 12–14), Lisbon (July 24–26), Tokyo (September 25–27), and Mumbai in Q4.
The decision to open the 2026 series in Cannes reflects the city’s growing significance as a hub for European crypto and Web3 gatherings. EthCC 2026 also ran in Cannes from March 27 to April 5, meaning the broader Web3 community has spent the last week converging on the French Riviera for back-to-back flagship events.
Pragma Cannes 2026: The Day-One Conference Before the Build Begins
ETHGlobal structured the Cannes week with a dedicated pre-hackathon conference — Pragma Cannes 2026 held on April 2, the day before the hackathon officially launched. Pragma events follow a focused, smaller-format model designed for builders, founders, investors, and researchers who prefer deep technical discussion over large expo-style gatherings.
The Pragma series intentionally keeps audience numbers tight to encourage direct interaction between speakers and attendees. Sessions at Pragma Cannes 2026 covered Ethereum scaling, security, protocol development, and real-world Web3 applications, setting the intellectual tone for the three-day hackathon that followed.
What Developers Build at ETHGlobal Cannes 2026
ETHGlobal hackathons operate on a learn-by-doing model, placing beginner-friendliness alongside elite-level technical mentorship. Participants work in teams, receive guidance from mentors representing top blockchain protocols, and attend expert-led workshops throughout the event.
The key themes driving project submissions at ETHGlobal Cannes 2026 include:
- Zero-Knowledge Proofs and privacy-preserving computation
- AI x Crypto integrations and autonomous agent applications
- DeFi protocols and financial infrastructure
- Layer 2s and Interoperability across Ethereum and connected chains
- Developer Tools (DevTools) and smart contract infrastructure
- TEEs (Trusted Execution Environments) and data availability
- Identity, Public Goods, and Privacy & Security
The Prize Pool: Sponsors Put Real Money Behind Innovation
ETHGlobal events attract major blockchain sponsors who each contribute prizes for winning projects built with their protocols. Reports suggest the 2026 prize structure closely mirrors the 2025 Cannes edition, which featured over $300,000 in total sponsor prizes.
Key sponsor prize contributions from the 2025 edition — which set the template for 2026 — included:
- LayerZero — $20,000
- 1inch — $20,000
- World — $20,000
- Oasis Protocol — $10,000
- Chainlink — $10,000
- Zircuit — $10,000

- Circle, ENS, The Graph, Flow, Ledger, Mantle, Ethereum Foundation — $5,000–$10,000 each
The full confirmed prize pool breakdown specific to the 2026 edition is not publicly disclosed in its entirety at time of publication.
Speakers and Mentors: Who Guides the Builders
ETHGlobal consistently brings in world-class speakers across its hackathon series. The 2025 Cannes edition featured Ethereum co-founder Vitalik Buterin, Aave founder Stani Kulechov, Chainlink co-founder Sergey Nazarov, and Dapper Labs CEO Roham Gharegozlou among its speaker roster.
Reports suggest the 2026 edition maintains a similar standard of speaker quality, drawing from Ethereum core teams, leading Layer 2 projects, DeFi protocols, and infrastructure providers. Not publicly disclosed is the full confirmed speaker list for the 2026 edition at the time of publication.
800+ Attendees, 29+ Workshops: The Numbers Behind the Event
ETHGlobal Cannes 2026 expects more than 800 in-person attendees and features 29 or more structured workshops across its three-day run. Over 10 blockchain protocols actively participate as mentors and partners, offering teams direct technical support while they build.
Attendees also gain access to co-working spaces, community meetups, happy-hour networking sessions, exclusive event merchandise, and free catering throughout the event. These features make ETHGlobal hackathons attractive not only for experienced developers but also for builders entering the Web3 space for the first time.
What Comes After Cannes in the 2026 ETHGlobal Series
Teams that build standout projects at ETHGlobal Cannes 2026 gain visibility with protocol sponsors, venture capital firms, and ecosystem accelerators who actively scout at these events. Past ETHGlobal finalists have gone on to raise funding, launch products, and join major Web3 organisations.
The next stop on ETHGlobal’s 2026 circuit ETHGlobal New York runs June 12–14 at the Javits Center in Manhattan, offering the global builder community another major platform just two months after Cannes. Developers who miss Cannes can register interest for New York through the official ETHGlobal website at ethglobal.com.
