🎡 A World’s Fair for Ethereum with La Rural as the Schellingpoint

For the first time, Devconnect introduced a World’s Fair-style experience, anchored entirely within La Rural, one of Buenos Aires’ most iconic venues, where everything was brought together into a single, immersive environment.

Inside La Rural, attendees could explore:

• 8 themed districts: DeFi, Privacy, L2s, Decentralized Social, Hardware & Wallets, AI, Gaming, and Art
• 80+ exhibiting teams showing real, working Ethereum applications
• 15 Community Hubs organized by ecosystem groups
• 40 events run by independent teams
• Discussion corners, coworking zones, and bookable meeting rooms
• Onboarding stations for newcomers
• Food trucks accepting crypto payments
• Live music, a cinema, and a soccer pitch with tournaments

It turned Ethereum into something you could walk through. People tested applications, played onchain games, tried new wallets, paid with crypto for food and drinks, explored AI workflows, and met the teams building on Ethereum today.

📲 The Devconnect App: the guide to the World’s Fair

The entire experience was supported by the Devconnect App, which helped attendees navigate the massive venue, view programming, build personal schedules, pay with crypto via the integrated wallet or add their own, complete quests, discover new applications, and collect POAPs on the way. We collaborated with multiple web3 projects integrated into the app: Para, SimpleFi, POAP, WalletConnect, Base, Zapper, Zupass, AT Protocol, Peanut, and ENS.

App stats

• 9,000+ logged-in users
• 16,000 POAPs minted
• 14,000 World’s Fair quests completed
• Crypto payment activity through SimpleFi

🇦🇷 Local energy and impact

Many visitors fell in love with Buenos Aires, with the spring vibe and lively streets, the mate culture, asados and steak, ice cream, the football energy, street art, and the surrounding nature. Some even stayed well beyond Devconnect.

Buenos Aires was the perfect location for the first Ethereum World’s Fair, with Argentina being one of the most active crypto markets in the world, with about 20% owning crypto, using it for savings, hedging against inflation, access to lending, and stability. Across the city, many vendors accept crypto for payments, and this familiarity made Devconnect feel at the right place at the right time. Devconnect itself was also shaped by the contributions of the local and regional Ethereum communities:

☀️ ETHCon Buenos Aires

ETHCon was one of the major Devconnect events and was organized by the local communities SEED Latam, Crecimiento, Ethereum Argentina, ETH Kipu, Mujeres en Cripto, and multiple regional partners.

• 4,000+ attendees
• 60+ speakers, including Vitalik, Santiago Palladino, city and Ministry of Education representatives, and leading companies like Mercado Libre, YPF, and Fiserv
• Talks and panels exploring Ethereum’s impact across finance, gaming, AI, art, education, and public infrastructure

🦙 Destino Devconnect

Beginning in April 2025, we supported local initiatives through Destino Devconnect, a grants round designed to accelerate regional adoption ahead of Devconnect.

Results:

• 100+ supported events
• 14 participating countries across LATAM

🎓 Universities and students

Devconnect included one of the largest student and academic components in EF event history.

• 3,000+ local school students attended via a partnership with the Ministry of Education
• 45+ universities were involved
• 8 university-led sessions happened throughout the week at La Rural

Devconnect is built on community contributions:

• 200 volunteers helped make the entire week possible, coming from 40 countries, with 30% joining us from African regions including Nigeria, Kenya and Ghana.
• 15 Community Hubs created thematic home bases for different groups
• DIP contributors created a diverse range of activations for the event
• Ecosystem teams hosted 40 events inside La Rural and 500+ side events across Buenos Aires: hackathons, workshops, meetups, hacker houses, parties, and more
