It's happening: Devconnect is coming to Buenos Aires, 17–22 November 2025. And we are bringing the first-ever Ethereum World’s Fair to the city.

The Ethereum World’s Fair is for the Ethereum community and anyone curious about what Ethereum can do in the real world. We’re starting in Argentina, one of the most active crypto hubs, to show how Ethereum can bring a nation onchain with stablecoins, DeFi, decentralized identity, prediction markets, games, and more.

Main venue: We’re anchoring everything around La Rural, so the energy (and everyone) keeps flowing through the main hub.

Ethereum World’s Fair: For six days, the whole venue will transform into the Ethereum World’s Fair. We expect 15K+ attendees to explore the app showcases, events, cowork, and other spaces in the main hub.

Application showcases: Hands-on showcases of Ethereum apps, and demos to see Ethereum in action.

Core programming under one roof: Kickoff Ethereum Day (17 Nov), plus other flagship events right inside the venue (some included in your main ticket).

Cowork & Community Hubs: Desks, wifi, meeting rooms, and topic-focused spaces run by the community.

Still decentralized: City-wide community events, hacker houses, meetups, and summits continue, but the heartbeat is concentrated at La Rural.

What your Ethereum World’s Fair ticket covers:

• Kickoff day (17 Nov) and other core events – talks, workshops, and opening sessions

• Application showcases (17–22 Nov) – live demos of Ethereum apps, hands-on stations, meet the builders

• Cowork & Community Hubs (17–22 Nov) – desks, wifi, meeting rooms, and gatherings to collaborate and create
