Devcon newsletter

On Ethereum today, you can pay, play, vote, save, borrow, lend, and chat. At Devconnect in Buenos Aires (17-22 November 2025), you’ll experience that shift hands-on, IRL, at the first-ever Ethereum World's Fair.

Devconnect Argentina wrapped up as the largest Ethereum Foundation event yet with 14k+ attendees. Read the recap with stats and highlights of the first-ever Ethereum World's Fair.

What if Ethereum had a World’s Fair? We’re doing it in Buenos Aires, Nov 17–22.

Devconnect 2025 will be held in Buenos Aires, Argentina, from November 17th to the 22nd, 2025! This year, we are aiming for something bigger than just Devconnect: We want to support an effort that the local community has already started — bringing Argentina onchain.

World’s Fairs showcased the biggest innovations of their time. In this spirit, Ethereum gets its own World’s Fair this November in Buenos Aires at Devconnect! Top teams in Ethereum will show what they're building. And you can experience what Ethereum can do today.

Devconnect is coming to Buenos Aires this November, and we're supporting local builders, organizers, and communities on the mission to bring Argentina onchain.
