Ethereum is entering its usability era – and this November, the proof will be on display in Buenos Aires.

From November 17–22, the Ethereum Foundation’s Devconnect returns as the first-ever Ethereum World’s Fair, turning Argentina’s capital into a live showcase of what Ethereum can do in the real world today.

Ethereum in action

At La Rural, more than 75 teams will present live applications across eight themed “districts”: DeFi, Social, Privacy, AI, Gaming, Collectibles, Hardware & Wallets, and L2s.
Attendees will be able to make payments, test privacy tools, play onchain games, experiment with AI agents, and explore new identity and social protocols, all running on Ethereum.

The concept channels the world’s fairs of the past, public showcases of breakthrough technologies, but this time, the technology went onchain.

40+ events turn the venue La Rural into Ethereum City

Beyond the World’s Fair, 40+ independent events will be hosted at the main venue La Rural.

Ethereum Day on Nov 17, ETHCon (the all-Spanish developer conference), DeFi Security Summit, Bankless Summit, and more.

Explore these and more events on the Devconnect calendar.

For one week, Buenos Aires becomes a live network of builders, researchers, and users exploring Ethereum’s next decade.

Why Argentina makes sense

With inflation above 200 percent and nearly $94 billion in crypto transactions between 2022 and 2025, Argentina is one of the few countries where crypto is used daily for saving, spending, and protecting income.

Hosting the first Ethereum World’s Fair here highlights how real-world demand meets working onchain technology.

Experience Ethereum

Ethereum’s infrastructure is mature enough to support real-world applications at scale.

Devconnect’s message is clear: Ethereum works and it’s ready for everyday use.

Whether you’re a builder, researcher, or just curious to see what’s next, this is the week to be in Buenos Aires.

Experience Ethereum hands-on, meet the teams shaping its future, and see how the network is redefining the systems we use daily.
