Devconnect Buenos Aires: Nathan Sexer on the First Ethereum “World’s Fair”

As Devconnect prepares to open in Buenos Aires, the global Ethereum ecosystem is gearing up for its most ambitious edition yet. This year, Devconnect invites builders, researchers, and users to experience Ethereum not as a distant future, but as a technology that is already building daily life and proving its value in real-world environments.

To understand what sets this edition apart, BeInCrypto spoke with Nathan Sexer, Devconnect Lead, about community-driven curation, the rise of stablecoin payments, Argentina’s unique place in the crypto movement, and why 2025 could be a defining year for Ethereum.

A Community That Scales Without Losing Its Core

Asked how Devconnect manages to maintain its grassroots energy while coordinating more than forty independently organized events, Sexer says the foundation of the events has remained the same since the very beginning.

“Devconnect works because it is community led. Curators shape their own events, define the depth and decide how the conversations should unfold,” he explains. “Our role is simply to remove friction, publish agendas early and create common spaces where people naturally meet.”

Those shared spaces include the Cowork, Community Hubs, Discussion Corners and even music and cinema areas designed to foster natural collaboration. The goal is to keep Devconnect accessible and open, while allowing each organizer to retain full creative ownership.

Why This Edition Feels Like Ethereum World’s Fair

This year’s Devconnect comes with a bold comparison: for the first time, organizers are framing the gathering as the “Ethereum World’s Fair.” According to Sexer, the framing reflects the moment the ecosystem is in.

“World’s Fairs historically introduced paradigm-shifting technologies. We believe Ethereum is at a similar moment,” he says. “Hundreds of applications are live today. We want people to touch and feel what a society built on Ethereum could look like.”

The intention is to showcase that Ethereum is not a promise for the future, but a powerful infrastructure layer that is already working across numerous sectors.

What Ethereum Is Ready to Show the World in 2025

While crypto discourse often revolves around what might happen in the future, Devconnect Buenos Aires is focused on what already functions at scale. And if there is one area where Ethereum is poised to stand out in 2025, Sexer says it is everyday payments.

“Payments and stablecoins will be the breakout story,” he notes. “Attendees will actually be able to use them on the ground, including paying for food directly in crypto.”

This experience will be supported by an increasingly mature Layer 2 ecosystem, production-ready rollups, practical account abstraction and mainstream UX through passkeys and session keys.

Beyond payments, visitors can expect progress in privacy proofs, open finance, on-chain treasuries, public goods frameworks for funding and identity, and new forms of on-chain media and social platforms.

Real-World Use Cases Take Centre Stage

One of Devconnect’s overarching goals is to highlight that Ethereum adoption is already happening in environments where it matters most. Argentina is one of those environments.

“Cross-border payments in high-inflation economies show how powerful stablecoins can be,” Sexer says. “Instant settlement through local offramps simply offers a better user experience than traditional payment systems.”

In addition to financial use cases, this year’s edition will feature advancements in consumer wallets designed for everyday users, as well as developments in gaming, hardware, and the fast-growing intersection of crypto and AI.

Why Buenos Aires Is the Perfect Host City

Choosing Buenos Aires was far from accidental. For Sexer, Argentina currently embodies many of the conditions that make Ethereum’s infrastructure so relevant.

“You have a crypto-native population shaped by inflation and capital controls. You have strong developer culture with universities, meetups, hackerspaces and startups. And logistically, the city is ideal for a distributed fair,” he explains.

It is a place where global innovation and local necessity converge, creating fertile ground for meaningful experimentation and adoption.

Coordinating Forty Events With One Shared Vision

Even with its decentralized structure, Devconnect operates with a clear north star.

“Every event must be builder first, high signal and curated by teams we trust,” Sexer says. “We focus on Ethereum’s top priorities, from apps and DeFi to AI, but the independence of each organizer is what gives Devconnect its identity.”

The larger narrative emerges through shared values rather than centralized programming.

The Impact Devconnect Hopes to Leave Behind

For Sexer, the legacy of this edition extends far beyond a week of talks and showcases.

“We want to bring the world to Argentina, channel talent and resources into the local community and empower local entrepreneurs, builders, students, regulators and developers,” he says.

From collaborations and job opportunities to new funding paths, the intention is for Devconnect to accelerate long-term growth for both the global and the local ecosystem.

What People Might Remember About Devconnect BA

Every Devconnec and Devcont has marked a particular moment in Ethereum’s evolution. So what will Buenos Aires represent when the community looks back years from now?

“We hope it becomes the point when people realize how big Ethereum already is,” Sexer reflects. “Not as a future promise, but as a technology making real impact today.”

In many ways, Devconnect Buenos Aires feels less like a conference and more like a moment in time. The kind of community remembers not because of announcements or headlines, but because something shifts in the collective understanding of what is possible.

As Nathan Sexer suggests, this edition is not here to speculate about the future. It is here to show a version of it that already exists. In the streets of Buenos Aires, where inflation defines daily decisions and open money is not a theory but a lifeline, Ethereum’s usefulness becomes unmistakably clear.

What emerges is a portrait of a technology that has quietly matured: stablecoins used in the same way people use cash, wallets designed for real humans, and infrastructure built not for hype but for resilience. Devconnect BA gathers these pieces into a living mosaic: not polished, not perfect, but undeniably alive.

Suppose each Devconnect has captured a different chapter of Ethereum’s evolution. In that case, Buenos Aires may be remembered as the moment the ecosystem stopped talking about potential and simply showed what it already is.

A world’s fair not of spectacle, but of substance. A reminder that the future arrives gradually, then all at once, sometimes in a city that needed it most.
