This POAP certifies that the holder participated as a hacker in the Aleph Hackathon, held during the Pop-Up City in March '26. Aleph Hackathon aimed to bring together builders from across Latin America and around the world to tackle real-world challenges using crypto and emerging technologies. Emerging technologies were shaping the next wave of real-world systems, from how financial infrastructure was built to how science was accelerated, complex workflows were automated, and autonomous systems were designed.

This POAP confirms that you were a Hacker at ETHGlobal Buenos Aires 2025 which took place as part of Devconnect ARG and marked ETHGlobal’s long awaited return to Argentina! 🇦🇷 This event saw a remarkably experienced set of 1,195 hackers and 1,766 overall attendees build 475 projects in just one short weekend. Thank you so much for joining and being a part of what makes each event so special.

Agents, builders, caffeine — the perfect mix. At ETHGlobal Buenos Aires 2025, hundreds of developers explored the next wave of verifiable, intelligent systems with Nethermind in the mix. You built, tested, broke things, and maybe even fixed them. This POAP is proof you were part of the Agentic moment that started it all.

This POAP was given to those attending Devconnect 2025. POW! is a Fully onchain clicker game on Starknet with a UX as smooth as web2.

This POAP was given to visitors of the Nym Booth held at the Ethereum Worlds Fair, Devconnect, Argentina, 2025 for downloading and getting a free trial of NymVPN. NymVPN is the user facing gateway to the Nym Noise Generating Network, offering both dVPN and Mixnet modes for fast dVPN and anonymous Mixnet usecases.

Connect with other builders, talk to teams looking for talent, meet your users, or showcase your app at the Ethereum World’s Fair. Explore what Ethereum is for and what it enables, test applications, and win in some fun challenges.

Aleph Hackathon aims to unite builders across Latin America to tackle real-world challenges. It’s designed to be more than a hackathon — it’s a space to learn, build, and grow with mentorship and community support before, during, and after the event.
