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 visitors of the Burner booth held at the Ethereum Worlds Fair. A Burner card wallet is the easiest way to get started on Ethereum. Simply tap Burner to your phone and load funds, swap tokens and save NFTs. Burner uses the same kind of secure element found in expensive hardware wallets but without the hassle of tiny screens or a confusing set up.

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.

The standard for secure onchain applications at any scale. Build, secure, and operate across 30+ chains with OpenZeppelin Contracts and open source tools. Lock down your code with our gold-standard smart contract and blockchain infrastructure audits.

This POAP confirms that you were a Hacker at ETHGlobal Cannes 2025, ETHGlobal’s first hackathon in Cannes! 🇫🇷🌴 This event saw a remarkably experienced set of 835 hackers and 1150 overall attendees build 334 projects in just one short weekend. Thank you so much for joining and being a part of what makes each event so special.
