This is the proof that you stopped by at the ENS booth at ETHGlobal New York. The Ethereum Name Service (ENS) is a distributed, open, and extensible naming system based on the Ethereum blockchain, and works across web3 and the whole internet. It's your identity: simple, memorable, unmistakably yours. For your hackathon project, you can leverage ENS to give names to Ethereum addresses and store user data directly on their ENS name, which acts as a interoperable profile. Or mint subnames for the users of your app. ENS is very powerful - trust your instincts as you enhance the user experience of your app. Brand new for this hackathon are L2 Primary Names. Read more about them here: https://docs.ens.domains/web/reverse/ and use them in your project. There is a dedicated prize. Find all ENS prizes here: https://ethglobal.com/events/newyork2025/prizes/ens
