The ETHGlobal New York Pragma and Hacker Café

Since the beginning of this year, Thursday marks the community coming together and warming up for the upcoming hackathon with our two events ETHGlobal Pragma and our Hacker Café.

Our fifth edition of Pragma was dedicated to the Future of DeFi and Scaling. With New York being home to the largest stock exchange and other traditional institutions, we couldn’t think of a better playground to reimagine the future together. We invited founders and leaders to a handpicked series of high-quality talks that stimulated thinking and discussion among a curated community.
Together with some of the most insightful speakers including Joseph Lubin, Kain Warwick and Camila Russo we took an afternoon-long excursion into what the future might behold.

Chelsea Square, which dates back to 1817, was established to house the General Theological Seminary and has served as the setting for some of New York’s most unique and unforgettable events. The lovely brick and stone buildings in Chelsea are surrounded by lush private gardens, creating a beautiful sanctuary in the heart of the city.

The grand Hoffman Hall at Chelsea Square opened its door for curious web3 builders and thinkers.

We would like to thank our remarkable set of speakers as well as our attendees for joining us for an afternoon of reimagining the future.

We are already gearing up for ETHGlobal Pragma Istanbul! In town for our hackathon or Devconnect? Make sure to secure your ticket now:

On the morning of that same Thursday, only a few minutes away from Pragma, the Hacker Café at Worthwild in Chelsea became the buzzing hub for hackers to enjoy networking and team building, while also being treated to delicious charcuterie, pastries and artisan coffee. By noon the Café was more than full, with plenty of ideas flooding the space and dozens of new connections made!
Overheard: The lunch seemed to have been a hackers’ favorite just as our special Mocktails zkSpritz and TeaVL! 💙

The ETHGlobal New York Hackathon: Kickoff and The First Day!

Located within New York’s iconic Chelsea Piers, Pier Sixty amazed with its timeless marble and wood themed interior and its alluring waterfront — offering some of the views on the iconic cityscape in 🏙 Manhattan.
As the doors finally opened, hackers rushed to our registration desks and collected their swag bags, excited for an action-packed three days! After just a few hours, thousands of community members had already checked in, and the bustling networking with partners and dearly missed web3 friends had begun.

Day 1: Friday, September 22nd

On Friday afternoon, attendees could choose from 32 different workshops The valuable tutorials and hands-on workshop helped set up hackers for success for the rest of the weekend: From “Introduction to Uniswap V4” by Tyllen to the Base Workshop with Carl Fluke and ENS’ Identity in your Apps by Greg Skril, our partners covered all the necessary steps to make it easy for our hackers to integrate their tech stack.

In the span of five hours and across three different workshop rooms hackers could learn in an intimate atmosphere from ecosystem champions.

Our partner workshops are a chance to learn from the best web3 educators IRL!

The Team Formation & Idea Brainstorming Session that took place in the evening is designed to provide hackers a hands-on experience, promote interactive learning, and encourage them to think creatively about the potential applications of their work. This time, we were excited to be joined again by Austin Griffith, one of the most popular educators in the space.

In between, the crowd was of course paying the plenty of partner booths a visit — getting your questions answered, some hackers pitching already formed ideas — and of course, grabbing some unique swag items to add to their collection.

For our own swag, we tried to pair local delicacies such as Sugarfina’s infamous pineapple gummy bears with motifs of the unmatched coolness of New York Street Style (thank you to Franky Nines for designing the sticker sheet!). We always want to create swag that’s helpful for our ever-traveling and tech-affine hackers: A laptop stand (don’t forget to pair with our Posture Corrector from ETHGlobal Waterloo, for ideal results) and a backpack by the brand BÉIS by Shay Mitchell.

Opening Ceremony with Kartik Talwar

Hackers were busy plotting and planning ahead of the 36-hour hacking marathon that was about to begin.
But, first, everyone got together to mark the occasion by attending our Opening Ceremony, a well-known tradition at ETHGlobal events at this point. Our very own Kartik Talwar went over all the events’ Dos and Don’ts, crucial due dates, and venue layout in great detail in front of a full house.

Our partners were presenting their partner prizes in unique ways and made haggling for hackers attention a lot of fun!

Day 2: Saturday, September 23rd 2023

Saturday has arrived, heralding the start of the first and only full day of hacking. Day 2 is all about open collaboration; hackers gathered in the hacking spaces as soon as the sun rose, ready to tackle the mountain of work that awaited them. The halls of Pier Sixty quickly filled up as the weather shifted: some of our hackers encountered rainy New York weather for the first time! ☔️

Later in the day, our hackers had the choice of participating in the Project Feedback Session, which gave them a fantastic opportunity to acquire a fresh perspective on their ideas and receive critical feedback from seasoned tech mentors. Our mentors were on hand to assist hackers in improving their builds and getting new ideas, whether they were encountering problems with their code or wanted a second opinion. Our mentors were easy to spot, wearing bright yellow vests 🦺, sitting at the mentor table and prowling the arena outside of the session looking for hackers who needed assistance at the tables.

Day 3: Sunday, September 24th 2023

The final day always comes sooner than you think. A critical and intense time for our hackers, but also one filled with the most joyous moments!

🧨 Countdown to Submission & Judging
The night before the submission deadline, our team of hackers spent polishing their projects and adding finishing touches.
As the final seconds ticked away on Sunday morning, our volunteers encouraged them with cheers and sighs of relief could be heard in the entire venue:

Anticipation quickly returned as the hackers presented their work to the judges. It’s time to show off what the last 36 hours were dedicated to: All 303 projects who came out of ETHGlobal New York are a big win for the ecosystem’s development, as they expand its horizons and onboard new opportunities and talent!

An intense morning at our judging booths!

🏆 The ETHGlobal New York Closing Ceremony

For the most of the morning and lunchtime, our hackers were busy presenting their projects in the Partner Judging and, for those who opted for it, the Main Judging sessions. The latter require hackers to meet our highly skilled and experienced judges, and pitch to them life. All hackers were notified around 2:30pm that the 13 finalists of the ETHGlobal New York hackathon had been picked. Hackers couldn’t wait to hear the announcement they’d been anticipating all weekend: all partner prize winners and finalists demos were going to be unveiled during the Closing Ceremony.

Those who couldn’t be at Pier Sixty in-person could choose to be with us via livestream on The Closing Ceremony served as a testament that ETHGlobal New York had been another impactful event, promoting the talent of existing community members and onboarding a lot of new talented builders. We’re over the moon to have received 303 projects that are promising seeds laid within Ethereum. Seeds that can help us grow this ecosystem beyond our imagination.
