From June 12 to 14, ETHGlobal New York brought 486 builders to the Metropolitan Pavilion for 36 hours of hacking.

The weekend followed ETHConf, ETHGlobal’s institutional finance-focused event at the Javits Center. ETHConf brought together leaders across finance, policy, enterprise technology, and crypto infrastructure to discuss Ethereum’s role in markets, settlement, stablecoins, custody, tokenized assets, and onchain capital formation.

A few days later, the focus moved to the Metropolitan Pavilion.

Builders came from 152 cities across 44 countries. Over the weekend, they filled three floors with workshops, partner booths, mentor sessions, late-night debugging, and demos in progress. By Sunday morning, 232 projects had been submitted across 18 categories.

• 682 attendees

• 486 hackers

• 232 projects submitted

• 152 cities, 44 countries, 6 continents

• 31% new to the ecosystem

• $200,000+ in prizes

Behind those numbers: 16 partners, 105 partner reps, 18 mentors, and 20 workshops kept builders moving all weekend.

Check-in opened Friday at 1 PM. As hackers arrived, they explored the venue, visited partner booths, and started asking questions about what they could build.

Partner workshops ran throughout the afternoon, followed by dinner.

By 8 PM, everyone gathered on the first floor for Opening Ceremonies.

Hacking officially began at 9 PM. From there, builders spread across the venue to find teammates, test tools, get mentor feedback, and start shipping.

Saturday brought a few breaks between build sessions: a Loop + Line creative reset workshop, an impromptu Brazil vs. Morocco World Cup watch party, Knicks celebrations outside after the Finals win, and midnight ice cream sundaes to keep everyone going.

Submissions closed Sunday at 9 AM, followed by brunch before judging began.

Partner prize judging ran at the booths, with builders presenting directly to partners.

Upstairs on the third floor, the finalist round carried the bigger stakes: one more demo for a spot on the closing ceremony stage.

By late afternoon, 10 finalists had been selected to present, and the Closing Ceremonies began.

After 36 hours of hacking, 10 projects reached the finale and demoed on stage during closing ceremonies:

• Immunity built an onchain immune system for AI agents, with Sybil resistance, a challenge-and-bond economy, and an ENS-based reputation layer.

• LYNX created prediction-market baskets that can be bought alongside real assets.

• Canary built parametric insurance priced and settled by prediction markets.

• The Wallet Shift created a live, agent-callable ERC-8004 directory.

• Accrue replaced the AI loading spinner with paid, bot-resistant ad slots.

• Void Tactics brought a fully onchain tactical combat game into the weekend and made it tournament-ready.

• Distro built a clipping marketplace on crypto rails, paying creators per verified view.

• Cumulant created structured products on top of prediction markets.

• UNSU built a browser-native, open source wallet focused on reducing wallet friction.

• Proof of Scan built a crowdsourced scanning tool to reproduce cloaked phishing sites and generate takedown evidence.

New York also marked the debut of the Continuity Track.

For the past eight years, ETHGlobal projects had to start from zero. Existing code was disqualifying. This time, builders could bring work they had already started, as long as they shipped something new during the weekend.

Projects could enter in three ways:

• From Scratch: build a new project during the hackathon

• Extend: build on an open source repository they already maintain

• Ship a Feature: build a new open source feature on top of an existing private product

Out of 232 submitted projects, 61 chose Continuity, representing 26% of the field. Three of the 10 finalists also came through the track.

Those three finalists showed what Continuity can unlock.

Immunity used the track to keep building on its agent security work, adding Sybil resistance, a challenge-and-bond economy, and an ENS-based reputation layer.

Void Tactics brought an existing fully onchain tactical combat game into the weekend and made it tournament-ready.

UNSU continued work on a browser-native, open source wallet focused on reducing wallet friction directly inside the browser.

Continuity showed up across all major project categories. Among larger categories, AI, infrastructure, and security each had 33% Continuity participation. Gaming followed at 30%, with wallet/payments at 21% and DeFi at 18%.

Continuity belonged to no single category. Builders used it across agent security, onchain games, wallets, infrastructure, DeFi, and more. For a first run, the track gave projects with momentum a way to keep moving instead of starting over.

Across 232 submissions, DeFi and AI led the field.

Builders submitted 57 DeFi projects and 46 AI projects. Together, those categories made up 44% of the showcase. Wallets and payments followed with 29 projects, then infrastructure with 24. Security, data and analytics, gaming, privacy, social, NFTs, developer tools, and other categories rounded out the field.

A few themes stood out.

Prediction markets showed up as infrastructure. Canary used them for parametric insurance. LYNX built investable baskets around them. Cumulant created structured products on top.

Agents needed trust layers. Several projects explored ERC-8004 and the trustless agent economy, with work around discovery, reputation, verification, and coordination. The Wallet Shift’s index of agent registrations offered a clear reality check: thousands of registrations exist onchain, but far fewer are live, callable services.

Wallets got lighter. UNSU built a wallet directly in the browser. Better Wallet explored an airgapped hardware wallet. Other projects focused on onboarding, recovery, payments, identity, and fewer steps between intent and action.

Security focused on real attack surfaces. Proof of Scan tackled cloaked phishing sites by helping reproduce and document attacks. Other projects worked on safer transactions, better verification, and clearer tools for navigating risk onchain.

Together, the showcase pointed to a few clear areas of momentum: prediction markets as infrastructure, trust layers for agents, wallets with less friction, and security tools built around real attack surfaces.

ETHGlobal New York came together with support from 16 partners, 105 partner reps, 18 mentors, 20 workshops, volunteers, judges, venue staff, catering teams, and everyone working behind the scenes.

Thank you to Google Cloud, ENS, 1inch, Uniswap Foundation, Sui, World, Arc, Chainlink Labs, Ledger, Hedera, Privy, LI.FI, Canton Foundation, Dynamic, Unlink, and Blink for supporting builders throughout the weekend.

Special thanks to everyone who helped keep the venue running, the meals moving, the judging on track, and the hackers supported from check-in to closing ceremonies.

New York was the first ETHGlobal event to run the Continuity Track, and Lisbon is next.

The track will return at ETHGlobal Lisbon, giving builders another chance to bring existing work into the weekend, ship something new, and keep momentum going instead of starting from zero.

After New York, the takeaway is clear: hackathons can be part of a project’s lifecycle rather than just the place where one begins.

See you at ETHGlobal Lisbon, July 24–26.
