In the city that never sleeps, ETHMumbai found its rhythm
Last month, Mumbai hosted its Ethereum hackathon: ETHMumbai 2026.
Here’s a quick tour, no bus required :P
Built in motion
Over the years, we have been hosting ETHIndia, bringing builders from across the country together. Now, we’re seeing more teams, more cities, and more communities step up and carry this forward.
We were super excited to see ETHMumbai kick off in 2024 and push things even further this year. What once felt centralised is now expanding into a decentralised set of nodes, with new hubs taking shape and building their own momentum.
With Devcon set to arrive in India, this year already feels like an inflection point. In many ways, it’s a moment that’s been a long time coming,
Chapter 0: Mumbai in Progress (MIPs)
Every great event has a pre-story. ETHMumbai’s was the MIPs.
Mumbai In Progress meetups happened before the main event: small, community-led sessions where builders across the city came together to talk, build, and figure out what ETHMumbai could be.
Chapter १: The Start
The conference kicked off with a Dhol Tasha performance, a traditional drum ensemble that got the energy going from the first beat.
From there, the day unfolded across multiple formats: Double Deck for keynotes and core talks, Single Deck for workshops, and Open Deck, where parallel sessions ran through headphones.
A key moment was the Devcon announcement, where the team introduced the Road to Devcon and broader ecosystem programs, connecting India to the global Ethereum community.
The ETHMumbai App tied everything together, making it easy to navigate sessions and stay in sync throughout the day.
Chapter २: The Build
The next day, we moved to the World Trade Centre for the hackathon.
With 200+ hackers on the floor, the energy was instant, teams forming, ideas moving fast, and the buildathon kicking off.
Mentors and organisers kept the energy tight, workshops ran in parallel, giving builders the depth they needed to sharpen their approach. Over the next 36 hours, teams built across tracks from sponsors including Base, ENS, HeyElsa, Fileverse & BitGo.
Interval
The team also organised a guided bus tour across the city as a short break during the hackathon.
Scheduled in the evening, it wound through South Mumbai, past CST, the Gateway of India, and the Taj. For a couple of hours, the laptops stayed shut, and the city took over.
Cameo: Kaali-Peeli, Camera & Action
In between all of this, we managed to pull off something we're pretty proud of. In collaboration with Devcon and ETHIndia, we sat down with some prominent web3 figures for a series of interviews, filmed inside Mumbai's iconic kaali-peeli taxi.
The conversations captured builders’ stories, their journeys, and how they found their way into the Ethereum ecosystem.
It was a fun format, and honestly, a fitting one for the city.
Chapter ३:The Final Stretch
As the hackathon entered its final stretch, the focus shifted to refining ideas, debugging relentlessly, and pushing projects toward submission.
The result ...
With over 80 projects built and a prize pool exceeding $10K, the stakes were clear, and the energy stayed high until the very end.
The hackathon brought together a strong lineup of judges and mentors to evaluate and engage with the work on display, including Denver Dsouza from Devfolio, who was there helping guide and evaluate the projects being presented.
Here are the builds that turned heads:
Beyond the hackathon …
All around, ETHMumbai was an experience of its own, from how the events were designed to the builder mindset, everything carried a distinct pinch of Mumbai.
And when hackers left the venue, they didn’t just leave with experience; they carried a small piece of the city with them.
With Devcon set to be hosted in Mumbai later this year, we’re excited to see the city bring that energy back on an even bigger stage.
A big thank you to all the volunteers, hackers, and partners who made this experience what it was. We can’t wait to share what we have in store for November.
Till then, Never Stop Building 🛠️
