ETHGlobal Mumbai 2026 is a 36-hour in-person Ethereum hackathon run by ETHGlobal, scheduled for November 6 to 8, 2026 in Mumbai, India. It brings the ETHGlobal circuit to one of the fastest-growing builder scenes on earth, with sponsor bounties spread across the Ethereum stack and a finalist demo round in front of protocol teams who are actively hunting for real developers.
If you build here, you are not just chasing a prize. You are putting verifiable, timestamped work in front of the exact ecosystems whose future airdrops reward early contributors. That is the whole game, and it is the reason this event is worth your weekend.
What ETHGlobal Mumbai 2026 Is and Who Runs It
ETHGlobal is the organization behind the largest recurring Ethereum hackathon series in the world, running both in-person events and online rounds like ETHOnline and HackMoney. Their 2026 in-person calendar lists Lisbon (July), Tokyo (September), and Mumbai (November) as the flagship IRL stops.
Mumbai is ETHGlobal's return to India, following earlier India events including ETHGlobal New Delhi. India already produces a huge share of ETHGlobal participants globally, and Mumbai anchors that energy in the country's financial capital. Note that ETHGlobal Mumbai is a separate event from ETHMumbai, a community conference and hackathon held earlier in the year in March 2026 by a different organizer. If you are targeting the ETHGlobal event, the dates that matter are November 6 to 8.
Dates and Format
The confirmed dates on ETHGlobal's official events page are Friday November 6 through Sunday November 8, 2026. The build window is the standard ETHGlobal format: roughly 36 hours of hacking bookended by opening ceremonies, workshops, sponsor office hours, judging, and a closing demo round.
The rule that trips up newcomers: your project must be built during the event. Work created before the hackathon does not qualify and is excluded from judging. You can plan, read docs, and sketch architecture in advance, but the commits that count happen on the clock. Attendance is by application, so apply early rather than assuming a walk-in spot.
Tracks and Prizes
ETHGlobal events are structured around sponsor bounties rather than a single monolithic prize. Each sponsor sets its own challenge, its own judging criteria, and its own payout, and the prizes are not exclusive. You can submit one project to multiple bounties at once, plus any open finalist track.
As of now, the full sponsor list and total prize pool for ETHGlobal Mumbai 2026 have not been publicly published, so treat any specific dollar figure you see elsewhere as unconfirmed. For reference, recent ETHGlobal events have carried prize pools well into six figures across dozens of sponsors, and finalist teams at recent events received perks such as 1000 USDC to verified wallets plus a finalist pack. Expect bounties spanning the Ethereum stack: L2s and rollups, account abstraction and wallets, DeFi protocols, oracles, privacy and zero-knowledge tooling, developer infrastructure, and increasingly onchain AI and agents.

How to Actually Win
Winning at ETHGlobal is less about a genius idea and more about scoped execution and a clean demo. Here is what consistently separates finalists from the pile.
Pick two or three sponsor bounties and design for them
Read the bounty descriptions before you write a line of code. The teams with the best return build one focused project that legitimately satisfies two or three specific sponsor prizes rather than a sprawling app that satisfies none. Deep, correct integration of a sponsor SDK beats a shallow logo drop every time, because sponsors judge integration depth and real usage.
Ship something that runs
Judges see hundreds of slide decks. A deployed contract on a testnet, a working frontend, and a live transaction in the demo will out-score a more ambitious idea that only exists in Figma. Keep the scope brutally small so the core loop actually works by Sunday.
Use sponsor office hours
Sponsors staff booths and office hours specifically to help you integrate their tech. The teams that talk to sponsor engineers on day one hit fewer walls and, bluntly, get remembered by the people scoring them.
Nail the two-minute demo
Lead with the problem, show the working product, then explain the integration. Practice it. A crisp demo that shows real functionality is the single highest-leverage thing you do all weekend.
Why Building Here Puts Airdrops on Your Radar
Here is the honest mechanism. Airdrops are never a payment for showing up, and no one can promise you one. What they often do reward is verifiable early contribution to an ecosystem, and a hackathon is one of the cleanest ways to generate exactly that signal.
When you ship a project at ETHGlobal Mumbai that integrates a sponsor's protocol, several things become true at once. Your work is timestamped and public. Your GitHub shows you deploying real contracts and using real SDKs. Sponsor engineers have your name attached to a working build. If that protocol later designs a distribution to reward developers and power users, the people who already used the stack meaningfully are the natural audience.
This is the difference between farming and building. Farmers click. Builders leave a portable, provable track record that follows them into every future opportunity in that ecosystem. ETHGlobal Mumbai is a chance to build that record in front of a room full of the teams that matter, in one of the most active developer markets in web3.
Turn Your Hackathon Work Into a Track Record
A weekend of code only compounds if people can find it. DEPLOYR helps you package the projects you ship at events like ETHGlobal Mumbai into a storefront that proves you are a real onchain developer, the kind future ecosystems actually look at. Explore /build to set up your developer portfolio, browse more events on /hackathons, and read /insights for how builders position their work.
Airdrops are never guaranteed. What you can control is the quality and visibility of what you ship, and that is the only edge worth building.
