ETHGlobal Tokyo 2026 is a three-day, in-person Ethereum hackathon scheduled for September 25 to 27, 2026 at Toranomon Hills Forum in Minato City, Tokyo, run by ETHGlobal, the team behind the flagship ETHGlobal hackathon series. It is free to attend, food included, and built around sponsor bounties spread across the Ethereum stack, so builders ship a working prototype in roughly 36 hours and pitch it to protocol teams who are actively hiring and funding.
What ETHGlobal Tokyo is and who runs it
ETHGlobal is the organization that has run the best-known Ethereum hackathons since 2019, including ETHGlobal Tokyo 2023 and recent flagships in Cannes and Bangkok. Tokyo 2026 is one stop on that in-person circuit. The format is consistent across their events: you form a small team on site, you build for a fixed sprint, and you submit a project that judges and sponsors review live.
The event sits inside ETHGlobal Tokyo Week, a broader run of community programming that, based on aggregator listings, spans roughly September 19 to 27 with conferences, summits, and side events around the city. Treat the exact side-event calendar as subject to change and confirm on the official ETHGlobal page before you book anything.
Dates and format
The core hackathon runs September 25 to 27, 2026. It is in person only, at Toranomon Hills Forum. Expect the standard ETHGlobal shape: an opening ceremony and sponsor pitches on day one, a continuous build window through the weekend, mentor office hours throughout, and final submissions plus judging near the close.
One detail worth planning for: ETHGlobal typically asks hackers to stake a small amount of crypto to hold their spot, fully refunded once you show up and submit a project. It is a no-show deterrent, not a fee. Confirm the current amount and refund terms at registration.
Tracks and prizes
As of this writing, the official prize page lists a prize pool being assembled around four confirmed sponsor bounty tracks, and it is still growing as sponsors sign on. The confirmed early tracks are:
- World ($15,000): proving humans apart from AI online and building inclusive onchain finance.
- ENS ($10,000): naming and identity, described as the universal pointer for anything on the internet.
- Uniswap Foundation ($10,000): DeFi protocol innovation, developer tooling, and governance.
- 1inch ($5,000): DeFi built around DEX aggregation and best-rate swaps.
That puts the confirmed sponsor total near $40,000 at the moment, and several third-party listings cite a $50,000 figure. Both numbers should be read as provisional. ETHGlobal prize pools almost always climb as more sponsors join in the weeks before the event, and per-track prize details on the official page currently read "coming soon." Check the live prizes page close to the date for the final pool, the full sponsor list, and the specific judging criteria per bounty.
How to actually win at ETHGlobal Tokyo
Winning an ETHGlobal bounty is less about a moonshot idea and more about shipping something real that maps cleanly to a sponsor's judging rubric. What consistently works:
Read the bounties before you pick an idea. The prizes are the spec. A project that deeply uses one sponsor's SDK the way that sponsor wants beats a flashy demo that touches five tools shallowly. With World, ENS, Uniswap, and 1inch confirmed, identity, naming, and DeFi swap flows are natural surfaces to build on.
Stack compatible bounties. One well-built app can qualify for multiple tracks at once. An app that authenticates users with World, resolves ENS names, and routes swaps through 1inch or Uniswap can submit to three bounties from a single codebase. That is how strong teams walk away with more than one prize.
Ship a working demo, not a pitch deck. Judges reward things that run. Have a deployed contract or a live frontend, a short clear README, and a two-minute walkthrough that shows the core flow end to end. Cut scope hard so the one thing you show actually works.
Talk to mentors early and often. Sponsor engineers staff the event specifically to help. Ask them what a winning submission on their bounty looks like, then build to that answer. This single habit separates finalists from the rest.
Submit early and complete the checklist. Late or incomplete submissions get filtered before judging. Lock your submission with time to spare.
Why building here positions you as a developer airdrops look at
Airdrops are never guaranteed, and no hackathon changes that. What a hackathon does change is your visible track record. Airdrop teams and grant programs increasingly weight real onchain activity and genuine contribution over farmed wallets, and an ETHGlobal Tokyo submission is exactly the kind of signal that reads as real.
Shipping here produces durable proof: a public repository, deployed contracts on a testnet or mainnet, a submission page tied to the ETHGlobal event, and direct contact with the sponsoring protocols. When World, ENS, Uniswap, or 1inch later run incentives or grants, the builders they already know from their bounties are the ones they look at first. You are not gaming an allocation, you are becoming the developer that ecosystems want in their community.
That is the honest version of positioning. You build something real for a protocol, the protocol sees your work, and if that ecosystem ever rewards contributors, you are already on the map as a contributor rather than a wallet.
Build for it with DEPLOYR
DEPLOYR helps you turn hackathon work into a real onchain developer profile that ecosystems and airdrop teams actually notice. Start shaping your build plan at /build, track upcoming events and prep strategy at /hackathons, and read the tactics behind winning submissions at /insights.
Airdrops are never guaranteed. What you can control is shipping real work, in public, for the protocols you care about. That is what DEPLOYR is built to help you do.
