Monad Blitz lands at Les Lokaal in Amsterdam on Saturday, August 29, 2026 - a one-day, $3,000 hackathon running from a 9:00 AM breakfast to 7:30 PM prizes, pitched as the longest-running vibe-coding event in web3.
Ship something in a single day
Hackathons increasingly sprawl across entire weekends, so Monad Blitz's bet is refreshingly compressed: one day, one chain, a working prototype by dinner. On Saturday, August 29, 2026, the series arrives at Les Lokaal on Oderweg in Amsterdam, presented by Encode Club and hosted with the Monad Foundation, AI Builders and CryptoCanal.
The organizers make a claim few can match: since launching in May 2025, Blitz has run more than fifty editions from Shanghai to San Francisco, Lagos to Lisbon, calling itself the longest-running vibe-coding hackathon in web3. Thousands of participants and hundreds of prototypes shipped, by their count.
The single-day constraint is a feature, not a compromise. Weekend-long hacks breed ambition that collapses by Sunday; a seven-hour build window forces scope discipline that professional engineers will recognize from shipping real products.
Nine to seven-thirty, mapped out
The schedule is published to the minute. Doors and breakfast open at 9:00 AM, welcome and introduction at 10:00, then a Monad 101 workshop at 10:15 to bring everyone up to speed before hacking begins at 11:15. Lunch lands at 1:00 PM, code freeze at 5:00, submissions due at 5:30, pitches from 6:00, and prizes plus closing remarks from 7:30.
That morning workshop matters more than it looks. Monad is a high-performance EVM-compatible Layer 1 claiming throughput up to 10,000 transactions per second, and Blitz explicitly welcomes Web2 developers making a first crypto attempt alongside seasoned onchain builders.
Solo builders and formed teams are both fine, and mentoring runs through the morning to unstick early problems. If you have been circling Monad deployment without committing, this is a structured excuse to finally push code to it.
Three thousand dollars and a demo crowd
$3,000 USD in prizes is modest by hackathon-industry standards, and the organizers seem aware the money is not the hook. What they sell instead is access: a direct line into the Monad ecosystem, with founders, builders and investors in the same room rather than behind a booth.
Pitching to a live crowd at 6:00 PM after seven hours of building is its own filter. The projects that win tend to be the ones scoped honestly - a clean MVP demonstrated convincingly beats an ambitious repo that cannot survive a demo.
Capacity is limited and registration requires host approval, so apply early rather than assuming Amsterdam's size guarantees you a seat. Bring a charger, a team or a good solo pitch, and expect to be tired in the satisfying way.
Amsterdam as host city
The venue choice slots neatly into Amsterdam's dense crypto calendar. Co-host CryptoCanal runs monthly crypto drinks in Amsterdam and Rotterdam and powers Common S3nse, the privacy-focused conference and hackathon returning to the city September 4-5 - meaning visiting builders can chain the two weekends into a proper Netherlands residency.
Encode Club brings its own gravity as a London-headquartered community claiming 500,000 professionals across AI and web3 events, hackathons and accelerator programs, while AI Builders adds a global network of 8,000-plus engineers self-organizing over a hundred meetups yearly.
Standard housekeeping from the Monad Foundation applies: attending means consenting to photography and recording. Beyond that, show up at 9:00 sharp for breakfast, treat the 10:15 workshop seriously even if you think you know EVMs, and remember that in a seven-hour hackathon the person who starts scoping at 9:05 usually beats the genius who starts at noon.
