Updates on the self-hosted hackathon “OneHack 3.0”: We recently received reports that OneHack 3.0, a self-hosted (DIY) hackathon organized by @onechainlabs , was unable to continue due to the team’s difficult financial situation. As a result, OneHack 3.0 has now been archived on DoraHacks. If you need to reach the organizers, please find the contact in their profile. Since DoraHacks is a free and open platform for both hackers and hackathon organizers, we rely on the community. We truly appreciate your help in monitoring ongoing hackathons on the platform and reporting issues promptly! To submit a report, please go to: dorahacks.io → click the ? Icon → click Report Issue icon → submit your report.

@onechainlabs ran three hackathons in one year. 543 builders total. OneHack 1.0 ($12,500 pool) - no winner announcement exists anywhere. OneHack 2.0 ($14,000 pool) - winners announced, though it's unclear if prizes were actually paid out. OneHack 3.0 ($16,100 pool) - cancelled. "Cannot pay."

A project claiming a $67 million raise says it "cannot pay" $16,000 in hackathon prizes. I participated in OneHack 3.0 by @onechainlabs on @DoraHacks. After the hackathon ended, this message appeared in the Telegram group. I started digging and nothing adds up.

Building a DeFi protocol solo is a wild ride, but seeing the vision come to life makes it all worth it. I’m thrilled to announce that OneTriangle has secured 3rd Place at the OneHack 2.0 by @onechainlabs ! 🏆 As a Solo Developer, this journey was about more than just code-it was about standing on the shoulders of giants to create something innovative. How OneTriangle Works (The Simple Formula): I merged these inspirations into a streamlined mechanism on @onechainlabs : (User Deposits Automated Yield) = Perpetual Prize Pool Your capital is safe. Only the yield powers the prizes By building with the Move language, I’ve ensured that "Zero-Loss" isn't just a slogan - it’s a programmatic guarantee. Users keep 100% of their principal while playing for the yield-generated prize. The Blueprint: Inspired by the Best OneTriangle wasn't built in a vacuum. It’s an evolution of concepts from pioneers I deeply admire: 1️⃣ The Zero-Loss Core: Inspired by @PoolTogether_ . They proved that "lotteries" can be a tool for financial health. 2️⃣ DeFi as Utility: Learning from @aave & @compoundfinance on how to turn liquidity into a value-generating engine. 3️⃣ Gamified DeFi: Inspired by @DeFiKingdoms on how to wrap complex financial mechanics into an engaging experience. The "Aha!" Moment & Community Support 🇮🇩 This project wouldn't exist without my roots at @devweb3jogja . It was at their Web3 Bootcamp batch 4 where I first dived into the rabbit hole. Huge thanks to @alexmuhammaddd (Community Lead), who first planted the seed of "Zero Loss" logic in my head while he was sharing the incredible projects built by the talented members of @devweb3jogja. Also, a massive Thanks to my mentor @yanzero_ . His deep-dive "yapping" sessions into DeFi mechanics are what fueled my curiosity to innovate in this space. Web3 adoption will be driven by apps that are both useful and fun. I’m just getting started! 🚀 To my fellow builders: Do you think "No-Loss" mechanics are the key to bringing the next billion users to DeFi? Let's discuss! 👇 #OneChain #MoveLang #solodev #DeFi #GameFi #Web3 #BuildOnChain #PoolTogether
