Colosseum has announced the winners of the Solana Frontier Hackathon, concluding the largest crypto hackathon ever with the selection of a Grand Champion, 25 additional winning projects, and several special award recipients. The online competition attracted more than 10,000 participants from over 150 countries, who submitted 2,857 final projects across a wide range of sectors, including AI, DeFi, consumer applications, payments, real world assets, infrastructure, gaming, and developer tools.
The Frontier Hackathon ran from April 6 to May 11, 2026, and marked Colosseum's fifth hackathon in partnership with the Solana ecosystem. The event surpassed every previous Solana hackathon in terms of participation, continuing a multi-year trend of accelerating developer growth. Primary sponsors included Phantom, Altitude, Arcium, World, Metaplex, Raydium, Reflect, Coinbase, and the Solana Foundation, all of which provided resources and support for participating founders.
According to Colosseum, the quality of submissions increased significantly alongside the record number of entries. As a result, organizers expanded the number of winning teams by selecting 5 additional projects to receive awards.
CrowdBrain Claims Grand Champion Title
The Frontier Hackathon's highest honor went to CrowdBrain, a vertically integrated robotics DePIN platform designed to train users in simulation, qualify operators through quality assurance, and connect the best performers with real world robotics work such as teleoperation, data collection, and failure recovery.
As Grand Champion, CrowdBrain received a $30,000 prize paid in Phantom’s $CASH stablecoin.
Top 25 Projects Showcase Broad Industry Innovation
Beyond the Grand Champion, Colosseum recognized 25 additional projects that demonstrated strong execution, founder market fit, technical ability, and long-term startup potential.
The winning projects covered an exceptionally broad range of industries. Consumer investing platform Peaks lets users build AI-driven portfolios around ideas, sectors, or personalities, while Alpha Group Trading offers a social mobile trading experience.
In prediction markets, Bench aggregates insights and rewards useful signals, and Mentioned enables speculation on word usage across media.

Other winners included WeLikeSports, JK Index, Fraudsworth, One Arena, Stablecorp, The Syndicate, Nomu, Crafts, Memetic Machines, and Traded.gg.
University and Public Goods Awards
Colosseum also presented two special awards recognizing outstanding contributions beyond the primary competition. The University Award, which honors the strongest project led by university students, went to IOChain, earning a $10,000 prize.
Meanwhile, the Public Good Award recognized Zoneless for developing an open source project that benefits developers throughout the Solana ecosystem. Zoneless also received a $10,000 prize. In addition, Colosseum recognized 16 projects with honorable mentions.
Competition Reaches New Level
Following the announcement, Colosseum Cofounder Matty Taylor revealed that Colosseum plans to double the size of its next accelerator cohort, reflecting the unusually deep pool of high quality startups emerging from Frontier.
Michael Rinko, Associate at Colosseum, emphasized that selecting the winners proved considerably more difficult than in previous years. According to Rinko, weeks of interviews, due diligence, and internal debate were required before narrowing the field from 2,857 submissions to just 26 winners, making Frontier the organization's most competitive hackathon to date.
Community organization Superteam also celebrated the results, noting that projects from its network captured 16 of the 25 top prizes, highlighting the growing influence of regional builder communities across the Solana ecosystem.
What Comes Next
While the awards recognize the strongest projects from Frontier, the competition also serves as a gateway to Colosseum's startup accelerator. Organizers confirmed that they will announce which winning teams have been selected for the next accelerator cohort in a future post.
Selected founders will receive pre-seed funding, mentorship, and access to Colosseum's network of investors and ecosystem partners as they continue developing their products.
With more than 10,000 participants, 2,857 submissions, and one of the most competitive judging processes Colosseum has conducted, Frontier has established a new benchmark for crypto hackathons while providing a launchpad for the next generation of Solana startups.
