Colosseum, the platform behind some of crypto’s largest online hackathons, is going multi-chain. The company announced the Crypto World’s Fair, a cross-ecosystem hackathon offering over $800,000 in prizes and $2.5 million in venture funding, running online from September 14 to October 12.
What builders are competing for
The prize structure is layered in a way that rewards both specialization and general excellence. Dedicated tracks for ecosystems like Solana and Tempo each carry $100,000 prize pools, with Ethereum-related tracks collectively offering another $100,000. The total prize pool comes to roughly $840,000.
A $30,000 grand prize sits at the top of the heap. Below that, $300,000 will be split among 20 projects, working out to about $15,000 each. There are also separate incentives for public goods and university-focused projects.
Top-performing teams get a shot at joining Colosseum’s accelerator program, where each accepted team receives $250,000 in funding. The venture arm behind this has earmarked $2.5 million in seed and pre-seed capital specifically for projects emerging from the hackathon.
All submissions compete within a general pool regardless of which blockchain they’re built on. A Solana project goes head-to-head with an Ethereum project on the merits of the product, not the ecosystem politics.
Colosseum’s track record makes this more than vaporware
Previous Colosseum hackathons have attracted over 80,000 builders and generated more than 9,000 product submissions. The most recent major event, Solana Frontier, pulled in 2,857 submissions and led to over 74 portfolio companies receiving funding.
Hundreds of builders had already registered by the time of the announcement. Localized events are spinning up around the hackathon too, including Superteam Ukraine’s Demo Day, which features its own separate prize pool for Ukrainian builders.
