An online hackathon bringing together builders and founders across blockchain ecosystems to launch breakout startups.

Colosseum, whose startup competitions were previously focused on Solana, is launching the Crypto World’s Fair hackathon for projects across various blockchain ecosystems.

Now, Solana teams will compete not only against each other, but also against products built on Ethereum, Base, Sui, Zcash, Bitcoin, Tempo, and other ecosystems. The goal is to bring top founders and developers together in one arena, allowing the best products to compete regardless of their chosen technology stack.

Solana and Tempo have already announced $100,000 prize pools for their respective tracks, while Base has committed $25,000. Details regarding Ethereum, Robinhood, Sui, Zcash, Bitcoin, and others will be announced shortly.

In addition to the global Crypto World’s Fair awards, Ukrainian participants will receive extra opportunities from Superteam Ukraine:

- Separate local track awards: Up to $10,000

- Additional Demo Day prize pool: Up to $5,000

- Best Startup Ideathon idea: $500

- Post-hackathon project development grant: Up to $10,000
