1/ Crypto World's Fair has commenced! 🎡 🌍Our online hackathon is open to builders & founders across blockchain ecosystems 💰Over $800k in total prizes and $2.5 million from Colosseum's venture fund 🏁Product submissions due by October 12, 2026 Join:

2/ Colosseum hackathons are not structured like traditional hackathons. They're intensive engineering and business sprints where builders and startup founders vie for prizes, accelerator acceptance, and seed funding. Learn more about Colosseum:

3/ Crypto World's Fair is our first competition open to all builders across crypto ecosystems, and we will be awarding $330k total to the best 21 startup submissions across chains. In addition, there are dedicated hackathon prize tracks (pavilions) for the following blockchains: - $100k for @solana - $100k for @Tempo - $100k for @Zcash - $100k for @HyperliquidX (HyperCore + HyperEVM) - $100k for @Ethereum ecosystem (Ethereum L1 + @base + Robinhood Chain + @Arbitrum One) We will also reward the best student team and public goods project with $5,000 each.

4/ While Crypto World's Fair is online, we're inviting a select group of founders to build IRL at Colosseum's SF office during the competition. Approved devs get a desk/monitor + an interview for our next accelerator batch. SF Builder Station | Apply:

5/ Lastly, thank you to all of the foundations and organizations who contributed to the prize pools. And thank you to our recurring contributors @phantom, @altitude, @Raydium, @reflectmoney, and @superteam. Good luck to the thousands of builders already competing in the arena!
