Crypto World's Fair Hackathon Brings Together Blockchain Ecosystems

Crypto World's Fair has launched as a global hackathon for projects on all blockchains, exceeding $3.3 million in prizes. The event, organized by Colosseum, marks its first year hosting projects from various blockchain ecosystems in a single competition.

Each blockchain will have its own prize track, with Solana, Hyperliquid, Tempo, and Zcash announcing $100,000 each for their tracks. Ethereum, Base, Arbitrum, and Robinhood have announced $25,000 each. Ukrainian teams will receive special support through Superteam Ukraine, including mentoring sessions, workshops, practical resources, feedback, and coworking spaces in Kyiv.

The hackathon runs from September 14 to October 12, 2026. Before the final submission, two Demo Days will take place on October 9 (online) and October 10 (in person in Kyiv). Teams can present their finished MVPs, test their pitches, receive feedback, and compete for additional prizes.
