Colosseum, known for organizing startup competitions, just announced the launch of the Crypto World’s Fair—a multichain hackathon for teams building across different blockchains. The total prize pool and potential investments for the top startups will top $3.3 million.

Colosseum Expands Beyond Solana

Up until now, Colosseum’s events have mostly focused on the Solana ecosystem. This time, projects on Solana, Ethereum, and other chains are all invited to join, opening up the field to a wider range of teams and tech stacks.

What the Multichain Format Brings

By going multichain, the hackathon lets more teams participate and show off use cases on the networks where they’re already building. It’s a shot for devs to compete for serious prizes and early-stage investment—right where their projects live.

Why This Move Matters

Colosseum’s pivot to a multichain approach lines up with what the market wants: more teams are launching ideas across multiple networks from the jump. This new hackathon could draw even more developers into different ecosystems and speed up the rollout of cross-chain products.
