Thematic Tracks

Switching tracks is allowed, but staying focused on one track and refining it through the competition, is your best shot at delivering a killer MVP.

AI

Use the Internet Computer Protocol (ICP) to build AI apps that are decentralized and transparent, like on-chain AI models or smart agents, ensuring security without middlemen. Shape AI’s future in a trustless, scalable way.

Bitcoin DeFi

Tap into ICP’s Bitcoin integration to create decentralized finance apps, enabling new ways to use Bitcoin, from lending to cross-chain deals, all with ICP’s speed and security. It’s for innovators redefining finance.

Fully On-Chain

Build apps entirely on the ICP blockchain, like social platforms or DAOs, with no off-chain needs, ensuring full decentralization and user control. This track pushes blockchain’s limits.

RWA

Use ICP to tokenize real assets like real estate or art on the blockchain, enabling shared ownership and new digital interactions. It’s about connecting the physical and digital worlds efficiently.

Open Track

For ideas outside other tracks, use ICP to explore new protocols or use cases. This track is for visionaries shaping Web3’s future with creative, cutting-edge solutions. Build Without Limits.
