HashKey Chain Horizon Hackathon runs March 10–April 23, with registration open until April 15.

The hackathon focuses on building financial infrastructure at the intersection of AI and DeFi within the HashKey Groupecosystem. Participants include developers, founders, students, and industry practitioners working in cross-disciplinary teams.

Projects are developed across four tracks: DeFi, PayFi, AI, and ZKID, with a focus on areas such as AI-driven trading strategies, onchain financial systems, and automated operations for DeFi protocols. The program is structured around a multi-week development period, with a total prize pool of 40,000 USDT.

Selected projects may receive follow-up support, including access to internal teams and ecosystem partners such as exchanges, security firms, and venture capital participants.
