ETHChiangmai & Longevity Hackathon 2026

ETHChiangmai & Longevity Hackathon 2026 brings together builders from Web3, AI and Longevity in Chiang Mai on December 26–27. Over two days, teams of 1–4 will build real products for real people, from stablecoin payments used by local merchants to tools that help people sleep, move and live better.

Total Prize Pool: 10,000 USDT across four tracks

PayFi & RWA (3,000 USDT): bring stablecoins and onchain assets into everyday life: payments, crypto cards, merchant acceptance, remittances, real-world assets, and agentic payments. Longevity (3,000 USDT): an open, product-focused track with no Web3 requirement. Build around movement, sleep, biohacking and peptides, including AI health companions. Privacy & Data Sovereignty (3,000 USDT): give people real ownership of their data through ZK, FHE, private identity, health data sovereignty and private AI. Cosmo-Localism (Bonus, 1,000 USDT): build for real users in Southeast Asia. It can be combined with any other track.

AI is welcome in every track, and any tech stack is welcome.

Whether you’re a developer, designer, researcher or health enthusiast, come build with a global community in one of the world’s favourite cities for digital nomads.
