ETHDenver
ETHDenver
Description
ETHDenver is the largest and longest-running Ethereum hackathon and conference in the world, held annually in Denver, Colorado. The hackathon offers $100K+ in immediate prizes plus access to millions in follow-on grants and investments. The event attracts 10,000+ attendees, making it the premier gathering for Ethereum developers, founders, and investors.
Freshness (27 Aug 2026): The 2026 main event was 18–21 Feb 2026 (past). No 2027 dates on the homepage this fetch. https://www.ethdenver.com/
Unlike virtual hackathons, ETHDenver is a massive in-person event with a unique culture — the #BUIDL ethos emphasizes actually building over speculation. For ZHC builders, ETHDenver offers unmatched networking, the chance to present to top VCs and protocols, and the energy of being surrounded by thousands of developers. Many projects that started at ETHDenver have raised millions in subsequent funding.
