What is ETHDenver?
ETHDenver is the largest and longest-running Ethereum community event in the world. Founded in 2018, it has grown from a small hackathon with a few hundred attendees to a week-long mega-event that draws over 20,000 participants from around the globe. It combines a massive multi-day hackathon (the #BUIDLathon), a world-class conference, hundreds of workshops, and countless community side events.
Held annually at the National Western Complex in Denver, Colorado, ETHDenver is organized by SporkDAO -- a decentralized autonomous organization that embodies the community-first ethos of the Ethereum ecosystem. The event is known for its inclusive culture, with free access for BUIDLers (hackathon participants) and an open application process for the conference.
Over the years, ETHDenver has served as a launchpad for some of the most important projects in the Ethereum ecosystem. Many successful protocols, tools, and companies have their origins in #BUIDLathon projects. The event has become a barometer for the health and direction of the Ethereum developer community.

ETHDenver 2026 at a Glance
ETHDenver 2026 was the biggest edition yet, with over 20,000 attendees and 5,000+ hackathon participants across seven days of events.
The event theme centered on "Building the Onchain Future," reflecting the growing maturity of the Ethereum ecosystem post-Pectra upgrade.
Major themes included L2 interoperability, account abstraction in production, the AI-blockchain convergence, and the regulatory clarity brought by the GENIUS Act.
Over $3 million in bounties were distributed across five hackathon tracks, including a new AI x Blockchain track that attracted record participation.
The Ethereum Foundation shared roadmap updates including plans for Verkle trees, statelessness, and further blob scaling in the next protocol upgrade.
International attendance increased by 40% year-over-year, highlighting ETHDenver's growing global significance in the crypto conference circuit.

ETH Price Action Around ETHDenver
ETHDenver has historically coincided with periods of heightened market attention for Ethereum. The concentration of announcements, developer enthusiasm, and media coverage can influence short-term sentiment, though long-term price movements are driven by broader market forces.
In 2026, Ethereum entered the event period amid a constructive macro environment, with the ETH spot ETF gathering steady inflows and the post-Pectra ecosystem showing strong on-chain metrics. Network activity, gas revenue, and L2 TVL all showed positive trends leading up to and during the event.
