ETHDenver
Feb 17–21, 2026Denver, USA
ETHDenver is the world's largest Ethereum innovation festival and the longest-running Web3 BUIDLathon — a hybrid hackathon, conference, and community gathering that transforms Denver into 'New BUIDL City' for a full week. Builder-first in philosophy, it prioritises hands-on development over keynote hype, with tracks spanning infrastructure, security, DeFi, and the future of decentralised governance. Attendance is free to apply for, keeping the community ethos intact. Dozens of top Web3 startups — now household names — trace their founding moments to a Denver hackathon table.
