ETHDenver is the world’s largest and longest running blockchain-powered #BUIDLathon (fka hackathon). Every year, more than 25,000+ innovators from over 125 countries converge to create a week-long festival of innovation.

ETHDenver is a world renowned gathering place where developers, creators, and visionaries come together to address critical challenges and bring groundbreaking ideas to life in the fields of blockchain and distributed computing.

Captain Ethereum & The Rise of New BUIDL City

The Etherverse is vast, but at its core lies New #BUIDL City - a digital metropolis where innovators, builders, and dreamers unite to forge the next era of open finance, governance, and connectivity.

ETHDenver returns in 2026 with new everything — a new venue, new tracks, and an entirely fresh experience for all the builders out there.

To ensure everything goes smoothly, please enter your ETHDenver ENS subdomain (for example: buffy.ethdenver.com) in the application form.

• If you haven’t created your ETHDenver Account—and your ENS subdomain—yet, just visit app.ethdenver.com to set it up.

• You’ll need this account (and ENS address) to get your ETHDenver ticket as well.

This year, we’re also keeping the onsite BUIDLing duration more concise — four days instead of the longer format of previous BUIDLathons. The BUIDLHub will be open from Wednesday, Feb 18th through Saturday, February 21st. You’ll still have the opportunity to start your project virtually a week prior when bounties are announced on Wednesday, February 11th.

Join the SporkDAO Discord to continue the conversation with all the other BUIDLers attending ETHDenver 2026!

Checkout the ETHDenver 2026 Tracks:

Track 1 — ETHERSPACE: The User-Owned Internet

The internet is being rebuilt — one where users own their identity, data, and creations. This track explores the decentralized web built on Ethereum: from wallet-based identity and creator economies to social platforms, NFT innovation, and legal frameworks for ownership. It’s about reclaiming the internet, one block at a time.

Track 2 — Devtopia: The Infrastructure Frontier

The builders’ realm. Devtopia is where Ethereum’s core infrastructure evolves — scaling solutions, L2s, developer tooling, security frameworks, and breakthrough research in zk and modular systems. This track is for those pushing the technical boundaries of what’s possible under the hood of Ethereum.

Track 3 — New France Village: The Future of Finance

DeFi sparked a revolution — now it’s time for the next phase. This track bridges decentralized and traditional finance, exploring real-world assets, stablecoins, policy, and compliance innovations. Whether it’s institutional adoption or new models for financial inclusion, this is where Ethereum meets Wall Street — and Main Street.

Track 4 — Futurllama: Frontier Tech & Wild Ideas

Where imagination meets engineering. Futurllama is for the builders experimenting with what’s next — AI, DePIN, new primitives, and the unexpected intersections between emerging tech and Ethereum. If your idea sounds a little crazy but could change everything, this is your home.

Track 5 — Prosperia: Cypherpunks, Solarpunks & Communities

Prosperia celebrates the human side of Ethereum — the people, movements, and values that sustain it. From privacy and governance to regenerative finance, DAOs, and public goods, this track explores how decentralized technologies empower collective action and reimagine prosperity for all.
