ETHDenver: The Largest and Longest Running #BUIDLathon in the World!

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.

To participate in the #BUIDLathon, apply for your ETHDenver ticket here before completing the #BUIDLathon application on Devfolio.

IMPORTANT: When submitting your BUIDLer application on the ETHDenver 2025 Devfolio page, use the same email you provided when registering for ETHDenver.

ETHDenver is more than a competition— it's a launchpad for success. With up to $1,000,000 in sponsor bounties and prizes and up to $10,000,000 in grants and investments, ETHDenver provides the support needed to turn visionary ideas into reality.

ETHDenver’s impact extends beyond the event. Our alumni have collectively raised over $300 million in funding (excluding undisclosed grants and early-stage investments). Past #BUIDL teams— such as 1Inch, POAP.xyz, Huma Finance, Harpie, and others— have evolved from humble beginnings at ETHDenver into key players and contributors to the blockchain ecosystem. Some have even become sponsors, partners, and integral contributors to the ETHDenver Community Innovation Festival.

Join the next wave of over 1,000 teams of #BUIDLers at ETHDenver 2025! This is your opportunity to connect with a global community that’s not just watching blockchain innovation unfold but actively driving its future.

BODEGA: We heard you! You want more fresh, hot food options, not just snacks and occasional drops—consider it done! This year, we’re massively upgrading the food and beverage experience with enhanced staffing and a wider selection of options available throughout the day and into the evening.

COFFEE/TEA CART: Our barista coffee service was a hit, so it’s back for 2025! We’re also adding new flavors and complimentary snacks to really help you get in the zone.

INTERNET: Our IT Stewards made significant infrastructure upgrades in 2024, but we're not stopping there. We’re going all out to provide the best connectivity for ETHDenver 2025:

n
• Enhanced Core Infrastructure to prevent dropped connections.
n
• Expanded NAT Pool to prevent service throttling and improve connection distribution.
n
• Increased Access Point Density in BUIDLHub to reduce equipment overload and improve coverage.
n
• Real-time Monitoring and Tactical Deployment to address wireless dead zones during the event.
n
• Hardwired Connectivity Options through network switches deployed at each row. And if you forget your Ethernet cable, we’ll also have a free “Build Your Own Ethernet Cable” Station in the MakerSpace which is moving into the BUIDLHub!

VIBE: This year’s BUIDLHub will take over the same spacious arena but we’ll be packing in way more vibe. You’ll find more diverse seating options, different levels of light in each area, more lamps and adjustable lighting, and a new festival inspired layout to replace the old rows of tables.

DJ CHILL ROOM: This year’s experience will be Legen… dary… featuring a 33 foot projection mapped dome featuring creative art from the local and international community. We’ll be bringing back the “call for DJs” with live sets taking place all week long. If you ever need a change of pace, this space will most definitely be your jam.

MAKERSPACE: This year’s MakerSpace will have an expanded support team ready to help you integrate physical tech into your software projects. As you brainstorm project ideas for this year’s BUIDLathon, consider how "phygital" connections  that bridge blockchain with the real world could take your ideas to the next level. We’ve invited several projects for you to connect with and gain firsthand insights. They’ll be demoing their innovations, showing how they’re leveraging blockchain-powered phygital tech to create real-world impact.

All attendees must adhere to the Code of Conduct to ensure a safe, inclusive, and productive environment for everyone.
