• The decision of judges is final for determining prizes.
• A team can have between 1 and 4 members
• You can not use another team's code.
• Breaking our Rules and Code of Conduct leads to the exclusion from the event.

Minimum Submission Requirements

• A demo is required. Show us what you built in a short video! Here’s a short guide on how to give a killer pitch. Tip: for a successful demo, address the judging criteria.
• Provide a link to the open-source code. Startups can apply with a new feature but, code must be open-source. We recommend including a Readme with information about the project.
• When submitting, don’t forget to select on DoraHacks the Tracks or Bounties you’re applying for. Make sure to explain in your application which bounties you’re applying to and the contracts you’re submitting.

Challenges and ideas

Mission

Latin America leads the blockchain revolution!

Web3 is global, but few places live and breathe decentralization like LATAM. From DeFi adoption to hacker culture, the talent is here—and Aleph '25 is the stage to prove it. This is your chance to showcase groundbreaking ideas, collaborate with the best builders, and bring your vision to life.

Build anything that excites you

This is not your typical hackathon. Aleph Hackathon is about pushing boundaries, experimenting with frontier tech, and proving why LATAM is a global crypto & innovation powerhouse.

You choose what to build. We bring the best mentors, resources, and a massive prize pool to fuel your vision.

Tracks

• DeFi — To reinvent how money works: think beyond banks, create new ways to pay, lend, borrow, and trade
• AI/vibe coding — Because the best ideas can come from anyone: no need for technical skills to experiment, create, and bring projects to life
• Privacy — One of today’s most urgent challenges: building tools that protect our data and our freedom
• Interoperability — To make every chain, app, and asset speak the same language
• Consumer apps & real-world assets — To create blockchain-powered apps that solve real-world problems and are easy to use, even for your grandma who never heard about crypto (think mass adoption)
• Public Good — To build what benefits everyone: open-source tools, shared infrastructure, and resources that no one owns but everyone can use and improve

Criteria

The projects submitted to Aleph Hackathon will be judged based on the following criteria:

Technicality: How technically impressive is the project? Does it demonstrate advanced problem-solving and engineering skills?

Originality: Is the project innovative and unique? Does it propose a new solution or a creative approach to an existing problem?

UI/UX/DX: How user-friendly and accessible is the project? Is the user interface, user experience, and developer experience well-designed and intuitive?

Practicality: How practical and feasible is the project? Does it have real-world applications, and can it be implemented effectively?

Presentation: Is the project clearly explained and well-presented? Does the team communicate their idea effectively through their pitch, demo, and supporting materials?

A successful project addresses all judging criteria. Each project will be rated on a scale of 1 to 5 across these criteria.
