Key information

  • Project submission deadline is on Sunday, April 16th 2023 at 09:00 am JST

  • Project submission is done on your Hacker Dashboard

  • You apply for partner prizes on the last step of the project submission form

  • Partner judging will take place at the partner booths inside the venue

  • Optional but encouraged: a demo video between 2 and 4 minutes that explains your project

  • The demo video will be showcased on the ETHGlobal Showcase page


🚨 Note: You should not be working on your projects before the event officially begins. This includes coding, designing assets etc. Each hack submission will be judged solely on the quality of the work completed during the duration of the hackathon. We require everyone starts building from scratch - if there is a situation where a project / team are porting or continuing existing projects then the result is that you may continue to participate but you won't be eligible for Partner prizes or being a Finalist.

🚨 Note: In order to ensure that no pre-existing work makes its way into the submission, you must also use version control for your code throughout the course of the event. Any repositories with single commits of large files without proper history will be default assumed to be unqualified unless proven otherwise

Using open-source libraries & boilerplates

  • In order to keep the event fair to all participants - we require hackers to start their projects when the event begins so that no individual or team has a head-start
  • You are however, welcome to use any open source libraries, starter-kits/boilerplates, or designing a spec of your hack
  • Your submission page will ask you to share the source code (GitHub Repo, Figma, etc.) and show that work wasn't done before the event
  • You must make a clear distinction between starting to code/design and updating pre-existing projects

Submitting your project

You have two options when submitting your project on the hacker dashboard:

1. Top finalist & partner prizes

  • If you choose this option you will need to present your project to judges at the Finalist judging session
  • Partner judging will take place at the partner booths inside the venue - the only thing you are required to do here is to select the partner prizes you are applying for in your submission form

2. Partner prizes only

  • If you choose this option you will not be attending Finalist project judging
  • Partner judging will take place at the partner booths inside the venue
  • The only requirement from you is to select the partner prizes you are applying for in the submission form

Attending a judging session

  • Information about where the Finalist project judging takes place will appear on your hacker dashboard
  • Stand in line and proceed to the judging check-in table where we will prep you for your judging room
  • Once you have passed all the judging checks you will be sent to your official judging room
  • Each team has 7 minutes in total (4 minutes for the demo and 3 minutes for Q&A with judges)

Some Questions to Expect

  • Explain the motivation behind your project
  • What types of tools did you use, and why?
  • What was your inspiration?

Judging criteria

Each project will be ranked by our judges on the following 5 categories:

Technicality - What is the complexity of problem being addressed, or their approach to solving it?

Originality - Is the project tackling a new or unsolved problem, or creating unique/creative solution to an existing problem?

Practicality - How complete/functional is the project? Is it ready to be used by their intended audience?

Usability (UI/UX/DX) - Is the project easy to use? Has the team made good effort in removing friction for the user?

WOW factor - Catch-all for other factors the previous categories may have missed

Partner judging details

  • Choose which prizes you are applying for on the last step of the submission form
  • Partners will be given a list of all the projects that are applying for their prize
  • Partners will be at their partner booth where teams line up to present live!
  • Partners will use the critera from above to decide the winners
  • ETHGlobal will announce partner prize winners during the closing ceremony

How to present

  • Go to each Partner at their partner Booth for every prize you are applying to
  • Present your hack to the Partner
  • Repeat until you have presented your hack to every partner you applied to

Tips for a good demo video

To record the video you can use tools like Loom, Zoom screen-share, or QuickTime Player on Mac

  • The minimum video length is 2 minutes
  • The maximum video length is 4 minutes
  • DO NOT speed up your video to fit the time requirement. If judges can't understand what you're presenting, they won't be able to give effective feedback.

How to present your project

  • Speak slowly and clearly
  • Do a few practice takes, pace yourself and avoid filler sounds like "uhm"
  • Avoid echo-ey sound — a good microphone can help, or try a different room with better acoustics, maybe even a closet
  • Keep introductions and project summary to be less than 20 seconds — don't spend too much time on backstory
  • Crop out any needless waiting time e.g., Metamask TX confirmations
  • If you need to fill out a form or switch between views, keep them ready in multiple tabs
  • Use slides to summarize key information
  • Don't use more than 4 bullet points per slide

Common mistakes to avoid on your demo video

We see a lot of these mistakes during submissions which requires a team to re-submit their video in order to qualify for judging. Please be mindful of these common patterns if you'd like to be considered for prizes. If we see 1 or more of these items on your submission you will be asked to re-submit the video.

  1. 🚨 DO NOT export the video in any resolution less than 720p
  2. 🚨 DO NOT exceed the 4min submission length
  3. 🚨 DO NOT speed up the video to fit under the time limit
  4. 🚨 DO NOT play music with text on the video describing your project (instead of talking)
  5. 🚨 DO NOT use mobile phones to record the video submission
  6. 🚨 DO NOT use a text to speech synthesizer
