Frequently asked questions


What is ETHWaterloo?

ETHWaterloo is the world's largest Ethereum hackathon, where over 300 developers of all backgrounds will work on projects using Ethereum that can have an impact on the world. We enable teams to make something great in only 36 hours by providing an abundance of hacking resources like mentors, sponsors, and software. Sleeping is optional, but trying to make awesome things is not.

Who can participate?

Anyone from anywhere in the world can apply. Applications are based on interest in Ethereum and proven ability to write software.

How much does it cost to attend ETHWaterloo?

Admission to ETHWaterloo is completely free.

How do I get to ETHWaterloo?

We will be providing several buses from Pearson airport (YYZ) in Toronto. Otherwise, travel is up to you to figure out. We recommended booking flights and buses well in advance to minimize the cost to get here. Depending on sponsorship efforts, we may be in a position to reimburse some of your expenses.

How many people can be on a team?

You can form teams of up to 4 people. There are no restrictions for team members, so you can team up with hackers of any country or experience level! You can also apply together as a team once you've started an individual application. Sign in to your Hacker Dashboard at and navigate to the Team tab to apply!


What if I've never been to a hackathon before?

No worries! It’s helpful to have some programming or technical experience, but it’s not a requirement. We’ll have talks, mentors and workshops to help you with your project; hackathons can be a great place to learn new skills in a short amount of time. Just come eager to learn, excited to meet lots of awesome people, and most importantly, come ready to build.

Can I start working on my hack before the event?

No. In the interest of fairness, students should not be working on their projects before ETHWaterloo begins and we do not allow participants to work on pre-existing projects. However, you can familiarize yourself with all the tools and technologies you intend to use beforehand!

What kind of workshops, talks, and activities will there be?

Talks will be focused on Ethereum development such as using Solidity, state channels, testnets, and other such topics. Schedule to be announced soon.

What about hardware?

If you have specific hardware in mind, bring it with you. We will be doing our best to lend hardware at the event and enable you to work on your dream hack. More details about this will be provided closer to the event.

How does judging work?

A panel of some of the biggest names in tech will evaluate hacks based on creativity, technical difficulty, design, and usefulness. The top 10 overall projects will demo what they have built in front of all of ETHWaterloo during our closing ceremonies. New judges will be announced on a rolling basis on Twitter and Facebook, so make sure to follow us!
