FAQs

Who can participate?

Anyone from anywhere in the world can participate. Read all Rules and Code of Conduct here.

How much does it cost to attend?

Nothing, the event is free.

How many people can be on a team?

1-5 people per team.

What if I've never been to a hackathon or worked with Chainlink before?

No worries! It’s helpful to have some software engineering experience, but it’s not a requirement. Projects also often need designers, front end engineers, project managers, and more. We will also have talks, workshops, and mentors to help you with your project. This is a great place to learn all things blockchain and smart contracts.

When can I start working on my project?

As soon as the hackathon opens. To keep the playing field fair, we don’t allow teams to begin building prior to the start of the hackathon. If your project is an upgrade to an existing project, please check with us beforehand.

How will this virtual event take place?

This event takes place 100% online. The hackathon chat/support happens on Discord, workshops happen over Zoom and projects are submitted through Devpost.

What is Chainlink?

Chainlink is a decentralized oracle network that provides secure and reliable inputs and outputs for complex smart contracts on any blockchain. Chainlink Price Data secures billions of dollars in value across top Defi projects.
