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.

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. Its Price Feeds are securing hundreds of millions of dollars by top Defi projects including Synthetix, Aave, Loopring, Set Protocol and more.
