The idea behind the Chainlink Hackathon is simple: give developers the right combination of tools to build applications that fundamentally change user experiences, community incentives, business processes, video games, and more.
"If you can imagine it, you can build it at Constellation."——Rory, Community Director at Chainlink Labs.
This philosophy was especially true at the Chainlink Constellation Hackathon, as it was the first time Web3 developers had access to Chainlink CCIP and Functions. These two powerful services are designed to be essential components for all Web3 developers and are flexible enough to unlock any use case. With the ability to build secure cross-chain smart contracts and efficiently connect to any API, the Constellation Hackathon reimagines what the future of Web3 will look like.
CCIP and Functions were favorites among Constellation contestants, with many combining multiple services on the Chainlink platform to build next-generation applications.
A huge thank you to all the hackathon participants, judges, sponsors, and mentors for making Constellation the largest event yet.
We are proud to present the winning projects here.
