Chainlink Virtual Hackathon: Building Real-World Smart Contracts Using Off-Chain Resources

We believe that enabling off-chain connectivity via secure oracles is the major catalyst that will spark the next evolution in smart contract development. Whether it’s receiving off-chain market data to trigger your DeFi smart contract or connecting to an external payment system to settle it, the range of possible applications that Chainlink opens is limitless.

To accelerate the development of next-generation smart contracts, we are hosting the first Chainlink Virtual Hackathon from October 14th to 31st and invite anyone from around the world to participate. The hackathon is not only a launching pad for developers who want to create useful smart contract dApps, but also an opportunity for people to learn about the growing ecosystem of platforms, data providers, and oracles accessible with Chainlink.

To help you maximize the success of your projects, we will provide participants with direct access to team members and experienced mentors, a plethora of educational materials for learning about off-chain connectivity, live workshops showcasing how to use Chainlink, and much more. Join our Discord to meet other hackers and start planning today!

We also encourage you to use the latest Chainlink resources: new reference data sets for popular price pairs, selection of whitelisted oraclesLinkPool marketplace of 60+ oracle nodes and 250+ tasks, and more.
