The Layer 2 Hackathon, co-organized by Chainlink and IOSG Ventures in Shanghai, concluded with 109 project submissions, where 14 used Chainlink to create hybrid smart contract applications. The event highlighted the rapid development of working prototypes and the potential of connecting smart contracts to external data via Chainlink's decentralized oracle networks. The top five projects received a share of $8,000 in prizes, with the grand prize going to Objk for a middleware solution that enhances the Synthetix debt pool by using Chainlink data feeds. Other notable projects included AcySwap, FluidDAO, BoboSwap, and Metaficate, each integrating Chainlink for various innovative applications in decentralized finance and blockchain technology. The hackathon celebrated the diverse use cases and potential of layer 2 technology, and Chainlink continues to support the smart contract ecosystem through upcoming hackathons and developer resources.
