The Chromion Hackathon Has Officially Concluded
Thank you to all the builders, mentors, judges, and sponsors who made this hackathon possible. Chromion brought together a truly global community of developers and marked another major step forward in showcasing what is possible when powerful infrastructure is put in the hands of creative minds.
Over the course of several weeks, teams built applications that stretched the boundaries of what onchain systems can do. Projects included automated yield optimizers, AI-powered treasury agents, real-world asset platforms, and seamless cross-chain payment infrastructure.
This hackathon highlighted how Chainlink is becoming the critical platform for the most promising Web3 use cases. Developers used Chainlink CCIP as the universal messaging and value transfer layer that connects stablecoins and assets across chains. They used Chainlink Automation and Data Feeds to power secure and verifiable DeFi strategies. Chainlink Functions served as the bridge between offchain data and onchain tokenized systems. Several projects also explored how Chainlink can be combined with AI to enable verifiable onchain decision-making for financial applications.
Together, these projects show how Chainlink provides all the services and tools needed to support the full lifecycle of onchain finance. We look forward to seeing what you will build at the next Chainlink hackathon.
