- CENShell$2,000
- CFlow Broker$2,000
Prize details
Build your first workflow with CRE! Chainlink Runtime Environment (CRE) is an all-in-one orchestration layer that enables developers to build institutional-grade smart contracts — data-connected, compliance-ready, privacy-preserving, and interoperable across blockchains and traditional systems. With CRE, you can connect blockchains to external APIs, enterprise systems, data sources, LLMs, or AI agents. Using the CRE SDK (available in Go and TypeScript), you’ll build Workflows — modular programs that orchestrate logic across on-chain and off-chain environments. With the CRE CLI, you can compile, simulate, and deploy these workflows to CRE, where they run on a Decentralized Oracle Network (DON) for fault-tolerant execution.
Qualifications
Requirements: ✅ Goal: Build, simulate, or deploy a CRE Workflow that’s used as an orchestration layer within your project. ✅ Your workflow should: - Integrate at least one blockchain with an external API, system, data source, LLM, or AI agent. - Demonstrate a successful simulation (via the CRE CLI) or a live deployment on the CRE network. - Be meaningfully used in your project 💡 If you show us a successfully simulated workflow execution, our team will deploy it to the live CRE network for you during the hackathon!
