Prizes

🌎 Connect the World with Chainlink ⸺ $6,000
Up to 3 teams will receive $2,000

Build something awesome using Chainlink! Anything that came from the Chainlink Documentation counts - using CCIP, Price Feeds, Data Streams, PoR or VRF.

Note: Please use CRE instead of using Chainlink Functions or Automation. These products will be deprecated, and any project that needs this type of functionality should use CRE instead.

Qualification Requirements

Requirements:

  • Each project must use a Chainlink service in some form to make a state change on a blockchain, otherwise it will not be eligible for the Chainlink core prizes. This means that a front end simply reading from Chainlink Data Feeds doesn't count. Using Chainlink inside your smart contracts is required.
  • While all project submissions are evaluated holistically, there will be bonus points given to projects that use multiple Chainlink services in a meaningful way.
  • Please let us know how you use Chainlink in the project description.
🔗 Best workflow with Chainlink CRE ⸺ $9,000
Up to 3 teams will receive $3,000

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.

Qualification Requirements

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 đź’ˇ If you show us a successfully simulated workflow execution, our team will deploy it to the live CRE network for you during the hackathon!
