The industry standard oracle network for powering trust-minimized applications across Web2 and Web3 ⬑
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 β 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), youβll build Workflows β 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.
πRequirements:
β Goal: Build, simulate, or deploy a CRE Workflow thatβs used as an orchestration layer within your project.
β Your workflow should:
π‘ If you show us a successfully simulated workflow execution, our team will deploy it to the live CRE network for you during the hackathon!
Build something awesome using Chainlink! Specifically 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.
πRequirements:
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.
Build with Chainlink Confidential AI to bring private data into Web3 applications through trusted AI inference! Using confidential compute and Trusted Execution Environments (TEEs), developers can securely analyze documents, financial records, identity information, and other sensitive inputs while keeping the underlying data private.
Create applications for private credit scoring, under-collateralized lending, KYC/AML, compliance automation, AI-powered attestations, smart notaries, reputation systems, or entirely new use cases. Whether you're building a DeFi protocol, AI agent, consumer application, or institutional workflow, Chainlink Confidential AI enables trusted decision-making without exposing sensitive information.
πRequirements:
β Goal:
β Your project should:
Build a meaningful upgrade to an existing project using Chainlink technology!
We're looking for teams that enhance an existing application, protocol, or infrastructure by integrating Chainlink services to unlock new functionality, improve security, or create a better user experience.
Eligible Chainlink technologies include: Chainlink Runtime Environment (CRE) CCIP (Cross-Chain Interoperability Protocol) Chainlink Confidential AI Price Feeds Data Streams Proof of Reserve (PoR) VRF (Verifiable Random Function)
Important: Please use CRE instead of Chainlink Functions or Automation. Functions and Automation are being deprecated, and projects requiring this type of functionality should implement it using CRE.
