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 — 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.
Requirements: ✅ Goal: Build, simulate, or deploy a CRE Workflow that’s used as an orchestration layer within your project. ✅ Your workflow should:
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.
For projects that use Chainlink Confidential Compute (early access) for private transactions and/or CRE’s Confidential HTTP capability to build privacy-preserving workflows, where API credentials selected request and response data, and value flows are protected, and sensitive application logic executes offchain. This track focuses on applications that require secure API connectivity and/or compliant non-public token movement, enabling decentralized workflows without exposing secrets, sensitive inputs or outputs, or internal transaction flows onchain.
