Chainlink Runtime Environment (CRE) transforms smart contract development with faster workflows and cross-chain support. Discover how CRE matches Ethereum Virtual Machine’s impact.
What is the Chainlink Runtime Environment (CRE)?
The Chainlink Runtime Environment (CRE) is a groundbreaking platform launched in late 2024 that enables developers to deploy code directly on the Chainlink network without embedding Chainlink-specific code in on-chain contracts. It acts as an operating system for Chainlink, orchestrating complex workflows that integrate price feeds, cross-chain messaging, APIs, zero-knowledge proofs, and compliance checks.
How does CRE simplify smart contract development?
CRE abstracts the complexity of interconnected on- and off-chain systems by managing decentralized oracle networks (DONs) that handle blockchain reads, API data fetching, consensus, and on-chain writing. This abstraction reduces development time significantly, turning months of work into weeks or days, according to Chainlink co-founder Sergey Nazarov.
How to build on the Chainlink Runtime Environment?
Developers can write CRE workflows using JavaScript, TypeScript, or Go. The CRE coordinates the actions of Chainlink’s decentralized oracle networks to ensure cryptographic consensus and deliver results to smart contracts, independent of the underlying blockchain.
The architecture supports multiple chains and includes native features for confidential computing and zero-knowledge proofs, enhancing security and privacy in decentralized applications.
What recent developments showcase CRE’s capabilities?
In mid-2025, Chainlink collaborated with JPMorgan’s Kinexys and Ondo Finance to complete a cross-chain delivery versus payment settlement using the CRE, demonstrating its ability to bridge permissioned payment networks with public blockchains. JPMorgan’s Kinexys is actively working to integrate institutional-grade payment infrastructure with emerging on-chain assets, highlighting CRE’s growing adoption in traditional finance.
Why is CRE considered transformative like the Ethereum Virtual Machine?
The Ethereum Virtual Machine (EVM) revolutionized blockchain by enabling Turing-complete smart contracts, drastically reducing development time and complexity. Similarly, CRE introduces a new layer of abstraction that simplifies the orchestration of complex workflows across multiple blockchains and off-chain systems, potentially accelerating decentralized application development and adoption.
What expert insights support CRE’s impact?
Sergey Nazarov emphasized that CRE’s ability to reduce development timelines and manage complex ecosystems positions it as a transformative technology. Industry leaders at JPMorgan’s Kinexys also recognize CRE’s potential to merge traditional finance with blockchain, underscoring its authoritative role in advancing decentralized infrastructure.
