Chainlink CRE
The Chainlink Runtime Environment lets institutions build workflows that span blockchains, off-chain systems, and existing financial infrastructure in one place. LinkRiver has helped operate it since its 2025 mainnet launch.
Bringing a financial product on-chain has meant stitching together data feeds, cross-chain messaging, compliance checks, and connections to core banking systems, each integrated separately. CRE replaces that with a single environment where one workflow can read from multiple chains, call authenticated APIs, run computation, enforce compliance, and write results back on-chain or off, composing Chainlink's services, including CCIP and its data and compliance capabilities, as building blocks.
How it works
Developers write workflows following a simple trigger, action, target pattern, using SDKs in Go or TypeScript. A workflow runs not on a single server but across a decentralized network of independent node operators. Each step is performed independently by multiple operators and reconciled through Byzantine fault-tolerant consensus, so the entire workflow, not just its on-chain portion, inherits the tamper-resistance and availability of decentralized infrastructure.
Reuse Chainlink's data, cross-chain, and compliance services as building blocks rather than re-integrating each one.
Read and write across multiple blockchains and authenticated off-chain systems within a single workflow.
Every operation is independently executed by multiple operators and confirmed by consensus.
Chainlink has also outlined privacy-preserving execution in hardware-isolated environments as part of CRE's direction.
In the market
CRE is new, live on mainnet and rolling out to institutions, but it already underpins production workflows.
CRE was the orchestration layer beneath UBS's tokenized money-market fund (uMINT), which in November 2025 processed a live subscription and redemption — described as the first tokenized-fund workflow of its kind run in production rather than as a pilot. It was executed via Chainlink's Digital Transfer Agent standard.
The EU-regulated exchange 21X uses CRE in production to publish verifiable post-trade market data.
A cross-industry initiative with SWIFT, Euroclear, the DTCC, and more than twenty financial institutions uses CRE to extract, standardize, and distribute corporate-actions data across networks.
Why it matters
For tokenized assets to behave like real financial products, the logic around them, subscriptions, redemptions, NAV updates, compliance, and corporate actions, has to run reliably and verifiably across both blockchains and the systems institutions already use. CRE is positioned as the operating layer for that work, letting an institution connect its own systems and build compliant workflows in a fraction of the usual time.
LinkRiver's role
CRE workflows execute across decentralized oracle networks, and LinkRiver operates within them, running the nodes that perform workflow steps and contribute to the consensus that makes each one verifiable, alongside other independent operators, since CRE's 2025 mainnet launch. It runs on the same bare-metal, multi-continent, human-monitored infrastructure behind every product we operate.
LinkRiver helps secure the networks that run CRE workflows; it does not operate CRE, any single institution's workflow, or any one product on its own.
