# Chainlink

> Oracle data and cross-chain infrastructure for smart contracts

Chainlink provides infrastructure that connects smart contracts with external data, other blockchains, and existing systems. Developers can use its data services to bring market information into an application, or its Cross-Chain Interoperability Protocol to transfer tokens and messages between supported networks. These capabilities support workflows such as lending, trading, and managing tokenized assets.

The Chainlink Runtime Environment also lets teams combine data sources, contract interactions, and other operations into programmable workflows. Documentation, tutorials, and SDKs guide developers through choosing a service, testing an integration, and deploying it, while monitoring tools help track cross-chain transactions once an application is running.
