Chainlink's decentralized oracle network provides reliable, tamper-proof inputs and outputs for complex smart contracts on any blockchain.
Use decentralization, trusted nodes, premium data, and cryptographic proofs to connect highly accurate and available data/APIs to any smart contract.
Build on a flexible framework that can retrieve data from any API, connect with your existing systems, and integrate with any blockchain, now and in the future.
Integrate battle-hardened and time-tested oracle solutions that secure billions of dollars in value for market-leading blockchain projects.
Independently monitor and verify Chainlink’s open-source code, the performance of its oracle networks, and the quality of individual node operators.
Chainlink greatly expands the capability of smart contracts by enabling access to real-world data, events, payments, and more without sacrificing the security and reliability guarantees inherent to blockchain technology.
Chainlink is open-source technology that is collectively developed by a large community of developers, researchers, and users who share the goal of building Chainlink into a public good for the benefit of the entire blockchain ecosystem.
