Securely connect smart contracts with off-chain data and services. Chainlink decentralized oracle networks provide tamper-proof inputs, outputs, and computations to support advanced smart contracts on any blockchain.
Reliable, tamper-proof network
Use decentralization, trusted nodes, premium data, and cryptographic proofs to connect highly accurate and available data/APIs to any smart contract.
Seamless connection to any API
Build on a flexible framework that can retrieve data from any API, connect with existing systems, and integrate with any current or future blockchain.
Proven, ready-made solutions
Integrate pre-built, time-tested oracle solutions that already secure tens of billions in smart contract value for market-leading decentralized applications.
Secure off-chain computation
Use a decentralized network of Chainlink Keeper nodes to automate contracts, mitigating risk of manual interventions and centralized servers.
