Chainlink

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. Start building your hybrid smart contract with Chainlink. 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 existing systems, and integrate with any current or future blockchain. Integrate pre-built, time-tested oracle solutions that already secure tens of billions in smart contract value for market-leading decentralized applications. Use a decentralized network of Chainlink Automation nodes to automate contracts, mitigating risk of manual interventions and centralized servers.
