Chainlink

Securely connect smart contracts with off-chain data and services

Infrastructure
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.
