The most secure, reliable, and cost-effective automation service for Web3 developers

Chainlink Automation enables smart contract developers to innovate, optimize costs, unlock compute power, save time and resources spent on DevOps, and scale faster.

Secure, verifiable, reliable, and performant

Chainlink Automation delivers the strongest security guarantees in the market, with verifiable compute provided via Chainlink's OCR3 consensus mechanism.

Gas and Operations Efficiency

With OCR 3.0 enabling Automation nodes to come to consensus, users can offload their expensive onchain computation offchain to Chainlink Automation’s Decentralized Oracle Network at a fraction of the cost—with the same cryptographic guarantees.

Business-boosting innovation

Discover endless possibilities with log triggers, brand new ways of connecting smart contracts and building autonomous dApps, and massively increased computation power with Verifiable compute.

Automate seamlessly, save time and resources, scale faster

Scale hassle-free, from zero to millions of transactions, and avoid the challenges that come with building and maintaining the infrastructure needed to reliably automate across multiple chains.

Start building with Chainlink Automation

Automate your smart contracts with industry-leading security and reliability guarantees while reducing your gas consumption.

Industry-leading automation powered by a decentralized network

Automation nodes use your triggers and logic to determine what needs to happen onchain (and when). Nodes then come to consensus and the signed report is sent onchain to ensure the computation is verifiable, providing strong security and reliability guarantees.
