This tutorial shows you how to use Chainlink Automation to automate your Chainlink Functions. Automation is essential when you want to trigger the same function regularly, such as fetching weather data daily or fetching an asset price on every block. After you deploy and set up your contract, Chainlink Automation triggers your function according to a time schedule.

This tutorial shows you how to run computations on the Chainlink Functions Decentralized Oracle Network (DON). The example code computes the geometric mean of numbers in a list. After OCR completes offchain computation and aggregation, it returns the result to your smart contract.

In this tutorial, you will use Chainlink CCIP to transfer tokens from a smart contract to an account on a different blockchain. First, you will pay for the CCIP fees on the source blockchain using LINK. Then, you will use the same contract to pay CCIP fees in native gas tokens. For example, you would use ETH on Ethereum or MATIC on Polygon.
