### checkUpkeep function

This view function contains the logic that runs offchain during every block as an [`eth_call`](https://eth.wiki/json-rpc/API#eth_call) to determine if `performUpkeep` should be executed onchain. To reduce onchain gas usage, attempt to do your gas intensive calculations offchain in `checkUpkeep` and pass the result to `performUpkeep` onchain. It is a best practice to import the [`AutomationCompatible.sol`](https://github.com/smartcontractkit/chainlink/blob/develop/contracts/src/v0.8/automation/AutomationCompatible.sol) contract and use the `cannotExecute` modifier to ensure that the method can be used only for simulation purposes.
