When using chainlink automation, can another person call my performUpKeep function of smart contract?

Question

Does chainlink automation use my performUpKeep function even though there is onlyOwner modifier ? If so can another person call performUpKeep function of my smart contract ?

I was using chainlink automation on my smart contract function. And i thought if chainlink automation can use my smart contract function directly, can another person call it ? Is chainlink automation safe ?

Hello Tuvshuu kun

No, the performUpKeep function will not work if you add an onlyOwner modifier, if the address is who deployed the contract (concept of owner).

But you can restrict it using onlyKeeperRegistry.

The EthBalanceMonitor Contract use this concept, it can be useful for you :)
