fundMe contract - payable function

[minchillo4]

Hello, guys!

My doubt is regarding the function above:
function fund() public payable { require(getConversionRate(msg.value) >= mimimumUsd,"Not enought amount"); }

I thought that the payable modifer allowed my function to recieve funds with the require condition, but I need to deposit funds when deploying the contract. Is that the right flow? Why the payable function forces me to send funds when deploying?

Thanks.

The payable keyword will not force you to send funds while deploying.

Adding the payable keyword in the function's signature will allow us to receive msg.value (funds) inside that function.

require on the other hand will verify that either we have sent the required amount, if not then will throw error (message on the right side).

If you want to add funds when deploying it, you could mark the constructor as payable and pass the amount as an argument.

Make sure you have a withdraw function when sending eth to your contract.
