Are we capable of checking LINK balance like this? Lesson - 9 (14:45:47)

[0xrishavsharma]

Hey everyone,
I am a little curious, when we are checking the balance of the Raffle contract here(Screenshot attached below).

Are we able to check if we have LINK in our subscription or not?
As we are just using

bool hasBalance = (address(this).balance > 0);

I thought the balance stays in the Keepers and VRF dashboard and not gets transferred to the contract.

Also, what happens if we transfer the balance of the account, will LINK also get transferred?

The question is raised in "Lesson 9: Hardhat Smart Contract Lottery" at 14:45:47

@rishavsharma-eth address(this) means contract. We are passing the current contract address with this keyword. And etherum-based smart contracts store the balance in Wei, when you transfer the amount of contract only the amount of contract(Wei) will be transferred.

Hope it clears your queries!

@rishavsharma-eth Do you have a timestamp of that? Provide me so I can see what Patrick said.

Yes, I have already mentioned the timestamp in the title and in the question description itself.

Here it is again 14:45:47

Also, see the screenshot above and below, Patrick has mentioned in point number 3, we are checking the subscription is funded with LINK.

@rishavsharma-eth He has mentioned at point no 2 (have some ETH) that we are checking here, and about a subscription with Link so it is pointing to VFR subscription at vrf.chain.link.

Hey @ali-thegilfoyle,
Thanks again for replying.

It was a small doubt but I made it big.
That's right! He wrote that statement to check if the contract has ETH in it or not and understood about the subscription part as well.

Thanks again Ali.
Have epic days ahead :)
