Lesson 9 - VRF cost 23 LINKs!

[lqpchen]

Hey guys, I used the exact same code from github and is testing on goerli, but the VRF if costing 23 LINKs. Am I missing anything here?

@lqpchen Because the crypto market is very down and link prices are very low that is why they are charging more LINKs for each request to balance the request cost.

Wherever you work with tokens which work on real market value, you should consider market fluctuations.

@alymurtazamemon It's a bit strange, I top up 25 more LINKs and then it moved on and ended up only costing me less than 1 LINK in total. (around 0.6 for two tries)

Hello @lqpchen

It will charge you only something around 1 LINK or even less and as you can see max cost is 23.74 and PROJECTED balance required is 20 LINK as it is some kind of buffor. To sum up it is almost impossible to pay that max 23 LINK's and that 20 is just a buffor to perform transaction but real cost will be less than 1 LINK. I hope it's more clear to you now.

My upKeep:

Thank you. It's clear now
