Does HMRC track Kraken?

I'm a bit curious, does HMRC keep tabs on Kraken? I understand that they monitor cryptocurrency transactions to some extent, but I'm not entirely sure how it works. I use Kraken for some of my crypto trading, and I was wondering if I should be worried about any potential scrutiny from HMRC. Could you please clarify this for me? Also, if they do track Kraken, what kind of information do they collect and how do they use it? Thank you for your time and assistance.
