What is the Kraken minimum trading fee?

Could you please clarify the specifics regarding the Kraken minimum trading fee? I'm interested in understanding the minimum amount that I would need to pay for executing trades on the Kraken platform. Is there a fixed amount, or does it vary based on factors such as the trading volume, the type of currency being traded, or the user's account status? Additionally, are there any other fees that traders should be aware of when using Kraken, aside from the minimum trading fee? Your insights would be greatly appreciated.
