What are the fee tiers in V3?

Excuse me, could you please elaborate on the fee tiers in V3? I'm curious to know what the different tiers are and how they might impact the overall costs of using the platform. Are there any benefits associated with higher tiers, or are they simply based on transaction volume? Additionally, how does one qualify for each tier and are there any specific requirements that need to be met? I'd appreciate any insights you could provide on this matter.
