Fee tier
A fee tier is a discount level within an exchange's fee schedule, usually unlocked by 30-day trading volume or asset balance. Higher tiers pay lower maker and taker rates.
Exchanges segment traders into tiers because volume is valuable to them: deep, active markets attract more traders. A typical ladder starts at a base tier for everyone and steps down fee rates as your rolling 30-day volume crosses thresholds — often starting around hundreds of thousands of dollars and reaching institutional levels in the tens of millions.
Tiers reset with your volume. Traders whose activity fluctuates can drop back to a worse tier in a slow month, which makes tier-based savings unreliable for anyone below consistent high volume. Some exchanges add alternative unlock paths, like holding the exchange token.
Tier discounts and fee rebates stack — they are independent mechanisms. The tier lowers the rate you are charged; the rebate returns 50–67% of whatever you were charged. For most retail traders who never leave the base tier, the rebate is the larger and more dependable of the two savings.
