Polyester charges a trading fee whenever a spot order fills. Your fee rate depends on your VIP tier and whether the fill is classified as maker or taker. For eligible buy orders, you can also choose which asset pays the fee.
There is no fee to place or cancel an order that does not fill.

| Role | When it applies |
|---|---|
| Maker | Your order rests on the order book before another order fills against it. |
| Taker | Your order fills immediately against liquidity already resting on the order book. |
A limit order can be both: any quantity that fills immediately pays the taker rate, while quantity that rests and fills later pays the maker rate.
Maker rebates
Polyester supports maker rebates: a negative maker fee credits your account when an eligible maker order fills. Exact maker rebate rates are coming soon and will be published here.
Pair promotions
A Pair can run a promotion that lowers the VIP tier rates on that market, for maker fees, taker fees, or both. Promotions apply automatically, and your rate returns to normal when the promotion ends.
When a promotion or an account discount applies, the Fees row in the Order Form shows your lower rate above your struck-through VIP rate. Hover over it to see each discount, what it takes off, when it ends, and Your rate. Select the row to open the Fee Schedule.
Choose how your fee is paid
Most exchanges decide the fee asset for you. On Polyester, an eligible buy order lets you switch Fee Asset, under Advanced in the Order Form, between the two Assets in the Pair. Your choice appears again when you review the order.
- The quote asset pays the fee with the Asset you are spending. When buying BTC/USDT, select USDT.
- The base asset deducts the fee from the Asset you receive. When buying BTC/USDT, select BTC.
The percentage rate does not change. The fee is calculated in the selected asset:
| Fee Asset | Calculation | Effect on a buy order |
|---|---|---|
| Quote asset | Fill value in the quote asset × fee rate | You spend slightly more quote asset and receive the full base quantity. |
| Base asset | Base quantity received × fee rate | You spend the entered quote amount and receive slightly less base asset. |
Let's say Bitcoin is currently trading at $100,000 and you buy $1,000 of BTC at a 0.08% fee rate.
- Paying in USDT, the fee is 0.80 USDT. You spend 1,000.80 USDT and receive 0.01 BTC.
- Paying in BTC, the fee is 0.000008 BTC. You spend 1,000 USDT and receive 0.009992 BTC after the fee.
Sell-order fees are deducted from the quote asset received from the sale. For example, selling 0.01 BTC for 1,000 USDT at a 0.08% rate returns 999.20 USDT after the 0.80 USDT fee.
How fees are reserved on buy orders
When a buy order pays its fee in the quote asset, Polyester reserves that fee at the highest rate of any VIP tier under the market's fee schedule, not at your own rate. Discounts do not lower it. The reservation is a hold, not an extra charge, but the largest buy your balance allows can be slightly smaller than your own rate suggests.
Each fill charges your actual rate, and the rest of the reserve returns to your Available Balance as the order fills or ends.
- Post-only limit orders reserve at the highest maker rate of any tier.
- Buys sized by a quote amount reserve at the lower of that highest rate and your own taker rate.
Let's say a limit buy is worth 1,000 USDT, the highest rate is 0.10%, and your rate is 0.08%. Polyester reserves 1,001.00 USDT. If the order fills as a taker, the fee is 0.80 USDT and the remaining 0.20 USDT returns to your Available Balance. These are example rates.
Referral discounts and rewards
Referrals are coming soon. This section describes how referral benefits are planned to work; rates may change before launch.
Referral codes affect positive trading fees in two different ways:
| Who receives the benefit | Benefit | What it applies to |
|---|---|---|
| Referred trader | 4% lower trading fees | Positive maker or taker fees on eligible fills |
| Referrer | 15% of the referred user's paid trading fees | The fee remaining after the referred trader's discount |
The referral benefit is calculated from the trading fee, not the order's full value.
Let's say a referred trader completes a $1,000 fill at a 0.08% fee rate:
- The standard trading fee is 0.80 USDT.
- The 4% referral discount saves the trader 0.032 USDT.
- The referred trader pays 0.768 USDT.
- The referrer earns 15% of that paid fee, or 0.1152 USDT.
Referral discounts and rewards apply only when a positive trading fee is charged. They do not create a negative fee or maker rebate.
