Kuest charges takers with a category-specific curve. Your site receives a configurable share of the final taker fee and can share that operator amount with affiliates. Maker fees are a separate optional flat fee.
Kuest maker fee and the recommended operator maker fee are both 0%. The operator taker setting is a share of the final fee, not a flat percentage of trade value.

​
Kuest fee base

The Kuest component is calculated for every fill:
price is expressed from 0 to 1, and exponent is currently 1. The curve is highest at 50¢ and symmetric around the midpoint. This is Kuest’s own versioned table. Native and mirrored markets both use the local category. An unclassified market remains fee-free until reviewed. The fee base uses integer arithmetic and half-up rounding to five USDC decimal places. Values below 0.00001 USDC are charged as zero.

​
Operator taker share

The operator receives a share of the final taker fee. The initial allowed range is 20–45%, and a new or unregistered builder uses 30%.
The gross-up is rounded upward at five decimal places. Integer division dust remains in the Kuest component.
The chart illustrates how the category curves change across share prices for 100 shares. Your selected operator share is applied through the gross-up above: at the recommended 30%, the final fee is the Kuest fee base divided by 70%, and your site receives 30% of that final amount.

​
Example

For 100 Crypto shares at 50¢ and the recommended 30% operator share: An order without a registered builder pays the same total. Its default operator portion is classified as UNASSIGNED_BUILDER, but both components are credited to Kuest. Registering the builder at 30% changes the receiver split without changing the trader’s total fee.

​
Maker fee

The maker setting is independent and flat on filled cash value. It starts at 0% and is initially capped at 1% for the operator. Kuest also has an independent maker setting that starts at 0%.
Recommended: 0%. Maker fees may reduce liquidity.

​
Affiliate split

Affiliate percentage applies only inside the operator amount:
It does not change what the trader pays and never reduces the Kuest component.

​
Maker Rebates and Liquidity Rewards

  • Maker Rebates reserve the category percentage from confirmed Kuest fee amounts for each market and daily epoch.
  • Liquidity Rewards reserve a configurable share of each creator’s confirmed Kuest fees. Fees from one UTC epoch fund that creator’s eligible markets in the next epoch, according to their configured weights and caps.
  • Operator, affiliate, maker-flat, and UNASSIGNED_BUILDER amounts do not fund either program.
Maker Rebates and Liquidity Rewards are independent. A resting order can earn a Liquidity Reward and also receive a Maker Rebate when it fills.

Who funds what

​
Admin settings

Taker share

Use the slider to select 20–45%. New sites start at the recommended 30%. The chart previews the Kuest component, your site’s component, and the final total across prices and categories.
The advanced maker setting accepts 0–1%. Keep it at zero unless you deliberately want to charge makers.
Choose how much of your operator amount is paid to the affiliate that referred the trader.
The receiver must be your deployed Deposit Wallet. On Amoy, the page identifies the field as Polygon Amoy. Use Use my deposit wallet when the stored receiver differs.
Claimable balances are read from the current CTF and NegRisk Exchanges. Connect the receiver wallet to claim; the interface excludes replaced Exchange addresses.

Range, default share, maker caps, Kuest maker fee, and maxFeeRateBps are Exchange-admin settings. Change both Exchanges together while trading is paused, verify their getters, let the CLOB and orderbook subgraph synchronize, and resume only after both report the same policy.
