V3 fees apply to executed fills. Takers pay for removing liquidity, while eligible makers can receive rebates for supplying it. Fees are configured per market and can differ by account; always review the fee shown for your order before signing. Order-book execution has no separate interface fee; wallet setup transactions can still incur network fees.

​
Market fee schedule

The maker column shows a negative fee: SAUCE/HBAR’s −0.05% means a rebate of up to 0.05% of the filled value, before the safety cap. One basis point (bp) equals 0.01%. These baseline rates follow the V3 fee policy. Your effective fee depends on your account tier and the rebate cap. See V3 markets for minimum orders and how market parameters can change.

​
Maker rebate safety cap

The applied maker rebate cannot exceed 25% of the effective taker fees collected on the fill, after xSAUCE discounts. This prevents rebates from exceeding their funding source. A quoted maker rebate can therefore be reduced when the counterparty’s taker discount lowers the fee collected.
Assume a SAUCE/HBAR fill with a value equivalent to 1,000.Atthe20bpstakerfee,anaccountwitha201,000. At the 20 bps taker fee, an account with a 20% xSAUCE discount pays 16 bps, or 1.60.The maker rebate is capped at 25% of 1.60,or1.60, or 0.40. Although the market’s listed maximum rebate is 5 bps (0.50onthisfill),theappliedrebatecannotexceed0.50 on this fill), the applied rebate cannot exceed 0.40. The example isolates fee allocation and does not model settlement costs or token-price changes.
Maker rebates are paid from trading fees, not from Masterchef emissions or Liquidity-Aligned Reward Initiative (LARI) rewards. A resting order earns no rebate merely for being present on the book; it must receive an eligible maker fill.

​
xSAUCE fee discounts

Holding xSAUCE gives your account a tiered discount on the market’s baseline fee schedule. Your xSAUCE balance determines your tier: A discount reduces a positive taker or maker fee. If the maker fee is negative, the tier can increase the rebate, but the rebate safety cap still applies; holding more xSAUCE does not guarantee a larger payment on every fill. To acquire xSAUCE through staking, see Single-sided staking.

​
Check the effective fee

The API expresses fees in pips: 1 pip = 0.0001%, and 100 pips = 1 bp. The capFractionPips field expresses the rebate cap as a fraction of effective taker fees; it is not a separate trading fee. See the Orderbook API reference for the units and authentication requirements.
Market makers, API users, and enterprise participants may have separate written fee or rebate programs under the terms of service. Public market parameters do not establish an account’s eligibility for those programs.

​
Where net fees go

After applicable trader discounts and maker rebates, V3 net fees fund SAUCE buybacks through Unified BrewSaucer. Purchased SAUCE is allocated 40% to Mothership/xSAUCE, 30% to the Development Fund, 10% to burn, and 20% to the protocol-owned liquidity (POL) + Incentive Reserve. See SAUCE tokenomics for the full Unified BrewSaucer allocation and the separate devcut burn.
