# V3 fees and rebates

> How SaucerSwap V3 order book fees work: percentage-based taker fees and maker rebates, xSAUCE fee discounts, fee caps, and the BrewSaucer buyback flow.

V3 charges fees on order book fills. Fees are set per market and per side (maker or taker), can differ by account, and are designed so that takers fund the system: maker rebates, where active, are paid out of taker fees rather than token emissions.

<Info>
  This page shows fee rates as percentages, with basis points in parentheses. The API fields — `takerFeePips`, `makerFeePips`, and `capFractionPips` — return raw pips, where 1 pip = 0.0001% and 100 pips = 1 basis point. Convert those values before displaying them to users.

## Launch baseline and live rates

[V3 Launch Economics, thread 368](https://gov.saucerswap.finance/t/v3-launch-economics/368), proposal 6123, and final passing election 6141 ratified this public launch baseline:

| Market class          | Taker · maker                                         |
| --------------------- | ----------------------------------------------------- |
| Non-stable markets    | 0.12% (12 bps) taker · 0.002% (0.20 bps) maker rebate |
| Stable–stable markets | 0.06% (6 bps) taker · 0.0005% (0.05 bps) maker rebate |

Market and account configuration can differ from this baseline. Read the effective values live:

| Surface                                          | What it shows                                                                   |
| ------------------------------------------------ | ------------------------------------------------------------------------------- |
| `GET /books`                                     | Public per-market baseline fields, including `takerFeePips` and `makerFeePips`  |
| Trade page order preview                         | The fee applied to your order before you sign it                                |
| `GET /fees/:orderbookId?side=maker` (or `taker`) | Your account's fee rates for a market, in pips (requires wallet authentication) |

See the [Orderbook API reference](/api-reference/orderbook/overview) for authentication and endpoint details.

<Info>
  [Thread 385](https://gov.saucerswap.finance/t/v3-order-book-calibration-contract-migration-market-set-and-fee-configuration/385), proposal 6285, and final election 6296 ratified a later order-book recalibration on July 22, 2026, but that configuration is not verified as deployed. Checked July 29, 2026: the five public mainnet books still reported the 12/6 bps launch taker schedule, while every public `makerFeePips` field reported `0`. A rebate is not proven active for a specific account unless its authenticated fee response or order preview shows it.

## Takers pay, makers may earn

* **Taker fees.** Orders that remove liquidity from the book pay the market's effective taker fee on the filled amount.
* **Maker fees and rebates.** A negative maker fee is a rebate funded from taker fees. The effective maker value may be zero or account-specific, so verify it before placing an order.
* **Fee caps.** Markets carry a fee-cap parameter (`capFractionPips`) that bounds the fee actually charged on a fill. The fee you sign against is the most you pay.

<Note>
  Per the [terms of service](/legal/terms-of-service), market-maker, API, and enterprise participants may operate under separate written programs with different fee tiers, rebates, or limits. Public docs describe the public schedule only; see [Market makers](/resources/market-makers) for the onboarding path.

## xSAUCE fee discounts

Holding xSAUCE (staked SAUCE) earns tiered multipliers on a market's baseline fee schedule: positive fees are reduced, and negative maker rebates are increased. Current tiers and thresholds are shown in the web app; your effective rates always come from the fees endpoint or the order preview. To stake, see [Single-sided staking](/protocol/single-sided-staking).

## Where fees go

Net order book fees — taker fees collected minus maker rebates paid — fund SAUCE buybacks through BrewSaucer. Under election 6141, V3 buyback proceeds are allocated 30% to xSAUCE, 60% to Development, and 10% to burn; the POL and incentive-reserve allocation is 0%. See [SAUCE tokenomics](/tokenomics/overview) for the source-specific matrix.
