# Fees & Referrals

> Trading and referral fee structure.

United Market applies a fee on trading. Referral rewards are paid as a share of the
platform fees generated by users you refer.

## Fee Structure

| Fee             | Rate    | Applies To                                                                  |
| --------------- | ------- | --------------------------------------------------------------------------- |
| Trading fee     | `0.15%` | Charged on each executed trade (both sides). Configurable per market / tag. |
| Referral reward | `30%`   | Of the platform fees generated by users you referred.                       |
| Claim fee       | `1%`    | Coming soon — not currently charged.                                        |

## Notes

* The trading fee defaults to `0.15%` and follows Polymarket's symmetric model: at a
  mid-market price it is \~`0.15%` of notional and tapers toward the price tails. It is
  configurable per market and per tag.
* Referral rewards are `30%` of the eligible platform fees generated by referred users,
  attributed on a **first-touch** basis (the first valid code a new user signs up with).
* Referral rewards accrue weekly and are paid **retrospectively in POINTS** (1 POINTS =
  1 USDC of value). A minimum of **1 POINTS** is required to be paid out; amounts below
  the threshold carry over to the next payout.
* The `1%` claim fee is **deferred** and not charged today (it cannot be enforced on the
  current direct redemption path).
* Final amounts may vary slightly due to token decimals and on-chain rounding.

## Using the API

* A market's effective trading fee is exposed at `GET /markets/{id}/fee` as `feeRateBps`
  (basis points). Sign this exact value into your order's `feeRateBps` — see
  [Place an Order](/guides/place-order).
* Resolve a referral code to its owner with `GET /referral/resolve/{code}` (public).
* Signed-in users can fetch their own code (`GET /referral/code`), record first-touch
  attribution (`POST /referral/attribution`), and view rewards (`GET /referral/summary`).
