# Fees

This page explains every fee you can pay when trading on Wire. There are only **two** kinds of fee, and they behave very differently:

1. **Hyperliquid protocol fees** — set by Hyperliquid, not by us. These vary by your volume tier, discounts, and the type of market.
2. **The Wire builder fee** — the only fee *we* charge, for routing your order.

The trading ticket always shows the **combined, estimated fee for the specific order you're about to place**, in both USD and percent. This page is the reference for *how* that number is calculated.

***

## What you pay per trade

When you enter an order, the ticket shows an **Est. Fees** line:

* The number is your **effective Hyperliquid fee + Wire builder fee** for *that* order (taker for market orders, maker for resting limit orders).
* Hover it for the breakdown (HL fee vs. builder fee).
* The estimate uses your **live, personal** Hyperliquid fee rate, so it already reflects your volume tier and any discounts.

You are never charged more than what's shown, except for price slippage on market orders (a separate, configurable tolerance).

## 1. Hyperliquid protocol fees

These go to the Hyperliquid protocol (and, on HIP-3 markets, the market's deployer). We have no control over them — we read your live rate from Hyperliquid and display it.

### Base rates (Tier 0)

| Market | Taker  | Maker  |
| ------ | ------ | ------ |
| Perps  | 0.045% | 0.015% |
| Spot   | 0.070% | 0.040% |

You have **one fee tier across all assets** (perps, HIP-3 perps, and spot), based on your 14-day rolling volume. Higher volume lowers these rates.

### Discounts (applied automatically)

* **Staking discount** — staking HYPE reduces your fees.
* **Referral discount** — an active referral lowers your taker fee.
* **Aligned-collateral discount** — trading markets that use an aligned quote asset reduces fees.

All three are already reflected in the personal rate Wire reads from Hyperliquid, so the ticket estimate accounts for them.

### Market-structure multipliers

On top of your personal rate, certain markets scale the fee:

* **Spot stable pairs** (both legs are stablecoins, e.g. USDC/USDT): fees are scaled to **0.2×**.
* **HIP-3 builder-deployed perps** (e.g. our TradFi markets): standard HIP-3 markets charge **2× the base perp rate**, split 50/50 between Hyperliquid and the market's deployer. A deployer can configure an extra fee share (0–300%), which raises this further.
* **Growth mode**: when a HIP-3 market has growth mode enabled, fees are reduced by \~90% (**0.1×**) to bootstrap liquidity.

> Example: a standard HIP-3 perp taker at Tier 0 pays ≈ 0.09% (2 × 0.045%) before discounts.

## 2. The Wire builder fee

This is the only fee Wire charges. It's a Hyperliquid **builder code** attached to each order you route through the app.

* **Current fees:**
  * **Perps (long & short):** **0.025%** per order.
  * **Spot sells:** **0.1%** per order.
  * **Spot buys:** **0%** — never charged (see below).
* **Where it applies:**
  * **Perps:** both long and short.
  * **Spot:** **sell orders only.** Hyperliquid collects builder fees only in the quote/collateral asset, so **spot buys are never charged a builder fee** — the ticket shows this explicitly.
* **Protocol caps (hard limits):** **0.1% on perps, 1% on spot.**

### One-time approval

Before your first trade you approve a **maximum builder fee** for Wire's builder address (a single signature with your main wallet). This is a *ceiling*, not the amount charged:

* **Approved ceiling:** **0.1%** — exactly the highest fee charged (on spot sells). Perps and other orders are charged less.
* The actual per-order fee is always shown before you trade and can never exceed the ceiling you approved.

### Revoking

You can revoke Wire's builder permission at any time by approving a new max fee of **0%** for our builder address (on Hyperliquid directly or via a third-party interface). Doing so disables trading through Wire until re-approved.

***

## How the estimate is computed

For a given order, Wire resolves the fee as:

```
HL fee   = your personal HL rate (taker or maker)
           × stable-pair scale (spot)
           × HIP-3 scale × growth-mode scale (perps)

Builder  = 0.025% perps / 0.1% spot sells   (0% for spot buys)

Total    = HL fee + Builder fee
```

* Your personal HL rate comes from Hyperliquid's `userFees` endpoint (tier + staking + referral baked in).
* Market multipliers come from the market's metadata (`perpDexs`, growth-mode flag).
* Until your wallet is connected, the ticket falls back to Tier 0 rates.

***

## FAQ

**Why is my fee different from the headline rate?** Your rate depends on your volume tier and discounts, and on the specific market (spot vs. perp, HIP-3, stable pair). The ticket always shows *your* number.

**Why do TradFi (HIP-3) markets cost more?** HIP-3 markets are deployed and operated by a third party and default to 2× the native perp fee, shared with the deployer.

**Do I pay a Wire fee when buying spot?** No. Builder fees apply to spot sells only.
