Fees
What you actually pay per trade
Quant doesn't charge subscriptions, spreads, or markups. The only fees are the standard Hyperliquid fees plus a 0.05% builder fee that HL collects on our behalf. Every fee is netted against your trade PnL in your history.
Quant builder fee — 0.05%
HL has a built-in mechanism for interfaces to charge a per-trade fee. You approve the rate once during onboarding (see the Connect Hyperliquid section), and HL handles the deduction automatically. The fee is taken from the trade's notional, not your balance.
Hyperliquid native fees
| Fee | Tier 0 (retail) | Notes |
|---|---|---|
| Taker | 0.045% | Charged on the side that hits an existing order book level. |
| Maker | 0.015% | Charged on the side that adds liquidity (sat at price until filled). |
| Funding | Varies | Paid every hour, longs ↔ shorts. HL publishes the current rate per market. |
| Withdraw | Flat $1 | Charged by HL when bridging out to Arbitrum. |
Higher trading volume unlocks tier discounts on HL's side. Funding is the only fee that can be positive — i.e. paid to you — when the market crowd-positioning works in your favour.
How Quant handles fees
- Live agents apply a 10bps buffer to each order's notional. That covers the taker fee + builder fee + slippage so the order isn't rejected for margin shortage once HL accrues fees.
- PnL reporting uses HL's realised closedPnl from userFillsByTime, which is net of HL fees. Builder fees are tracked separately and shown in the position tooltip.
- Funding is currently not attributed to individual trades — it accrues to the subaccount and shows up in your overall balance. Per-trade funding attribution is on the roadmap.
