Fees

Rubicon charges competitive fees for trading. Understanding the fee structure helps you optimize your trading costs.

Trading Fees

Maker vs Taker

Role	Description	Fee
Maker	Adds liquidity (limit order resting on book)	0.03%
Taker	Removes liquidity (market order or crossing limit)	0.081%

Example — $10,000 Trade:

• Maker fee: $10,000 × 0.0003 = $3.00

• Taker fee: $10,000 × 0.00081 = $8.10

Note: HIP-3 perpetuals have slightly higher fees than main Hyperliquid markets.

How to Get Maker Fees

Your order is a maker order when:

• Limit order posted to order book (doesn't immediately execute)

• Fills when another trader crosses your price

Your order is a taker order when:

• Market order (immediate execution)

• Limit order that immediately matches (crosses the spread)

Reducing Fees

1. Use limit orders — Post to book for maker rates

2. Avoid crossing spread — Set limit at or beyond best bid/ask

3. Increase volume — Volume tiers may reduce fees

Fee Calculation

Fees are charged on notional value:

Fee = Position Size × Fee Rate

Example:

Trade: Buy 10 SOXX @ $225
Notional: $2,250
Order Type: Market (taker)
Fee Rate: 0.081%

Fee = $2,250 × 0.00081 = $1.82

Funding Rate Payments

Funding is not a fee — it's a payment between traders:

• Positive funding — Longs pay shorts

• Negative funding — Shorts pay longs

See Funding Rate for details.

Liquidation Penalty

If liquidated, you pay a penalty:

Penalty Type	Rate
Liquidation penalty	~0.5% of position

This funds the insurance pool.

Gas Fees

Hyperliquid is largely gasless:

Action	Gas Cost
Trading	Free (gasless)
Deposits	Arbitrum gas
Withdrawals	Arbitrum gas
Some admin actions	Minimal HYPE

Fee Comparison

How Rubicon compares to alternatives:

Platform	Maker	Taker
Rubicon (HIP-3)	0.03%	0.081%
Hyperliquid (Main)	0.01%	0.035%
Binance Futures	0.02%	0.04%
dYdX	0.02%	0.05%

HIP-3 builder perpetuals have higher fees to compensate for the additional infrastructure and oracle costs.

Calculating Total Trading Cost

For a round-trip trade (open and close):

Total Cost = Entry Fee + Exit Fee + Funding (if holding)

Example — Day Trade:

Entry: Market buy $5,000 @ 0.081% = $4.05
Exit: Limit sell $5,000 @ 0.03% = $1.50
Total: $5.55 (0.111% round-trip)

Example — 3-Day Hold:

Entry: $4.05
Exit: $1.50
Funding: 3 days × 3 intervals × 0.02% × $5,000 = $9.00
Total: $14.55

Fee Optimization Tips

1. Use limit orders for entries and exits — Save ~0.05% per trade

2. Factor funding into hold duration — Short trades avoid funding

3. Check funding before entering — High funding adds to costs

4. Trade larger size, less frequently — Fixed costs per trade add up

5. Consider market hours — Spreads tighter during regular hours
