#Fee Structure

Exolane is designed to have minimal and transparent fees. This page explains every fee you may encounter.

#Fee Summary

#Trading Fees

#Taker Fee: 0.02%

Applied when you open or close a position.

Fee = Position Notional Value × 0.02%

#Examples:

#Maker Fee: 0.00%

There is no maker fee on Exolane. Market makers and liquidity providers pay nothing.

#Fee Calculation Examples

#Opening a Long Position

Position: Buy 0.1 BTC at $100,000
Notional Value: 0.1 × $100,000 = $10,000
Taker Fee: $10,000 × 0.02% = $2.00

#Closing a Position

Position: Sell 0.1 BTC at $105,000
Notional Value: 0.1 × $105,000 = $10,500
Taker Fee: $10,500 × 0.02% = $2.10

#Round Trip (Open + Close)

Open: 0.1 BTC at $100,000 → $2.00 fee
Close: 0.1 BTC at $105,000 → $2.10 fee
Total Fees: $4.10
Profit: $500 - $4.10 = $495.90
Fee % of Profit: 0.82%

#Liquidation Fees

#Liquidation Penalty: 0%

Unlike most exchanges, Exolane charges no liquidation penalty.

#What Happens at Liquidation:

1. Position is closed at oracle price
2. Outstanding debts are settled
3. Remaining collateral returns to you
4. Liquidator receives only gas reimbursement

#Why No Penalty?

• Liquidations maintain system solvency, not punish users
• Removes incentive for predatory liquidation hunting
• Keeps more value with the user

#Keeper Fees

Exolane uses an intent-based execution model. When you place a trade, you sign an intent that a keeper (relayer) executes on-chain on your behalf. The keeper is compensated with a small fee deducted from your collateral account (not your wallet ETH).

#Automatic Collateral Reserve

To ensure keeper fees can always be paid, the protocol maintains a minimum reserve in your collateral account. If your balance drops below $0.30, the SDK will automatically pull up to $3.00 from your safest market position back into your collateral account before executing your trade — all in a single atomic transaction.

This is seamless and invisible to you. For full details, see Collateral & Margin → Automatic Collateral Reserve.

#Gas Costs

All transactions require gas paid in ETH:

#Funding

Funding is a periodic payment between long and short traders, designed to balance open interest.

• 100% of funding flows directly between traders
• The protocol does not take any share of funding
• The funding rate is capped at ±15% APR per market
• See Funding Rates for details

#Fee Disclosure

#Optimizing Costs

#1. Use Appropriate Leverage

Lower leverage = smaller position = lower absolute fees

#2. Trade Larger Sizes (If Comfortable)

Fee percentage is the same, but relative to potential profits

#3. Watch Funding Direction

Trading the "receiving" side earns you funding

#4. Use Limit Orders Strategically

Same fee, but potentially better entry prices

#5. Batch Operations

Fewer transactions = less gas

#Where Do Fees Go?

Trading fees support:

• Protocol development and maintenance
• Security audits
• Infrastructure costs
• Future development

Fees do not go to:

• Insider profit extraction
• Unnecessary overhead
• Hidden parties
