Trading fees on Perpetra are set by the Lighter protocol, not by Perpetra. Perpetra does not add a markup or take a cut of your trades.

​
Trading Fees

At the time of writing, the Lighter deployment on Robinhood Chain charges 0% maker and 0% taker fees across all 39 markets.
Zero fees are a property of the current deployment, not a permanent guarantee. The live rate for a market is always shown in the app before you confirm an order — check there rather than relying on this page.
Maker — You add liquidity (limit orders that sit in the book)
Taker — You remove liquidity (market orders or aggressive limits)

​
Funding Fees

Perpetual contracts have funding to keep the perp price in line with spot. Periodically, longs and shorts settle against each other:
  • Perp above spot → longs pay shorts
  • Perp below spot → shorts pay longs
The funding rate is a percentage of position notional and is set by the protocol per market. High funding can make holding a position expensive — check the rate before sizing up.

​
Liquidation Costs

If your margin ratio falls below the maintenance requirement, the protocol liquidates your position and a liquidation penalty is taken from your remaining margin. The penalty is defined by the Lighter protocol and varies by market. See Liquidations for how the process works and how to avoid it.
Leverage amplifies risk. A 10% move against you at 10x wipes your margin. Size positions conservatively and monitor them.

​
Spot Fees

Spot swaps route through Rialto. The cost of a spot trade is the price impact and the underlying pool fees on the route Rialto picks — both are reflected in the quote you see before confirming. You also set your own slippage tolerance in the app.

​
Gas

Robinhood Chain uses ETH for gas. You pay gas on deposits, withdrawals and spot swaps. You do not pay gas per perp order — those are signed with your delegated trading key and submitted off-chain.

​
How Fees Are Charged

Perp trading fees, when non-zero, are charged in USDG and added to your cost basis, so they affect realized PnL when you close. Funding accrues on open positions and settles at funding time or on close.
