You pay the exchange's trading fees, plus a 0.025% builder fee to Hypurr Desk on the orders it sends. Both are counted in every size and every profit and loss the ticket shows.
Exchange fees
At the base tier the exchange charges 0.045% as a taker (an order that fills at once) and 0.015% as a maker (a resting limit order that gets filled). Your account's own rates are used when they are lower. Opening and closing a position each pay a fee.
The Hypurr Desk fee
Hypurr Desk is a Hyperliquid builder: with your approval, each order it sends carries a fee of 0.025% of the order's value (2.5 basis points). The exchange collects it with its own fee.
- It applies to entries, stop losses, take profits and closes.
- Cancels, leverage changes and trailing stops carry none.
- Nothing is charged until you approve it. Approval is the second signature of Start trading, without gas, and it is required to place new entries.
- Closing positions, moving stops and cancelling orders never need it.
- Settings → Account → Builder fee shows the fee, the address it is paid to and its status. You can revoke it there at any time; new entries then ask for it again.
The exchange caps builder fees on perpetuals at 0.1%. The fee is paid to 0x6B2C…8Dc2; Settings shows the full address.
Where you see it
The ticket shows the fee to open an order, for example "$1.24 · 0.045% + 0.025% app"; its tooltip spells out the taker and maker rates and that closing pays again. Position sizes, reward : risk, trailing stops and P&L previews all include it, and an open position's P&L counts the fees you paid to open it and the fee to close it. The status bar's Disclosures link sums up fees and risks on one page.
Other costs
- Funding: perpetuals pay or receive funding every hour. The ticket's details estimate it for the order, and the calendar lists it per day.
- Deposits and withdrawals: Circle's forwarding fee on Arbitrum, 0.20 USDC at the time of writing, and network gas. See Deposits and withdrawals.
- Slippage: market orders and stops fill at the price available, which can be worse than the trigger in a fast market.
