Fees
What a trade costs
Supplying and withdrawing are free
Moving USDC into and out of Hyperliquid's lending pool costs nothing, so Perps can supply idle USDC and pull margin back as often as you trade.
Deposits come from Arbitrum, at least 5 USDC, and your wallet pays Arbitrum's network fee for the transfer.
Hyperliquid keeps 10% of borrow interest
Borrowers pay interest on the USDC they borrow. Hyperliquid keeps a tenth of it as a buffer against liquidations that can't cover their debt; suppliers share the rest. The supply rate today is 3.52%.
Trading fees are set by Hyperliquid and fall as your volume grows. Hyperliquid's fee schedule.
Nothing on top
Open appPerps is a front-end on Hyperliquid. It doesn't touch your trades' prices or your interest.
Hyperliquid's fees, nothing else.
Hyperliquid lets a front-end add a fee to the orders it sends, only after your wallet approves it.
A Hyperliquid feature front-ends can use.
From Arbitrum, minimum 5 USDC.
