Klak is a perpetuals trading interface built on top of Hyperliquid's matching engine and liquidity. You get Klak's design and UX — Hyperliquid handles the blockchain, order matching, custody, and settlement.
Your funds are never held by Klak. Everything is non-custodial and settled on-chain. Klak is purely a frontend — we can't freeze your account, move your funds, or access your wallet.
Klak charges a 1 basis point (0.01%) builder fee on every trade you place through the interface. This is collected automatically by the protocol and credited to Klak.
| Trade size | Klak fee (1bp) |
|---|---|
| $100 | $0.001 |
| $1,000 | $0.01 |
| $10,000 | $0.10 |
| $100,000 | $1.00 |
Standard protocol trading fees also apply separately.
The first time you place a trade on Klak, you'll be asked to sign an EIP-712 message approving the 1bp builder fee. This is a one-time signature — you won't be asked again on subsequent trades.
This approval is stored on-chain and can be revoked at any time by interacting directly with the protocol.
Make sure you have USDC on Arbitrum in your wallet (MetaMask, Rabby, or any injected wallet).
Click Deposit in the top bar to open the deposit flow.
Bridge your USDC from Arbitrum. The transaction typically confirms in under a minute.
Once confirmed, your balance will appear in the Positions panel at the bottom of the trade page.
Currently Klak supports deposits from Arbitrum only. Support for additional chains may be added in future.
Select a trading pair from the pair selector in the top bar. Set your order type (Market or Limit), size in USDC, and leverage. Click Long or Short to submit.
Each order requires a wallet signature — no gas fees, just an off-chain EIP-712 signature that authorises the trade.
Klak defaults to cross margin mode. Your entire account balance is used as collateral across all positions. Liquidation occurs when your account value falls below the maintenance margin threshold.
The estimated liquidation price for each open position is shown in the Positions panel. Trade responsibly — leverage amplifies both gains and losses.
Your funds are held on-chain by the underlying protocol. Klak has zero custody — we are a pure UI layer. If Klak went offline tomorrow, your funds would remain fully accessible via the protocol native interface.
