How the CryptoBoost fee works: 0.1% per order

The rule

Fee = 0.1% × the value of each order the bot places. It applies to opening, adding to and closing positions. It is the only fee CryptoBoost charges.

The fee uses Hyperliquid's builder fee: a feature that lets an app add a capped fee to the orders it sends for you. Hyperliquid takes the fee from your account as the order fills and pays it to CryptoBoost. For what the approval does and does not allow, see what permissions a Hyperliquid bot needs.

CryptoBoost changed to this fee in October 2026. It replaces the earlier 10% fee on monthly trading profit.

What a trade costs

The fee is a percentage of the position, not of your deposit or your profit. With leverage, the position is larger than the money in your account. For example, 3,000 USDC at 3× leverage can hold a 9,000 USDC position:

That is 0.2% of the position, or 0.6% of the 3,000 USDC in the account, for one trade. If the bot adds to a position in steps, each step is a separate order with its own fee. Order values change with the BTC price, so real figures will differ.

Hyperliquid's own trading fee is charged on the same orders, separately. At Hyperliquid's base fee tier it is 0.045% per order for orders that fill immediately, which would add about 8.10 USDC to the trade above. Funding on open positions is also separate, and can be positive or negative.

Losing trades and losing months

The fee does not depend on whether a trade makes money. A losing trade pays the same fee as a winning one, so a losing month still has fees. The more often the bot trades, the more fees you pay.

Example: in a month, the bot completes 10 trades of 9,000 USDC each. The CryptoBoost fees total 10 × 18 = 180 USDC, whatever the month's result.

Weigh this when you compare fee models. A fee on profit costs nothing in a bad month. A fee on every order costs the same in good and bad months, but it never takes a share of a large gain.

Approving the fee

Hyperliquid only charges a builder fee that you have approved. You do this once, when you connect your account in the CryptoBoost app.

1. Approve the API wallet. This first signature lets the bot place and cancel orders for you. It cannot withdraw or transfer funds.
2. Approve the fee. A second signature, from the same main wallet, approves CryptoBoost to charge up to 0.1% per order. Hyperliquid accepts this approval only from your main wallet; an API wallet cannot sign it.

Until you approve the fee, the bot does not open new positions for you. If you connected by pasting a key, you will need a browser wallet to sign this approval.

The 0.1% cap is enforced by Hyperliquid itself, not just promised by CryptoBoost. Hyperliquid rejects any order that carries a higher fee than you approved. 0.1% is also the most Hyperliquid allows on perpetuals.

Revoking the fee

You can remove the approval at any time on Hyperliquid's Builder Codes page at app.hyperliquid.xyz/builderCodes (More → Builder Codes). Once it is removed:

• The bot stops opening new positions for you.
• It still closes any open position, without the fee, so revoking never leaves you stuck in a trade.
• The CryptoBoost app shows a button to approve the fee again if you want to resume.

When you disconnect, there is no final bill to settle. Fees were already paid order by order. See when to pause or disconnect a trading bot.

How to check what you paid

You can recalculate the fee from Hyperliquid's own records:

1. List the bot's fills for the period in your Hyperliquid Trade History.
2. Multiply each fill's value (size × price) by 0.1%.
3. Add them up. The total is what CryptoBoost earned from your account in that period, except for closes sent without the fee after a revoke.

Hyperliquid's fill records also report the builder fee on each fill separately from its own trading fee. The full method for reading fills is in how to verify fills and PnL.

How this compares with other fee models

Your Hyperliquid trading fees and funding are separate. They are charged by Hyperliquid, whatever fee model a bot uses.
