Trading Fees
These are the current rates on Hyperliquid mainnet, paid in real funds. Rates can change, so treat the numbers here as a guide to how costs work and confirm the live values in the app before you rely on an exact figure. To practice without real funds, use testnet.
A deployed strategy sends every order to Hyperliquid, and every order carries three costs from three different places. Synchronicity trades on Hyperliquid mainnet, so these costs are paid in real funds. Knowing which is which up front means you set the cost deliberately instead of discovering it after a fill prints.
This page separates the three. The trade itself pays the exchange. Synchronicity adds a thin builder fee on top of the trade. Signac, the AI assistant, runs on its own meter and never touches your fills. The order in which they apply is at the bottom of the page.
Where the fees come from
Synchronicity is where you compose, test, and deploy the strategy. It is not the exchange. When an Order node runs, the trade executes on Hyperliquid, and Hyperliquid is where the actual buy or sell settles. So the first and largest cost on any trade is the exchange’s own trading fee.
On top of that single trade, two Synchronicity-specific costs can apply. One is the builder fee, a small amount added to the order through Hyperliquid’s builder-code mechanism.
Signac also has a limit on its usage. However this usage is not charged to your account.
Each section below takes one of the three apart.
Hyperliquid trading fees
The trade pays Hyperliquid. Because every Order node executes on Hyperliquid, the maker and taker fees on your fills are Hyperliquid’s own schedule, charged by the exchange. Synchronicity does not set them, mark them up, or restate them here.
That schedule depends on whether your order adds or removes liquidity (maker versus taker), your recent volume, and any rate tier you qualify for. Those numbers change, and the exchange is the only authoritative source for them.
Read the current schedule in Hyperliquid’s official fee documentation .
A market order that takes liquidity costs more than a resting limit order that provides it. If your strategy leans on taker fills, the exchange fee is the largest cost you carry. Read the schedule before you scale size.
Synchronicity builder fee
When Synchronicity sends an order to Hyperliquid, it can attach a builder code, Hyperliquid’s native way for an interface to charge a small fee alongside a trade. When you connect, you approve a cap on that builder fee with its own signature, separate from the agent approval, so the ceiling is fixed and visible up front.
The cap and the current per-order defaults:
| Surface | Builder fee |
|---|---|
| Approved cap (the ceiling) | 10 bps (0.1%) |
| Direct trades | 1 bp (current default) |
| Strategy orders | 3 bps (current default) |
A basis point (bps) is one hundredth of a percent. Ten basis points is 0.1%, the most Synchronicity can ever charge per trade under the approval you sign. The cap is only a maximum. The rate actually applied is lower and depends on how the order was placed.
The strategy and direct-trade rates are set through configuration, so treat the figures above as the current defaults rather than fixed constants. They can move up to the 10 bps ceiling. Confirm the live rate against the app before you rely on an exact number.
The 10 bps you approve is only a ceiling; nothing is charged up front. It is the maximum builder fee Hyperliquid will let Synchronicity attach to any single order, signed once and enforced by the exchange. The fee actually applied is lower. By default that is 3 bps on a strategy order and 1 bp on a direct trade, both configurable and both well under the cap.
- Direct trades placed by hand carry a 1 bp builder fee by default, the thinnest line on the page.
- Strategy orders sent by a deployed strategy carry a 3 bps builder fee by default, well under the cap. That rate can change, but the 10 bps you approved stays the ceiling.
Because the cap is signed once and enforced by Hyperliquid, no order can exceed it, whatever happens downstream.
Signac usage
Signac, the AI assistant inside the builder, runs on a separate meter. Signac usage is metered rather than charged as a trading fee: it is measured while you build a strategy and has nothing to do with what trades or what fills.
A usage widget shows your current Signac usage as you work. Heavy back-and-forth and web searches draw down more than a quick question, and if you reach a limit, Signac tells you in the chat. See Building with Signac for how the meter behaves while you compose.
Signac usage is metered separately from trading fees. It is not charged or deducted from your Hyperliquid balance.
What you pay, in order
For a single trade sent by a deployed strategy on Hyperliquid mainnet, the costs stack like this and are paid in real funds:
- Hyperliquid trading fee. The exchange’s maker or taker fee on the fill, set by Hyperliquid’s schedule. The largest line on most trades. See Hyperliquid’s fees .
- Synchronicity builder fee. By default 3 bps on a strategy order and 1 bp on a direct trade, both configurable, capped at 10 bps by the builder-fee approval you signed (a separate second signature from the agent approval).
- Signac usage. A separate meter, drawn down while you build. Not a trading fee and not charged to you.
