Hyperliquid builder fees: how apps charge you, and the limit you control
A builder fee is how an app built on Hyperliquid gets paid: a small percentage added to orders it sends for you, inside a maximum that only your main wallet can set.
In private testing: the trading engine is not live yet. The console you can open today shows sample data and nothing is traded. These pages describe how Helmsman is built to work.
How it works
Each order can name a builder address and a fee rate. Before that is accepted, your main wallet must approve a maximum rate for that builder. An order asking for more than your maximum is rejected by the exchange.
The fee is collected by Hyperliquid at the fill and recorded on it, so your fill history shows exactly what each trade paid.
The limits
- On perpetuals the exchange caps builder fees at 0.1%. Your approved maximum can only be at or below that.
- Only your main wallet can approve or raise a maximum. An API wallet cannot.
- You can have approvals for up to ten builders at once, and you can revoke any of them.
Reading a rate
Rates are small, so turn them into money. 0.03% is $3.00 per $10,000 traded; 0.05% is $5.00. It is charged on the order’s value, on the way in and on the way out.
Helmsman’s numbers
Helmsman asks you to approve a 0.05% maximum and charges 0.03%. It has no other income: no subscription, no share of results.
