Question 1

What is a Hyperliquid builder code and how much can it earn?

Accepted Answer

A builder code lets any front-end or app that routes orders to Hyperliquid attach its own fee to each trade and collect it on-chain. The fee is capped at 0.1% (10 basis points) for perpetuals and 0.1% for spot, and it is charged on top of the exchange's own maker and taker fees, so it is pure revenue to the builder. The maths is simple: your revenue is your routed notional volume multiplied by your builder fee. A front-end pushing 10 million dollars of volume a day at a 0.05% builder fee earns 5,000 dollars a day, about 150,000 a month and roughly 1.8 million a year. The program has already paid out more than 80 million dollars to builders, and around 40% of Hyperliquid's daily active users now trade through third-party front-ends, so the volume being monetised this way is real. This calculator turns your own volume and fee into daily, monthly and annual revenue and shows where the break-even sits.

Question 2

How is the builder fee actually set on Hyperliquid?

Accepted Answer

The fee parameter is specified in tenths of a basis point. A value of 10 equals one basis point, which is 0.01%; a value of 100 equals ten basis points, which is 0.1% and is the maximum for perpetuals. So if you want to charge 0.05% you set the parameter to 50. The user has to approve a maximum builder fee for your address once, after which every order you route can carry a fee up to that approved ceiling. Because it is opt-in per user and visible on-chain, most successful front-ends keep the fee modest — often half a basis point to two basis points — and make it up on volume rather than charging the full ten-basis-point cap, which would roughly triple a taker's cost. This calculator lets you enter the fee in basis points directly and see both your revenue and the extra cost you are adding for the trader.

Question 3

What volume do I need to cover my app's running costs?

Accepted Answer

That is the break-even question, and it is the one most builders skip. Take your monthly operating cost — servers, data, salaries, whatever it takes to run the front-end — and divide it by your builder fee as a decimal and by the number of trading days in the month. The result is the daily routed volume you need just to break even. For example, an 8,000 dollar a month operation charging one basis point needs about 2.67 million dollars of routed volume every day before it makes a cent of profit. Enter your fee and your monthly cost and this calculator prints that break-even daily volume, then compares it to the volume you are actually routing so you can see whether the builder code is a real business or a rounding error.

Question 4

Does the builder fee make trading more expensive for my users?

Accepted Answer

Yes, and it is worth being honest about it. The builder fee is added on top of Hyperliquid's base fees — roughly 0.045% taker and 0.015% maker on perps — so a one-basis-point builder fee raises a taker's cost from 0.045% to 0.055%, and the full ten-basis-point cap would push it to 0.145%, more than triple. On a 10,000 dollar position a one-basis-point fee costs the trader one dollar to open and another to close. That sounds trivial, but active traders round-trip large size many times a day, which is exactly why the fee adds up to real revenue for you — and to a real cost for them. This calculator shows the trader's total per-side cost and the extra dollars per trade next to your revenue, so you can price the fee at a level that funds the app without quietly making it the most expensive place to trade.
