Hyperliquid Builder Codes & Builder Fees Explained (2026)

A builder fee is an extra charge a front-end app adds on top of Hyperliquid’s normal maker/taker fee. The app sets it per order, you have to pre-approve a maximum before it applies, and the protocol caps it at 0.1% on perpetuals and 1% on spot. It is how wallets and trading apps built on Hyperliquid make money without running their own exchange.

If you only ever trade on the official Hyperliquid front-end, you never pay a builder fee. But the moment you route orders through a third-party app — a mobile wallet, a copy-trading tool, a Telegram bot — that app can attach its own code to your fills and take a cut. Most people approve this once during onboarding and forget it exists. This guide explains exactly what you agreed to and how to check it.

For the base fee schedule underneath all of this, see our Hyperliquid fees guide.

What Builder Codes Actually Are

Hyperliquid lets any developer register as a “builder.” A builder gets a code they can attach to orders they submit on a user’s behalf. When a fill happens, the builder earns the fee they set on that order, paid straight to their wallet on-chain.

The design is deliberate. Hyperliquid runs an on-chain order book and directs all protocol fees to the community (the HLP vault, the assistance fund, and deployers). It does not take a corporate cut. So there is no revenue for the third-party apps that bring users in. Builder codes fix that: they give app developers a native, transparent way to charge for the service they provide instead of hiding a markup in the spread.

You approve a builder once, set a ceiling on what they can charge, and every order that app sends carries that fee up to your ceiling.

The Fee Caps

The protocol enforces hard limits so a builder cannot drain you:

Market	Maximum builder fee
Perpetuals	0.1% (10 basis points)
Spot	1% (100 basis points)

The fee parameter is expressed in tenths of a basis point in the API, so a value of 100 equals 10 bps, which is the perp ceiling. Builder fees apply to both sides of a perp trade (open and close) but not to the buy side of a spot trade.

In practice, almost no serious app charges the maximum. Competitive front-ends set builder fees in the 0.01% to 0.05% range on perps, because a 0.1% builder fee would more than double the total cost of trading and users would notice. The 1% spot cap is there for edge cases, not everyday routing.

How Builder Fees Stack on Top of Protocol Fees

This is the part that matters for your bottom line. The builder fee is separate from and added to the normal maker/taker fee. Here is what a base-tier perp taker actually pays through a third-party app:

Cost layer	Rate	On a $10,000 taker order
Protocol taker fee	0.045%	$4.50
Builder fee (typical)	0.02%	$2.00
Builder fee (worst case, capped)	0.10%	$10.00
Total (typical builder)	0.065%	$6.50

A 0.02% builder fee lifts your effective taker cost from 0.045% to 0.065% — roughly a 44% increase over trading on the native front-end. At the capped 0.1%, your cost more than triples. That gap is the whole reason to check what your app is charging before you route size through it.

HYPE staking and VIP tier discounts only reduce the protocol fee. They do nothing to the builder fee, which is set by the app and sits outside Hyperliquid’s discount system.

Why $10M+ Went to Builders in 2026

Builder codes stopped being a niche API feature in 2026. The Hyperliquid Foundation set aside roughly $10 million to support builders, tied in part to ecosystem shifts like the planned USDH sunset. The goal was to pull more front-ends, wallets, and automated tools onto Hyperliquid by giving them a real revenue model.

It worked. A meaningful share of Hyperliquid’s volume now arrives through third-party apps rather than the official site, and those apps collectively earn millions in builder fees. For traders, that means more choice in interface — but also more places where a fee you did not read about gets attached to your orders.

How to Check and Revoke a Builder Approval

You are always in control of the ceiling. When an app asks you to approve builder fees, you sign a message setting the maximum fee that builder can charge. You can change or revoke it whenever you want.

To review what you approved:

• Open the Hyperliquid front-end and go to your account or API settings.
• Look for the approved builder fee section. It lists each builder address and the max fee you granted.
• Any app that routes your orders will appear here with its ceiling.

To revoke:

• Set the approved maximum for that builder back to zero, or use the app’s own “revoke” flow.
• Once revoked, that app can no longer attach a fee to your fills. It may also stop working until you re-approve, since many third-party front-ends require a builder approval to function.

If you see a builder approval you do not recognize, revoke it. A legitimate app discloses its fee up front; a code you never knowingly approved is a red flag.

Builder Fees vs Referral Codes vs Rebates

These three get confused constantly. They are not the same thing.

Mechanism	Who pays	Who earns	Effect on you
Builder fee	You	The app/front-end	Adds cost on top of protocol fee
Referral code	Protocol	The referrer + you	Discounts your protocol fee
Maker rebate	Protocol	You (the maker)	Pays you for providing liquidity

A referral code lowers what you pay. A builder fee raises it. If an app markets itself with a referral discount but also charges a builder fee, net the two out before deciding it is cheaper. A 4% referral discount on a 0.045% fee saves you $0.18 per $10K; a 0.05% builder fee on the same order costs you $5. The builder fee dominates.

Should You Care About Builder Fees?

For most people trading small size occasionally, a 0.02% builder fee is a few cents and not worth switching apps over — the better interface or copy-trading feature can be worth it. But three groups should pay close attention:

• Active traders. If you turn over six or seven figures a month, a 0.02% builder fee is real money. Route high-volume trades through the native front-end or an app with a minimal builder fee, and keep the fancy app for its non-trading features.
• Copy traders. Copy-trading tools often charge a builder fee plus a performance cut. Read both before you allocate.
• Anyone who onboarded through a bot or wallet. You may be paying a builder fee you never consciously agreed to. Check your approvals.

The healthy way to think about it: the protocol fee is Hyperliquid’s price, and the builder fee is your app’s price. Both are legitimate, both are on-chain and transparent, and both are your choice. You just have to know the second one exists.

FAQ

Do I pay a builder fee on Hyperliquid?

Only if you trade through a third-party app that has registered a builder code and that you have approved. Trading on the official Hyperliquid front-end charges no builder fee — you pay only the standard protocol maker/taker fee.

What is the maximum builder fee on Hyperliquid?

The protocol caps builder fees at 0.1% (10 basis points) on perpetuals and 1% (100 basis points) on spot. Most competitive apps charge far less than the cap, usually 0.01% to 0.05% on perps.

How do I remove a Hyperliquid builder fee?

Go to the builder fee approval section in your Hyperliquid account settings, find the builder address, and set its approved maximum to zero (or use the app’s revoke flow). The app can no longer charge you after that, though it may stop functioning until you re-approve.

Does HYPE staking reduce builder fees?

No. HYPE staking and VIP volume discounts only lower the protocol fee. Builder fees are set by the third-party app and sit outside Hyperliquid’s discount system, so they are unaffected by staking.

Are builder fees the same as referral discounts?

No, they are opposites. A referral code lowers your protocol fee; a builder fee adds an extra charge on top of it. If an app offers a referral discount but also charges a builder fee, compare the two — the builder fee usually costs more than the referral saves.
