How is a builder code different from a referral code?

A referral code gives users a fee discount when they sign up. A builder code adds a small fee on top of base fees that goes to the builder/developer. They serve different purposes but can stack — you can use both a referral code (like TRADEOFF4 for 4% off) and trade through a frontend with a builder code.

Does using a builder code cost me extra?

Yes, builder codes add a small fee on top of the standard Hyperliquid trading fees. The builder sets the fee rate when creating their code. Typical builder code fees range from 0.005% to 0.05% of trade value. You can avoid builder code fees by trading directly on the official Hyperliquid UI.

How do I apply a builder code?

Builder codes are automatically applied when you use a third-party frontend or trading tool that has integrated a builder code. You do not manually enter a builder code — it is embedded in the application you are using. The official Hyperliquid UI does not use any builder code.

How do I create my own builder code?

To create a builder code, you need to use the Hyperliquid API. Register your builder code through the API with your desired fee rate. You need a Hyperliquid account and basic development knowledge. The code is tied to your wallet address, and earnings are automatically deposited.

Can builder codes and referral codes stack?

Yes, builder codes and referral codes stack. The referral code discount is applied to the base trading fee, while the builder code fee is an additional charge. For example, with TRADEOFF4 (4% off base fees) and a builder code adding 0.01%, your total fee would be (base fee * 0.96) + 0.01%.

What Are Hyperliquid Builder Codes?

Builder codes are a unique feature of the Hyperliquid ecosystem that allows developers, frontend creators, and tool builders to earn revenue from the trades executed through their platforms. When a developer integrates a builder code into their application, a small additional fee is added to each trade, and this fee is shared with the builder.

Think of builder codes as a monetization mechanism for the Hyperliquid ecosystem. Just as app stores take a percentage from developer revenues, Hyperliquid builder codes allow frontend developers to earn a percentage from trades made through their interfaces. The key difference is that this is fully transparent and on-chain.

This system incentivizes the creation of innovative trading tools, analytics dashboards, copy trading platforms, and other applications built on top of Hyperliquid — ultimately benefiting all users through a richer ecosystem.

How Builder Codes Work

The builder code system operates through a straightforward fee-sharing mechanism. Here is how the flow works from end to end:

Developer Creates a Builder Code

A developer registers a builder code through the Hyperliquid API. They specify a fee rate (e.g., 0.01% or 1 basis point) that will be charged on trades executed through their platform. The code is linked to their wallet address.

Builder Code Is Integrated Into Frontend

The developer integrates their builder code into their trading interface, bot, or tool. When users trade through this frontend, the builder code is automatically attached to every order.

User Trades via the Frontend

When a trader places an order through the builder's frontend, the trade includes both the standard Hyperliquid base fee and the additional builder code fee. The user pays base fee + builder fee on each trade.

Builder Earns Revenue

The builder code fee is automatically routed to the builder's wallet. Revenue accrues in real-time and can be withdrawn at any time. The builder can track their earnings, volume, and user count through the API.

Fee Breakdown Example

For a $10,000 market order at VIP 0 tier through a frontend with a 0.005% builder code:

Base Fee (0.045%)

$4.50

Builder Fee (0.005%)

Builder Code vs Referral Code: Key Differences

Many users confuse builder codes with referral codes. While both are part of Hyperliquid's incentive structure, they serve fundamentally different purposes and work differently.

Feature	Builder Code	Referral Code
Purpose	Revenue sharing for builders/frontends	Fee discount for new users
Who Creates It	Developers, frontends, tools	Any existing user
Fee Impact	Adds a small fee on top of base fees	Provides a discount on trading fees
Revenue Flow	Builder earns from user trades	Referrer + referee share discount
Applied Via	API/Frontend integration	Signup link or code entry
User Benefit	Access to specialized tools/features	Direct fee discount (e.g., 4%)
Stacks With	Referral codes (both can be active)	Builder codes (both can be active)

Key Takeaway: Referral codes benefit the user (fee discount), while builder codes benefit the developer (revenue). Both can be active simultaneously. Use referral code TRADEOFF4 for a 4% fee discount regardless of which frontend you trade on.

How to Apply (or Avoid) a Builder Code

Unlike referral codes, you do not manually enter a builder code. It is automatically applied based on the frontend or tool you use to trade. Here is what you need to know:

Official Hyperliquid UI: No Builder Code

Trading through the official Hyperliquid interface at app.hyperliquid.xyz does NOT apply any builder code. You only pay the standard base trading fees. This is the cheapest way to trade.

Third-Party Frontends: Builder Code Applied

When you use a third-party trading tool, bot, or frontend built on Hyperliquid, a builder code is automatically attached to your trades. The additional fee varies by builder — typically 0.005% to 0.05%. Check the frontend's documentation or fee page to see their builder code rate.

API Trading: You Choose

If you trade via the Hyperliquid API directly, you can choose whether to include a builder code or not. Omitting the builder field from your API calls means no builder code fee. You can also set your own builder code if you are building a tool.

Get the Lowest Fees on Hyperliquid

Use referral code TRADEOFF4 for a 4% lifetime fee discount. Trade on the official UI to avoid extra builder code fees. Combine both for the absolute lowest trading costs.

Fee Structure with Builder Codes

Understanding how builder code fees stack with base fees and referral discounts is important for calculating your true trading costs. Here are some practical examples:

Scenario	Base Fee	Builder Fee	Ref. Discount	Final Fee
$10,000 Market Order (VIP 0)	$4.50	$0.50	-$0.18	$4.82
$10,000 Limit Order (VIP 0)	$1.50	$0.50	-$0.06	$1.94
$50,000 Market Order (VIP 0)	$22.50	$2.50	-$0.90	$24.10
$100,000 Market Order (VIP 2)	$36.00	$5.00	-$1.44	$39.56

Note: Builder code fees are charged IN ADDITION to base trading fees. The referral discount (TRADEOFF4 = 4%) only applies to the base fee, not the builder fee. To minimize total costs, trade on the official Hyperliquid UI (no builder fee) with TRADEOFF4 applied.

How to Create Your Own Builder Code

If you are a developer building tools on Hyperliquid, creating a builder code allows you to monetize your application. Here is how to set one up:

Set Up a Hyperliquid Account

You need a Hyperliquid account with a connected wallet. Visit app.hyperliquid.xyz/join/TRADEOFF4 to create your account. The builder code earnings will be deposited to this wallet.

Access the Hyperliquid API

Builder codes are registered through the Hyperliquid API. Review the API documentation at hyperliquid.gitbook.io to understand the builder code endpoints and parameters.

Register Your Builder Code

Use the API to register your builder code with your desired fee rate. Choose a competitive fee rate — too high and users will avoid your platform, too low and you will not earn meaningful revenue. Most successful builders charge 0.005% to 0.02%.

Integrate Into Your Frontend

Add your builder code to your trading interface or bot. When users trade through your platform, include the builder field in your API order submissions. The fee is automatically calculated and routed to your wallet.

Monitor and Optimize

Track your builder code performance through the API — volume generated, fees earned, unique users. Optimize your fee rate and frontend features to attract more traders and maximize revenue.

How Builder Codes Benefit the Ecosystem

Builder codes are not just a revenue tool — they are a fundamental part of Hyperliquid's strategy to grow a vibrant ecosystem of applications and tools. Here is why they matter:

Best Hyperliquid Codes for Traders

For most traders, the optimal setup is to use referral code TRADEOFF4 for a 4% fee discount and trade directly on the official Hyperliquid UI. Here is our recommended approach:

RECOMMENDED

Lowest Cost: TRADEOFF4 + Official UI

Sign up at app.hyperliquid.xyz/join/TRADEOFF4 for a permanent 4% discount on base trading fees. Trade through the official Hyperliquid UI, which has no builder code fee. This gives you the absolute lowest fees possible on Hyperliquid.

Total savings: 4% off all base fees, $0 builder code fees

For Advanced Tools: TRADEOFF4 + Third-Party Frontend

If you need advanced features like custom charting, automated strategies, or specialized order types, using a third-party frontend with a builder code is worthwhile. The builder code fee is a small price for powerful tools. Your TRADEOFF4 referral discount still applies to the base fee.

For API Traders: TRADEOFF4 + Direct API

If you trade via the API, you can omit the builder code field entirely — no extra fees. Combined with TRADEOFF4, this gives you the same low fees as the official UI. If you are building your own bot, consider adding your own builder code to monetize it.

Trade on Hyperliquid with the Lowest Fees

Use referral code TRADEOFF4 for a 4% lifetime fee discount. Avoid unnecessary builder code fees by trading on the official UI. Maximize your trading edge with the lowest possible costs.
