How builder fees flow
- A trader places a $10,000 order on your site.
- Your site attaches your builder address and a 0.01% fee.
- Hyperliquid executes the order, generating a $1 builder fee.
- Your contract collects the fee. Its address is your builder code.
- Floatout publishes the allocation. Each wallet claims its share.
- You, affiliates, traders receiving kickbacks and Floatout each claim their allocated share. This is an illustration after activation, not live transactions.
ILLUSTRATIVE FLOW · AFTER ACTIVATION
What is a Hyperliquid builder code?
A Hyperliquid builder code is an address and fee attached to a trading order. When that order fills, Hyperliquid credits the builder fee to the app's address, on top of its own trading fee. The trader first approves a maximum fee and can revoke that approval anytime.
Think of different apps as different entrances to the same market. Hyperliquid supplies the order books and executes the trades. Your app supplies the experience, your brand and your community. You can earn from the trading activity you bring in.
For example, $1 million in eligible trading volume at a 0.01% builder fee generates $100 in gross fees, before revenue shares and costs. Use the builder fee calculator to explore your own numbers.
Builder codes are different from referral codes, which track who invited a trader. They also do not require deploying a market through HIP-3. You can build a frontend for markets that already exist. That is the shortest way to launch a perp DEX without running an exchange.

Hyperliquid builder fees: limits and approvals
| Rule | How it works |
|---|---|
| Perpetual futures | Up to 0.1% (10 basis points), on buys and sells |
| Spot | Up to 1% (100 basis points), on sells |
| Trader approval | A gas-free signature sets the maximum. Revocable anytime |
| Builder account | At least 100 USDC in perps account value, using standard account mode |
These are Hyperliquid's official builder-code rules. Traders can manage permissions on its builder-code approvals page. Floatout handles the integration and funds the builder minimum as part of paid activation.
For developers: the order parameter
Orders carry an optional builder parameter: {"b": address, "f": fee}. The fee is in tenths of a
basis point, so f: 10 means 0.01%. Query maxBuilderFee for a trader's approved maximum. Builder fees use
Hyperliquid's referral-reward claim process.
Why Floatout uses a contract as your builder code
When you activate earnings, Floatout deploys a dedicated smart contract for your DEX. That contract's address becomes your builder code. It collects your fees and pays claims to the wallets in the published allocation.
- Referrals built in. Set a commission for your affiliate program. They can share part with the traders they invite, giving your community a reason to grow your platform.
- Direct claims. Affiliates and referred traders claim their allocated shares from the contract. You do not need to send each payment from your own wallet.
- A separate fee pool. Each activated DEX has its own contract and public builder address. Its fees are kept separate from other DEXes, with no owner withdrawal function.
- Traders keep their accounts. Their trading balances stay in their own Hyperliquid accounts, outside your fee contract. You do not take custody of customer deposits.
Floatout calculates and publishes payout allocations, and claims are subject to the contract's pause controls. See the security model for operator and upgrade permissions, and where traders' funds go.
Here is an example of how $100 in builder fees is shared when a trader joins through an affiliate. The commission and kickback are example rates:
- You claim from your contract
- $65
- Affiliate claims from the contract
- $15
- Referred trader claims a referral kickback
- $5
- Floatout platform share
- $15

Frequently asked questions
What are builder codes on Hyperliquid?
Builder codes let apps attach a builder address and fee to orders routed to Hyperliquid. The fee is charged on eligible fills, in addition to Hyperliquid's trading fee. Traders approve a maximum fee for each builder and can revoke that approval.
How much can a Hyperliquid builder charge?
Up to 0.1% on perpetual futures and 1% on spot sells, within each trader's approved maximum. At a 0.01% builder fee, $1 million of eligible trading volume generates $100 in gross builder fees, before revenue shares and costs.
Are builder codes the same as referral codes?
No. A builder code identifies the app receiving a fee on an order. A referral code attributes an invited trader. Floatout connects the two: after earnings activation, your referral program can share builder fees with affiliates and referred traders.
Does approving a builder fee cost gas?
No. It is a signed Hyperliquid action from the trader's main wallet, not an EVM transaction. A trader can approve up to 10 builders at once and revoke approvals on Hyperliquid's builder-code page.
Can I launch a Hyperliquid trading platform for free?
Yes. Preview your brand without a wallet, then connect and sign in to publish with Floatout. Starter uses Floatout's builder code, so fees go to Floatout. Activate earnings with a one-time payment when ready. Your share starts after activation, with no retroactive earnings or monthly fee on self-serve plans.
