If you trade crypto futures regularly, reducing trading fees can make a noticeable difference in your long-term profits. One referral code that is commonly promoted online is “KUMAR”, which is advertised as offering up to 10% off trading fees on Hyperliquid.

This guide explains how to use the Hyperliquid referral code “KUMAR,” how fee discounts work, and what you should verify before trading.

What is Hyperliquid?

The platform is popular for:

What is the Referral Code “KUMAR”?

The referral code “KUMAR” is promoted on several crypto-related websites as a referral or invite code that may provide users with a 10% discount on trading fees.

Referral codes on Hyperliquid generally work by:

Linking your account or wallet to a referrer
Activating fee discounts or referral benefits
Reducing the cost of eligible trades

However, multiple sources also note that actual referral discounts on Hyperliquid may vary depending on platform policy and active promotions. Some sources indicate the standard referral discount is closer to 4% rather than 10%.

Because promotions can change, users should always confirm the active fee discount directly inside their account.

Step-by-Step: How to Use Hyperliquid Referral Code “KUMAR”
Step 1: Visit the Official Hyperliquid Platform

Go to the official website:

Hyperliquid Platform

Always double-check the website URL to avoid phishing websites or fake referral pages.

Step 2: Connect Your Crypto Wallet

Unlike centralized exchanges, Hyperliquid does not use traditional email registration.

Instead, you:

Connect a Web3 wallet
Approve wallet access
Use the wallet as your trading identity

Common wallets include MetaMask and other compatible Web3 wallets.

Step 3: Find the Referral or Invite Section

During onboarding or account setup, look for sections such as:

Referral Code
Invite Code
Rewards
Referral Settings

This is where you can apply the code.

Step 4: Enter the Code “KUMAR”

Type the referral code exactly as shown:

KUMAR

Then confirm or activate the code before you begin trading.

Several guides note that referral codes may only work during the initial wallet connection or first signup.

Step 5: Verify the Fee Discount

After activation:

Check the “Rewards” or “Fee Discount” section
Review your fee tier
Place a small test trade if needed

Some sources recommend confirming whether the discount is truly applied instead of assuming it activated automatically.

Why Traders Use Referral Codes

Using referral codes can help traders:

Reduce long-term trading costs
Improve net profitability
Save more during high-frequency trading
Lower expenses on leveraged trades

Even small fee reductions become meaningful for traders executing many transactions daily.

Important Things to Know
Promotions Can Change

Crypto referral programs are frequently updated. A code that works today may not work later.

Some Sources Mention Lower Official Discounts

Independent referral trackers and community discussions often reference a 4% official Hyperliquid referral discount instead of 10%.

Referral Codes Do Not Reduce Trading Risk

Even with discounted fees, perpetual futures trading remains highly risky because of:

Volatility
Leverage exposure
Liquidation risk

Always use proper risk management.

Final Thoughts

The Hyperliquid referral code “KUMAR” is promoted as a way to receive up to 10% off trading fees on Hyperliquid. Using the code is usually simple: connect your wallet, enter the referral code during signup, and verify the discount inside your account.

However, because referral promotions may change over time, it is important to confirm the active discount directly on the platform before trading. Combined with careful trading strategies and proper risk management, referral fee savings can help improve overall trading efficiency.
