How to Register on HTX 2026: nova888 Code, Up to 50% Rebate

How do you register on HTX (formerly Huobi)? Six steps: open the dedicated link that carries the referral code → sign up with email or phone and set a password → expand "Referral Code (Optional)" and check it reads nova888 in lowercase → complete KYC as needed → deposit and trade → bind your UID on Quant Nova. Most referral codes you will find pay 20% (some 25%); when you bind through Quant Nova, nova888 pays 40% on futures from Lv.1 and up to 50% — 2 to 2.5 times a common code. On 1,000 USDT of monthly fees, a common 20% code returns 200 USDT while nova888 returns 400–500 USDT, which is 200–300 USDT more every month.

Key takeaways

• The referral code is all-lowercase nova888: not the uppercase NOVA888 used on other exchanges. Getting the case wrong is the same as leaving it blank.
• The field is collapsed by default: "Referral Code (Optional)" on the HTX sign-up page only shows once you open it, so expand it before you submit.
• The rebate is 2 to 2.5 times a common code: through Quant Nova, futures pay 40% → 50% and spot 40% → 45%; a common code pays 20%.
• Spot at 0.2% is on the high side of the twelve: the same volume costs more in fees, so the rebate you get back is larger too.
• Bind your UID after signing up: the code goes in on HTX, the UID gets bound on Quant Nova. You need both for the full rebate.

Three things to know before you sign up

• The HTX referral code can only be entered at sign-up; there is no public way to add it once the account exists.This is what most people discover too late, so get it right the first time.
• Lowercase nova888 is the same as WEEX; the others are uppercase. If you are used to typing NOVA888 on Binance, Bybit or Bitget, switch to all lowercase on HTX and type it exactly.
• HTX is the old Huobi. Huobi announced its rebrand to HTX in September 2023. An old Huobi account is today's HTX account, so there is no need to sign up again.

HTX (Huobi) registration steps

Step 1: Open the dedicated link with the referral code

Use the sign-up button on this page to reach HTX's official registration page; the dedicated link already carries nova888. You can also click "Sign Up" from the HTX homepage, but then you have to type the code yourself. Either way, run the check in Step 3 before you submit.

Step 2: Choose email or phone and set a password

Per HTX's official guide, on the web you click "Sign Up" on the official site, choose email or phone number, set a login password, pass the anti-bot check and enter the verification code sent to your email (or phone). In the app you go to "Me" and then Log In / Sign Up; the flow is the same (see HTX's official sign-up guide). Use a password you have not used anywhere else, and turn on two-factor authentication (2FA) right away.

Step 3: Expand "Referral Code (Optional)" and check it reads nova888

This is the step that matters most. HTX labels the field "Referral Code (Optional)" and it is collapsed by default, so you cannot see what is in it until you open it. Expand it and confirm it reads lowercase nova888; if it is empty, type it in. Once you submit, the referral relationship is fixed and cannot be changed, so look before you click "Next".

Step 4: Complete KYC as needed

HTX identity verification has three levels (see HTX's official KYC guide):

1. L1 Basic: nationality, ID number, name and date of birth, with no face scan or ID photo. It lifts the withdrawal limit from 2 BTC per day without KYC to unlimited.
2. L2 Primary: upload a passport, ID card or driver's licence to raise deposit and crypto-purchase limits.
3. L3 Advanced: face recognition, for higher limits still.

Most people only need L1 or L2. Make sure all four corners of the document are visible with no glare and that your details match the document; review goes faster that way.

Step 5: Deposit and start trading

Transfer crypto in from another exchange or a wallet. Always confirm the network before an on-chain transfer (for USDT, TRC20 or ERC20, for example); assets sent on the wrong network are usually lost. Once you start trading, every fee you pay starts building up the amount that comes back to you.

HTX has a broad product line: spot, margin, USDT-M and coin-M futures, copy trading, trading bots and earn products. Per HTX's public API, on 2026-09-24 there were 604 spot pairs online and 357 USDT-M contracts trading. Any trade that generates a fee earns a rebate; earn products that charge no trading fee have nothing to rebate.

Step 6: Find your UID and bind it on Quant Nova

The UID is the numeric ID of your HTX account. After logging in you can see it on your profile (account info) page, usually with a copy button next to it. Copy it, go to the Quant Nova rebate site, choose HTX, paste the UID and submit. Binding needs only your UID: no API key, no password and no withdrawal permission.Your assets stay in your own HTX account throughout. More on UIDs in What a UID is and where to find it.

How much will you pay in fees?

A rebate is a percentage of your fees, so first see what you pay. HTX list rates for regular users (Prime 0):

Fees verified on 2026-09-24 (each exchange's official fee schedule).

The latest rates are on HTX's official fee page. HTX also offers token deductions: paying with HTX takes 25% off spot and margin fees and up to 10% off futures; you can use TRX instead (25% off spot, 5% off futures). Only one can be active at a time, switched under Profile > My Fee Rates. A deduction lowers the list rate, and the rebate then returns part of what you actually paid, so the two stack.

On futures: HTX's user agreement (updated 2026-09) bars derivatives for users in some jurisdictions, including Taiwan, Israel and New Zealand, and does not serve places such as mainland China, Hong Kong, the US, the UK or EU member states. Check yours in the HTX user agreement before trading futures.

How much rebate do you get after signing up?

When you bind through Quant Nova, HTX rebates work out as follows; spot and futures have different caps:

The full rate for each tier is in the table below:

On 1,000 USDT of monthly fees: a common 20% code returns 200 USDT; nova888 futures return 400 USDT at Lv.1 and up to 500 USDT. Over a year the difference is 2,400–3,600 USDT.

The effective rate makes it clearer. A 0.06% futures taker fee after a 50% rebate is 0.06% × (1 − 50%) = 0.03%; at Lv.1's 40% it is 0.036%, and with a common 20% code it is 0.048%. Spot at 0.2% after a 45% rebate is 0.2% × (1 − 45%) = 0.11%; Lv.1 gives 0.12% and a common code 0.16%.

The high 0.2% spot fee is exactly where a rebate claws back the most: 100,000 USDT of monthly spot volume costs 200 USDT in fees, of which a common 20% code returns 40 USDT, while nova888 returns 80 USDT at Lv.1 and up to 90 USDT.

For futures (only where derivatives are allowed), assume 70% taker and 30% maker, a blended rate of 0.7 × 0.06% + 0.3 × 0.02% = 0.048%:

Figures are USDT per month. The top 50% is the invitation-only Supernova tier; the highest you reach through volume is SVIP at 45%, and Lv.1 starts at 40%.

Settlement is simple: the 20% set on the referral code is returned by HTX automatically, and the rest is settled by Quant Nova according to your tier. It can be paid by HTX internal transfer straight to your bound UID (HTX's internal-transfer minimum is 1 USDT), with no on-chain withdrawal.

How to think about new-user rewards

Under HTX's official referral rules, invited new users can take part in a Mystery Box worth up to 1,500 USDT and/or a Welcome Bonus Pack worth up to 1,200 USDT (see HTX's official referral rules). These usually come with deposit or volume conditions, are mostly trial funds or vouchers, and expire if unused. The actual terms are on HTX's campaign page.

Treat sign-up rewards as a one-off bonus. What drives your long-term cost is the fee and rebate on every single trade: the welcome gift arrives once, the rebate arrives every month.

Five most common mistakes

• Typing uppercase NOVA888. HTX uses lowercase nova888; the habit from other exchanges will not bind.
• Submitting without expanding the field. "Referral Code (Optional)" is collapsed by default; open it and check before clicking "Next".
• Assuming you can add it later. HTX has no public way to add a code afterwards; enter it at sign-up.
• Entering the code but not binding the UID. The code goes in on HTX; the UID has to be bound separately on Quant Nova. Skip that and the rebate is incomplete.
• Binding the wrong UID. The UID is a numeric account ID, not a nickname, email or phone number.

Already have an HTX account?

HTX publishes no rule for adding a code later or switching referrers, and a referral binding cannot be changed. If you already have an account that was not opened with nova888, rebind by registering a new account through the signup link with lowercase nova888: withdrawals work without KYC up to 2 BTC per day, and L1 basic verification makes them unlimited. See the HTX rebind guide. The rules for all twelve exchanges are collected in Exchange referral rebinding rules.

Bottom line: who should sign up for HTX with nova888?

If you already plan to trade on HTX, sign up with lowercase nova888 and bind your UID on Quant Nova to get 2 to 2.5 times the rebate of a common 20% referral code. HTX's 0.2% spot fee is high, which is exactly where the rebate shows up most.

Where derivatives are allowed, futures rebates reach 50%; elsewhere, focus on spot. Sign up with nova888 now and your rebate starts building from your very first trade.For more on entering the code see HTX referral code nova888; WEEX, which also uses a lowercase code, is covered in WEEX referral code.

If you are still deciding where to trade most, start with the fee and rebate comparison of twelve exchanges: HTX futures rebates top out at 50%, the same band as Bitget, while XT.COM and WEEX reach 70% on futures through Quant Nova. Using several exchanges for different kinds of trades is fine; all rebates show in one dashboard, while tiers and XP are counted separately per exchange.

Frequently asked questions

What is the HTX referral code?

It is all-lowercase nova888. The dedicated link fills it in automatically; if you sign up manually, type it into the "Referral Code (Optional)" field.

Are HTX and Huobi the same exchange?

Yes. Huobi announced its rebrand to HTX in September 2023, and your old Huobi account is now your HTX account.

Can I add a referral code after registering on HTX?

No. HTX has no public way to add one later, so enter it at sign-up; if you already have an account, rebind by registering a new one with lowercase nova888; see the HTX rebind guide.

How much rebate does nova888 give on HTX?

When you bind through Quant Nova, futures pay 40% at Lv.1 and up to 50%, and spot pays 40% and up to 45%, which is 2 to 2.5 times a common 20% referral code.

Is KYC mandatory on HTX?

Not necessarily. You can withdraw without KYC up to 2 BTC per day; L1 Basic (nationality, ID number, name, date of birth, with no face scan or ID photo) makes withdrawals unlimited. L2 and L3 are optional.

Can everyone trade futures on HTX?

No. HTX's user agreement (updated 2026-09) bars derivatives in some jurisdictions, including Taiwan, so check yours before trading futures.

Is binding my UID safe?

Yes. Binding needs only your UID, with no API key, password or withdrawal permission, so Quant Nova cannot touch the assets in your account.

When does the rebate arrive?

After the exchange's daily report is produced, each trade is matched to your UID and the rebate and XP are calculated; it usually lands in your Quant Nova balance from T+1, where you can check it and withdraw it by HTX internal transfer.
