HTX Referral Code nova888 (2026): All Lowercase, 20% Auto-Rebate on Signup

Q: What do I do after using the code?

Bind your HTX UID on the Quant Nova rebate site . The code decides layer one's 20%; layer two only starts once your UID is bound. How tiers move up is covered in rebate tiers and XP .

The HTX (formerly Huobi) referral code is lowercase nova888, not the uppercase NOVA888 most exchanges use. Where to enter it, how the 20% auto-rebate works, why it matters more with 0.2% spot fees, and what binding your UID adds.

HTX referral code (invite code): nova888. The HTX code is nova888, all lowercase — the same as WEEX, while Binance, OKX, Bybit, Bitget and the others use uppercase NOVA888. This is the most common HTX signup mistake, so check the case before you submit.

HTX is the exchange formerly known as Huobi. Sign up with this code and HTX automatically returns 20% of your fees; bind your UID with Quant Nova and the extra rebate stacks on top by tier.

What is the HTX referral code?

The code is nova888 (lowercase). The button below uses a dedicated link that already carries it; registering manually means entering it yourself.

HTX — up to 50% fee rebate

Where do I enter it?

The referral field on HTX's signup page is collapsed by default, so you can't see what's in it until you open it:

Open the signup page through the link above and enter your email or phone number.
Click "Referral Code (Optional)" to expand the field.
Check it reads nova888 in lowercase; if it's empty, type it in.
Click "Next" and finish verification.

What kind of exchange is HTX?

HTX started as Huobi, founded in 2013, and announced its rebrand to HTX on 13 September 2023 — see HTX's official rebrand announcement.

Listed fees for regular users:

Market	Maker	Taker
Spot	0.2%	0.2%
Futures	0.02%	0.06%

The 0.2% spot fee is tied with XT.COM as the highest of the twelve exchanges we list. HTX's official fee page is authoritative.

How much does it earn?

In two layers:

Layer one: a 20% auto-rebate, set on HTX's side and returned by HTX straight to your account, without going through us.
Layer two: Quant Nova's extra rebate, added by tier once your UID is bound, per the table below:

Actual rates vary by tier and exchange; live figures are shown on the platform.

A futures example at 70% taker and 30% maker fills: blended rate 0.7 × 0.06% + 0.3 × 0.02% = 0.048%.

Monthly futures volume	Monthly fee	HTX 20% auto-rebate only	Per year
100,000 USDT	48 USDT	9.6	~115
500,000 USDT	240 USDT	48	576
2,000,000 USDT	960 USDT	192	2,304

The table counts layer one only. For layer two, take your tier's rate from the table above and run your volume through the fee rebate calculator to get both layers combined.

0.2% spot fees make the rebate count for more

At the same 100,000 USDT a month, HTX spot fees come to 200 USDT — more than four times the 48 USDT futures figure above — and layer one alone returns 40 USDT a month. On HTX spot, fees are the biggest cost you pay, and the rebate grows with them.

If you trade mostly spot at size, put HTX's 0.2% side by side with other exchanges' listed fees before deciding where your main account lives. Fees and codes for every exchange are in referral codes for every exchange.

The three ways people get this wrong

Typing uppercase NOVA888 out of habit. The HTX code is lowercase nova888; enter it exactly.
Clicking Next without expanding the field. "Referral Code (Optional)" is collapsed by default; open it and check it reads nova888 before submitting.
Assuming it can be added later. The code must go in at signup; it cannot be added once the account exists.

Already have an HTX account?

The code cannot be backfilled. Contact support first and we'll walk you through rebinding based on your account.

Frequently Asked Questions

Are HTX and Huobi the same exchange?

Yes. Huobi was founded in 2013 and renamed HTX in 2023.

Are the HTX referral code and invite code the same thing?

Yes. HTX's signup page labels the field "Referral Code (Optional)", and the code to enter is lowercase nova888.

Who pays the 20%?

HTX. Layer one's 20% is returned by HTX directly to your account; layer two is what Quant Nova pays by tier. The difference is explained in auto-rebate vs extra rebate.

What do I do after using the code?

Bind your HTX UID on the Quant Nova rebate site. The code decides layer one's 20%; layer two only starts once your UID is bound. How tiers move up is covered in rebate tiers and XP.
