Register OKX with referral code NOVA888 for a permanent 20% auto-rebate (OKX charges the fee, then refunds 20% to your account). If you already have an OKX account, you can rebind it to the rebate platform (Quant Nova). This guide covers why a code can't be added after signup, the four ways existing users rebind, how the rebate is paid and calculated, and the tier table.
What do you get by registering OKX with NOVA888?
- A permanent 20% auto-rebate, refunded directly to your account by OKX (charge-first, refund-after).
- A one-stop rebate data platform: once bound, track every rebate, your balance, tier and XP on the rebate platform (Quant Nova), and request withdrawals.
- An exclusive extra offer besides the 20%, based on your tier (OKX policy only allows advertising 20% publicly — contact support for your actual maximum).
- Referral code NOVA888 — dedicated registration link.
A typical KOL code also gives 20%; the difference is that through Quant Nova you can see every rebate and tier on the data platform and ask support about an exclusive offer beyond the 20%, whereas a KOL keeps the rest.
How is the OKX rebate paid and calculated? (charge-first, refund-after)
In one line: OKX charges the trading fee as usual, then refunds 20% of it to your account afterwards.
Example: using OKX's 0.05% perp taker rate with 2,500 USDT margin at 20x leverage, the notional is 50,000 USDT and the one-side fee is 50,000 × 0.05% = 25 USDT. The 20% auto-rebate = 25 × 20% = 5 USDT refunded to your account (see the complete fee-rebate guide).
The same fee also counts as experience points (XP), raising your rebate tier; the higher your tier, the better the exclusive extra rebate Quant Nova offers (contact support for the exact rate).

When do you need to rebind?
OKX only lets you enter a referral code when you create the account; it cannot be added afterwards. If your OKX account wasn't registered under our code, the system can't credit rebates to you — so you rebind: bind your existing account to NOVA888, and the fees you generate from then on start accruing rebates.
Four ways for existing OKX users to rebind
Option 1 (recommended, fastest)
Register a brand-new account using a family member's identity through the dedicated link and bind NOVA888.
Option 2
Leave the account idle for 180 days, then sign in through the dedicated link to complete the recall-and-rebind. This works whether or not the account was ever bound to someone else's code.
Option 3: OKX official rebind
OKX offers an official rebind request, typically requiring the account to be older than ~90 days with recent trading volume below a threshold (per OKX's own terms). Try Option 2 first; if it fails, use this. Steps:
- Open the rebind URL https://okx.com/ul/J6l2R5 (mainland China, no VPN: https://oyidl.me/ul/J6I2R5).
- Enter referral code NOVA888, and set the binding reason to "Joining Quant Nova".
- Submit, then wait for OKX to review it.
To improve approval odds, leave the account idle for 1–2 months before applying.
Option 4
Non-mainland-China users: closing your phone number and email for the first time lets you re-register. The first closure releases your KYC, which you can then re-verify on a new account.
Want a higher rebate?
OKX policy caps the advertised rebate at 20%. Beyond the 20% auto-rebate, we have exclusive extra OKX offers — to find out your actual maximum, contact support via the rebate platform (Quant Nova).
Frequently Asked Questions
Can I add an OKX referral code after signing up?
No. OKX only lets you enter a referral code when you create the account; it can't be added or changed afterwards. If you already have an account, use the rebind methods above.
What rebate do I get by registering OKX with code NOVA888?
A permanent 20% auto-rebate, refunded by OKX (charge-first, refund-after). Beyond that there is a tier-based exclusive extra rebate (OKX only advertises 20% publicly; contact support for your actual maximum).
When is the OKX rebate paid?
OKX uses charge-first, refund-after: it charges the fee at the time of the trade, then refunds 20% to your account. Once bound through Quant Nova, these rebates and XP are recorded on the rebate platform (Quant Nova) for you to track and withdraw.
How is OKX's 20% different from a KOL code?
OKX advertises a flat 20% for everyone; the difference is transparency and the extra offer — through Quant Nova's one-stop data platform you can see every rebate, tier and XP and ask support about an exclusive offer beyond the 20%, whereas a KOL code keeps the rest.
I already have an OKX account — can I still rebind?
Yes. See the four methods above. The most recommended are Option 1 (register a new account via the dedicated link using a family member's identity) and Option 2 (leave the account idle for 180 days, then recall-and-rebind).
What are the conditions and timing for OKX's official rebind?
OKX's official rebind (Option 3) typically requires the account to be older than a certain age with recent volume below a threshold (per OKX); after submitting you wait for OKX's review, and leaving the account idle for 1–2 months first improves your odds.
Do I still get OKX new-user rewards when registering with the code?
Yes. Registering with NOVA888 still qualifies you for OKX's official new-user rewards (such as mystery boxes; the exact contents and amounts follow OKX's own campaign).
After rebinding, when do rebates start?
Once you rebind and bind NOVA888, the fees you generate afterwards start accruing rebates and XP, which you can track on the rebate platform (Quant Nova).
