How do you register with OKX? Six steps: open the referral link → enter an email and password → check the code reads NOVA888 → complete KYC → deposit and trade → bind your UID on the rebate site. Its 0.08% spot maker fee is a fifth below the 0.10% charged by Binance, Bybit, Gate and Bitget (WEEX and MEXC charge 0%), so limit-order traders are a fifth better off before any rebate. Bind through Quant Nova and that 20% is guaranteed to come back to you, independent of tier; anything beyond it cannot be published under OKX policy — ask support.
Three things to know before you sign up
- A referral code can only be entered at signup — it cannot be added later. This is what most people discover too late. Get it wrong or skip it and rebinding is your only route.
- KYC is not optional. An unverified account is feature-limited and cannot generate a calculable rebate.
- Registering is not the same as earning rebates. The code decides Layer 1; Layer 2 needs your UID bound on the rebate site — two things, two places.
OKX's affiliate terms only allow 20% to be advertised publicly, so the OKX column on this site reads "20% + ▨". What is masked is the part that cannot be stated publicly, not a part that does not exist — click it for an explanation.
About the referral code
The exchange charges you a fee either way. A referral code does not cost you a cent extra — it decides how much of that fee comes back. No code means that 20% becomes someone else's commission and you get nothing.
And Layer 1's 20% is not automatic just because you used a code — the referrer decides how much to pass on, and setting it to 0% is perfectly legitimate. Plenty of YouTuber and KOL codes are configured exactly that way. With NOVA888, that 20% is guaranteed to reach you.
OKX registration, step by step
Step 1: open the referral registration link
Use the "Register" button on this page to open OKX's official signup form; the link already carries the code NOVA888. If you register manually, type it into the "referral code" field yourself.
Step 2: enter an email or phone number and set a password
Use an address you actually check, set a strong password, and turn on 2FA immediately. Exchange accounts are rarely lost because the platform was breached — they are lost to reused passwords with no second factor.
Step 3: confirm the code reads NOVA888
Check the referral field once more before submitting. This step decides every rebate you will ever earn on the account, and it cannot be changed afterwards.
Step 4: complete KYC
Have your ID ready for document and face verification; it usually takes minutes to a day. Photograph the document with all four corners visible, no glare and no cropping, and make sure the name and date of birth you type match the document exactly — those two are the most common reasons for rejection.
Step 5: deposit and start trading
Deposit in crypto or through a fiat channel. Always confirm the network before an on-chain transfer — USDT exists on TRC20, ERC20, BSC and others, and assets sent on the wrong chain are usually unrecoverable. Once you trade, every fee starts accruing something that can come back to you.
Step 6: bind your UID on the rebate site
Log in, click your avatar top right — the UID is a plain string of digits. Copy it, go to the Quant Nova rebate dashboard, pick OKX, paste and submit. Binding needs only the UID: no API key, no password, no withdrawal permission. Your assets stay in your own exchange account throughout.
What will you pay in fees?
A rebate is a percentage of the fee, so knowing what comes back starts with knowing what you pay. OKX's list rates for regular users (VIP 0):
| Product | Maker | Taker | Token discount |
|---|
| Spot | 0.08% | 0.10% | OKB, by holdings |
| USDT-M futures | 0.02% | 0.05% |
Every market order is a taker order, so at the same notional a limit-order trader pays considerably less. The table reflects August 2026 list pricing and may change; current rates are on the official OKX fee page.
How much rebate will you get?
The rebate comes in two layers, from completely different places:
| Layer | Who pays it | Rate | Requirement |
|---|
| Layer 1: auto rebate | OKX | 20% | Sign up with referral code NOVA888 |
| Layer 2: extra rebate | The rebate site (Quant Nova) | By tier | Bind your UID on the rebate site |
Your tier is set by XP, and XP is simply the fees you have paid in the last 30 days, in USDT — pay 500 USDT in fees and you have 500 XP. No conversion.
On 500 USDT of monthly fees, Layer 1 alone is 100 USDT — the floor you are guaranteed regardless of volume or tier. What actually posts will be more.
The top "Supernova" tier cannot be reached by trading volume. It is invitation-only, reserved for accounts of a certain size, and arranged case by case.
What about the signup bonus?
Every exchange advertises a welcome package — bonuses, trial funds, mystery boxes — and the headline numbers look large. In practice these almost always come with conditions: a minimum deposit, a volume target inside a window, and rewards that are usually non-withdrawable trial credit or fee coupons that expire if unused.
Treat it as a one-off bonus, not as a reason to pick an exchange. What actually drives long-run cost is the fee and the rebate, because those happen on every single trade. You collect a signup bonus once; you collect rebates for as long as you trade. The actual terms are whatever OKX's own campaign page says — we make no promises about them.
Already have a OKX account?
The code cannot be backfilled, but you can "rebind" an existing account under NOVA888. On OKX there is an official re-binding application, the 180-day dormant-account recall and other routes, each with its own conditions; for the full conditions, steps and risks see the OKX rebinding guide.
Five mistakes people make
- Skipping the code, assuming it can be added later. It cannot. That is the single most important line in this guide.
- Assuming the code alone produces a rebate. That is only Layer 1. Layer 2 needs the UID bound on the rebate site.
- Binding the wrong UID. The UID is a numeric account ID — not a nickname, not an email. Sub-account commission rolls up to the master account's UID, so binding the master is enough.
- Depositing on the wrong chain. USDT lives on several; assets sent on the wrong one are usually gone. Check the network on both sides first.
- Not turning on 2FA. No rebate rate saves an account that gets taken over.
FAQ
Do I have to use a referral code on OKX?
It is not compulsory, but without one you get no rebate at all and it cannot be added later. Using NOVA888 costs you nothing extra.
Where do I enter NOVA888?
The link from the button on this page carries it automatically. Registering manually, type it into the "referral code" field — and check it once before submitting.
How long does registration take? Can I trade the same day?
The account itself takes minutes; KYC usually takes minutes to a day. Once KYC clears you can deposit and trade.
Is KYC required?
Yes. Unverified accounts are feature-limited, and the rebate cannot be calculated without it.
Does registering, binding or claiming cost anything?
No, all of it is free. A rebate returns part of a fee you were going to pay anyway; Quant Nova charges nothing on top.
Do I have to hand over an API key? Is it safe?
No. Only the UID — no API key, no password, no withdrawal permission. Your assets stay in your own OKX account; the rebate site neither custodies nor can move them.
I already have an account — can I still earn rebates?
Yes, through rebinding rather than backfilling the code. See the rebinding guide.
When does the rebate arrive?
After the exchange's daily report lands we import it, match each row to your UID and compute rebate and XP — typically posting to your rebate balance from T+1 onwards, visible and withdrawable.
Is there a minimum withdrawal threshold?
There is no lockup. The balance accrues on the rebate site and can be withdrawn whenever you like.
Can I register with several exchanges at once?
Yes, and it is worth doing. Trade wherever suits, watch every rebate in one dashboard; tier and XP are tracked per exchange. See the full eight-exchange comparison.
